Abstract

Abstract: According to the properties of Shibeiling landfill leachate, a two-phase anaerobic system composed of UBF acidification reactor with highly efficient biology ceramsite filter and UASB mechanization reactor was used to treat the leachate. The experiment results showed that when influent COD_Cr and BOD₅ concentration were 3 887 mg/L and 819 mg/L respectively, the HRT of the UBF and UASB was control at 10.3 h and 61.7 h respectively; the total removal rate of COD_Cr and BOD₅ was 85.4% and 90.1% respectively, the acidogenic-rate of UBF was about 42.9% and the ratio of BOD₅/COD_Cr was increased from 0.21 to 0.39.

Key words: landfill leachate, UBF, UASB, two-phase anaerobic, acidogenic-rate
