微絮凝过滤工艺在机场雨水中水回用中的试验研究

Study on the Experiment of Micro-Flocculation and Filtration Used in Recycled Water Utrilization with Rainwater

雨水回用是一种有效的解决水资源缺乏的方法。以上海浦东国际机场围场河收集的雨水作为中水水源。考察了微絮凝过滤工艺对雨水中的浑浊度、UV254、氨氮(NH3-N)以及氯离子(Cl-)的去除效果;同时对比了氯化铁(FeCl3)和聚合氯化铝(PAC)两种絮凝剂对机场雨水的处理效果,获得了不同絮凝剂条件下的可利用的微絮凝过滤工艺设计和运行参数。

Rain water utilization is one of the effective measures for resolving more and more insufficient water resources. The rain water from Pudong International Airport area was selected as source water of reclaimed water. The removal effect of turbidity, UV~, NH3-N and C1- in raw water were investigated and compared based on adding two different coagulants such as ferric chloride （FeC13） and poly aluminum chloride （PAC）. Finally, the optimal design parameters of process combination with micro-flocculation and filtration were obtained.
