| 摘 要： | 考察了采用混凝-超滤法处理低温低浊时期松花江水的中试试验效果,并与水厂常规处理水质进行了比较.试验结果表明:混凝-超滤法出水浊度恒低于0.3 NTU;投加20 mg/L聚合氯化铝,超滤膜对CODMn去除率达到50%~58%,膜出水色度为6~8度;此外,投加混凝剂可以使膜渗透性能得以改善.因此混凝-超滤法可以作为低温低浊水处理的有效方法. |

| Abstract: | The water treatment of Songhua River in the period of low temperature and low turbidity water was investigated by coagulation- UF process in pilot equipment, and the water quality treated by the process was compared with the traditional disposal water. The experimental results showed that in coagulation - UF process, the turbidity of outlet effluent was below 0.3 NTU; the removal rate of CODMn was 50% -58% and the outlet effluent color was 6- 8 by using coagulant concentration of 20 mg/L polyaluminium chloride. Furthermore, membrane permeability was improved with the addition of coagulant. Therefore, coagulation - UF process is an effective technique for treating low temperature water with low turbidity. |
| Keywords: | low temperature and low turbidity water ultrafiltration coagulation organics turbidity membrane flux |
