摘要
以废水回用为目的,研究了利用高效经济的纳滤膜处理含磷废水的工艺方法,系统地讨论了进料流量、操作压力等因素对过程的影响,得出了处理含磷废水的合适工艺条件:操作压力2.5～3.0MPa、进料流量572.6～608.7L/h,最终除磷率为23%,总盐截留率也可达到95%以上,达到了浓缩除杂的目的,符合工业生产的要求。
Technological methods for recovering the wastewater containing phosphate by the efficient and economical nanofiltration membrane process were studied in this article. The effects of nanofiltration membrane pressure and flow rate on the process were systematically studied. It was found that the optimal treatment conditions of wastewater containing phosphate were the following: nanofiltration membrane pressure 2.5～3.5MPa, flow 572.6～608.7 L/h. In this case, the total phosphate removal was 23%, the total salt rejection could also reach to above 95%. This process can concentrate and purify the wastewater containing phosphate and meet the requirements of the industrial production.
