复合膜反渗透装置微生物污染的防治

简述了反渗透（ＲＯ）装置被微生物污染的情况及其危害．提出了防治复合膜反渗透装置微生物污染的方法，包括：ＲＯ前的预处理工艺的选择，采用紫外线杀菌器及电子除菌器；ＲＯ膜阻垢剂及抑菌剂的选择；ＲＯ系统停运时防止微生物污染的方法；ＲＯ系统被微生物污染后用杀菌剂药液清洗ＲＯ膜及系统．

Prevention and clearing of microorganism fouling to composite membrane of RO apparatus

This article briefly introduced the microorganism fouling problem,including its symptom and harm.It also provided the methods which can be used to prevent RO from being fouled by microorganism,such as the selection of pretreatment technique before RO system,the application of UV or electronic sterilizer, the choice of composite membrane antiscale and bacteriostat, the way to prevent from being fouled by microorganism during the period of RO system offline and the detailed cleaning method of RO system with steriling agent when it is fouled by microorganism.
