Aerobic granular sludge treatment system

The utility model discloses an aerobic granular sludge treatment system and belongs to the field of water treatment equipment. Sludge with small particle size in granular sludge can suspend on the upper layer of the device through high-speed rotation of the swirler, the sludge and upper-layer liquid are discharged together through the water outlet pipe, sludge with large particle size on the lower layer is discharged through the bottom sludge discharge port, and sorting of the aerobic granular sludge is achieved. 本实用新型一种好氧颗粒污泥处理系统，属于水处理设备领域；通过旋流器高速旋转，可将颗粒污泥中粒径较小的污泥悬浮在装置上层，通过出水管与上层液体一起排除，则下层颗粒较大的污泥通过底部排泥口排水，实现好氧颗粒污泥的分选。
