Abstract:

Ten different ways to cleaning polysulfone hollow fiber ultrafiltration membr ane fouled by wastewater in sericin plants are studied. The result show that the alkaline solut ion( M solution)which consists o f 0.1% NaOH, 0.5% NaClO, 0.1% penetrant etc. has the best effect on the membrane fouled by sericin protein.

摘要：

采用十种不同的膜清洗方法对超滤丝厂废水后被污染的中性聚砜中空纤维超滤膜进行了研究。结果表明：0.1%NaOH、0.5%NaClO、0.1%渗透剂等组成的碱性溶液(简称M溶液)对丝胶蛋白造成的膜污染具有最佳清洗效果
