Abstract Taking a comprehensive waste landfill in Shanghai as the research object, the municipal solid waste samples were drilled for testing of biochemical degradation index. The results showed that the waste in the testing area has begun to produce methane stably, and it entered the slow degradation stage. Among them, the C/L(the ratio of cellulose and lignin) values of solid waste samples range from 0.72 and 1.53; pH values of leachate were between 7.91 to 8.92; BOD values were between 1050 and 5780mg/L, COD values were between 2640 and 15200mg/L, NH₃-N values were between 2110~4360 mg/L. The normalized indexes β₁, β₂, and β₃ for solid, liquid and gas phases were introduced to evaluate the degradation stage of the landfill. Among them, β₁ values were between 0.56 and 0.83; β₂ values were between 0.65 and 0.76; β₃ values were between 0.97 and 1.02. β₁ and β₂ could be used as the indicators determining the degradation stage of landfill, but β₃ could only be used to determine whether it is in the stable methane production stage. In addition, the calculation method of leachate production considering the coupling effect of compression and seepage was established. The leachate production rate from waste was around 70%~80%. The landfill gas production was calculated using the two-stage degradation model. As the waste stops landfilling, the landfill gas production rapidly decreased, and it would drop to 3.88% of the peak value by 2025 and would reduce to 0.08% of the peak value by 2040.

Key words： landfill biochemical degradation index of solid liquid and gas leachate generation rate gas production rate
