在生物反应器填埋场厌氧填埋实验研究的基础上,进行了垃圾降解的地球化学过程分析,建立了受地球化学因子影响,反映生物反应器填埋场水质变化的COD、VFA、及NH_4~+-N浓度变化的动态模型.研究表明:该模型拟合值与实测值吻合较好,能较好地预测垃圾填埋降解过程中水质的变化,为填埋场的渗滤液处理和水质污染控制提供理论依据.“,”Geochemical process of degradation of waste was analyzed,dynamic models on the variation of the concentrations of COD,VFA and NH_4~+-N,which reflect the variation of water quality in bioreactor landfill,were established based on experimental studies of anaerobic bioreactor landfill.The results showed that the fitted values calculated by the kinetic model agree well with the measured values,which can predict the variation of water quality during degradation of waste,thus providing the theoretic basis for leachate treatment and pollution controlling of water quality.
