Summary:The present invention relates to an apparatus for separating a solid-liquid using micro-bubbles. More particularly, the apparatus includes a water storage tank having a water storage space part having an inner upper portion, which is open, to contain raw water, a raw water supplying unit to supply the raw water to the water storage space part of the water storage tank, a concentration discharge unit to discharge micro-particles, which are lifted, of the raw water contained in the water storage tank, a treated-water discharge unit to discharge treated water, which is separated from the micro-particles, of the raw water of the water storage tank, a micro-bubble supplying unit to generate the micro-bubbles using the treated water of the water storage tank and to supply the micro-bubbles to the water storage supplying unit, and a scraping unit positioned at an upper portion of the water storage tank to move the lifted sludge to the concentration discharge unit and to separate and discharge the lifted sludge by a scrapper. As described, according to the present invention, the supplied micro-bubbles are mixed with the raw water to improve the efficiency of separating the sludge, and the separated sludge is separately discharged, thereby improving working efficiency. 본 발명은 미세기포를 이용한 고액분리장치에 관한 것으로, 더욱 상세하게는 내부에 상측으로 개방되어 원수가 담겨지기 위한 저수공간부를 갖는 저수탱크, 상기 저수탱크의 저수공간부로 원수를 공급하기 위한 원수공급부, 상기 저수탱크의 원수 중 부상된 미세입자가 배출되기 위한 농축액배출부, 상기 저수탱크의 원수 중 미세입자와 분리된 처리수가 배출되기 위한 처리수배출부, 상기 저수탱크의 처리수를 이용하여 미세기포를 발생시켜 저수공간부로 공급하는 미세기포공급부, 및 상기 저수탱크의 상측에 위치되되, 이동되는 스크레이퍼에 의해 부상된 슬러지를 상기 농축액배출부로 이동시켜 분리 배출시키는 스크레이핑부,를 포함한다. 상기와 같은 본 발명에 의하면, 공급되는 미세기포를 원수와 혼합시켜 슬러지 분리효율을 향상시키고, 분리된 슬러지를 별도로 배출시킬 수 있어 작업 효율을 향상시킬 수 있다.
