超滤膜在污水回用过程中清洗的方法

Study on Ultrafiltration Membrane Cleaning Process in Wastewater Reuse.

在用超滤膜处理纪庄子污水厂二级出水试验的基础上 ,利用高浓度盐水对膜表面形成的胶体层和凝胶层进行清洗 。

Based on the experiment of secondary effluent reuse by ultrafiltration ,the paper presented a cleaning process of removing membrane colloid layer and gel layer with high concentration salt-solution which had a good effect.
