| 摘 要： | 实验对已污染的聚醚砜膜进行了清洗的研究,并通过测量各种清洗剂清洗后膜水通量的恢复,确定适宜的清洗剂、清洗时间、清洗液浓度和操作压力,选择出最佳的清洗方案,取得较好的清洗效果。通过研究表明:被污染的聚醚砜膜用混合清洗剂清洗恢复率可达到85%,效果要明显优于单一的清洗方法。

| Abstract: | In situ cleaning of polluted PES membranes used in a membrane bioreactor was examined. By examining the water flux recovery of PES membranes,the appropriate rinse agent and its concentration,the cleaning time,the working pressure and the best cleaning strategy were confirmed to clean polluted PES membranes. An optimized cleaning efficiency of 85% was observed when using NaOH and NaClO as complex rinse agent. |
