Abstract

Abstract: The experimental research about application of catalytic oxidation in sight water resumption has been carried out through our own test device. The slight water to be disposed has low organic capacity with large range of water quality and the concentration of COD_Cris in the range of 25-35 mg/L and 2.2-3 mg/L for NH₃-N and 0.55-0.85 mg/L for TP respectively. The experimental results show that at the suitable operating conditions biological catalytic oxidation could lower the concentration of COD_Cr, NH₃-N and TP to be 14.62 mg/L,0.26 mg/L,0.19 mg/L respectively to high extent, which is lower than the standard of Ⅲ class water quality and can meet the need of sight water.

Key words: biological catalytic oxidation, sight water, optimal aeration quantity, optimal water power standing time, optimal gaswater ratio
