1. Experimental purpose:
Cyclic Activated Sludge System (CASS) is developed on the basis of ICEAS process. It is an improved version of SBR process. It combines biological reaction process and mud-water separation process in one pool. Each cycle consists of the following stages: filling/aeration, filling/sedimentation, skimming, and idle. This process is a cyclic intermittent sewage treatment process with nitrogen and phosphorus removal effects. It has the advantages of traditional SBR treatment process and can effectively inhibit the expansion of filamentous bacteria. It is a teaching demonstration and dynamic experimental equipment of "water inlet and outlet" activated sludge process. Through this experiment
