| 摘 要： | 利用高效液相色谱法、三维荧光光谱法分析,考察以膜分离为主的物化处理方式对城市污水中各污染因子的去除特性,尤其对溶解性有机物的富集特性.结果表明,经以膜分离为主的物化方式处理后的城市生活污水属于低碳氮比废水;微絮凝过滤主要富集的是原水中非溶解性有机物和相对分子质量大于30 000的芳香类蛋白物质,富集程度在60. 93%,尤其是类酪氨酸和类色氨酸; 0. 45μm和0. 22μm醋酸纤维膜能将相对分子质量大于30 000的溶解性有机物全部富集,但是微滤膜对有机物的富集没有选择性;纳滤主要对城市污水中的富里酸类物质和腐殖酸类物质有很好富集效果,富集程度分别为52. 01%和53. 57%,溶解性有机物的总体富集程度在42%左右.
