The present invention relates to a facility for reducing non-point pollutants. According to the present invention, the facility for reducing non-point pollutants comprises: a treatment structure which forms a pretreatment tank, a filtration tank, and a reverse washing tank; a screen means which is installed in the pretreatment tank, and filters out floating matter and garbage in a rainfall effluent flowing into the pretreatment tank; and a filtration means which is installed in the filtration tank, and enables heavy non-point pollutants in pretreated water flowing into the filtration tank to be precipitated and absorbs and filters out light non-point pollutants. In addition, the facility for reducing non-point pollutants according to the present invention comprises a reverse washing means which includes a backwash water supply unit that uses filtered water flowing into the reverse washing tank as backwash water to wash filter media and a backwash water discharge unit that discharges the backwash water that has been used to wash the filter media to the outside of the treatment structure.
본 발명은 비점오염물 저감시설에 관한 것으로, 본 발명에 따른 비점오염물 저감시설은 전처리조, 여과조 및 역 세척조를 형성하는 처리 구조물; 전처리조 내에 설치되어 전처리조로 유입되는 강우 유출수 내의 부유물 및 쓰레기를 걸러내는 스크린 수단; 여과조 내에 설치되어 여과조로 유입되는 전처리수 내의 무거운 비점오염물질은 침전시키고 가벼운 비점오염물질은 흡착해 걸러내는 여과수단;을 포함한다. 또한 본 발명에 따른 비점오염물 저감시설은 역 세척조 내로 유입된 여과수를 역 세수로 이용해 여재들을 세척할 수 있게 하는 역 세수 공급부; 및 여재들을 세척한 역 세수를 처리 구조물의 외부로 배출할 수 있게 하는 역 세수 배출부;를 가지는 역 세척 수단;을 더 포함한다.
