Description

本発明は、主として降雨時に発生する非点汚染源を除去する装置に係り、より詳しくは、道路、駐車場、商店街、住宅団地、産業団地などの地域で降雨により発生する浮遊物質、土砂などの汚染物質が、雨汚水管路を介して川または湖沼などに直接放流されることを防止し、浮遊または溶存している汚染物質を沈殿および吸着濾過手段により効果的に除去することができる非点汚染源除去装置に関するものである。   The present invention relates to an apparatus for removing a non-point pollution source mainly generated during rain, and more specifically, suspended matter generated by rain in areas such as roads, parking lots, shopping streets, housing complexes, industrial parks, earth and sand, etc. Contaminants can be prevented from being directly discharged into rivers or lakes through rainwater drainage pipes, and suspended or dissolved pollutants can be effectively removed by precipitation and adsorption filtration means The present invention relates to a pollution source removing apparatus.

非点汚染源は、特定の排出経路を通じて発生せずに不特定の排出経路を通じて発生する汚染物質であって、主に降雨時に地表面流出水とともに流出されて川などに流入して水質に悪影響を及ぼす。   Non-point pollution sources are pollutants that are not generated through specific discharge routes, but are generated through unspecified discharge routes, and are mainly discharged along with ground surface runoff during rainfall and flow into rivers, etc., and have an adverse effect on water quality. Effect.

降雨により発生した非点汚染源を除去するために使用されている従来の方法としては、貯留型（貯留槽、池、人工湿地など）、浸透型（浸透槽、浸透溝など）、植生型（植生濾過帯、植生水路など）、装置型（ストームフィルタ、サンドフィルタ、ストームゲートなど）などがある。   Conventional methods used to remove non-point pollution sources caused by rainfall include storage types (storage tanks, ponds, constructed wetlands, etc.), infiltration types (infiltration tanks, infiltration grooves, etc.), vegetation types (vegetation) Filter zones, vegetation canals, etc.) and device types (storm filters, sand filters, storm gates, etc.).

このような従来の非点汚染源除去装置は、初期降雨後の汚染物質が殆どない雨水も処理しなければならないため、非効率的であり、全体降雨量を処理しなければならないため、設備施設が無駄に大きくなるといった問題点を有する。   Such a conventional non-point source removal apparatus is also inefficient because it must process rainwater that is almost free of pollutants after the initial rainfall, and it must handle the entire rainfall. There is a problem that it becomes uselessly large.

すなわち、道路、駐車場、商店街、住宅団地、産業団地などで降雨により発生する非点汚染源の殆どは、６〜１５ｍｍ、より詳しくは１０ｍｍの初期降雨に含まれている。しかし、前述したような施設は、この事実とは無関係に、該当地域の降雨記録資料および土地利用計画などの資料に基づき、発生降雨の全量を処理するように設計されているため、施設の過大と処理効率の低下に帰結される問題点を抱えている。   That is, most of the non-point pollution sources generated by rainfall in roads, parking lots, shopping streets, residential complexes, industrial parks, etc. are included in the initial rainfall of 6 to 15 mm, more specifically 10 mm. However, regardless of this fact, facilities such as those mentioned above are designed to handle the total amount of generated rainfall based on the rainfall record data and land use plans of the area, so there is an excess of facilities. And have problems that result in a reduction in processing efficiency.

従来の非点汚染源処理施設の設計例を挙げると、降雨再現期間が１０年、持続時間が１時間であるとき、降雨強度はおよそ６８ｍｍ／ｈｒであって、初期降雨１０ｍｍの６．８倍に相当する降雨強度に合う処理施設が設計されている。   As a design example of a conventional non-point pollution source treatment facility, when the rainfall reproduction period is 10 years and the duration is 1 hour, the rainfall intensity is about 68 mm / hr, which is 6.8 times the initial rainfall of 10 mm. Treatment facilities are designed to meet the corresponding rainfall intensity.

そのほかの既存の処理施設の問題点は次のようである。   Other problems with existing treatment facilities are as follows.

貯留型の場合は、比較的大規模の土地が必要であるため、既に開発された地域などには地価の上昇で設置が難しく、夏季には蚊、蝿などの害虫が発生するため、保健上の問題点を誘発する。   In the case of the storage type, relatively large-scale land is required, so it is difficult to install it in areas that have already been developed due to rising land prices. In summer, pests such as mosquitoes and moths are generated. Trigger the problem.

浸透型は、土砂、浮遊物、および汚染物の持続的な流入により空隙が詰まるため、処理効率が低下するなど、維持管理が難しく、地下に浸透されるため、地下水の汚染可能性が高い。   The permeation type is clogged due to the continuous inflow of earth and sand, suspended solids, and contaminants, so that it is difficult to maintain, such as a reduction in treatment efficiency, and it penetrates underground, so there is a high possibility of groundwater contamination.

植生型は、一定規模以上の土地が必要となり、植生が維持できる理想的環境条件が必要である。   The vegetation type requires land of a certain scale and ideal environmental conditions that can maintain vegetation.

装置型は、浮遊物質を一定分除去することはできるが、溶存性汚染物質、または重金属のような汚染物質を殆ど除去することができないなどの問題点を持っている。   The apparatus type has a problem that suspended substances can be removed by a certain amount, but dissolved contaminants or contaminants such as heavy metals can hardly be removed.

特に、現代社会の急激な都市、道路、工場などの開発および発達により発生する多種多様な汚染物質が地表面または浅い地中に累積していて、雨天時に川または湖沼などに直接流入して、水生植物が斃死し、上水源汚染が深刻化しているが、これに対する効率的な対策がない状態である。   In particular, a wide variety of pollutants generated by the rapid development and development of modern cities, roads, factories, etc., accumulate on the ground surface or shallow ground, and flow directly into rivers or lakes during rainy weather. Aquatic plants have drowned and water pollution has become more serious, but there are no effective countermeasures.

本発明者らは非点汚染源を効率よく除去するため、初期降雨６〜１５ｍｍ、好ましくは１０ｍｍを採集し、沈殿による汚染物質の分離と、吸着濾過手段による溶存性汚染物質、重金属などの除去を可能にする装置を開発した。   In order to efficiently remove non-point contamination sources, the present inventors collect initial rainfall of 6 to 15 mm, preferably 10 mm, and separate contaminants by precipitation and removal of dissolved contaminants, heavy metals, etc. by adsorption filtration means. Developed a device that enables it.

したがって、本発明は前記のような従来の問題点を補完、改善するためになされたもので、初期降雨６〜１５ｍｍ、好ましくは１０ｍｍに対する効率的な処理容量を有し、沈殿による汚染物質の分離と、吸着濾過手段による溶存性汚染物質、重金属などの除去を可能にすることにより、非点汚染源を効果的に処理し、処理施設をコンパクトにする装置を提供することにある。   Therefore, the present invention has been made to supplement and improve the conventional problems as described above, and has an effective treatment capacity for initial rainfall of 6 to 15 mm, preferably 10 mm, and separation of pollutants by precipitation. It is another object of the present invention to provide a device that effectively treats non-point contamination sources and makes the treatment facility compact by enabling removal of dissolved contaminants, heavy metals, and the like by an adsorption filtration means.

また、本発明は、初期降雨を多段階の浄化過程により川または湖沼に放流させることにより、水質汚染を減らすことができる非点汚染源除去装置を提供することにある。   It is another object of the present invention to provide an astigmatism source removing device capable of reducing water pollution by discharging initial rainfall to a river or lake through a multi-step purification process.

上記課題を解決するために、本発明は、雨汚水が流入される流入口と流入雨汚水を越流させる越流ゲートが形成された流入待機室と、前記流入待機室に連通した第１流入口と、第１流出口とを有し、前記第１流入口および前記第１流出口にそれぞれ設けられた第１流入隔板と第１流出隔板を含む１次沈殿室と、前記１次沈殿室の第１流出口に連通され、第２流出口と、前記第２流出口に設けられた第２流出隔板とを含む２次沈殿室と、前記２次沈殿室の前記第２流出口に連通され、放流水が留まる放流待機室と、前記２次沈殿室に設けられ、浮遊物質、溶存性汚染物質および重金属のような汚染物を吸着除去する濾過手段を含んでなり、初期降雨６〜１５ｍｍに含まれた汚染源を処理するための容量を有することを特徴とする、非点汚染源除去装置を提供する。   In order to solve the above problems, the present invention provides an inflow standby chamber in which an inflow port into which rain sewage flows and an overflow gate for overflowing the inflow rain sewage are formed, and a first flow communicating with the inflow standby chamber. A primary settling chamber having an inlet and a first outlet and including a first inlet and a first outlet provided in the first inlet and the first outlet, respectively, and the primary A secondary precipitation chamber communicating with the first outlet of the settling chamber and including a second outlet and a second outlet plate provided at the second outlet; and the second flow of the secondary settling chamber An initial standby rainfall which is connected to the outlet and has a discharge standby chamber in which the discharged water stays, and a filtration means provided in the secondary sedimentation chamber for adsorbing and removing contaminants such as suspended solids, dissolved pollutants and heavy metals. Astigmatism source removal, characterized in that it has a capacity for treating contamination sources contained in 6-15 mm To provide a device.

以上のように、本発明の非点汚染源除去装置は、初期降雨６〜１５ｍｍ、好ましくは１０ｍｍを採集して、沈殿により汚染物質を分離し、吸着濾過手段による溶存性汚染物質、重金属などを除去することにより、非点汚染源を効果的に処理することができるもので、非点汚染源による川または湖沼の汚染を大きく減少させることができる。   As described above, the astigmatism source removing apparatus of the present invention collects initial rainfall of 6 to 15 mm, preferably 10 mm, separates contaminants by precipitation, and removes dissolved contaminants, heavy metals, etc. by adsorption filtration means. By doing so, the non-point pollution source can be effectively treated, and the pollution of the river or lake by the non-point pollution source can be greatly reduced.

特に、本発明は、既存の処理装置が降雨の全量を流入して処理する方式を採択するため処理施設が過大となる問題点と、初期降雨以後の汚染物質の殆どなお雨水も処理しなければならない非効率性を一緒に解決することができる、経済的な非点汚染源処理装置である。   In particular, the present invention adopts a method in which the existing treatment apparatus inflows and treats the entire amount of rainfall, and there is a problem that the treatment facility becomes excessive, and it is necessary to treat the rainwater which is almost pollutant after the initial rainfall. It is an economical astigmatism source treatment device that can solve the inefficiency that must be avoided.

以下、添付図面を参照しながら本発明の好適な実施形態による非点汚染源除去装置について詳細に説明する。   Hereinafter, an astigmatism source removing apparatus according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

A primary sedimentation chamber 20 is provided, and a first inlet 21 of the primary sedimentation chamber is formed between the inflow standby chamber 10 and the primary sedimentation chamber 20, so that the rain collected in the inflow standby chamber Sewage flows into the primary sedimentation chamber 20 through the first inlet 21 of the primary sedimentation chamber.

また、１次沈殿室の第１流入隔板２５が前記１次沈殿室の第１流入口２１の内側で前方を遮るとともに底面側が開放された状態で１次沈殿室の内壁に離隔して装着されている。   In addition, the first inflow partition plate 25 of the primary sedimentation chamber blocks the front inside the first inlet 21 of the primary sedimentation chamber and is spaced apart from the inner wall of the primary sedimentation chamber with the bottom side open.

図２および図４に示すように、前記１次沈殿室２０との並列の位置には、前記１次沈殿室で沈殿、分離されていない汚染物質を沈殿、除去する２次沈殿室３０が設けられる。   As shown in FIGS. 2 and 4, a secondary sedimentation chamber 30 is provided at a position parallel to the primary sedimentation chamber 20 to precipitate and remove contaminants that have not settled or separated in the primary sedimentation chamber. It is done.

前記１次沈殿室と前記２次沈殿室との間には１次沈殿室の第１流出口２３が形成されるので、１次沈殿室で処理された処理水が前記１次沈殿室の第１流出口２３を介して２次沈殿室３０に流入することもでき、図３に示すように、前記１次沈殿室の第１流出隔板２７が前記１次沈殿室の内側で第１流出口２３の前方を遮るとともに底面側が開放された状態で１次沈殿室の内壁に離隔して装着されている。   Since the first outlet 23 of the primary sedimentation chamber is formed between the primary sedimentation chamber and the secondary sedimentation chamber, the treated water treated in the primary sedimentation chamber is the first sedimentation chamber in the primary sedimentation chamber. It is also possible to flow into the secondary sedimentation chamber 30 through the primary outlet 23, and as shown in FIG. 3, the first outflow partition plate 27 of the primary sedimentation chamber has a first flow inside the primary sedimentation chamber. The front side of the outlet 23 is blocked and the bottom side is opened, and is mounted separately on the inner wall of the primary sedimentation chamber.

図４に示すように、前記放流待機室４０と前記２次沈殿室３０との間には２次沈殿室の第２流出口３１が形成されることにより、最終処理水が放流待機室４０に放流される。また、２次沈殿室３０の第２流出隔板３３が前記２次沈殿室の内部で第２流出口３１の前方を遮るともに底面側が開放された状態で前記２次沈殿室３０の内壁から一定間隔で離隔して装着されている。   As shown in FIG. 4, a second outlet 31 of the secondary sedimentation chamber is formed between the discharge standby chamber 40 and the secondary sedimentation chamber 30, so that the final treated water is supplied to the discharge standby chamber 40.

It is mounted at intervals.

図４および図６に示すように、前記２次沈殿室３０内には、多様な形態の濾材５１からなった吸着濾過手段５０が設けられていることにより、浮遊物質、溶存性汚染物質および重金属などが吸着、除去される。   As shown in FIG. 4 and FIG. 6, the secondary sedimentation chamber 30 is provided with an adsorption filtering means 50 made of various forms of filter media 51, so that floating substances, dissolved pollutants and heavy metals are present. Are adsorbed and removed.

一方、前記１次沈殿室２０の第１流入隔板２５および第１流出隔板２７と前記２次沈殿室３０の第２流出隔板３３の上部には排気口２５ａ、２７ａ、３３ａがそれぞれ設けられることにより、空気による流体流動妨害を防止する。   On the other hand, exhaust ports 25a, 27a, and 33a are provided at the upper portions of the first inflow partition plate 25 and the first outflow partition plate 27 of the primary sedimentation chamber 20 and the second outflow partition plate 33 of the secondary sedimentation chamber 30, respectively. This prevents the fluid flow from being obstructed by air.

図１および図２に示すように、前記流入待機室１０、前記１次沈殿室２０、前記２次沈殿室３０、および前記放流待機室４０には、前記隔板２５、２７、３３および前記吸着濾過手段５０と各室１０、２０、３０、４０の維持管理のための蓋Ｃ１、Ｃ２、Ｃ３、Ｃ４が設けられている。特に、前記２次沈殿室３０の蓋Ｃ３は、板状の濾材５１の投入および分離を容易にするため、四角形になっている。   As shown in FIGS. 1 and 2, the inflow standby chamber 10, the primary sedimentation chamber 20, the secondary sedimentation chamber 30, and the discharge standby chamber 40 include the partition plates 25, 27, 33 and the adsorption. Lids C1, C2, C3, and C4 for maintaining and managing the filtering means 50 and the respective chambers 10, 20, 30, and 40 are provided. In particular, the lid C3 of the secondary sedimentation chamber 30 has a quadrangular shape in order to facilitate the loading and separation of the plate-shaped filter medium 51.

降雨が始まると、地表面および浅い地中の浮遊物質、土砂、汚染物質などが降雨とともに雨水流入口１１を介して流入待機室１０に流入される。この非点汚染物質のうち、粒子の大きい浮遊物質と土砂は流入待機室１０で沈殿され、残りの汚染物質は１次沈殿室２０および２次沈殿室３０を通過する過程で、初期雨水内に含まれた非点汚染源が分離、除去され、最終処理水が放流待機室４０を経由し放流口４１を介して放流される。   When the rain starts, suspended substances, earth and sand, pollutants, etc. in the ground surface and shallow ground flow into the inflow standby chamber 10 through the rainwater inlet 11 along with the rain. Of these non-point pollutants, suspended particulate matter and sediment with large particles are settled in the inflow standby chamber 10, and the remaining pollutants enter the initial rainwater in the process of passing through the primary sedimentation chamber 20 and the secondary sedimentation chamber 30. The contained non-point contamination source is separated and removed, and the final treated water is discharged via the discharge outlet 41 via the discharge standby chamber 40.

以下、本発明による非点汚染源除去装置の各部に対する設計因子、および汚染物除去作用についてより詳細に説明する。   Hereinafter, the design factor for each part of the non-point contamination source removing apparatus according to the present invention and the contaminant removal action will be described in more detail.

まず、雨水流入口１１、流入待機室１０、放流待機室４０、および放流口４１は、梅雨期の洪水に浸水されないように、既存の計画雨水量算定指針にしたがい、該当地域の降雨記録資料または土地利用計画、排水面積などの資料に基づいて設計し、流入待機室１０と放流待機室４０は、１日降雨量６〜１５ｍｍ、好ましくは１０ｍｍ（以下では、１０ｍｍの場合を挙げて説明する）が１時間内に流入された場合、設置地域の条件によって１分〜１０分の範囲で滞留時間を決めるとよい。   First, the rainwater inlet 11, the inflow waiting room 10, the discharge waiting room 40, and the outlet 41 are not subject to flooding during the rainy season, according to the existing planned rainwater calculation guidelines, Designed based on materials such as land use plan, drainage area, etc., the inflow waiting room 10 and the discharge waiting room 40 have a daily rainfall of 6 to 15 mm, preferably 10 mm (hereinafter, 10 mm will be described) If the water flows in within 1 hour, the residence time may be determined in the range of 1 to 10 minutes depending on the conditions of the installation area.

本発明の非点汚染源除去装置においては、１日１時間内の降雨量１０ｍｍが前記流入待機室１０と放流待機室４０のそれぞれに滞留する時間が１〜１０分である。   In the non-point contamination source removing apparatus of the present invention, the time during which rainfall of 10 mm within one hour per day stays in each of the inflow standby chamber 10 and the discharge standby chamber 40 is 1 to 10 minutes.

本発明においては、初期雨水が雨水流入口１１と流入待機室１０に流入され、まず１次沈殿室２０と２次沈殿室３０に流入されて汚染物が処理されるようにするため、１次沈殿室の第１流入口２１の高さが越流ゲート１３の高さと同一にまたはそれより低く設置されることが好ましいが、これは設置地域の条件によって変更可能である。   In the present invention, the initial rainwater flows into the rainwater inlet 11 and the inflow standby chamber 10 and first flows into the primary sedimentation chamber 20 and the secondary sedimentation chamber 30 so that the contaminants are treated. It is preferable that the height of the first inlet 21 of the sedimentation chamber is set equal to or lower than the height of the overflow gate 13, but this can be changed according to the conditions of the installation area.

前記１次沈殿室２０の第１流入口２１と前記２次沈殿室３０の第２流出口３１の大きさは、１日降雨量１０ｍｍが１時間内に流入または流出されるように設計するが、当該地域の降雨量が多くて集中豪雨が頻繁な地域の場合は、０．５時間内に１０ｍｍが流入されるように設計してもよい。   The sizes of the first inlet 21 of the primary sedimentation chamber 20 and the second outlet 31 of the secondary sedimentation chamber 30 are designed so that a daily rainfall of 10 mm flows in or out in one hour. In the case of a region where the amount of rainfall in the region is large and frequent torrential rain is frequent, it may be designed so that 10 mm flows in within 0.5 hours.

本発明において、１次沈殿室の第１流入口２１と２次沈殿室の第２流出口３１の大きさは、１日降雨量１０ｍｍが前記１次沈殿室の第１流入口２１と２次沈殿室の第２流出口３１を介して０．５〜１．０時間内に流入または流出されるように決定される。   In the present invention, the size of the first inlet 21 of the primary sedimentation chamber and the second outlet 31 of the secondary sedimentation chamber is such that the daily rainfall amount is 10 mm and the primary inlet 21 and secondary of the primary sedimentation chamber. It is determined to flow in or out through the second outlet 31 of the settling chamber within 0.5 to 1.0 hour.

図２〜図５に示すように、１次沈殿室の第１流入隔板２５、１次沈殿室の第１流出隔板２７、および２次沈殿室の第２流出隔板３３は、それぞれ１次沈殿室の第１流入口２１、１次沈殿室の第１流出口２３および２次沈殿室の第２流出口３１の全体を覆うように設けられ、それぞれの横幅と各流入口または流出口の内径（Ｄ）の比が１．５〜２．０：１、それぞれの縦幅と各有効水深（Ｈ）の比が１：０．４〜０．６、前記流出口および流入口が形成された内壁と隔板との離隔距離が１００〜３００ｍｍであることが、円滑な汚水の流通と汚染物質の分離のために好ましい。   As shown in FIGS. 2 to 5, the first inflow partition 25 of the primary sedimentation chamber, the first outflow partition 27 of the primary sedimentation chamber, and the second outflow partition 33 of the secondary sedimentation chamber are each 1 The first inlet 21 of the secondary sedimentation chamber 21, the first outlet 23 of the primary sedimentation chamber and the second outlet 31 of the secondary sedimentation chamber are provided so as to cover the entire width and each inlet or outlet. The ratio of the inner diameter (D) is 1.5 to 2.0: 1, the ratio of the respective longitudinal width to each effective water depth (H) is 1: 0.4 to 0.6, and the outlet and the inlet are formed. The separation distance between the inner wall and the partition plate is preferably 100 to 300 mm for smooth circulation of sewage and separation of contaminants.

ここで、前記隔板の上部に設けられる排気口２５ａ、２７ａ、３３ａの内径は２０〜５０ｍｍ、長さは１００〜３００ｍｍであり得る。前記各隔板と排気口を形成する管は、合成樹脂（ポリエチレン）、繊維強化プラスチック（ＦＲＰ）、またはステンレスなどで製造できる。   Here, the inner diameters of the exhaust ports 25a, 27a, 33a provided in the upper part of the partition plate may be 20 to 50 mm and the length may be 100 to 300 mm. The pipes forming the partition plates and the exhaust ports can be manufactured from synthetic resin (polyethylene), fiber reinforced plastic (FRP), stainless steel, or the like.

前記１次沈殿室２０においては、流入待機室１０で沈殿されていない汚染物が沈殿され、上部には、オイル、グリースなどのように、水より比重の低い有機汚染物質などが分離され、処理水は１次沈殿室２０の第１流出隔板２７を通過し１次沈殿室２０の第１流出口２３を介して２次沈殿室３０に流入される。   In the primary sedimentation chamber 20, contaminants that have not yet settled in the inflow standby chamber 10 are settled, and organic pollutants having a specific gravity lower than that of water, such as oil and grease, are separated in the upper part and treated. Water passes through the first outflow separator 27 of the primary sedimentation chamber 20 and flows into the secondary sedimentation chamber 30 via the first outlet 23 of the primary sedimentation chamber 20.

一方、１次沈殿室２０の内壁に装着される第１流入隔板２５と第１流出隔板２７が底面部から有効水深（Ｈ）の２／５Ｈ〜３／５Ｈの高さに設置されることが、水より比重の低い汚染物が全体汚水中で占める体積を考慮して、浮遊有機汚染物の適切な分離のために好ましい。   On the other hand, the 1st inflow partition plate 25 and the 1st outflow partition plate 27 with which the inner wall of the primary sedimentation chamber 20 is mounted are installed in the height of 2 / 5H-3 / 5H of an effective water depth (H) from a bottom face part. This is preferable for the proper separation of floating organic contaminants, taking into account the volume occupied by contaminants of lower specific gravity than water in the overall wastewater.

言い換えれば、オイルまたはグリースなどのように、水より比重の低い汚染物が１次沈殿室２０に流入されると、図３に斜線で示すように分離され、浮遊物は放流されないので、汚染物質は降雨時または降雨が止んだとき、取り出して易く除去することができる。   In other words, when pollutants having a specific gravity lower than that of water, such as oil or grease, flow into the primary sedimentation chamber 20, they are separated as shown by hatching in FIG. 3, and the suspended matter is not discharged. Can be easily removed and removed when it rains or when it stops.

ついで、前記２次沈殿室３０においては、１次沈殿室２０で沈殿、分離されていない物質を沈殿、分離させるとともに、２次沈殿室３０内に取り付けられる吸着濾過手段５０により溶存性有機物と重金属のような汚染物などが吸着、除去され、ついで処理水は２次沈殿室３０の第２流出隔板３３と第２流出口３１を介して放流待機室４０に流入した後、放流口４１を介して最終に放流される。   Next, in the secondary sedimentation chamber 30, substances that are not precipitated and separated in the primary sedimentation chamber 20 are precipitated and separated, and dissolved organic substances and heavy metals are absorbed by the adsorption filtration means 50 attached in the secondary sedimentation chamber 30. Then, the treated water flows into the discharge standby chamber 40 via the second outlet plate 33 and the second outlet 31 of the secondary sedimentation chamber 30, and then flows into the outlet 41. And finally released.

前記２次沈殿室３０の内壁に装着された第２流出隔板３３は底面から有効水深（H）の２／５〜３／５の高さに設定されるので、１次沈殿室２０で分離されなくて２次沈殿室３０に流入したオイルまたはグリースなどの有機汚染物質のように比重の低い汚染物質は、図４に斜線で示すように、もう一度分離される。   Since the second outflow diaphragm 33 mounted on the inner wall of the secondary sedimentation chamber 30 is set to a height of 2/5 to 3/5 of the effective water depth (H) from the bottom surface, it is separated in the primary sedimentation chamber 20. A contaminant having a low specific gravity, such as an organic contaminant such as oil or grease, which has not been flown into the secondary sedimentation chamber 30, is separated once again as shown by the hatched lines in FIG.

このように、２次沈殿室３０に隔板が設置される理由は、一定期間にオイルおよびグリースなどの物質が過多に流入したか、または掃除などの維持管理が足りなくて、１次沈殿室２０内で浮遊する汚染物が容量を超える場合、２次沈殿室３０に汚染物質が流入することになるとき、この流入汚染物質を除去するためのものである。   As described above, the reason why the partition plate is installed in the secondary sedimentation chamber 30 is that a large amount of substances such as oil and grease have flowed in for a certain period of time, or maintenance such as cleaning is insufficient, and the primary sedimentation chamber. When the contaminants floating in 20 exceed the capacity, when the contaminants flow into the secondary sedimentation chamber 30, the inflow contaminants are removed.

図６は吸着濾過手段５０として使用される濾材５１の一実施形態を示す。
本発明に使用される吸着濾過手段５０は、ポリエチレン、高密度ポリエチレン（ＨＤＰＥ）、繊維強化プラスチック、ステンレスのいずれか１種から製造可能であり、前後面に多数の孔が穿孔されている。前記各孔の径は１ｍｍ〜５ｍｍが好ましい。 FIG. 6 shows an embodiment of the filter medium 51 used as the adsorption filtration means 50.
The adsorptive filtration means 50 used in the present invention can be manufactured from any one of polyethylene, high density polyethylene (HDPE), fiber reinforced plastic, and stainless steel, and a large number of holes are perforated on the front and rear surfaces. The diameter of each hole is preferably 1 mm to 5 mm.

前記吸着濾過手段５０は多数の濾材５１から構成可能であり、各濾材５１の厚さは３０ｍｍ〜１００ｍｍのブロック型であり得る。前記吸着濾過手段５０の濾材５１には、吸着物質として活性炭、膨張性蛭石、膨張性パーライト、ゼオライトまたはこれらの混合物を充填できる。前記濾材に充填される吸着物質の種類は本発明の装置が設定される地域によって選択される。   The adsorption filtering means 50 can be composed of a large number of filter media 51, and the thickness of each filter media 51 can be a block type of 30 mm to 100 mm. The filter medium 51 of the adsorption filtration means 50 can be filled with activated carbon, expansive meteorite, expansive pearlite, zeolite or a mixture thereof as an adsorbing substance. The kind of the adsorbing substance filled in the filter medium is selected according to the region where the apparatus of the present invention is set.

前記吸着濾過手段５０の濾材５１内に充填される吸着物質の種類による機能は次のようである。   The function according to the kind of the adsorbing substance filled in the filter medium 51 of the adsorption filtering means 50 is as follows.

活性炭は、周知のように、溶存性有機物質および重金属などを吸着除去する機能をし、膨張性蛭石は、一般に金雲母および黒雲母を指す蛭石を熱処理して膨張させたメディアであって、現在地球上で知られた鉱物のうち、陽イオン交換能力が最も大きい鉱物質であり、鉄、銅、亜鉛、クロム、鉛、水銀などを除去する機能をする。また、膨張性パーライトは火山活動により生成された天然鉱物である真珠岩の体積を数十倍に膨張させて作った超軽量の多角質の白色粒子であって、窒素、燐および油分の除去に優れた効能を有し、ゼオライトは凝灰岩の変性物であって、珪酸アルミニウムなど、陽イオン交換機能を有する天然鉱物であり、重金属の吸着および水中のアンモニアおよび窒素の除去に優れた効能を持っている。このような吸着物質が吸着濾過手段５０の濾材５１内に充填されることにより、溶存性汚染物質および重金属などの除去に優れた効能を有する。   As is well known, activated carbon has a function of adsorbing and removing dissolved organic substances and heavy metals, and expansive meteorite is a medium that is expanded by heat treatment of meteorites generally indicating phlogopite and biotite. Among the minerals currently known on the earth, it has the largest cation exchange capacity and functions to remove iron, copper, zinc, chromium, lead, mercury and the like. In addition, expansive perlite is an ultralight multi-colored white particle made by expanding the volume of nacre, a natural mineral produced by volcanic activity, several tens of times. It is used to remove nitrogen, phosphorus and oil. Zeolite is a modified tuff and is a natural mineral that has a cation exchange function, such as aluminum silicate. It has excellent efficacy for heavy metal adsorption and removal of ammonia and nitrogen in water. Yes. By filling such an adsorbing substance in the filter medium 51 of the adsorbing filtration means 50, it has an excellent effect in removing dissolved pollutants and heavy metals.

前記濾材５１は前記吸着濾過手段５０をなすハウジングにジグザグ状に配列されることにより、処理水との接触面積が増大できる。前記吸着手段５０の濾材５１は前記２次沈殿室３０内に少なくとも１組が設置され、濾過効率をさらに増大させるため３組以上設置できる。しかし、設置場所および条件によって、汚染濃度が高いところでは設置台数を増やすことができる。吸着濾過手段５０を複数設置する場合、掃除および維持管理のため、設置間隔は３００ｍｍ〜１０００ｍｍとする。   By arranging the filter media 51 in a zigzag manner in the housing that forms the adsorption filtration means 50, the contact area with the treated water can be increased. At least one set of filter media 51 of the adsorbing means 50 is installed in the secondary sedimentation chamber 30, and three or more sets of filters can be installed to further increase the filtration efficiency. However, depending on the installation location and conditions, the number of installations can be increased where the contamination concentration is high. When installing a plurality of adsorption filtration means 50, the installation interval is set to 300 mm to 1000 mm for cleaning and maintenance management.

１次沈殿室２０と２次沈殿室３０を通過しながら汚染物質が除去された処理水は放流待機室４０と放流口４１を介して川または湖沼などに放流される。   The treated water from which contaminants have been removed while passing through the primary sedimentation chamber 20 and the secondary sedimentation chamber 30 is discharged to a river or a lake through a discharge standby chamber 40 and a discharge port 41.

本発明の非点汚染源除去装置Ｒは、コンクリート、繊維強化プラスチック、高密度ポリエチレンなどの材質から製造可能である。   The astigmatism source removing device R of the present invention can be manufactured from materials such as concrete, fiber reinforced plastic, high density polyethylene and the like.

一方、本発明の非点汚染源除去装置は、流体の逆流防止、および円滑な処理のため、１次沈殿室２０と２次沈殿室３０との間に５０ｍｍ〜１００ｍｍの水頭差（図示せず）を有することが好ましい。   On the other hand, the non-point contamination source removing apparatus of the present invention has a water head difference (not shown) of 50 mm to 100 mm between the primary sedimentation chamber 20 and the secondary sedimentation chamber 30 for preventing backflow of fluid and smooth processing. It is preferable to have.

また、本発明において、１次沈殿室２０と２次沈殿室３０での流体滞留時間は、設置場所および条件に応じて、１０分〜２４０分の範囲で設定することができる。   Moreover, in this invention, the fluid residence time in the primary sedimentation chamber 20 and the secondary sedimentation chamber 30 can be set in the range of 10 minutes-240 minutes according to an installation place and conditions.

一方、降雨が始まった後、降雨量が１０ｍｍを越えて流入した降雨は汚染物質が殆どない雨水であるので、これは越流ゲート１３を介して放流待機室４０に流入し、放流口４１を介して放流される。   On the other hand, after the rain has started, the rain that has flowed in over 10 mm is rainwater that is almost free from pollutants, so that it flows into the discharge standby chamber 40 via the overflow gate 13 and enters the discharge port 41. It is discharged through.

前記流入待機室１０および前記放流待機室４０と、前記１次沈殿室の流出隔板２７および前記吸着濾過手段５０の上部にはそれぞれ蓋Ｃ１、Ｃ２、Ｃ３、Ｃ４が設けられるので、本発明の装置を便利に使用することができる。   Lids C1, C2, C3, and C4 are provided on the inflow standby chamber 10, the discharge standby chamber 40, the outflow separation plate 27 of the primary sedimentation chamber, and the adsorption filtration means 50, respectively. The device can be conveniently used.

本発明の非点汚染源除去装置の維持管理は度々行うことが処理効率の面でよいが、経済性を考慮して、少なくとも春季、梅雨前後など、適正時期を選択して、１年に１回または２回くらい定期的に行うことが好ましい。   The maintenance of the non-point contamination source removal apparatus of the present invention may be performed frequently in terms of processing efficiency. However, in consideration of economy, at least once in the spring, before and after the rainy season, etc. Or it is preferable to carry out about twice regularly.

また、吸着濾過手段５０内に充填された活性炭、膨張性蛭石、ゼオライト、膨張性パーライトなどは、汚染発生地域によって違うが、１年ないし２年を周期として交換するとよい。   Further, the activated carbon, expansive meteorite, zeolite, expansive pearlite, etc. filled in the adsorption filtration means 50 may be exchanged with a period of one to two years, although it varies depending on the contamination occurrence area.

前述したように、初期降雨６〜１５ｍｍで降った降雨による非点汚染源の処理を保障する本発明の非点汚染源除去装置を用いると、雨汚水による川または湖沼の汚染を効果的に防止することができる。   As described above, the use of the non-point pollution source removing device according to the present invention that ensures the treatment of the non-point pollution source due to the rainfall that has fallen at an initial rainfall of 6 to 15 mm effectively prevents the river or lake from being polluted by rain sewage.
