| 摘 要： | 用系列滤膜对老港填埋场2003年3月份新鲜渗滤液进行了梯度分离．并研究了其CODcr、氨氮、TOC、IC、TC、TS、FS、电导率、pH、色度，浊度的变化趋势与不同孔径膜之间的关系。结果表明，随着膜孔径的减小，CODcr、氨氮、TOC、IC、TC、TS、FS、色度、浊度等都有不同程度的降低，但降低不大，说明可溶性部分物质对新鲜渗滤液的污染性贡献最大；电导率、pH则先增大后减小。

| Abstract: | The colloidal particles present in the raw leachate sampled from the Laogang landfill compartment under placement operation in March 2003 are gradiently separated by a series of membranes with varied porosity. COD\-\{Cr\}, ammonia\|N, conductivity, pH, TOC, IC, TC, FS(fixed solid), TS, colourity, turbidity in the leachate before and after gradient separation by the membrane are determined and quantitatively co\|related to the membrane porosity. It is found that the values of the parameters, such as COD\-\{Cr\}, ammonia\|N, TOC, IC, TC, FS, TS, colourity, turbidity decreased after membrane separation, which indicate that the dissolved fraction have a significant impact on the contamination of the raw leacheate, while conductivity and pH increased at first and then decreased. |
