【摘要】 对以受污染河水为原水的反渗透系统膜污染问题进行了分析,初步认定反渗透膜污染是以生物粘泥、铁的氧化物及有机物为主的综合污染,而预处理的不完善、清洗方案选择不合理以及杀菌措施不够是导致膜污染的主要原因,最后提出了相应的解决办法。更多还原

【Abstract】 The membrane fouling of reverse osmosis system for treatment of polluted river water was analyzed. The membrane fouling is considered mainly caused by biological slime, iron oxide and organics, which is a synthesis fouling. The fouling reasons are the deficient pretreatment, the unreasonable choice of cleaning methods as well as the inadequate disinfection. In the end, the solving methods to the membrane fouling are proposed.更多还原
