以中空纤维超滤膜技术为核心的组合工艺在水处理中的应用

Application of the combined process with the hollow fiber ultrafiltration membrane as core in water treatment

中空纤维超滤膜因单位体积有效膜面积大,填充密度高,操作压力低,能耗小,通量高,并能很好的进行反冲洗等优点,广泛应用于水处理领域。研究了中空纤维超滤膜分离的概念、材质、结构、特性和分离去除机理,综述了中空纤维超滤膜及其组合工艺在水处理中的应用,并展望了未来的应用前景。

With the advantages of effective area of membrane per unit volume was large, the filled density was high, operation pressure and energy consumption were low, the high-throughput and very good for backwash, hollow fi- ber ultrafihration membrane were highly appreciated in field of water treatment and was widely used. The process con cept, material, structures and characteristics of the membrane were introduced, analysed and summarized process princi- ple of the membraneOn this basis, applications of the membrane and its combined process in water treatment were re- viewed. Also the advantages and disadvantages of the membrane in practice were explained, and some prospects were proposed, in order to provide some academic guidances for the practical application of the membrane and its combined process in water treatment.
