Abstract

Hybrid anaerobic reactor(HAR), followed by biological contact oxidation(BC) technique, is used for treating domestic sewage. When HAR is under operation for 31 d and the water temperature is 15℃, the COD removal rate is up to over 60%. When outlet water is treated by biological contact oxidation, HRT is 3.2 h, the COD of outlet water is less than 40 mg/L averagely, SS less than 12 mg/L, BOD5 and NH3 less than 15 mg/L. The results show that HAR and BC techniques can be used for treating domestic sewage in areas where the climate is suitable.
