Abstract

본 발명은 폐수처리장에서 폐수를 정화하는 장치에 관한 것으로 기존 침전조 형태에 수질개량 장치를 부가하여 방류수의 수질을 현저히 개량하는 폐수처리장 침전조 수질개량 장치에 관한 것이다.The present invention relates to an apparatus for purifying wastewater in a wastewater treatment plant, and a sewage treatment plant for improving the quality of effluent water by adding a water quality improving apparatus to an existing sedimentation tank form.

기존 침전조의 경우 오염물질이 침전하지 않고 침전조 이후로 월류 되기도 하여 활성슬러지법의 경우 충격부하나 슬러지 벌킹(Sludge Bulking), 슬러지 부상(Sludge Rising), 플록(Fioc) 해체 현상등이 발생하면 처리되지 않은 혼탁폐수가 그대로 방류되어 수질을 악화시키는 문제점이 있었으므로 기존 침전조 형태에 적은 비용과 우수한 오염물질 제거효율을 갖도록 침전조 수질개량 장치를 고안한 것이다.In the case of existing sedimentation tanks, pollutants do not settle and are overflowed after the sedimentation tank.In case of activated sludge method, impact load, sludge bulking, sludge rising, and dissolution of flocs are not processed. Since there was a problem of deterioration of the water quality since the untreated turbid wastewater was discharged as it is, the sedimentation tank water quality improvement device was designed to have low cost and excellent pollutant removal efficiency in the existing sedimentation tank form.

이렇게 안출된 본 발명은 폭기조에서 산소가 소비되어 부족한 용존 산소 상태로 침전조로 유입되는 폐수의 슬러지부상(Sludge Rising)을 방지하며 오염물질 제거를 위해 필요한 산소를 미생물에 충분한 용존산소(D0) 공급을 위해 에어관(2)을 설치하여 정류관(3) 내부로 폐수유입과 함께 공급하며 유입된 폐수는 충분한 폐류시간을 가지면서 침전조에서 오염물질이 분리가 되어 슬러지는 탈수기로 보내어 처리하고 상등수는 여재(1)를 통과하면서 여재(1)에 의한 여과에 의해 미세입자까지 걸러지고 여재(1)에 부착되어 성장한 미생물에 의해 오염물질이 최대한 분해되므로 충격부하나 슬러지벌킹(Sludge Bulking), 슬러지부상(Sludge Rising), 플록(Fioc) 해체 현상이 발생하더라도 방류수에서 필요한 깨끗한 처리수를 얻을 수 있도록 구성되어 있다.In this way, the present invention prevents sludge rise of the wastewater flowing into the sedimentation tank with insufficient dissolved oxygen in the aeration tank and provides sufficient dissolved oxygen (D0) supply to the microorganisms with oxygen necessary to remove contaminants. Hazardous air pipes (2) are installed and supplied together with the wastewater inflow into the rectifier pipe (3). The inflowed wastewater has sufficient wasteflow time and the contaminants are separated from the sedimentation tank and sent to the dehydrator for sludge treatment. 1) Through the filtration by the filter medium (1) to filter out the fine particles and contaminants are decomposed as much as possible by the microorganisms attached to the filter medium (1), so as to impact impact, sludge bulking, sludge wound (Sludge) Rising) and Floc (Fioc) Disassembly occurs even if the effluent is clean.

Description
