| 摘 要： | 通过对低压膜过滤和传统滤池过滤的滤后水水质和运行成本的比较分析，得出低压膜过滤在低温低浊水时可以取代滤池过滤的结论，低压膜过滤在保证出水浊度低于l NTU时，滤速可达20m／h，过滤周期为150h，低压膜过滤可以采用原水直接过滤，不需投加混凝剂，长期运行后没有受到较大的污染．反冲洗方式简单易行，所需压力远低于常规的膜组件．

| Abstract: | It is concluded from the comparison and analysis of filtrated water quality and running cost between direct filtration using low pressure membrane and traditional filter filtration that direct filtration using low pressure membrane can replace filter filtration with better economic and social effects when the temperature and turbidity of raw water is lower. With the turbidity of treated water below 1 NTU, the filtration speed can go up to 20 m/h,and the filtration duration can be 150 hours. The raw water can be filtrated by membrane equipment without coagulant, and in addition, the membrane is not contaminated seriously after running a long period. The process of backwash-ing is easy and practical and the pressure needed is far lower than regular membrane module. |
