[Bio-contact oxidation A/O process experiment on Guanting Reservior water].
The results of the experiments showed that biological contact A/O process had evident removal effect of contaminations such as COD, ammonia nitrogen in water entering into Guanting Reservior and could successfully resume the quality. Under the conditions that air supply flux(gas/ammonia nitrogen) was more than 0.1 L/mg and influent ammonia nitrogen loading was lower than 0.08 kg/(m3.d), effluent COD was steadily 30 mg/L around, ammonia nitrogen removal rate was higher than 60%, and TN removal rate was 1.0%-31.3%. The main control parameter was influent ammonia nitrogen loading, which was proposed to be lower than 0.08 kg/(m3.d).
