1. Experimental purpose:

The cycle cycle activity sludge method (CYCLIC Activated Sludge System (CASS) is developed on the basis of Iceas's process. It is an improved type of SBR process. One cycle is composed of the following stages: filling water / aeration, filling / precipitation, skimming, idle. This process is a circular intermittent sewage treatment process with a nitrogen -dehydration and phosphorus removal effect. It has the advantages of traditional SBR treatment technology. At the same time, it can effectively inhibit the expansion of silk -like bacteria. Teaching demonstration and dynamic experimental equipment for process. Through the hope of this experiment, the following goals are achieved:
