海水淡化预处理中超滤膜污染机制及控制方法研究进展
Research on the Polluting Mechanisms and Control Methods of Ultrafiltration Membranes in Seawater Desalination Pretreatment
摘要
Abstract
As a crucial means to ensure the long-term stable operation of reverse osmosis technology in seawater de-salination,ultrafiltration pretreatment has become increasingly important.However,with the increasingly complex pollutant composition in seawater,the anti-pollution performance of the ultrafiltration membranes faces severe challenges.The frequent cleaning of membrane systems not only increases operation and maintenance costs but also restricts the further development of the process.Therefore,it has been an urgent need to develop new membrane components and processes that combine high anti-pollution performance,economy,and environmental friendliness.This paper focuses on the issue of ultrafiltration membrane pollution in seawater desalination scenarios.The relevant literature in recent years are summarized,and comprehensively expounded from four dimensions of pollution types(inorganic,organic,biological pollution),pollution mechanisms(hole shrinkage,holeclogging,filter cake forma-tion),key influencing factors(water quality parameters,operating conditions,membrane materials,etc.)and main-stream control methods(pretreatment,membrane material modification,operating parameter regulation,etc.)in or-der to provide a systematic reference for theoretical research and practical engineering applications of ultrafiltration membrane pollution control.关键词
