The aim of the experiment was to enhance biodegradation and methane production of municipal solid waste (MSW). Two groups of simulated anaerobic bioreactor landfill were used; one group of mixed MSW with three bioreactors (R1, R2 and R3) and second group was compostable MSW with two bioreactors (R4 and R5). The different combinations of operational parameters were aeration with addition of aerobic microbial culture, anaerobic sludge, coarse gravel mixing, intermediate soil cover and varied leachate recirculation rate. The results observed at the end of 270days prevail that the process combination of above operational parameters adopted in compostable MSW bioreactor was more efficient approach for stabilization of MSW. It has accelerated the methane production rate (141.28Lkg(-1)dry waste) by 25%. It was also observed that the degradation time of MSW was reduced by 25% compared to maximum values quoted in the literature. The nonlinear regression of the cumulative biogas production and digestion time shows that Gompertz growth equation fits the results well.
本实验旨在提高城市固体废物（MSW）的生物降解和甲烷生成效率。使用了两组模拟厌氧生物反应器垃圾填埋场；一组是混合了三种生物反应器（R1、R2 和 R3）的混合 MSW，另一组是可堆肥 MSW 与两个生物反应器（R4 和 R5）。采用了不同的操作参数组合，包括曝气、添加好氧微生物培养物、粗砾石混合、中间土壤覆盖和不同的渗滤液再循环率。在 270 天结束时观察到的结果表明，可堆肥 MSW 生物反应器中采用的上述操作参数的组合是稳定 MSW 的更有效方法。它将甲烷生成率（141.28Lkg(-1)干废物）提高了 25%。与文献中报道的最大值相比，还观察到 MSW 的降解时间减少了 25%。累积沼气产量和消化时间的非线性回归表明，Gompertz 生长方程很好地拟合了结果。
