Description

本発明は、複数積み重ねて用いる汚水浄化用の微生物担持単体及びこれを用いた汚水浄化装置に関する。   The present invention relates to a microorganism-supporting single substance for purifying sewage used by stacking a plurality thereof and a sewage purifying apparatus using the same.

生活廃水や産業廃水は、汚水処理槽において含有されている汚染物質を微生物により分解処理し、浄化してから一般下水として排出することが多い。
そして、微生物濃度を高めて処理速度を増大させるために、汚水処理槽内に設置される微生物担体を備えた汚水浄化装置が種々提案されている。
微生物担体としては、網状固定化担体、ひも状固定化担体、ハニカム状担体、回転円板、波板担体、平板担体等の非流動型担体や、スポンジ状担体或いは繊維状担体等の流動型担体が知られている（特許文献１）。 Domestic wastewater and industrial wastewater are often discharged as general sewage after decomposing and purifying the pollutants contained in the sewage treatment tank with microorganisms.
In order to increase the concentration of microorganisms and increase the treatment speed, various sewage purification apparatuses including a microbial carrier installed in a sewage treatment tank have been proposed.
Examples of the microorganism carrier include non-flow type carriers such as a net-like immobilization carrier, a string-like immobilization carrier, a honeycomb carrier, a rotating disk, a corrugated plate carrier, and a flat plate carrier, and a fluid type carrier such as a sponge carrier or a fibrous carrier. Is known (Patent Document 1).

しかし、流動型担体は汚水処理槽から流出したり、底に沈殿する虞があり、流出予防のスクリーン等を汚水処理槽の上部に設置しなければならなかった。
また、非流動型担体は、汚水処理槽の規模や形状に応じて大きさや形を変えなければならず、網状やヒモ状のように不定形のものは、適当な位置に設置するための特別な装置が必要となる。さらに、１個の分解不能な担体では、微生物が剥離したり破損した場合に、担体全体を交換しなければならなかった。 However, there is a possibility that the fluid type carrier flows out of the sewage treatment tank or settles at the bottom, and a screen for preventing spillage or the like has to be installed on the upper part of the sewage treatment tank.
In addition, the non-flowable carrier must be changed in size and shape according to the size and shape of the sewage treatment tank, and the non-flowable carrier such as a mesh or string is specially designed for installation at an appropriate position. Equipment is required. In addition, with one non-degradable carrier, the entire carrier had to be replaced when the microorganisms were detached or damaged.

特開平８−１９７０７８号公報Japanese Patent Application Laid-Open No. 8-97078

本発明が解決しようとする課題は、構造が簡単で容易に組み立てることができ、設置個所に応じて形や大きさを自由に変更することが可能で、個別の微生物担持単体の交換もできる汚水浄化用の微生物担持単体及び汚水浄化装置を提供することにある。   The problem to be solved by the present invention is that the structure is simple and can be assembled easily, the shape and size can be freely changed according to the installation location, and the individual microorganism-supporting single substance can be replaced. An object of the present invention is to provide a microorganism supporting single body and a sewage purification apparatus for purification.

本発明の汚水浄化用の微生物担持単体は、セラミックを素材とし、板体の表面に連結凹部を形成すると共に、裏面に連結突起を設け、該連結突起を前記連結凹部へ挿入可能な形状とし、前記連結突起の基部に前記連結凹部よりも径大の鍔部を形成し、外面に汚染物質分解微生物を付着させてある。
また、本発明の汚水浄化装置は、この微生物担持単体を前記連結突起を前記連結凹部へ挿入することにより、前記板体間に隙間をあけて複数積み重ねて成る。 The microorganism-supporting single substance for purifying sewage according to the present invention is made of ceramic, has a connection recess on the surface of the plate, has a connection protrusion on the back surface, and has a shape that allows the connection protrusion to be inserted into the connection recess. A flange having a diameter larger than that of the connection recess is formed at the base of the connection protrusion, and contaminant-degrading microorganisms are attached to the outer surface.
In the sewage purification apparatus of the present invention, a plurality of the microorganism-supporting single bodies are stacked with a gap between the plates by inserting the connection protrusions into the connection recesses.

微生物担持単体は、前記板体の外周縁の３箇所以上に、連結ロッド係合切欠を等間隔で形成しても良い。
この微生物担持単体を用いた汚水浄化装置は、微生物担持単体を、前記連結突起を前記連結凹部へ挿入することにより、前記板体間に隙間をあけて複数積み重ねて成る柱状体を複数本並べ、これら柱状体の両端に一対の挟持板を配置し、各柱状体ごとに前記微生物担持単体の連結ロッド係合切欠を一致させると共に、この連結ロッド係合切欠に連結ロッドを通し、該連結ロッドの両端を前記挟持板に止めつけてある。 The microorganism-supporting single body may be formed with connecting rod engagement notches at equal intervals at three or more positions on the outer peripheral edge of the plate.
In the sewage purification apparatus using this microorganism-supported simple substance, by inserting the connection protrusion into the connection recess, the microorganism-supported simple substance is arranged in a plurality of columnar bodies with a plurality of stacked gaps between the plates, A pair of clamping plates are arranged at both ends of these columnar bodies, and the connecting rod engaging cutouts of the microorganism-supporting single body are made to coincide with each columnar body, and the connecting rods are passed through the connecting rod engaging cutouts. Both ends are fixed to the holding plate.

本発明の微生物担持単体は、セラミックを素材としているので水中にあっても腐食する虞が無く、構造が簡単で大量生産が可能なためコストが低廉で済み、別体の接合具等を用いずに、板体間に隙間をあけた状態で簡単に積み重ねることができる。
また、予め、汚染物質分解微生物を付着させてあるので、発生するまで１週間から数ヶ月を要する自然の有効菌を利用するものに比べて即効性が高い。 Since the microorganism-supporting simple substance of the present invention is made of ceramic, there is no risk of corrosion even in water, the structure is simple and mass production is possible, and the cost is low. In addition, it can be easily stacked with a gap between the plates.
In addition, since pollutant-degrading microorganisms are attached in advance, it has a higher immediate effect than those using natural effective bacteria that require one week to several months to occur.

本発明の汚水浄化装置は、微生物担持単体が発揮する効果に加えて、組み立てが容易であり、複数の微生物担持単体を積み重ねてあるので、微生物担持単体の数や組み合わせ形態を変えて設置場所の規模に対応することが可能であるばかりか、微生物による被覆が剥がれたり、破損した微生物担持単体を容易に交換することができる。
また、板体の外周縁に３個以上の連結ロッド係合切欠を形成し、汚水浄化装置を組み立てる際に、この連結ロッド係合切欠に連結ロッドを通して挟持板に止めつければ、積み重ねた微生物担持単体が側方に移動するのを規制するので、柱状体を安定して支持することができる。 The sewage purification apparatus of the present invention is easy to assemble in addition to the effects exhibited by the microorganism-supporting single substance, and a plurality of microorganism-supporting single-elements are stacked. In addition to being able to cope with the scale, it is possible to easily replace a microorganism-supported single body that has been peeled off or damaged by a microorganism.
In addition, when three or more connecting rod engaging notches are formed on the outer peripheral edge of the plate body and the sewage purification apparatus is assembled, if the connecting rod engaging notches are passed through the connecting rods and fastened to the holding plate, the accumulated microorganisms are supported. Since the single body is restricted from moving sideways, the columnar body can be stably supported.

以下、本発明の実施例を図面に基づいて詳細に説明する。
図１〜図３に示すように、汚水浄化装置に用いる微生物担持単体１は、セラミックを素材とし、板体２の表面に連結凹部３を設けると共に、裏面に連結突起４を一体に設け、外面に汚染物質分解微生物を付着して成る。
板体２は、直径４０ｍｍ、厚さ７ｍｍ程度の円板であり、微生物付着面積を増やすために、外面に放射状溝５等の凹凸を形成してある。
また、板体２の外周縁には４個の連結ロッド係合切欠６が形成される。連結ロッド係合切欠６は平面視で直径４ｍｍ程度の半円であり、周方向に等間隔で配置される。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 to 3, the microorganism-supporting single unit 1 used in the sewage purification apparatus is made of ceramic, provided with a connecting recess 3 on the surface of the plate body 2, and integrally provided with a connecting protrusion 4 on the back surface. It consists of adhering pollutant-degrading microorganisms.
The plate body 2 is a disc having a diameter of about 40 mm and a thickness of about 7 mm, and irregularities such as radial grooves 5 are formed on the outer surface in order to increase the area to which microorganisms adhere.
Further, four connecting rod engaging notches 6 are formed on the outer peripheral edge of the plate body 2. The connecting rod engagement notches 6 are semicircles having a diameter of about 4 mm in plan view, and are arranged at equal intervals in the circumferential direction.

連結凹部３は板体２の表面中心部に設けられ、底部に近づくに従って次第に径が小さくなる断面円形のテーパー穴であり、最大径１２ｍｍ、深さ１５ｍｍ程度とする。
連結突起４は板体２の裏面中心部に設けられ、その基部に鍔部７が形成される。連結突起４は先端に向かって次第に細くなっている断面円形の棒状を成し、先端部の直径が４ｍｍ、長さが１０ｍｍとしてある。即ち、連結突起４は連結凹部３へ挿入可能な形状・寸法となっている。
鍔部７は、先端に向かって次第に径が小さくなる円錐台形に形成され、先端面の直径は連結凹部３の最大直径よりも大きい１５ｍｍ程度としてある。また、鍔部７の高さは約１０ｍｍとする。 The connecting recess 3 is a tapered hole having a circular cross section that is provided in the center of the surface of the plate 2 and gradually decreases in diameter as it approaches the bottom, and has a maximum diameter of 12 mm and a depth of about 15 mm.
The connection protrusion 4 is provided at the center of the back surface of the plate body 2, and a flange 7 is formed at the base thereof. The connecting protrusion 4 has a bar shape with a circular cross section that gradually becomes thinner toward the tip, and the tip has a diameter of 4 mm and a length of 10 mm. That is, the connecting projection 4 has a shape and size that can be inserted into the connecting recess 3.
The flange portion 7 is formed in a truncated cone shape whose diameter gradually decreases toward the tip, and the diameter of the tip surface is about 15 mm, which is larger than the maximum diameter of the connecting recess 3. Moreover, the height of the collar part 7 shall be about 10 mm.

微生物は膜状に付着して微細な窪みの内部には付着しないので、微生物担持単体１の外面に細かくて深い凹凸を形成したり、内部に細かい空隙を形成することは意味が無いばかりか、加工に手間がかかってコストを引き上げる要因となる。
また、微生物担持単体１の外面に細かい凹凸を形成せず平滑に仕上げると、細菌膜で厚く覆われていても簡単に剥がすことができて、清掃しやすい。 Since microorganisms adhere to the film and do not adhere to the inside of the fine depression, it is not meaningful to form fine and deep irregularities on the outer surface of the microorganism-supporting single body 1 or to form fine voids inside. It takes time and effort to increase the cost.
Also, if the outer surface of the microorganism-supporting single body 1 is finished smoothly without forming fine irregularities, it can be easily removed even if it is thickly covered with a bacterial film and is easy to clean.

汚染物質を分解微する生物を付着させるには、微生物の培養液に未処理の微生物担持単体１を浸し、短時間で引き上げて乾燥させる。
微生物の培養液としては、塩素処理を施していない水（例えば井戸水）２００リットルに対して糖蜜３０リットルを溶かして培地とし、この中に市販されている微生物（ＥＭ菌等）の原液２リットルを投入して、循環ポンプで軽く攪拌しながら４０℃で１週間培養し、さらに塩素処理していない水（例えば井戸水）で１０倍に希釈したものを用いる。
実際に市販する場合には、このように微生物を付着させて乾燥した微生物担持単体１をパックし、輸送及び販売することができる。 In order to attach a living organism that decomposes and decontaminates the pollutant, the untreated microorganism-supporting simple substance 1 is immersed in a culture solution of microorganisms, and is pulled up and dried in a short time.
As a culture solution for microorganisms, 30 liters of molasses is dissolved in 200 liters of chlorinated water (for example, well water) to form a culture medium. It is added and cultured at 40 ° C. for 1 week with light agitation with a circulation pump, and further diluted 10 times with water that has not been chlorinated (for example, well water).
In the case of actually putting it on the market, it is possible to pack the microorganism-supporting simple substance 1 dried by attaching microorganisms in this way, and to transport and sell it.

微生物担持単体１を用いた汚水浄化装置は、図４に示すように、複数の微生物担持単体１を積み重ねて成る柱状体８を複数本並べて形成される。
図５に示すように、柱状体８を構成する微生物担持単体１は、連結突起４を裏面側に隣接する微生物担持単体１の連結凹部３へ挿入することにより、多数段に積み重ねられる。
連結突起４を連結凹部３へ挿入すると、連結突起４の基部に形成された鍔部７が隣接する微生物担持単体１の表面に当接するので、微生物担持単体１の板体２間にはそれぞれ鍔部７の高さに相当する隙間が形成される。 As shown in FIG. 4, the sewage purification apparatus using the microorganism-supported single body 1 is formed by arranging a plurality of columnar bodies 8 formed by stacking a plurality of microorganism-supported single bodies 1.
As shown in FIG. 5, the microorganism-supporting single bodies 1 constituting the columnar body 8 are stacked in multiple stages by inserting the connection protrusions 4 into the connection recesses 3 of the microorganism-supporting single bodies 1 adjacent to the back surface side.
When the connecting protrusion 4 is inserted into the connecting recess 3, the flange 7 formed at the base of the connecting protrusion 4 comes into contact with the surface of the adjacent microorganism-supporting single body 1. A gap corresponding to the height of the portion 7 is formed.

図４に示すように、縦横に並べた柱状体８の両端には一対の挟持板９，１０を配置し、挟持板９，１０の四隅部には、挟持板９，１０どうしを連結する支柱１１が設置される。
また、各柱状体８ごとに、積み重ねた微生物担持単体１の連結ロッド係合切欠６を一致させると共に、この連結ロッド係合切欠６に連結ロッド１２を通し、連結ロッド１２の両端を挟持板９，１０に止めつけてある。
なお、微生物担持単体１の裏面側に位置する挟持板９には、柱状体８の設置個所の中央に、連結突起４を係合するための孔を形成してある。
また、挟持板９，１０、支柱１１及び連結ロッド１２は、水中でも腐食し難いアクリル樹脂等の合成樹脂を素材とするのが望ましい。
支柱１２及び連結ロッド１２を挟持板９，１０に止めつけるには、直接ねじ込んだり、クリップ等の適宜止め具を用いる。 As shown in FIG. 4, a pair of sandwiching plates 9, 10 are arranged at both ends of a columnar body 8 arranged vertically and horizontally, and pillars that connect the sandwiching plates 9, 10 at the four corners of the sandwiching plates 9, 10. 11 is installed.
Further, for each columnar body 8, the connecting rod engaging notches 6 of the stacked microorganism-supporting single bodies 1 are made to coincide with each other, the connecting rod 12 is passed through the connecting rod engaging notches 6, and both ends of the connecting rod 12 are sandwiched between the holding plates 9. , 10.
Note that a hole for engaging the connection protrusion 4 is formed in the center of the installation place of the columnar body 8 in the holding plate 9 located on the back side of the microorganism-supporting single body 1.
Further, it is desirable that the sandwiching plates 9 and 10, the support column 11 and the connecting rod 12 are made of a synthetic resin such as an acrylic resin that hardly corrodes in water.
In order to fasten the support column 12 and the connecting rod 12 to the sandwiching plates 9 and 10, they are directly screwed in or an appropriate stopper such as a clip is used.

汚水浄化装置を組み立てるには、挟持板９に柱状体８設置個所を取り巻くように連結ロッド１２を起立させておき、連結ロッド１２で囲まれた空間に微生物が付着された微生物担持単体１を、連結ロッド係合切欠６と連結ロッド１２とを係合させながら順次落とし込み、下段の微生物担持単体１の連結凹部３へ上段の微生物担持単体１の連結突起４を差し込んで積み重ねる。
所定数の微生物担持単体１が積み重なって柱状体８が形成されたら、挟持板９の四隅部に支柱１１を立設させ、連結ロッド１２、柱状体８及び支柱１１の上方から挟持板１０を被せ、連結ロッド１２及び支柱１１の端部を挟持板１０に止めつけて、挟持板９，１０により柱状体８を挟持する。 In order to assemble the sewage purification apparatus, the connecting rod 12 is erected on the sandwiching plate 9 so as to surround the place where the columnar body 8 is installed, and the microorganism-supporting single body 1 in which microorganisms adhere to the space surrounded by the connecting rod 12, The connecting rod engaging notch 6 and the connecting rod 12 are sequentially dropped while being engaged, and the connecting projection 4 of the upper microorganism-supporting single body 1 is inserted into the connecting recess 3 of the lower microorganism-supporting single body 1 and stacked.
When the columnar body 8 is formed by stacking a predetermined number of the microorganism-supporting single bodies 1, the columns 11 are erected at the four corners of the clamping plate 9, and the coupling plate 12, the columnar body 8, and the clamping plate 10 are covered from above the columns 11. Then, the end portions of the connecting rod 12 and the support column 11 are fixed to the holding plate 10, and the columnar body 8 is held by the holding plates 9 and 10.

組み立てた汚水浄化装置は、一般的な曝気式浄化槽等に沈めて使用する。すると、板体２間に形成された隙間が水の流路となって、汚水が広面積の微生物付着面に接触する。
なお、設置する槽の大きさに応じて、積み重ねる微生物担持単体１の数、及び、並べる柱状体８の数は適宜変更することができる。
また、排水路のような細長い場所に設置する場合には、多数の微生物担持単体１を積み重ねた１本の柱状体８によって汚水浄化装置を構成することもできる。 The assembled sewage purification apparatus is used by being submerged in a general aeration septic tank. Then, the clearance gap formed between the board | plate bodies 2 becomes a flow path of water, and sewage contacts the microorganisms adhesion surface of a large area.
In addition, according to the magnitude | size of the tank to install, the number of the microbe carrying | support single bodies 1 to pile up and the number of the columnar bodies 8 to arrange can be changed suitably.
Moreover, when installing in the elongate place like a drainage channel, a sewage purification apparatus can also be comprised by the one columnar body 8 which piled up many microorganisms single-piece | unit 1.

微生物担持単体１の大きさ及び各部の形状は上記実施例に限定されない。例えば、板体２の平面形状を角形としたり、連結凹部３、連結突起４及び鍔部７の断面形状を角形とすることもできる。
また、板体２の外周縁に形成した連結ロッド係合切欠６の数は、係合した連結ロッド１２が積み重ねた微生物担持単体を安定して支持できる数であれば良く、３個或いは５個以上とすることも可能である。 The size of the microorganism-supporting single body 1 and the shape of each part are not limited to the above embodiment. For example, the planar shape of the plate body 2 can be a square, and the cross-sectional shapes of the connecting recess 3, the connecting protrusion 4, and the flange 7 can be a square.
Further, the number of connecting rod engaging notches 6 formed on the outer peripheral edge of the plate body 2 may be any number as long as the engaged connecting rods 12 can stably support the stacked microorganism-supporting single bodies. The above is also possible.

さらに、汚染物質分解微生物の有効性は地域によって異なり、例えば、ＥＭ菌は仙台以北では有効に機能しない。従って、微生物担持単体１をすでにその地域で機能している浄化槽へ短時間浸漬した後に乾燥させたり、或いは、機能している浄化槽内の汚染物質分解微生物や液体を培養して浸漬後乾燥させることにより、微生物担持単体１へ汚染物質分解微生物を付着させることもできる。
もちろん、汚水浄化装置を組み立ててから、汚染物質分解微生物を付着させることも可能である。 In addition, the effectiveness of pollutant-degrading microorganisms varies from region to region, for example, EM bacteria do not function effectively beyond Sendai. Therefore, the microorganism-supporting single substance 1 is dipped in a septic tank already functioning in the region for a short time and then dried, or the microorganisms and liquids that decompose pollutants in the functioning septic tank are cultured and dried after dipping. Thus, the pollutant-decomposing microorganisms can be attached to the microorganism-supporting single substance 1.
Of course, it is also possible to attach pollutant-decomposing microorganisms after assembling the sewage purification apparatus.
