Summary:The present invention relates to a water treatment system comprising: an organic acid generating tank in which influent water flows in, influent water and returned sludge generate organic acid through a biological reaction, and which discharges treated water containing organic acid; an SBR reaction tank connected to a rear end of the organic acid generating tank so that treated water discharged from the organic acid generating tank flows in, and repeatedly creating an anaerobic and aerobic environment to remove organic matter, phosphorus, and nitrogen contained in the treated water; and a dewatering unit collecting the sludge precipitated in the SBR reaction tank, dehydrating the collected sludge, and separating and discharging the dewatered filtrate and surplus sludge. The economic feasibility is further improved by significantly lowering the moisture content of sludge containing water, reducing sludge disposal costs to a minimum. Thus, the economic efficiency can be further maximized by making it very advantageous to recycle sludge solids as fuel. 본 발명은 유입수가 유입되고 유입된 유입수와 반송슬러지가 생물학적 반응을 통해 유기산을 생성하며 유기산을 포함하는 처리수를 배출하는 유기산생성조; 상기 유기산생성조의 후단에 연결되어 상기 유기산생성조로부터 배출되는 처리수가 유입되며 혐기 및 호기 환경을 반복 조성하여 처리수에 포함된 유기물, 인, 질소를 제거하는 SBR반응조; 상기 SBR반응조에서 침전된 슬러지를 수집하고 수집한 슬러지를 탈수처리하여 탈수여액과 잉여슬러지를 각각 분리 배출하는 탈수유닛;을 포함하는 것을 특징으로 하는 수처리 장치에 관한 것으로서, 수분이 함유된 슬러지의 수분 함유율을 현저하게 낮추면서 슬러지 폐기처리 비용을 최소한으로 줄여 경제성을 개선하면서 슬러지 고형물을 연료 등으로 재활용 하는데 매우 유리할 수 있도록 하여 경제성을 더욱 극대화하였다.
