For landfill of Jinqianpu, if peripheral zone of yard is consisted of mild clay the longest transportation distances of CODcr and NH4+ are 56.5m and 25.75m respectively in the time limit of landfill stabilization;(5)The optimal dilution ratio of groundwater runoff volume and leachate is 7:1 to meet more over Ⅲ groundwater quality standard(GB/T14848-93);(6)To build numerical model. Using CL- as a simulation factor, the expansion with time of pollution plume was simulatively calculated when the concentration of CL- is 5000mg/L and 2000mg/L in Jinqianpu landfill by means of internationally general simulating software FEFLOW.

就金钱堡填埋场而言，若场地周围为试验亚粘土层，则在填埋场稳定化年限内和的最大迁移距离分别为56.5m和25.75m；（5）垃圾渗滤液与地下水混合稀释后地下水能够达到III类水质标准以上的混合比为地下水径流量与垃圾渗滤液入渗量之比为7：1；（6）建立污染质运移的数值模型，以为模拟因子，利用国际上通用的模拟软件FEFLOW模拟计算了金钱堡垃圾填埋场中浓度分别为5000mg/L和2000mg/L时在一系列年份对地下水污染晕的扩展。
