洗浴废水超滤膜处理回用技术研究

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。

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

By use of ultra-filtration membrane in bathing wastewater reusing, this paper put forward acombined treatment process, which contained slight flocculation fiber filtration and ultra- filtration. Notonly were experiments on the main ccntamentation index of original water CODcr, turbidity and the removing performance of anion detergent LAS carried out, but also control methods of membrane pollutionwere provided in this study. The test results showed that when the flocculant dosage of aluminum sul-phate 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, simpleprocess and easy operation management etc. This new process provided a new important method for dualwater recycling by membrane technology. It is suitbale especially for hotel bathing wastewater reusing.
