AI Technical Summary
Technical Problem
Existing water treatment facilities struggle to efficiently remove contaminants, particularly BOD, nutrients, and pollutants from non-point source pollutants, leading to ecosystem disruption and eutrophication, and conventional cleaning methods are inadequate for curtain filters.
Method used
A water treatment facility with a coagulation tank, filtration tank, and filtration units comprising curtain and mesh filters, using coagulants like polyaluminum chloride, and a washing unit for forward and reverse cleaning to remove contaminants effectively.
Benefits of technology
The facility significantly reduces BOD, SS, TN, TP, and TOC, maintains filter efficiency, prevents clogging, and allows for easy maintenance by removing contaminants from curtain and mesh filters.

Abstract
The disclosed water treatment facility of the present disclosure comprises: a coagulation tank including a contaminated-water inlet and a coagulant inlet, and forming a floc; and a filtration tank into which contaminated water containing the floc flows from the coagulation tank, wherein the filtration tank can include: a central inlet part having a plurality of flowing-water holes formed therethrough along the circumferential portion; an inlet pipe extending from an open lower portion of the central inlet part so as to guide, into the filtration tank, the contaminated water containing the floc from the coagulation tank; a plurality of filtering parts arranged to be spaced from each other as concentric circles around the central inlet part so as to filter the contaminated water containing the floc; a support part which extends in an annular shape from the lower end portion of the central inlet part, and which has the filtering parts coupled to the top thereof; and a washing part which can be rotated around the center of the central inlet part, and which includes nozzles that spray washing water in the radial direction at the inner sides of the filtering parts so as to wash the filtering parts.
