| 摘 要： | 依托甪直污水处理厂再生水回用工程,研究利用浸没式超滤膜处理热电厂冷却水回用作为印染工艺漂洗用水的可行性以及采用混凝沉淀预处理对超滤膜污染的影响。结果表明:①采用浸没式超滤膜处理电厂冷却水,对浊度、总铁和COD的平均去除率分别为98.2%、96.9%和43.2%,出水水质稳定,能够满足印染企业漂染用回用水的水质要求;②增加混凝沉淀的预处理程序,对水体中污染物有很好的去除效果,能减缓超滤膜表面的不可逆污染,减少超滤膜的化学清洗次数,改善超滤膜的过滤性能,提高超滤膜的过滤通量。

| Abstract: | A water reclamation project was carried out in the Luzhi Wastewater Treatment Plant to stuuy me feasibility of treatment of cogeneration plant cooling water by submerged uhrafihration membranes for the reuse of dyeing water and the influence of coagulating sedimentation pre-proeessing on the ultrafiltration membrane pollution. The results show the following： （a） The removal rates of turbidity, total iron, and COD were 98.2% , 96.9%, and 43.2%, respectively, and the effluent of the submerged uhrafiltration membrane met the water quality requirements for the reuse of dyeing water. （b） Coagulating sedimentation pre-processing can effectively remove the pollutants in the water. It can alleviate the irreversible pollution on the surface of the ultrafiltration membrane, reduce the frequency of chemical cleaning, improve the filtration performance, and increase the filtration flux of the uhrafihration membrane. |
