Abstract

A method and a system for a continuous-flow aerobic granular sludge (AGS) process with improved two-stage sedimentation are provided. The method includes the following steps: arranging a biochemical reaction tank, a granular sludge sedimentation tank, and an inclined plate sedimentation tank that are connected sequentially, and arranging an inclined device in the inclined plate sedimentation tank; allowing sewage to continuously flow into the biochemical reaction tank, and allowing a sludge-water mixture obtained after a biochemical reaction to enter the granular sludge sedimentation tank, such that heavy sludge in the sludge-water mixture is quickly settled in the granular sludge sedimentation tank and returned to the biochemical reaction tank; and allowing light flocculent sludge in the sludge-water mixture to flow into the inclined plate sedimentation tank.
