超滤因其处理高效、对有机物去除效果好等优点已广泛用于净水工艺,膜污染问题影响其长期运行稳定性,增加净水工艺运行维护成本。本文总结了超滤膜污染物质及成因,综述了预氧化处理技术,重点介绍了高锰酸钾、臭氧和次氯酸钠预氧化,以期为预氧化缓解超滤膜污染研究提供理论依据。Ultrafiltration has been widely used in the water purification process due to its high efficiency in treatment, good removal effect of organic matter, etc. Membrane contamination affects its long-term operational stability and increases the cost of operation and maintenance of the water purification process. The paper summarized the pollutants and causes of ultrafiltration membrane pollution, reviewed pre-oxidation treatment technologies, and focused on the pre-oxidation effects of potassium permanganate, ozone, and sodium hypochlorite. The objective is to provide a theoretical basis for the study on mitigating ultrafiltration membrane pollution through pre-oxidation.
