洗浴废水超滤膜处理回用技术研究

Research on ultra-filtration membrane technology used in bathing wastewater reusing

将超滤膜技术用于洗浴废水处理回用，提出“微絮凝纤维过滤＋超滤”组合工艺，分别就试验工艺对原水中主要污染指标 CODCr、浊度、阴离子洗涤剂 LAS的去除性能进行了试验研究，并提出了膜污染的控制措施。试验结果表明，洗浴废水超滤组合工艺处理效果好，流程简单，占地面积小，易于操作管理。

： By use of ultra－ filtration membrane in bathing wastewater reusing, this paper put forward a combined treatment process, which contained slight flocculation fiber filtration and ultra－ filtration. Not only were experiments on the main contamentation index of original water CODCr， turbidity and the removing performance of anion detergent LAS carried out, but also control methods of membrane pollution were provided in this study. The test results showed that when the flocculant dosage of aluminum sulphate was 35～ 40mg/L， the fiber filter flow rate was 20m/h and the ultra－ filtration flux was 40L/(m2· h), combined treatment had many advantages such as high organic matter removal ratio, simple process and easy operation management etc. This new process provided a new important method for dual water recycling by membrane technology. It is suitbale especially for hotel bathing wastewater reusing.
