The concentrations of CODcr and NH4+ vary from low to high, then from high to low in the process of refuse leaching, that is to say that there are three phases which are aerobian decomposition, facultative aerobian and anaerobian decomposition;(3)The time of landfill reaching to stabilize under the condition of filtration, for landfill of Jinqianpu, is at least 86 years if CODcr is regarded as a index; but is about 98 years when NH4+ as an index;(4)The column leaching experiment simulated is carried on interactivity between leachate and different lithologic characters, water-bearing media of different thickness. Some parameters can be determined by calculation, such as, the retained factor and hydro-chemical transportation rate of pollutants in suspended media, which quantitatively analyse the suspended soil capability of components purification and the pollution scope of water bearing media.
