| 摘 要： | [目的]研究聚乙烯醇微滤膜应用于处理微污染原水的可行性。[方法]考察直接微滤与混凝-微滤组合工艺2种方式对微污染原水处理效果的影响,并对膜清洗方式进行探讨。[结果]混凝-微滤组合工艺在改善水质与缓解膜污染方面均优于直接微滤,出水水质中浊度、有机物、氨氮去除率分别为98.1%、86.1%与67.5%。[结论]混凝作为预处理可有效改善膜的过滤性能,提高有机物的去除效果。混凝-微滤组合工艺具有很好的推广价值。

| Abstract: | [Objective] The feasibility of the treatment of micro-polluted water based on polyvinyl alcohol(PVA) membrane was studied.[Method] The effects of the treatment of micro-polluted water using the direct microfiltration process and coagulation/microfiltration process were investigated,and the cleaning methods of the membrane were discussed.[Result] The coagulation/microfiltration process was more effective than the direct microfiltration process both in improving treated water quality and reducing membrane fou... |
