| 摘 要： | 采用地表水的反渗透系统,经过混凝处理后外观清澈,经砂滤和活性炭过滤后浊度接近0.1 NTU,但污染指数(SD I)仍然在4以上,投运反渗透会导致产水量随时间的增加而递减速度加快,需要高压泵升压维持产水量,使反渗透膜寿命降低。本文就这一问题进行分析并提出了可行的解决方案。

| Abstract: | The ground water with RO pretreatment will be fair clear after coagulation,the turbidity of the ground water is about 0.1 NTU after filtration with mechanical filter and active carbon,but the SDI of the ground water is still in excess of 4,if the RO pretreatment is run,the permeate flux will increase,but the increasing rate will decline with time.The useful time of the RO membrane will reduce,if the permeate flux is maintained with high pressure pump.This article gives the analysis and the solution for the ... |
