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.
