Zusammenfassung:The present invention relates to an impurity separation-type apparatus and method for treatment of organic waste, capable of facilitating a concentration function of a membrane filtration device and a dehydration function of a dehydrator by removing various types of impurities contained in organic waste. To this end, provided is an organic waste treatment apparatus which is configured to allow organic waste to be fermented in an acid fermentation tank (100) and a methane fermentation tank (110). The organic waste treatment apparatus comprises: a first screen (120) which is connected to the methane fermentation tank (110) and separates coarse impurities (200) of a predetermined size or more from a methane fermentation liquid; a sludge storage tank (130) which is connected to the first screen (120) and stores the separated methane fermentation liquid; a second screen (150) which is connected to the sludge storage tank (130) and separates fine impurities (210) of a size smaller than the predetermined size from a sludge retention liquid; and a dehydrator (140) which is connected to the sludge storage tank (130) dehydrates the separated sludge retention liquid and discharges the dehydrated product as a sludge cake (220) and a filtrate. 본 발명은 유기성 폐기물 내에 포함된 다양한 협잡물을 제거하여 막여과장치의 농축작용 및 탈수기의 탈수작용을 원활하게 하는 협잡물 분리형 유기성 폐기물 처리장치 및 처리방법에 관한 것이다. 이를 위해, 산발효조(100)와 메탄발효조(110)에서 유기성 폐기물이 발효되도록 하는 유기성 폐기물 처리장치에 있어서, 메탄발효조(110)와 연결되어, 메탄발효액으로부터 소정 크기 이상의 조대협잡물(200)을 분리하는 제 1 스크린(120); 제 1 스크린(120)과 연결되고, 분리된 메탄발효액을 저장하는 슬러지 저류조(130); 슬러지 저류조(130)와 연결되어, 슬러지 저류액으로부터 소정 크기 보다 작은 미세협잡물(210)을 분리하는 제 2 스크린(150); 및 슬러지 저류조(130)와 연결되고, 분리된 슬러지 저류액을 탈수하여 슬러지 케이크(220)와 여액으로 배출하는 탈수기(140);를 포함하는 것을 특징으로 하는 협잡물 분리형 유기성 폐기물 처리장치가 제공된다.
