| 摘 要： | 用不同孔径的系列滤膜对上海市废弃物老港处置场的新鲜渗滤液、1991年垃圾产生的渗滤液进行了梯度分离，研究了COD、浊度的变化趋势以及紫外可见光吸光度与不同孔径膜之间的关系。结果表明：经过膜的梯度分离后，出水的COD值、浊度整体上呈降低趋势．但降低程度不等，膜材质和孔径对梯度分离有少许干扰；对各膜过滤后的出水进行紫外可见光扫描所得的曲线形状基本一致，但吸收峰向紫外区偏移。

| Abstract: | The colloidal particles present in two types of leachates, i.e., the raw leachate sampled from the landfill compartment under placement operation and aged leachate sampled from the landfill compartment closed in 1991, are separated by a series of membranes with varied porosity. Some parameters of the leachate before and after gradient separation by the membrane are determined and quantitatively co-related to the membrane porosity, such as COD, turbidity and the Ultraviolet-Visible absorbance. The result shows that the values of COD, turbidity decreased in the leachate after membrane separation, while the percent removals vary with the parameters observed; the Ultraviolet-visible absorbance curves of the leachate are similar in shape, while the absorption peaks shift to the far-ultraviolet region. |
