摘　　要：依据准好氧填埋和厌氧填埋的原理,构建了大型模拟填埋场,并定期对渗滤液水质进行监测分析。结果表明,准好氧填埋结构比厌氧填埋结构更有利于渗滤液中污染物的衰减,NH3N尤为明显;准好氧填埋结构渗滤液主要污染物浓度呈稳步下降规律,而厌氧填埋结构渗滤液水质在前期波动较大,NH3N在后期仍有较大幅度的变化。Two large scale landfilling installations were built according to semi-aerobic landfilling and anaerobic landfilling theories.The concentrations of COD_ Cr,BOD_5 and NH_3-N were detected regularly.The results showed that,the concentration of pollutants in leachate of semi-aerobic landfilling structure reduced more quickly than that in anaerobic landfilling structure.The pollutant concentrations in leachate of semi-aerobic landfilling structure reduced regularly,but which in aerobic landfilling leachate varied greatly in early period of experiment.
