摘要
论述了膜污染及其影响因素,通过测定运行过程中膜过滤压力的变化,研究了不排泥条件下水力停留时间对膜分离特性的影响,并分析了空曝气与化学清洗对减缓膜污染的效果,提出了膜污染控制的相关措施。
The membrane fouling and its effection are analysised, the pressure changes of the membrance filtering are measured, the effeetions of different HRT on membranee separation characteristics without discharging sludge are researched, the effections of empty aeration and chemistry cleaning on slowing down the membrane fouling are analysised, finally the controlling researchment of membrance fouling are point out.
