| 摘 要： | 研究表明，混凝去降分子量〉４０００ｕ的溶解性有机场（ＤＯＭ）效果较好，而对分子量〈４０００ｕ的去除效果较差。粉末活性炭去除低分子量的ＤＯＭ效果较好，去除大分子量的ＤＯＭ效果较差。当粉末活性炭投加量较大时，ＤＯＭ分子量的大小对吸附效果的影响减少。黄浦江水中分子量〉４０００ｕ的一部分有机物难以被粉末活性炭吸附去除。

| Abstract: | A study on removal of DOM from source water of Huangpujiang River by coagulation and PAC process was carried out. The results showed that coagulation process was more effective in removing DOM with molecular weight higher than 4 000 u, but less effective in removing that with molecular weight lower than 4 000 u. PAC process was more effective in removing low molecular weight DOM, but less effective in removing high molecular weight DOM. The effect of molecular weight of DOM on adsorption was diminished when dosage of PAC was high. DOM in the Huangpujiang River with molecular weight lower than 4 000 u was difficult to be removed by PAC. |
