The present invention relates to an aerobic granular sludge sorter, which comprises: a discharging means to discharge a reaction liquid inside a biological treatment reaction tank; a filtration means which is connected to the discharging means and separates the reaction liquid into anaerobic granular sludge and fine sludge having particle sizes smaller than the anaerobic granular sludge by filtering the reaction liquid discharged by the discharging means; and a returning means which connects the filtering means to the biological treatment reaction tank and returns the anaerobic granular sludge separated by the filtering means to the biological treatment reaction tank. 본 발명에 따른 호기성 그래뉼 슬러지 선별장치는, 생물학적 처리반응조 내의 반응액을 배출하는 배출수단; 상기 배출수단과 연계되어, 상기 배출수단에 의해 배출된 반응액을 필터링하여 반응액에 포함된 호기성 그래뉼 슬러지와 상기 호기성 그래뉼 슬러지보다 입자크기가 작은 미세슬러지를 분리하는 필터링수단; 및 상기 필터링수단과 생물학적 처리반응조를 연계하여, 상기 필터링수단에 의해 분리된 상기 호기성 그래뉼 슬러지를 상기 생물학적 처리반응조 내에 리턴시키는 리턴수단;을 포함한다.
