混凝和活性炭联用对有机物质的去除效果

Removal effect of organic substances with the joint of coagulation and PAC

研究了混凝和粉末活性炭对水中腐殖酸和苯酚的去除效果,选用聚合氯化铝作为混凝剂和粉末活性炭分别和联合使用时对水中腐殖酸和苯酚的去除效果进行了考察,结果表明:单独使用聚合氯化铝对苯酚的去除效果不佳,先投加活性炭后投加聚合氯化铝比两种同时投加时效果更好。

This paper studies the removal effect of coagulation and PAC for humic acid and phenol, surveys the removal effect of coagulation and PAC by respectively using poly aluminum chloride and PAC and by joint using poly aluminum chloride and PAC. Results show that： the removal effect of coagulation by singly using poly aluminum chloride is not so good, but the removal effect by first increasing PAC and then increasing po- ly aluminum chloride will be better than the removal effect by simultaneously inputting the two.
