Abstract:

The research on domestic sewage disposal by CAST is showed in this paper. The primary source of domestic sewage is offices and living quarters. The operation results show that the process has the advantage of stable operation, stronger resistance to shock loading, high efficiency of biological phosphorus removal and the low operation cost. The effluent is reaching the first class of Integrated Wastewater Discharge Standard (GB8978-1996) and the Design Criterion of Wastewater Recycling Engineering(GB50335-2002).

Key words: CAST, Domestic Sewage, biological phosphorus removal, simultaneous nitrification and denitrification
