Description

本発明は、種々の汚水の無排水処理を行う汚水処理装置及び前記汚水処理装置を使用して水洗トイレ排水を処理する無排水トイレ装置に関するものである。   The present invention relates to a sewage treatment apparatus that performs non-drainage treatment of various sewage and a non-drainage toilet apparatus that treats flush toilet drainage using the sewage treatment apparatus.

無排水トイレ装置としては、特許文献1,2(特開平5−230858号公報、特開2000−170227号公報)に示すとおり、接触曝気槽での微生物による汚物の分解と、分解処理後の滅菌処理を行い、処理済み水を水洗トイレ洗浄用水として再度使用することを繰り返す循環方式のものが知られている。   As an undrained toilet device, as shown in Patent Documents 1 and 2 (Japanese Patent Laid-Open Nos. 5-230858 and 2000-170227), decomposition of filth by microorganisms in a contact aeration tank and sterilization after the decomposition treatment are performed. A circulation system is known that performs treatment and repeats reuse of treated water as flush toilet water.

更にトイレ排水の処理残存水(処理対象水)を蒸発処理する手段として、特許文献3(特開2002−119988号公報)には、周面にパンチ孔(空気孔)を形成した蒸発反応層内に濾過材を多段に形成し、処理対象水の微生物処理と蒸発を同時に行う手段が開示されている。   Further, as a means for evaporating the residual treatment water (treatment target water) of toilet drainage, Patent Document 3 (Japanese Patent Application Laid-Open No. 2002-199988) includes an evaporation reaction layer in which punch holes (air holes) are formed on the peripheral surface. Discloses a means for forming filter media in multiple stages and simultaneously performing microbial treatment and evaporation of water to be treated.

また特許文献4(特開2005−262077号公報)には、処理対象水を土壌中に浸透させて、土壌表面(植栽物)からの蒸発を行うと共に、前記土壌層の下方に余剰水の滞留槽を設け、前記滞留層からポンプアップして前記土壌表面に散水したり、トイレ洗浄用水として使用することが開示されている。   In Patent Document 4 (Japanese Patent Laid-Open No. 2005-262077), water to be treated is infiltrated into the soil to evaporate from the soil surface (plants), and excess water is provided below the soil layer. It is disclosed that a staying tank is provided and pumped up from the staying layer to spray water on the soil surface or used as toilet cleaning water.

前記した無排水トイレ装置においては、処理水の再利用のための大型装置が必要であり、且つ多額のランニングコストが必要であり、また設置コストも高いという問題がある。   The undrained toilet apparatus described above has a problem that a large apparatus for reusing treated water is necessary, a large running cost is required, and an installation cost is high.

また前記した蒸発処理方式において、特許文献4に開示されている方式は、処理に必要な適度の面積の土地が必要であり、そのような広い土地を使用できない状況においては対応することができず、且つ土壌に埋設する恒常的な設備が必要であり、臨時的或いは短期的な処理施設を必要とする場合にも対応できない。   In addition, in the above-described evaporation processing method, the method disclosed in Patent Document 4 requires a land with an appropriate area necessary for the processing, and cannot cope with a situation where such a large land cannot be used. In addition, permanent equipment buried in the soil is necessary, and it is not possible to cope with a case where a temporary or short-term treatment facility is required.

また前記の特許文献3記載の蒸発処理方式は、屋外設置型であるが、処理対象水の流入量変動に対しては、溢流対策のみが考慮されており、濾過材が処理対象水で満たされると好気発酵処理がスムーズになされないし、濾過材の通水性を高めてしまうと、処理対象水の発酵処理が為されずに未処理のまま蒸発槽を通過してしまい、そのまま処理済み水として、再利用されてしまう虞がある。   Moreover, although the evaporation treatment method described in Patent Document 3 is an outdoor installation type, only measures against overflow are taken into account for fluctuations in the amount of inflow of water to be treated, and the filter medium is filled with the water to be treated. If the aerobic fermentation process is not performed smoothly, and the water permeability of the filter medium is increased, the water to be treated passes through the evaporating tank without being subjected to the fermentation process, and has been processed as it is. There is a risk of being reused as water.

そこで本発明は、確実な蒸発処理を行って無排水とする汚水処理装置及び前記汚水処理装置を使用した無排水トイレ装置を提案したものである。   Therefore, the present invention proposes a sewage treatment apparatus which performs a reliable evaporation process to make no drainage and an undrained toilet apparatus using the sewage treatment apparatus.

本発明(請求項1)に係る汚水処理装置は、通気性を有する外箱内に、処理対象水を受け入れると共に、適宜な通水性を有し、且つ微生物処理可能となる多孔状態に形成される部材で満たした通水分解処理部と、前記通水分解処理部の周囲に通水分解処理部から処理対象水が浸透して湿潤状態で微生物処理がなされると共に、蒸発処理がなされる蒸発分解処理部とを設け、前記通水分解処理部内に汚水溜容器を配設すると共に、前記汚水溜容器から毛細管現象で蒸発分解処理部へ汚水を浸透させて湿潤状態とする浸透布を配置し、外箱下方に余剰水の排出部を設けてなるボックス体を、単一或いは多段で構成する蒸発分解部と、前記蒸発分解部からの余剰水を貯留する下方タンクと、蒸発分解部の上方に配置され、下方タンク貯留水をポップアップして貯留し、適時蒸発分解処理部に処理対象水として供給する上方タンクとを備えてなることを特徴とするものである。 The sewage treatment apparatus according to the present invention (Claim 1) is formed in a porous state in which water to be treated is received in an outer casing having air permeability, has appropriate water permeability, and can be treated with microorganisms. A water-flow decomposition treatment unit filled with members, and the water to be treated penetrates from the water-flow decomposition treatment unit to the periphery of the water-flow decomposition treatment unit to perform microbial treatment in a wet state and evaporative decomposition in which evaporation treatment is performed. A treatment unit, and a waste water storage container disposed in the water flow decomposition processing unit, and an osmotic cloth that wets the waste water from the waste water storage container to the evaporative decomposition processing unit by capillary action to make it wet. A box body provided with a discharge portion of excess water below the outer box, a single or multi-stage evaporative decomposition section, a lower tank for storing excess water from the evaporative decomposition section, and an upper portion of the evaporative decomposition section Placed and popped downward tank reservoir water -Up and then stored in and is characterized by comprising a upper tank for supplying the water being treated in a timely manner the evaporation separation processor.

而して処理対象水をボックス体(蒸発分解処理部)に送り込むと、処理対象水は、通水処理部を適宜滞留しながら浸透通過すると共に、通水処理部から周囲の蒸発分解処理部に浸透して湿潤状態(微生物の繁殖の最適状態)とする。通水処理部及び蒸発分解処理部では、共にその構成部材に付着した微生物によって分解処理が行われると同時に、前記部材において特定の物質を吸着する部材を混合することで、例えば汚水中の金属イオンを吸着させて汚水の浄化を行う。   Thus, when the water to be treated is fed into the box body (evaporative decomposition treatment unit), the water to be treated penetrates and passes through the water treatment unit as appropriate, and from the water treatment unit to the surrounding evaporative decomposition treatment unit. Infiltrate into a wet state (optimal state for microbial growth). In the water flow treatment unit and the evaporative decomposition treatment unit, the decomposition process is performed by the microorganisms adhering to the constituent members at the same time, and at the same time, by mixing the member that adsorbs a specific substance in the member, for example, metal ions in sewage The sewage is purified by adsorbing water.

更に外箱の外周から微生物処理のための空気が流入するが、同時に前記の空気は蒸発分解処理部の処理対象水が蒸発する。そして蒸発分解処理部で水分蒸発がなされると、通水処理部から更に処理対象水が浸透して、微生物による分解処理と、蒸発処理が継続的になされるものである。   Further, air for microbial treatment flows from the outer periphery of the outer box, but at the same time, the water to be treated in the evaporative decomposition treatment unit evaporates. When water is evaporated in the evaporative decomposition treatment unit, the water to be treated is further permeated from the water flow treatment unit, and the decomposition treatment by the microorganisms and the evaporation treatment are continuously performed.

特に通水処理部における保水能力を超えて処理対象水が送り込まれると、余剰水として排出部から排出されて下方タンクに溜まり、下方タンクに溜まった余剰水は上方タンクに送られ、再度蒸発分解処理部で微生物分解処理と蒸発処理を行うもので、無排水で処理対象水(汚水)の処理を行うことができる。   In particular, when the water to be treated is sent in excess of the water retention capacity in the water flow treatment unit, it is discharged from the discharge unit as surplus water and collected in the lower tank, and the surplus water collected in the lower tank is sent to the upper tank and again evaporative decomposition The treatment unit performs microbial decomposition treatment and evaporation treatment, and can treat water to be treated (sewage) without draining.

前記の汚水処理においては、通水分解処理部に保水能力以上の処理対象水が送り込まれると、汚水溜容器に処理対象水が一旦溜められ、蒸発分解処理部において処理対象水の蒸発が行われるのに対応して、浸透布の毛細管現象で汚水溜容器内の処理対象水が順次蒸発処理部に浸透して補給されていくので、処理対象水の生物分解処理及び蒸発処理が継続することになる。   In the sewage treatment, when the water to be treated having a water retention capacity or more is sent to the water splitting treatment unit, the water to be treated is temporarily stored in the sewage reservoir, and the water to be treated is evaporated in the evaporative decomposition treatment unit. In response to this, the water to be treated in the sewage reservoir is sequentially permeated into the evaporating unit due to the capillary phenomenon of the osmotic cloth, and is replenished. Become.

また本発明(請求項2)に係る汚水処理装置は、前記の汚水処理装置において、蒸発分解部を、複数のボックス体を多段に積層して構成すると共に、ボックス体の通水分解処理部又は蒸発分解処理部の一方又は双方の構成部材を異ならせてなるものである。 Further, in the sewage treatment apparatus according to the present invention ( claim 2 ), in the sewage treatment apparatus, the evaporative decomposition unit is configured by laminating a plurality of box bodies in multiple stages, One or both constituent members of the evaporative decomposition processing unit are made different.

従って予めボックス体の通水分解処理部及び蒸発分解処理部の構成部材や微生物等を上下段異なるものを採用すると、汚水の種別・内容の変化に対しても対応でき、また種々の有害物質の除去も可能となり、蒸発されずに最終的に残る排出水が存在したとしても、その浄水化が実現し、残余排出水の有効利用が可能となる。   Therefore, by adopting different components in the upper and lower stages, such as the components and microorganisms of the water-flow decomposition treatment section and evaporative decomposition treatment section of the box body, it is possible to cope with changes in the type and content of sewage, and various harmful substances. Even if there is drainage water that remains without being evaporated, it can be purified, and the residual drainage water can be used effectively.

また本発明(請求項3,4)に係る汚水処理装置は、前記のボックス体の外周を凹凸面に形成して、空気との接触面積を大きくしたり、ボックス体の外周に溝孔を形成し、蒸発分解処理部に基方を埋設した蒸発促進布を前記溝孔より外部上方に向けて突出させてなるもので、湿潤処理部に含まれる汚水の蒸発が促進されるものである。 Further, in the sewage treatment apparatus according to the present invention ( claims 3 and 4 ), the outer periphery of the box body is formed in an uneven surface to increase the contact area with air, or the groove is formed in the outer periphery of the box body. Further, the evaporation promoting cloth having the base embedded in the evaporative decomposition treatment part is projected outward from the groove hole, and the evaporation of sewage contained in the wet treatment part is promoted.

本発明(請求項5)に係る無排水トイレ装置は、前記した汚水処理装置と、トイレ排水を処理して液体を排出する固液分離処理部と、圧送ポンプを付設して、トイレ排水を固液分離処理部に排出する水洗トイレとで構成されることを特徴とするものである。 A non-drained toilet apparatus according to the present invention ( Claim 5 ) includes the above-described sewage treatment apparatus, a solid-liquid separation processing unit that processes toilet drainage and discharges the liquid, and a pressure pump, thereby fixing the toilet drainage. It is comprised with the flush toilet discharged | emitted to a liquid separation process part.

而して水洗トイレのトイレ排水は、圧送ポンプで固液分離処理部に送られ、固液分離処理部で生物分解処理と固液分離がなされ、固液分離処理部で分離した汚水(処理対象水)は、汚水処理装置での生物分解処理と蒸発処理が行われ、トイレ排水は外部に排出することなく処理されるものである。   Thus, the toilet drainage of the flush toilet is sent to the solid-liquid separation processing unit by a pressure feed pump, subjected to biodegradation processing and solid-liquid separation in the solid-liquid separation processing unit, and the sewage separated by the solid-liquid separation processing unit (treatment target) Water) is subjected to biodegradation treatment and evaporation treatment in a sewage treatment apparatus, and toilet wastewater is treated without being discharged to the outside.

また本発明(請求項6)に係る無排水トイレ装置は、前記の無排水トイレ装置において、特に下方タンクに雨水又は河川水等の中水供給機構を付設すると共に、上方タンクからトイレ洗浄用水を、水洗トイレに供給してなるものである。 The drainage toilet apparatus according to the present invention ( Claim 6 ) is the drainage toilet apparatus according to the present invention, in particular a rainwater or river water or other medium water supply mechanism is attached to the lower tank, and toilet cleaning water is supplied from the upper tank. , Supplied to flush toilets.

即ち下方タンクに雨水・河川水等を集めて中水として利用することができ、特に蒸発処理部の余剰水(浄化水)を雨水と共に利用することができる。   In other words, rainwater, river water, etc. can be collected in the lower tank and used as middle water, and in particular, surplus water (purified water) of the evaporation processing section can be used together with rainwater.

また本発明(請求項7)に係る無排水トイレ装置は、前記の中水によるトイレ洗浄を行う装置において、特に水洗トイレの排水部分をトラップ構造とし、且つ清浄水と中水を供給可能とし、トイレ洗浄に際して、中水洗浄後に清浄水を供給し、トイレ使用後に水洗トイレに清浄水が滞留するようにしたものである。




Moreover, the non-draining toilet device according to the present invention ( Claim 7 ) is a device for performing toilet cleaning with the above-mentioned middle water, and in particular, the drainage portion of the flush toilet has a trap structure and can supply clean water and middle water. In toilet cleaning, clean water is supplied after washing with medium water so that the clean water stays in the flush toilet after using the toilet.




而して前記の無排水トイレ装置においては、トイレ使用後のトイレ洗浄を始めに中水を使用して汚物を流し、その後に清浄水を供給すると、清浄水がトイレ(便器)に残り、次の使用者に対し不快感を与えない。   Thus, in the above-described non-drained toilet device, when the filth is poured using the middle water at the beginning of the toilet cleaning after the use of the toilet and then the clean water is supplied, the clean water remains in the toilet (toilet bowl), and the next Do not give discomfort to users.

本発明の構成は上記のとおりで、汚水処理を蒸発と生物分解と有害物質吸着で行う蒸発処理部(ボックス体)を備えると共に、ボックス体における通過水を再循環させて確実な蒸発処理を実施して、完全無排水処理を実現したものである。   The configuration of the present invention is as described above, and includes an evaporation processing unit (box body) that performs sewage treatment by evaporation, biodegradation, and adsorption of harmful substances, and performs reliable evaporation processing by recirculating the water passing through the box body. Thus, complete drainage treatment is realized.

また特にボックス体内に汚水溜容器と浸透布を配置することで、間欠的に汚水供給が為されたとしても、蒸発処理と生物分解処理等を継続的に且つ適切に行うことができ、トイレ排水などの無排水処理を簡易な設備で実現できたものである。   In particular, by disposing a sewage reservoir and a permeation cloth inside the box, even if sewage is supplied intermittently, evaporation and biodegradation can be performed continuously and appropriately, and toilet drainage The wastewater treatment such as can be realized with simple equipment.

次に本発明の実施形態について説明する。実施形態は無排水トイレ装置について説明した。   Next, an embodiment of the present invention will be described. The embodiment has been described with respect to an undrained toilet apparatus.

実施形態の無排水トイレ装置は、汚水処理装置を構成する蒸発処理部1及び下方タンク2、及び上方タンク3と、トイレ装置として付加される水洗トイレ部4及び固液分離処理部5で構成される。   The drainage toilet apparatus of the embodiment includes an evaporation processing unit 1 and a lower tank 2 and an upper tank 3 that constitute a sewage treatment device, and a flush toilet unit 4 and a solid-liquid separation processing unit 5 added as a toilet device. The

蒸発処理部1は、本発明の特徴とするところで、ボックス体1a,1b,1c・・・を多段に構成したもので、各ボックス体1a,1b,1c・・・は、各々通気性を有する外箱11と、通水分解処理部12と、蒸発分解処理部13と、汚水溜容器14と、浸透布15と、排水部16とで構成される。   The evaporation processing unit 1 is a feature of the present invention, and the box bodies 1a, 1b, 1c... Are configured in multiple stages, and each box body 1a, 1b, 1c. The outer box 11, the water passage decomposition processing unit 12, the evaporative decomposition processing unit 13, the sewage reservoir 14, the permeation cloth 15, and the drainage unit 16 are configured.

外箱11は、多数の小透孔111を穿設すると共に、内方周面に不織布の様な通気布112を添わせ、蒸発分解処理部13が零れ出るのを防止しているものである。   The outer box 11 is provided with a large number of small through holes 111 and a ventilation cloth 112 such as a non-woven fabric attached to the inner circumferential surface to prevent the evaporative decomposition treatment unit 13 from spilling out. .

通水分解処理部12及び蒸発分解処理部13は、土、砂、砂利、木炭、貝殻砕片等任意の部材で構成されるもので、適宜な通水性(保水性)を備えた多孔状態となるように、外箱11内に充填されているもので、通水分解処理部12は、処理対象水(汚水)Aの通水路を構成すると共に、適宜な保水性を有して、構成部材に付着した微生物で汚水Aを分解処理及び金属などの吸着処理を行う。   The water flow decomposition treatment unit 12 and the evaporative decomposition treatment unit 13 are composed of arbitrary members such as soil, sand, gravel, charcoal, shell fragments, and are in a porous state with appropriate water permeability (water retention). In this way, the outer casing 11 is filled, and the water decomposition treatment unit 12 constitutes a water passage for the water to be treated (sewage) A and has an appropriate water retention capacity as a constituent member. The sewage A is decomposed and adsorbed with metal or the like with the attached microorganisms.

蒸発分解処理部13は、前記通水分解処理部12の周囲に設けられるもので、汚水が浸透して湿潤状態で、微生物が繁殖すると共に、微生物による分解処理が行われ、同時に外箱11の小透孔111から水分が蒸発する。   The evaporative decomposition processing unit 13 is provided around the water flow decomposition processing unit 12, and the microorganisms propagate while the sewage penetrates and is in a wet state, and the decomposition process is performed by the microorganisms. Water evaporates from the small through holes 111.

また図4に例示するように、ボックス体1a,1b,1c・・・の外箱11の側面を、凹凸形状にして、周面における空気接触面積を大きくすると、前記の蒸発が促進される。更に外箱11の側面に溝孔113を穿設し、前記溝孔113から支持板114を斜め上方に突出させて、前記溝孔113に蒸発促進布115を挿通すると共に、基方側を蒸発分解処理部13内に埋め込み、外側を前記支持板114に載置して外箱11の外方に張り出させるようにすると、前記の蒸発処理が一層促進される。   Further, as illustrated in FIG. 4, when the side surfaces of the outer box 11 of the box bodies 1 a, 1 b, 1 c... Are made uneven to increase the air contact area on the peripheral surface, the evaporation is promoted. Further, a slot 113 is formed in the side surface of the outer box 11, the support plate 114 protrudes obliquely upward from the slot 113, the evaporation promoting cloth 115 is inserted into the slot 113, and the base side is evaporated. If it is embedded in the decomposition processing unit 13 and the outside is placed on the support plate 114 so as to protrude outward from the outer box 11, the evaporation process is further promoted.

また特に上下に積層されるボックス体1a,1b,1c・・・の通水分解処理部12及び蒸発分解処理部13は、その構成部材や微生物等が異なるものを採用すると、分解処理対象や吸着物質(除去物質)の多様性を得ることができる。   In particular, the water-flow decomposition processing unit 12 and the evaporative decomposition processing unit 13 of the box bodies 1a, 1b, 1c,. Diversity of substances (removable substances) can be obtained.

汚水溜容器14は、前記の通水分解処理部12内に配置したもので、単一或いは多段に複数埋設しても良いし、上方を開口状態で配置しても良い。この汚水溜容器14には、浸透布15の一端側を貯留した汚水Aに浸るようにし、前記浸透布15の他方端側を蒸発分解処理部13内となるように配置したものである。   The sewage reservoir 14 is disposed in the water flow decomposition processing unit 12 and may be embedded in a single or multiple stages, or may be disposed in an open state on the upper side. In this sewage reservoir 14, one end side of the osmotic cloth 15 is immersed in the stored sewage A, and the other end side of the osmotic cloth 15 is disposed in the evaporative decomposition treatment unit 13.

排水部16は、外箱11の底面に皿状受け部161と流下口162を備えると共に、流下口162から通水分解処理部12及び蒸発分解処理部13の構成部材が落下しないように、フェルト等の透水布163で流下口を塞ぐようにしている。   The drainage part 16 is provided with a dish-shaped receiving part 161 and a flow-down opening 162 on the bottom surface of the outer box 11, and felt so that constituent members of the water flow decomposition treatment part 12 and the evaporative decomposition treatment part 13 do not fall from the flow-down opening 162. The flow-down mouth is closed with a water-permeable cloth 163 such as the above.

尚、排水部16は、皿状受け部161等を採用することなく、ボックス体1a,1b,1c・・・の底方に、図4に例示するような小透孔を穿設した水抜き管16aを配置して排水部としても良い。   In addition, the drainage part 16 does not employ | adopt the dish-shaped receiving part 161 grade | etc., But the drainage which drilled the small through-hole which was illustrated in the bottom of the box bodies 1a, 1b, 1c ... It is good also as a drainage part by arrange | positioning the pipe | tube 16a.

而して前記の蒸発処理部1においては、汚水(処理対象水)Aが、ボックス体1aの上方中心から放水されると、その重力で通水分解処理部12に浸透していくと共に、一部はその内部の汚水溜容器14に溜まる。   Thus, in the evaporation processing unit 1, when the sewage (treatment target water) A is discharged from the upper center of the box body 1 a, it penetrates into the water flow decomposition processing unit 12 due to its gravity. The part accumulates in the sewage reservoir 14 inside.

同時に通水分解処理部12の保水限界を越えると、蒸発分解処理部13に浸透する共に、更に浸透量を越える分は排水部16から排出されて次段のボックス体1bに送られ、順次同様に処理される。   At the same time, if the water retention limit of the water splitting treatment unit 12 is exceeded, it penetrates into the evaporative decomposition processing unit 13 and further exceeds the permeation amount is discharged from the drainage unit 16 and sent to the box body 1b in the next stage, and so on. To be processed.

通水分解処理部12及び蒸発分解処理部13において、浸透した汚水Aは、その有機物等は両分解処理部12,13の構成部材に付着した微生物によって分解処理(好気性処理)がなされ、また前記部材に特定の物質を吸着する部材を混合することで、例えば汚水中の金属イオンを吸着して汚水の浄化がなされる。   In the permeable water treatment unit 12 and the evaporative decomposition treatment unit 13, the permeated sewage A is subjected to a decomposition treatment (aerobic treatment) by microorganisms adhering to the constituent members of both the decomposition treatment units 12 and 13, By mixing a member that adsorbs a specific substance to the member, for example, metal ions in the sewage are adsorbed to purify the sewage.

前記の好気性処理の空気供給は、屋外放置の外箱11に対して吹く風によってなされるが、同時に前記の空気は蒸発分解処理部13の汚水Aを蒸発させる。蒸発分解処理部13に含まれる汚水Aが蒸発しても、汚水溜容器14内の汚水Aが浸透布15の毛細管現象で蒸発分解処理部13に浸透して、汚水Aの生物分解処理及び蒸発処理が継続することになる。汚水Aの供給量が多く通水分解処理部12の保水能力及び汚水溜容器14の貯留能力を越えた場合には、排水部16から次段のボックス体1bに排出され、次段のボックス体1bでも同様の汚水Aの生物分解処理及び蒸発処理が行われることになる。   The air supply for the aerobic treatment is performed by the wind blown to the outer box 11 left outdoors, and at the same time, the air evaporates the sewage A of the evaporative decomposition treatment unit 13. Even if the sewage A contained in the evaporative decomposition processing unit 13 evaporates, the sewage A in the sewage reservoir 14 penetrates into the evaporative decomposition processing unit 13 due to the capillary phenomenon of the osmotic cloth 15, and biodegradation processing and evaporation of the sewage A Processing will continue. When the supply amount of the sewage A is large and exceeds the water retention capacity of the water splitting treatment unit 12 and the storage capacity of the sewage storage container 14, it is discharged from the drainage unit 16 to the next box body 1b, and the next box body In 1b, the same biodegradation process and evaporation process of the sewage A are performed.

従って前記のボックス体1a,1b,1c・・・の段数や容量は、トイレ装置の設計値(仮想使用程度:処理能力)に対応して定められるものであるが、ボックス体1a,1b,1c・・・は持ち運びでき、且つ容易に多段に組み込むことができると屋外設置が容易になされるが、前記の蒸発処理部1で全て蒸発処理が確実になされるものではないので、その対応として、下記の下方タンク2と上方タンク3を設けてなる。   Accordingly, the number of stages and the capacity of the box bodies 1a, 1b, 1c,... Are determined in accordance with the design value of the toilet device (virtual use level: processing capacity), but the box bodies 1a, 1b, 1c. ... can be carried and can be easily installed in multiple stages, but it can be easily installed outdoors, but not all of the evaporation processing unit 1 can reliably perform evaporation processing. The following lower tank 2 and upper tank 3 are provided.

下方タンク2は、蒸発処理部1で蒸発処理されなかった余剰水(排水部16から排水)Bを受け入れるもので、内部に水位センサ(図示せず)と送水ポンプ21を内設し、上方タンク3は、水位センサ(図示せず)を内装して蒸発処理部1の上方に配置し、下方タンク2と上方タンク3との間は、第一循環路31で接続し、上方タンク3と蒸発処理部1との間に第二循環路32を介設したものである。   The lower tank 2 receives surplus water (drainage from the drainage section 16) B that has not been evaporated by the evaporation processing section 1, and has a water level sensor (not shown) and a water pump 21 provided therein, and an upper tank. 3 includes a water level sensor (not shown) and is disposed above the evaporation processing unit 1. The lower tank 2 and the upper tank 3 are connected by a first circulation path 31, and the upper tank 3 is evaporated. A second circulation path 32 is interposed between the processing section 1 and the processing section 1.

そして上下タンク2,3の両水位センサの検知に応じて、下方タンク内の貯留水(前記余剰水B又は後述の中水C)を上方タンク3に送り出し、上方タンク3から第二循環路32を通して蒸発処理部1に落水させて、蒸発処理を行うことで、汚水Aの完全な蒸発処理を実現することができるものである。   Then, in response to detection by both water level sensors in the upper and lower tanks 2 and 3, the stored water (the surplus water B or middle water C described later) in the lower tank is sent to the upper tank 3, and the second circulation path 32 is supplied from the upper tank 3. By passing the water through the evaporation processing unit 1 and performing the evaporation process, a complete evaporation process of the sewage A can be realized.

更に、基本的に汚水(トイレ汚水)Aは蒸発処理部1で蒸発処理を行い、余剰水Bの発生を抑えるように設計し(余剰水Bが発生しても前記の通り対応できる)、蒸発処理部1を水洗トイレの洗浄用水として使用する中水Cの浄化用としても使用できるようにした。   Furthermore, basically, the sewage (toilet sewage) A is subjected to an evaporation process in the evaporation processing unit 1 and designed to suppress the generation of surplus water B (even if surplus water B is generated, it can be dealt with as described above) and evaporate. The treatment section 1 can be used for purifying the middle water C used as washing water for flush toilets.

即ち下方タンク2には、中水供給機構22を付設したもので、中水供給機構22は、例えばトイレ装置を設置する近傍の建築物の屋根、適宜範囲の地面上に設けた集水施設で形成される雨水受け等の他、周囲の河川水や沢水等を導入路等を構築して形成するものである。   In other words, the lower tank 2 is provided with a middle water supply mechanism 22, which is a water collection facility provided on the roof of a nearby building where a toilet device is installed, for example, on an appropriate range of ground. In addition to the rainwater receptacles and the like that are formed, the surrounding river water and river water are constructed by constructing an introduction path and the like.

上方タンク3には、後述する水洗トイレ部4に対して洗浄用水Dを供給するものである。具体的に説明すると、集水施設である雨水受け(中水供給機構)22からの雨水(中水)Cは、下方タンク2に送られ貯留されることになる。勿論下方タンク2は、雨水Cを受け入れ易いように低所に設置するもので、内部の送水ポンプ21で高所に設置した上方タンク3に送水するものである。   The upper tank 3 is for supplying cleaning water D to a flush toilet section 4 to be described later. More specifically, rainwater (middle water) C from a rainwater receiver (middle water supply mechanism) 22 that is a water collection facility is sent to the lower tank 2 and stored. Of course, the lower tank 2 is installed in a low place so that rainwater C can be easily received, and is supplied to the upper tank 3 installed in a high place by an internal water pump 21.

前記の送水(ポンプアップ)に際しては、両タンク2,3に内設した水位センサの検知値に基づいて送水ポンプ21の作動を制御し(空回り等を防止する)、また第一循環路31には、散水管23を分岐させて、植物の灌漑用水としての利用も可能とする。   At the time of the water supply (pump up), the operation of the water supply pump 21 is controlled based on the detection value of the water level sensor installed in both tanks 2 and 3 (prevents idling), and the first circulation path 31 The water sprinkling pipe 23 is branched to enable use as irrigation water for plants.

上方タンク3は、前記の送水ポンプ21の作動によって、一定以上のトイレの洗浄用水Dを確保し、水洗トイレ部4に対する洗浄用水供給路33を設け、水洗トイレ部4からの信号(便器付属の水槽のフロート弁による動作指示)で一定の洗浄用水Dを水洗トイレ部4に供給するものである。   The upper tank 3 secures more than a certain amount of toilet flushing water D by the operation of the water pump 21, provides a flush water supply passage 33 for the flush toilet unit 4, and signals from the flush toilet unit 4 (attached to the toilet bowl) A fixed washing water D is supplied to the flush toilet unit 4 by an operation instruction by a float valve of the water tank).

水洗トイレ部4は、水洗トイレ41と、前記水洗トイレ41にトイレ排水(汚物水)Eの排水個所に圧送ポンプ42を有するトイレ排水Eの圧送構造(例えば圧送ポンプ42を配置する汚物水溜め、汚物水を圧送し易くする粉砕攪拌機構等)を付設しているものである。尚本実施形態は、中水Cを使用する例を示したが、中水Cの供給が十分でない場合や、集水施設の設置が困難な場所では、通常の水道水を洗浄用水として使用することもできる。   The flush toilet unit 4 includes a flush toilet 41, a flush structure of a toilet drain E having a flush pump 42 at a drainage point of toilet drain (sewage water) E in the flush toilet 41 (for example, a waste water reservoir in which the pump pump 42 is disposed, A crushing stirring mechanism or the like that facilitates pumping of waste water is provided. In addition, although this embodiment showed the example which uses the middle water C, when supply of the middle water C is not enough, or the place where installation of a water collection facility is difficult, normal tap water is used as washing water. You can also

水洗トイレ41は、一般的な水洗トイレ構造であるが、特に便器洗浄機構に特別な構造及び制御を採用してなるものである。即ち通常の便器と同様に洗浄水タンク(フロート弁・一定量の供給弁を付設)とトラップ排水構造を備えるが、前記の洗浄水タンクは中水用として使用し、その他に清浄水(水道水や、水道施設が無い場合などは沢の水等を利用する)Fを使用するための構造を付設したものである。   Although the flush toilet 41 has a general flush toilet structure, it employs a special structure and control especially for the toilet flushing mechanism. In other words, it is equipped with a wash water tank (with a float valve and a fixed amount of supply valve) and a trap drainage structure as in a normal toilet, but the wash water tank is used for medium water, and in addition to clean water (tap water) In the case where there is no water supply facility, a structure for using F) is used.

即ちトイレ洗浄に際しては、洗浄水タンク(中水を貯留)から従前の便器洗浄と同様に、レバー操作等で洗浄水タンクから一気に洗浄用水(中水)Dを供給して、便器内の汚物を流し出し、前記洗浄用水Dの供給後に一定量の清浄水Fを便器内に供給する構造を採用する。そうするとトイレ使用後には、便器内に清浄水Fが滞留することになる。勿論局部洗浄装置を付設する場合には、清浄水Fを使用する。   That is, when cleaning the toilet, the cleaning water (medium water) D is supplied from the washing water tank at once by the lever operation etc. from the washing water tank (stores the middle water) in the same manner as the conventional toilet bowl washing, and the waste in the toilet bowl is removed. A structure is adopted in which a certain amount of clean water F is supplied into the toilet after the flushing water D is supplied. Then, the clean water F stays in the toilet after using the toilet. Of course, when a local cleaning device is attached, clean water F is used.

尚清浄水Fを使用するために、清浄水Fの供給が水道水のように相応の圧力を以て行われる場合には、適宜制御される開閉弁を介して便器に供給されるようにし、所定の圧力を伴わず、単に清浄水Fの流れ込みのみを利用する場合には、更に貯水タンクを付設する。   In addition, in order to use the clean water F, when the supply of the clean water F is performed with an appropriate pressure as in the case of tap water, the clean water F is supplied to the toilet through an appropriately controlled on-off valve. In the case where only the flow of clean water F is used without pressure, a water storage tank is additionally provided.

トイレ排水Eに対しては固液分離処理部5を設けている。固液分離処理部5は、図2(イ)に例示するように、胴部が通気性を備えた槽本体51の内部に、スクリーン部52を内設して上方室53と下方室54を形成し、上方室53のスクリーン部52の上部には、枯れ草、粉砕樹皮等の透水性を有し、且つ有機質の生物分解を行う土壌資材で形成した土壌処理層部55を形成し、前記の土壌処理層部55の上或いは中に、トイレ排水Eの放出口を開口したトイレ排水導入部56を付設し、下方室54には、蒸発処理部1への排出部57を設けてなるものである。   For the toilet drainage E, a solid-liquid separation processing unit 5 is provided. As illustrated in FIG. 2 (a), the solid-liquid separation processing unit 5 includes an upper chamber 53 and a lower chamber 54 provided inside a tank body 51 whose body portion is air permeable. Formed on the upper part of the screen part 52 of the upper chamber 53 is formed a soil treatment layer part 55 made of a soil material having water permeability such as dead grass and crushed bark and performing organic biodegradation, A toilet drainage introduction part 56 having an opening for the discharge of the toilet drainage E is provided on or in the soil treatment layer part 55, and a discharge part 57 to the evaporation treatment part 1 is provided in the lower chamber 54. is there.

また上方室53における土壌処理層部55の上方位置に、オーバーフロー部58を設けてなる。   An overflow part 58 is provided at a position above the soil treatment layer part 55 in the upper chamber 53.

前記の固液分離処理部5では、トイレ排水Eが土壌処理層部55に放出されると、トイレ排水Eの固形分が土壌処理層部55に付着し、汚水Aはスクリーン部52を通して下方室54に溜まり、次の蒸発処理部1に排出される。またオーバーフロー部58からの汚水Aも蒸発処理部1に排出される。   In the solid-liquid separation processing unit 5, when the toilet drainage E is discharged to the soil processing layer unit 55, the solid content of the toilet drainage E adheres to the soil processing layer unit 55, and the sewage A passes through the screen unit 52 to the lower chamber. 54 is discharged to the next evaporation processing unit 1. Further, the sewage A from the overflow unit 58 is also discharged to the evaporation processing unit 1.

更に土壌処理層部55で濾されて残った固形分は、土壌処理層部55に生存する生物(例えばミミズ)や微生物(枯れ草、粉砕樹皮等に付着している細菌)によって分解処理される。   Further, the solid content remaining after being filtered by the soil treatment layer portion 55 is decomposed by living organisms (for example, earthworms) and microorganisms (bacteria attached to dead grass, crushed bark, etc.) that live in the soil treatment layer portion 55.

前記の固液分離処理部5は、固形分を土壌処理層部55で濾過させる土壌放出処理構造の例であるが、図2(ロ)に示すように液槽放出処理構造でも良い。図2(ロ)に示した固液分離処理部5aは、槽本体51aの内部に、スクリーン部52aを内設して上方室53aと下方室54aを形成し、上方室53aのスクリーン部52aの上部には、適宜な土壌資材で形成した土壌処理層部55aを形成し、下方室54aを汚水だめとして汚水処理層部58aとしたものである。尚固液分離処理部5aにおいても、槽本体51aの上方部分にオーバーフロー部を設けて、蒸発処理部1に排出するようにしても良い。   The solid-liquid separation processing unit 5 is an example of a soil discharge processing structure in which solid content is filtered by the soil processing layer unit 55, but may be a liquid tank discharge processing structure as shown in FIG. The solid-liquid separation processing unit 5a shown in FIG. 2 (b) has an upper chamber 53a and a lower chamber 54a provided inside the tank body 51a to form an upper chamber 53a and a lower chamber 54a. In the upper part, a soil treatment layer portion 55a made of an appropriate soil material is formed, and the sewage treatment layer portion 58a is formed by using the lower chamber 54a as a sewage reservoir. In the solid-liquid separation processing unit 5a, an overflow unit may be provided in the upper part of the tank body 51a and discharged to the evaporation processing unit 1.

この下方室54aの上方部分に放出口を開口したトイレ排水導入部56aを付設し、下方室の中間に蒸発処理部1への排出部57aを設けてなるものである。   A toilet drainage introduction part 56a having an opening is provided in the upper part of the lower chamber 54a, and a discharge part 57a to the evaporation processing part 1 is provided in the middle of the lower chamber.

前記の固液分離処理部5aは、下方室54aにトイレ排水Eが放出され滞留すると、嫌気菌による嫌気処理が為されて、少量の沈殿物と上層のスカムGに分離し、中間の汚水Aは蒸発処理部1に排出され、スカムGは、トイレ排水Eの流入時に下方室54aの水位が上昇することによって、スクリーン部52aに付着し、土壌処理層部55aの微生物によって分解処理される。   When the toilet drainage E is discharged and stays in the lower chamber 54a, the solid-liquid separation processing unit 5a is subjected to anaerobic treatment by anaerobic bacteria, and is separated into a small amount of sediment and upper scum G, and the intermediate sewage A The scum G adheres to the screen portion 52a when the water level in the lower chamber 54a rises when the toilet drainage E flows in, and is decomposed by microorganisms in the soil treatment layer portion 55a.

勿論固液分離処理部5,5aは、前記の構成に特定されるものではなく、固液分離と生物分解処理が為されるものであれば良いので、従前周知の曝気槽を採用すると共に、曝気槽からの放流を蒸発処理部1に送るようにしても良い。   Of course, the solid-liquid separation processing units 5 and 5a are not limited to the above-described configuration, and any solid-liquid separation and biodegradation treatment may be performed. The discharge from the aeration tank may be sent to the evaporation processing unit 1.

而して前記のトイレ装置は、雨水Cを下方タンク2に溜め、上方タンク3に送水してトイレ洗浄用水Dとして溜めて、水洗トイレ41を使用すると、トイレ洗浄用水Dを供給してトイレ洗浄を行う。   Thus, the toilet device collects rainwater C in the lower tank 2, feeds it into the upper tank 3 and stores it as toilet cleaning water D, and when the flush toilet 41 is used, the toilet cleaning water D is supplied to wash the toilet. I do.

トイレ洗浄後のトイレ排水Eは、固液分離処理部5に送られ、固液分離と共に、生物分解処理が為され、固液分離処理部5からの汚水Aは、蒸発処理部1に送られる。   The toilet waste water E after the toilet cleaning is sent to the solid-liquid separation processing unit 5, biodegradation processing is performed along with the solid-liquid separation, and the sewage A from the solid-liquid separation processing unit 5 is sent to the evaporation processing unit 1. .

蒸発処理部1では、その重力浸透で通水分解処理部12と蒸発分解処理部13において、生物分解処理が行われると共に蒸発分解処理部13においては、更に継続的に蒸発が行われ、多段階の生物処理と吸着処理と蒸発処理によって原則的に無排水処理が行われる。仮に余剰水Bが生じたとしても、ある程度浄化されており、下方タンクに送られるが、再度循環させて蒸発処理を行っても良いし、中水Cと混合して洗浄用水Dとして使用されたり、植物灌漑用として使用される。   In the evaporation processing unit 1, the water penetration decomposition processing unit 12 and the evaporation decomposition processing unit 13 perform biodegradation processing by gravity permeation, and the evaporation decomposition processing unit 13 further performs evaporation to perform multistage. In principle, no wastewater treatment is performed by biological treatment, adsorption treatment and evaporation treatment. Even if surplus water B is generated, it is purified to some extent and sent to the lower tank. However, it may be circulated again to perform the evaporation treatment, or mixed with the intermediate water C to be used as cleaning water D. Used for plant irrigation.

しかも前記の各設備は、土中設置設備を必要とせず、全て地上に容易に構築することができるので、設置場所の限定が無く、更に安価に設置できるものである。   In addition, since each of the above-mentioned facilities does not require an installation facility in the ground and can be easily constructed on the ground, the installation location is not limited and can be installed at a lower cost.

このように簡易に地上設置が可能であるから、例えば蒸発処理部を適宜な室(ビニールハウス等)に収納し、適宜な廃熱利用によって冬季においても、生物分解処理や蒸発処理を適切に行うこともできる。   Since it can be easily installed on the ground in this way, for example, the evaporation processing unit is stored in an appropriate room (such as a plastic house), and biodegradation processing and evaporation processing are appropriately performed even in winter by using appropriate waste heat. You can also

また特に前記のポンプ作動及びその制御動作の動力源として、太陽電池及びその蓄電機構でまかなうと、水道設備や電力供給設備が無い山小屋等のトイレ設置にも最適なものとなる。   In particular, when the solar cell and its power storage mechanism are used as a power source for the pump operation and its control operation, it is also optimal for toilet installation in a mountain hut or the like without water supply facilities or power supply facilities.
