| 摘 要： | 试验研究了天然有机物(腐植酸、富里酸)对混凝除藻的影响,以及在含有天然有机物水体中混凝除藻的机理.结果表明,天然有机物会与藻细胞争夺絮凝剂,由于天然有机物与PAC亲和力强,PAC优先与天然有机物结合,再与藻细胞结合,当水体中天然有机物含量较多时,混凝除藻效果降低.当腐植酸质量浓度为20.2 mg/L时,藻去除率仅为2....

| Abstract: | The effect of natural organic matters(humic acid,fulvic acid) on algae removal by coagulation process was investigated and the mechanism thereof was also analyzed.The results of the test showed that: natural organic matter would compete against algae cells for flocculant.As natural organic matter had a strong affinity for PAC,it would be combined with PAC first,and then with algae cells;with the increase of nature organic matters in water,the algae-removal performance of coagulation process decreased.When t... |
