城市污水中有机污染物的分布

Distribution of organic pollutants in domestic wastewater

以城市污水为对象,以0.45μm滤膜,对水中污染物进行分类,利用高效液相色谱(HPLC)对污水中的溶解态有机物分子量分布进行分析,指出该采用的分析方法具有实用价值,研究结果可为城市污水处理工艺的选择提供依据。

In this paper,domestic wastewater was main objec t of study. A membrane filter with 0.45 μm pore size was used to separate the pol lutions. HPLC was applied to analysis the molecular weight distribution of solub le organic matter in domestic wastewater. The methods adopted in this paper are applicable in the field of wastewater treatment. The result of the study can pro vide theoretical basis for the selection of wastewater treatment method.
