次に、以上のように構成された排水浄化装置１を用いて排水を浄化する方法を説明する。   Next, a method for purifying wastewater using the wastewater purification apparatus 1 configured as described above will be described.

まず、排水貯留タンク９０に貯留されている排水を排水供給ライン３１から第１微生物処理槽３に供給した後、排水を微生物で処理する微生物処理工程（ステップＳ１）を行う。具体的には、空気生成装置１１を作動させることにより、曝気管３３から第１微生物処理槽３に空気を供給し、微生物担体チップ３２に生息する微生物を活性させて排水を浄化する。排水を微生物処理すると、微生物によって分解された有機物などが沈殿物として第１微生物処理槽３の底部に滞留する。沈澱物は沈殿物除去ライン３６を介して外部に排出される。微生物処理された排水は連通孔３７を介して第２微生物処理槽４に流入する。続いて、空気生成装置１１から第２微生物処理槽４に空気を供給することにより、活性化石炭４１に生息する微生物を活性させて排水を浄化する。微生物処理工程（Ｓ１）では、微生物担体チップ３２および活性化石炭４１に生息する微生物の一部が排水の水流により排水中に流出する。微生物処理された排水および排水中に流出した微生物は、第１案内ライン６１を介して微生物除去槽６に流入する。   First, after the wastewater stored in the wastewater storage tank 90 is supplied from the wastewater supply line 31 to the first microorganism treatment tank 3, a microbial treatment step (step S1) for treating the wastewater with microorganisms is performed. Specifically, by operating the air generation device 11, air is supplied from the aeration pipe 33 to the first microorganism treatment tank 3, and microorganisms living in the microorganism carrier chip 32 are activated to purify the waste water. When the wastewater is treated with microorganisms, organic matter decomposed by the microorganisms stays at the bottom of the first microorganism treatment tank 3 as a precipitate. The precipitate is discharged to the outside through the precipitate removal line 36. The microbially treated wastewater flows into the second microbial treatment tank 4 through the communication hole 37. Subsequently, by supplying air from the air generation device 11 to the second microorganism treatment tank 4, microorganisms living in the activated coal 41 are activated to purify the waste water. In the microorganism treatment step (S1), a part of the microorganisms that inhabit the microorganism carrier chip 32 and the activated coal 41 flows into the wastewater by the drainage water flow. The microorganism-treated waste water and the microorganisms flowing out into the waste water flow into the microorganism removal tank 6 through the first guide line 61.

次に、微生物除去槽６に流入した排水は、活性炭６２により内部に含まれる微生物が吸着除去される（ステップＳ２）。具体的には、排水中に含まれる微生物は、排水が活性炭６２を通過する際に、活性炭６２に生息し、排水中から排除される。活性炭６２で処理された排水は、第２案内ライン６３を介してオゾン処理槽７に送られる。   Next, the microorganisms contained in the waste water flowing into the microorganism removal tank 6 are adsorbed and removed by the activated carbon 62 (step S2). Specifically, microorganisms contained in the wastewater live in the activated carbon 62 and are excluded from the wastewater when the wastewater passes through the activated carbon 62. The waste water treated with the activated carbon 62 is sent to the ozone treatment tank 7 through the second guide line 63.

その後、排水をオゾン処理して浄化水を生成するオゾン処理工程（ステップＳ３）を行う。具体的には、オゾンガス生成装置７１を作動させることにより、オゾン散気管７２からオゾン処理槽７にオゾンガスを供給し、オゾンの作用により排水の殺菌、消毒、漂白などを行う。また、雨水供給ライン７４からオゾン処理槽７に供給された雨水も同様にオゾン処理する。こうして排水および雨水が浄化されることにより浄化水が生成され、この浄化水は浄化水排出ライン７３を介して浄化水貯留槽８に送られ、貯留される。   Then, the ozone treatment process (step S3) which ozone-treats waste water and produces | generates purified water is performed. Specifically, by operating the ozone gas generation device 71, ozone gas is supplied from the ozone diffusing pipe 72 to the ozone treatment tank 7, and wastewater is sterilized, disinfected, bleached, and the like by the action of ozone. Moreover, the rainwater supplied to the ozone treatment tank 7 from the rainwater supply line 74 is similarly ozone-treated. In this way, purified water is generated by purifying the drainage and rainwater, and this purified water is sent to the purified water storage tank 8 via the purified water discharge line 73 and stored.

浄化水を使用する場合には、送水ポンプ８４を作動させることにより、浄化水貯留槽８から浄化水供給ライン８２へ浄化水を送出し、ユースポイントへ供給する。   When using purified water, by operating the water pump 84, the purified water is sent from the purified water storage tank 8 to the purified water supply line 82 and supplied to the use point.

本実施形態に係る排水浄化装置１によれば、有機性の排水を微生物で処理し、微生物処理された排水に含まれる微生物を活性炭６２により吸着除去し、微生物が除去された排水をオゾンで処理するので、微生物処理における微生物がオゾンで死滅することがなく、十分な量の微生物により微生物処理をすることができる。また、オゾン処理される排水中に含まれる微生物の量を少なくすることができ、オゾン処理で発生する微生物の死骸を少なくすることができる。したがって、清潔な浄化水を得ることができる。   According to the wastewater purification apparatus 1 according to the present embodiment, organic wastewater is treated with microorganisms, microorganisms contained in the microorganism-treated wastewater are adsorbed and removed by activated carbon 62, and wastewater from which microorganisms have been removed is treated with ozone. Therefore, the microorganisms in the microorganism treatment are not killed by ozone, and the microorganism treatment can be performed with a sufficient amount of microorganisms. Further, the amount of microorganisms contained in the wastewater to be treated with ozone can be reduced, and the dead bodies of microorganisms generated by the ozone treatment can be reduced. Therefore, clean purified water can be obtained.

以上、本発明の一実施形態について説明したが、本発明の具体的な態様は、上記実施形態に限定されるものではない。   As mentioned above, although one Embodiment of this invention was described, the specific aspect of this invention is not limited to the said embodiment.

例えば、本実施形態では、微生物除去槽６に収容されたものは活性炭６２であったが、排水中の微生物を吸着して排水から除去できる多孔質体であれば特に限定されず、珪藻土およびゼオライトなどでもよい。   For example, in this embodiment, what was accommodated in the microorganism removal tank 6 was the activated carbon 62, but it is not particularly limited as long as it is a porous body that can adsorb microorganisms in the wastewater and remove it from the wastewater. Diatomaceous earth and zeolite Etc.
