The high-concentration wastewater treatment system of the present invention is a wastewater treatment system without an opening that reduces the molecular weight of an inflowing organic substance ranging from a low concentration to a high concentration by combining an activated sludge method and a sprinkling filter bed method. A device for irradiating light to a plurality of tanks with a light emitting device, an exhausted carbon dioxide CO 2 air collecting tube that uses again carbon dioxide CO 2 generated by microorganisms in each tank for aeration at each mixing ratio, and the inside of a sprinkling filter bed tank A high-concentration wastewater treatment system characterized by having a discharge vent pipe that quickly releases inorganic N 2 that has been reduced in molecular weight and separated from organic matter to the atmosphere, and a dissolved oxygen auxiliary device that enhances the dissolved oxygen effect by a blower. is there.
本発明の高濃度排水処理システムは、自然の光を利用できない開口部の無い処理環境で流入する高濃度の廃水液に対応する事を目的とし、人工の光を連続照射して光合成を活発化させ微生物群の安定増殖を充実させる基礎となる第一次補食材の安定供給を整える環境を提供する。従来の構造で太陽光を利用した場合、夜間の光合成は得られない、更に天候によっても左右される。そこで植物育成に必要な特有波長が４００ｎｍ，５００ｎｍ，６００ｎｍを選択する、照度が８，０００ルックスから２０，０００ルックスである光を各槽の天井や壁から連続照射し安定した確実な光合成を人工的に促す。３５億年前の化石より、初めて地球上に誕生した微生物としてラン藻類が記録されている。自然界に於ける生物群の構築の源は０．００１ｍｍから０．００２ｍｍの小さな微生物を第一次補食材とし、捕食した微生物は次の生物に捕食されその安定した食物連鎖が自然界の浄化構成を成立させている。本発明での生物処理は食品製造用微生物の数種を集積培養した液を濾床層に移植した後に、その微生物群を取り巻く人工的に作る事のできない多くの微生物が誕生しそれぞれの役割で活動する事を利用する。そうした自然界の微生物の総合作用で、高濃度で窒素成分の多い畜産排水の生物化学的酸素要求量ＢＯＤ１９，０００ｐｐｍであっても、１２０時間滞留時間の微生物処理でＢＯＤ１７ｐｐｍに浄化する能力を発揮する。有機性物質を低分子化し、酸化させ、還元させ、自然界の微生物が食物連鎖を繰り返し活動しながら、浄化する環境造りをする上で発光装置は光合成を促進させる重要な役割である。
The high-concentration wastewater treatment system of the present invention activates photosynthesis by continuously irradiating artificial light for the purpose of dealing with high-concentration wastewater liquid that flows in a treatment environment without openings that cannot use natural light. It provides an environment that provides a stable supply of primary supplementary foods that will serve as a basis for enhancing the stable growth of microorganisms. When sunlight is used in a conventional structure, nighttime photosynthesis cannot be obtained, and it also depends on the weather. Therefore, we select artificial wavelengths of 400nm, 500nm and 600nm that are necessary for plant growth, and continuously irradiate light from 8,000 lux to 20,000 lux from the ceiling and walls of each tank to produce stable and reliable photosynthesis. Promptly. Cyanobacteria are recorded as the first microorganisms born on the earth from a fossil of 3.5 billion years ago. The source of construction of organisms in nature is a small microorganism of 0.001mm to 0.002mm as a primary supplement, and the predated microorganisms are preyed on by the next organism, and its stable food chain forms a purification structure in nature. It has been established. In the biological treatment according to the present invention, after transplanting a liquid obtained by accumulating several kinds of microorganisms for food production to the filter bed layer, many microorganisms surrounding the microorganism group that cannot be artificially created are born and have their respective roles. Take advantage of activities. With such a comprehensive action of microorganisms in the natural world, even if the biochemical oxygen demand BOD is 19,000 ppm for livestock wastewater with a high concentration and a high nitrogen content, the ability to purify to 17 ppm BOD by microbial treatment for 120 hours residence time. Light emitting devices play an important role in promoting photosynthesis in reducing the molecular weight of organic substances, oxidizing them, reducing them, and creating a clean environment where natural microorganisms repeatedly act in the food chain.
本発明の高濃度排水処理システムは、流入する高濃度の廃水液に対応する微生物群は、連鎖をしながら変化する環境に於いて増殖しつつ活動をする、そうした自然界の仕組みに合致させる為の環境が提供する処理過程で微生物が発生する二酸化炭素ＣＯ２を、通常曝気と混合させ微細藻類の増殖環境を充実させて微細藻類を光合成により多量合成する際、同時に発生する未合成の余剰有機物を安定生産する為、微生物の活動で発生した二酸化炭素ＣＯ２を回収し再利用をする。水に溶けた二酸化炭素ＣＯ２は重炭酸イオンＨＣＯ３−と変化しそれが藻類等の酵素により二酸化炭素に変換されて、水素Ｈと結合し新有機物ＣｎＨｍＯｐする微細藻類が生まれる。同時に発生する未結合の余剰有機物は菌類の餌や又菌類の増殖過程に利用され、食物連鎖の重要な第一次補食材の安定した供給に繋がる。大気中の二酸化炭素濃度は０．０３５％と低く微生物が放出した二酸化炭素の再利用は食物連鎖の循環に効率良く働く、各槽に設けた集気装置から二酸化炭素ＣＯ２を回収し、ＢＯＤ量に応じ送風機にて曝気量に対し集気装置で回収した量を２０：１から５：１の割合で送風する。
The high-concentration wastewater treatment system of the present invention is designed to match the natural structure in which the microorganisms corresponding to the inflowing high-concentration wastewater are active while multiplying in a chain-changing environment. When carbon dioxide CO 2 generated by microorganisms in the treatment process provided by the environment is mixed with normal aeration to enrich the growth environment of microalgae to synthesize a large amount of microalgae by photosynthesis, unsynthesized surplus organic matter generated at the same time For stable production, carbon dioxide CO 2 generated by the activity of microorganisms is recovered and reused. Carbon dioxide CO 2 dissolved in water is changed to bicarbonate ion HCO 3 −, which is converted to carbon dioxide by an enzyme such as algae, and is combined with hydrogen H to produce microalgae that forms a new organic substance CnHmOp. The unbound surplus organic matter generated at the same time is used for fungal food and fungal growth processes, leading to a stable supply of important primary supplements in the food chain. The carbon dioxide concentration in the atmosphere is as low as 0.035%, and the reuse of carbon dioxide released by microorganisms works efficiently in the circulation of the food chain. Carbon dioxide CO 2 is recovered from the air collector installed in each tank, and BOD The amount collected by the air collector is blown at a ratio of 20: 1 to 5: 1 with respect to the aeration amount by a blower according to the amount.
本発明の高濃度排水処理システムに於いて、火山性の軽石状の天然鉱石と貝殻を重鎮し積み重ねた散水濾床に廃水成分の有機性物質を分解する能力を有す微生物を移植し、好気性菌あるいは嫌気性菌の持つ能力を自然界の仕組みに沿い、最大に活用する散水濾床方式を併せ持つ。散水濾床層の同一な容積内で好気性菌と通性嫌気性菌と弱嫌気性菌そして嫌気性菌が活動し、早い分解速度のもとで低分子化且つ硝化に至った硝酸ＮＯ３は、通性嫌気性である脱窒細菌によって酸素Ｏと窒素ガスＮ２に分解され、窒素ガスＮ２は一部光合成に利用される、散水濾床層内部を活性化する目的で窒素ガスＮ２集気管を設けて排出する。脱窒反応によって窒素化合物を窒素ガスまで分解すると同時に有機物除去が行われるので、余剰汚泥量を従来の０．２から０．１４と極めて少量化でき、本発明のシステムに於いて重要な働きである。
In the high-concentration wastewater treatment system of the present invention, a microorganism having the ability to decompose organic substances of wastewater components is transplanted to a sprinkling filter bed in which volcanic pumice-like natural ore and shells are piled up and stacked. In addition to the ability of aerobic bacteria or anaerobic bacteria, along with the structure of nature, it also has a sprinkling filter bed system that makes the most of it. NO 3 nitrate, which has become a low molecular weight and nitrified under the fast decomposition rate, with aerobic bacteria, facultative anaerobic bacteria, weak anaerobic bacteria and anaerobic bacteria active in the same volume of the sprinkling filter bed Is decomposed into oxygen O and nitrogen gas N 2 by denitrifying bacteria that are facultative anaerobic, and nitrogen gas N 2 is partially used for photosynthesis. Nitrogen gas N is used for the purpose of activating the inside of the sprinkling filter bed layer. 2 Provide a gas collection tube and discharge. Since nitrogen compounds are decomposed to nitrogen gas by denitrification reaction and organic matter removal is performed at the same time, the amount of excess sludge can be extremely reduced from 0.2 to 0.14, which is an important function in the system of the present invention. is there.
本発明の高濃度排水処理システムは、効率のよい溶存酸素を供給する目的で溶存酸素補助器を使用する。本システムの溶存効果は従来の散気管だけで曝気する方法と比較して、５％から２０％上昇させる事が出来る。微生物が消費する酸素量より供給酸素量が常に上回っていなければならない環境で、小さな送風機の送風量で理想的な効果を得られる。構造上の面では水圧が下がる過程で気泡玉が大きくなるものを再び小さな気泡玉にしながら湾曲した空気溜まりに気泡玉を留め、気泡玉は水膜の接触面積に触れながら滞留時間を長くする事で溶存効果を得る。よって従来の水槽深度より０．５ｍから１．０ｍ浅くする事ができ構造上有利な結果が得られる。一方水圧も０．０５から０．１ポイント水圧が低くなるので吐出させる送風エネルギーの削減もできる。
The high-concentration wastewater treatment system of the present invention uses a dissolved oxygen auxiliary device for the purpose of supplying efficient dissolved oxygen. The dissolved effect of this system can be increased by 5% to 20% compared to the conventional method of aeration only with a diffuser. In an environment where the amount of supplied oxygen must always exceed the amount of oxygen consumed by microorganisms, an ideal effect can be obtained with a small blower. In terms of structure, the bubble ball is retained in a curved air pocket while changing the bubble bubble that becomes larger as the water pressure is lowered into a small bubble ball, and the bubble ball makes the residence time longer while touching the contact area of the water film. Get the dissolved effect. Therefore, the depth can be made 0.5 m to 1.0 m shallower than the depth of the conventional water tank, and a structurally advantageous result can be obtained. On the other hand, since the water pressure is also reduced by 0.05 to 0.1 point, the blown energy to be discharged can be reduced.
図１の１９は溶存酸素補助器を示す。従来の散気方式は床から吐出する微細な気泡を発する。水圧が下がるに反比例し気泡玉は大きくなり、上昇加速度が加わり早く液面に到達し、すぐ大気に出て効率が悪い。そこで溶存酸素補助器は底部で吐出した空気が上昇する過程で、空気が次から次に気泡玉粉砕板によって大きくなっては小さくされ、その繰り返しをする途中で図６の３８に示す水膜接触材などが主に酸素と廃液とを接触させる役割をしており、長い時間液中に気泡玉を留め接触させる。従来の散気管と比較すると同一送風量で１８％から２３％増の酸素の溶存効果を得られた。高濃度の廃液に対応する微生物量は多く、その酸素の供給量は当然多く求められ、微生物の活動にもっとも適した酸素量を満たす事は重要である。更に従来の散気方法の場合は水温の変動や水深に大きく左右され、多量の曝気量を送る必要があったが本溶存酸素補助器はその必要がない。溶存酸素補助器を従来の散気管と併用する事で送風機を小さくできる。又、水槽構造物の深さを従来より０．５ｍから１．０ｍ浅くしても充分な酸素量が得られるので耐圧構造上も有利になる排水処理方式となる。
Reference numeral 19 in FIG. 1 denotes a dissolved oxygen assist device. Conventional aeration systems emit fine bubbles that are discharged from the floor. Inversely proportional to the drop in water pressure, the bubble bubble becomes larger, the rising acceleration is added, the liquid level is reached quickly, and it immediately goes out to the atmosphere and is inefficient. Therefore dissolved oxygen aids in the process of air discharged at the bottom rises, air is small is larger by then bubble ball milling plate from following the water film shown in 3 8 6 in the course of the repeated The contact material or the like mainly plays a role of bringing oxygen into contact with the waste liquid, and holds the bubble balls in the liquid for a long period of time. Compared with the conventional air diffuser, the effect of dissolved oxygen was increased by 18% to 23% with the same air flow. The amount of microorganisms corresponding to a high concentration waste liquid is large, and the supply amount of oxygen is naturally required to be large. It is important to satisfy the oxygen amount most suitable for the activity of microorganisms. Furthermore, in the case of the conventional aeration method, it depends greatly on the fluctuation of the water temperature and the water depth, and it is necessary to send a large amount of aeration, but this dissolved oxygen auxiliary device is not necessary. A blower can be made small by using a dissolved oxygen auxiliary device together with a conventional diffuser. Moreover, even if the depth of the water tank structure is 0.5 m to 1.0 m shallower than the conventional depth, a sufficient amount of oxygen can be obtained.
