Abstract: The authors carried out the experiment research on treatment of municipal wastewater by hybrid biological reactor in order to improve its treatment efficiency and reduce its run cost. According to the experiment, the authors brought up the optimum parameter for run from detention time, organic loading and gas water ratio three aspects. The results showed that took this method can guarantee the rate of COD degradation more than 80%, under the condition that organic loading is 2.44 kg COD/kg MLSS·d; Detention time is 1.5~2 h; The ratio of gas to water is (2.5~3)∶1. This method can intensify the phase transfer efficiency.

Key words: hybrid biological reactor, municipal wastewater, mass transfer
