본원발명은 비점오염저감시설, 보다 구체적으로는 비점오염저감시설의 여재를 역세척하는 수단 및 방법에 관한 것이다. 본원발명은 여재로 비점오염물질 여과 후 상기 여재와 여재에 달라붙은 오염물질이 혼재된 여재층 오염수에서 상기 오염물질을 제거하는 '여재 세척 수단'을 포함하는 비점오염저감시설에 있어서; 상기 여재 세척 수단은, 상기 여재와 오염물질이 혼재된 여재층 오염수를 상기 여재층에 형성된 여재 흡인구를 통해 여재 이송라인으로 흡인하는 여재 흡인수단, 상기 여재 흡인수단에 의하여 이송되는 상기 여재와 오염물질이 혼재된 여재층 오염수를 교란시켜 상기 오염물질을 상기 여재로부터 분리되도록 하는 오염물질 탈리기 및 오염물질과 여재가 분리된 상태의 상기 여재층 오염수가 상기 여재층에 재유입되는 여재 재충전구를 포함하는 오염물 탈리 여재 순환 장치인 것을 특징으로 하는 비점오염물질저감시설을 제공한다. 본원발명의 '오염물 탈리 여재 순환 장치'에 따르면 역세척 효율을 증대시킬 수 있어, 최소의 세척수만으로도 여재 세척이 가능한바, 본원발명에 따른 비점오염저감시설 내의 처리수만으로도 여재 세척이 가능하고, 따라서 별도의 처리수조나 역세척수 공급라인을 구비하지 않아도 되어 시공 및 유지·관리의 경제성을 확보할 수 있다.
The present invention relates to a nonpoint pollution reduction facility, and more specifically to, a means and a method for backwashing filter media of the nonpoint pollution reduction facility. The present invention relates to the nonpoint pollution reduction facility including a filter media cleaning means which filters a nonpoint pollutant with the filter media and removes pollutants in filter media layer polluted water in which the filter media and the pollutants attached to the filter media are mixed. The filter media cleaning means is a pollutants desorption filter media circulation device comprising: a filter media suction means suctioning filter media layer polluted water in which the filter media and the pollutants are mixed to a filter media transporting line through a filter media inlet formed at the filter media layer; a pollutants desorption device disturbing the filter media layer polluted water in which the filter media and the pollutants are mixed transported by the filter media suction means to separate the pollutants from the filter media; and a filter media recharging port through which the filter media layer polluted water in a state where the pollutants and the filter media are separated is reintroduced into the filter media layer. According to the pollutants desorption filter media circulation device of the present invention, the device can increase backwashing efficiency to clean filter media with minimal cleaning water. Therefore, filter media cleaning is possible only with treated water in the nonpoint pollution reduction facility, whereby the device is economically favorable in construction and maintenance without having a separate treated water tank or backwashing water supply lines.
