Abstract:

The running principle of CAST technology and the treatment ways and manner according to different water quantity and quality are briefly described.The treatment result in Huiyang Wastewater Treatment Plant demonstrates that this process is feasible. The treated effluent water quality reaches the First Class Standard of the Pollutant Discharge in the Town Wastewater Treatment Plants（GB 18918—2002）.The removal rates of COD，BOD₅ and TP are 86%，93% and 85% respectively.

Key words: cyclic activated sludge technology, domestic wastewater, water quality
