종래의 기술은 인을 제거하기 위하여 유입원수를 혐기조에 넣고 인을 용출시킴으로써 무산소조에서 충분한 탄소원으로 작용하지 못하였으며 슬러지나 방류수중의 휘발성유기물질을 제거하기 위하여 분말활성탄등을 사용하였으나 이는 비용이 많이 들고 분말활성탄에 의한 탁도저하, 운전이 용이하지 못한 문제점이 있다.그리고 하·폐수의 질소와 인을 제거하기 위하여 사용되는 A2O공정은 혐기조에서 인을 용출시켜 호기조에서 인을 과잉섭취하여 인이 흡수된 슬러지를 제거함으로써 인을 제거하는 공정이다. 그러나 상기 공정의 혐기조에 원수가 유입될 경우 원수중의 탄소원이 반송슬러지중에 함유된 질산성질소를 제거하거나 인을 용출시키는데 사용되어 무산소조의 탄소원으로 작용하지 못하게 되는 문제점이 있다.한편, 하·폐수의 처리수를 방류할 경우 휘발성유기물질(VOC)이 그대로 배출되며 소독과정을 거치지 않아 하천에 악영향을 미치고 있다. 중수처리 또는 정수장의 소독과정에서 사용하는 염소소독의 경우 발암성물질인 트리할로메탄(THM)이나 유기염소계 화합물을 발생시켜 인체에 해를 끼치고 있다.본 발명은 하·폐수처리과정의 외부반송슬러지나 내부반송슬러지의 미생물을 파괴하여 질산성질소와 인을 용출시키고, 휘발성유기물질을 제거함으로써 처리장으로 유입되는 유입원수가 충분한 탄소원으로 활용될 수 있도록 한다, 아울러 본 발명이 혐기조나 혐기성소화조에 활용되어 슬러지를 파괴하고 휘발성유기물질을 제거하고 슬러지를 감량시키는데 이용된다.또한 하·폐수처리의 최종침전지나 처리수관에 사용하거나 중수, 정수장의 처리수에 사용되어 처리수중의 휘발정유기물을 분해하고 미생물을 소독하는 과정에 사용되어 유해성을 예방할 수 있다.Conventional techniques have not used sufficient carbon source in an anoxic tank by inflowing inlet water into an anaerobic tank to remove phosphorus and using powdered activated carbon to remove volatile organic substances in sludge or effluent. In addition, the turbidity decrease due to the activated activated carbon powder and the operation is not easy.The A2O process, which is used to remove nitrogen and phosphorus from sewage and wastewater, elutes phosphorus in an anaerobic tank and overtakes phosphorus in an aerobic tank to absorb phosphorus. It is a process of removing phosphorus by removing the sludge. However, when the raw water is introduced into the anaerobic tank of the process, there is a problem that the carbon source in the raw water is used to remove nitrate nitrogen contained in the conveying sludge or elute phosphorus, so that it does not act as a carbon source of the anoxic tank. When the treated water is discharged, volatile organic substance (VOC) is discharged as it is, and it does not go through the sterilization process, which adversely affects the stream. In the case of chlorine disinfection used in the treatment of heavy water treatment or water purification plant, trihalomethane (THM) or organic chlorine compounds, which are carcinogenic substances, are generated to harm the human body. By destroying sludge or internal transport sludge, eluting nitrogen nitrate and phosphorus, and removing volatile organic substances, the inflow water flowing into the treatment plant can be utilized as a sufficient carbon source, and the present invention can be used for anaerobic or anaerobic digestion tanks. It is used to destroy sludge, remove volatile organic substances and reduce sludge.It is also used for final sedimentation or treatment water pipe of sewage and wastewater treatment, or for treatment water of heavy water and water purification plant to decompose volatile organic matter in treated water. It can be used in the process of disinfecting microorganisms to prevent the harmful effects.
