Automatic backwashing system for non-point pollution abatement facilities with automatic backwash and stagnation water treatment
Provided is an automatic backwashing apparatus for a non-point pollution abatement facility with automatic backwashing and stagnation water treatment functions, comprising: a pre-treatment chamber which treats for complete purification, which specifically has a wastewater chamber on the bottom to maximize backwashing efficiency by automatic backwashing and stagnation water treatment after purification, which circulates initial rainwater let in by a floc-forming barrel, which forms a great particle of floc by collision between foreign substances included in the initial rainwater, and which performs overflow and precipitates pollutants; a filtering chamber into which the water, from which pollutants are removed from the pre-treatment chamber, is let, and in which pollutants are filtered out by a filtering unit which comprises floating media in between filtering nets formed on the top and bottom; a cleaning/filtering water chamber in which the water purified by the filtering chamber overflows and from which the water is discharged through an outlet; and a backwashing processing unit which, when the purification process in the filtering chamber or rain is ended or when floating media is intended to be cleaned, automatically cleans the floating media by a set value and treats the stagnated water. Accordingly, the present invention can more efficiently purify a non-point pollution abatement facility when a user intends to reuse the facility.
비점오염물질을 깨끗하게 정화되도록 처리함은 물론 특히 정화 후 자동 역세척과 정체수 처리로 인한 역세척 효율성을 극대화할 수 있도록 하부에 퇴수조가 형성되며, 플록 형성 배럴(barrel)에 의해 유입되는 초기우수를 선회시켜 그 초기우수에 포함된 이물질 간의 충돌로 큰 입자의 플록(floc) 형태로 형성한 후 월류 되면서 오염물질이 침전되는 전처리조; 상기 전처리조를 거쳐 오염물질이 제거된 물이 유입된 후 상하부에 형성된 각 여과망 사이에 부상여재를 포함한 여과부에 의해 오염물질이 여과되는 여과조; 상기 여과조를 거쳐 정화된 물이 월류된 후 유출구를 통하여 유출되는 세정여과수조;를 포함하되, 상기 여과조에 정화 과정 또는 비가 종료되거나 부상여재를 세척하고자 할 때, 설정된 값에 의해 자동으로 부상여재를 세척 후 정체수를 처리하는 역세척 처리부;를 더 포함하는 자동 역세척 및 정체수 처리 기능을 갖는 비점오염 저감시설 및 그 자동 역세척장치를 제공한다. 그에 따라 비점오염 저감시설을 다시 사용하고자 할 때 더욱더 효율적으로 정화시킬 수 있는 효과를 가진다.
