FILTERING TYPE APPARATUS FOR TREATING NON-POINT CONTAMINANTS(FTA)

摘要

PURPOSE: A nonpoint pollution source filtering type processing unit is provided to improve the efficiency of filtration; and have the nonpoint pollution source filtering type processing unit which is convenient to clean and post manage by connecting multiple fiber unit filters to be separable. CONSTITUTION: A nonpoint pollution source filtering type processing unit comprises a precipitation tank (10); a partitioning plate (40); multiple impurities collecting tubes (20); and a fiber unit filter (30). The partitioning plate divides an internal space of the settling tank to the top and the lower part, and arranges as the horizontal direction. The multiple impurities collecting tubes are arranged to the top and bottom direction through the partitioning plate; and the fiber unit filter is inserted within the impurities collecting tube. The Multiple fiber unit filters are consecutively arranged by being adjacent to each other in the inside of the impurities collecting tube. The contaminant is filtered while the contaminated water is flowing through the impurities collecting tube; and the contaminated water is discharged to the settling tank outside after passing from the drain hole of the impurities collecting tube.
