| 摘 要： | 针对反渗透技术回收电厂循环冷却水排污水工艺中给水pH值对反渗透运行效果的影响进行了研究。通过试验测试了给水pH值对反渗透系统膜通量及脱盐率等性能的影响,并通过实际运行考察了反渗透系统在不同给水pH值下对电厂循环冷却水排污水的处理效果。结果表明,反渗透的膜通量随给水pH值的增加而增加,当给水pH值>7.5后,反渗透系统可以达到较高的膜通量;而给水pH值在8.0～9.0之间时,各种离子的脱盐率处于最高水平。综合这两方面因素及运行效果分析,把反渗透给水pH值控制在7.5左右,可以获得最佳处理效果及最低能耗;对于高参数锅炉补给水处理,反渗透更具有常规离子交换处理方式难以比拟的优点。

| Abstract: | Research were carried out targeting the reverse osmosis effects of pH value of feed water of the circulating cooling sewage from power plants.The effects of feed water pH value on the membrane flux and rate of desalination of reverse osmosis system were tested in the experiment,and the results were investigated in the practical operation.The results show that the membrane flux increases as results of the increasing of the pH value of feed water.When the feed water pH value is larger than 7.5,the higher memb... |
