摘要：

采用中性聚砜中空纤维管式超滤装置，对丝厂废水中的煮茧水在不同pH值条件下的超滤进行了研究，结果表明，该超滤膜对丝厂废水超滤的最佳条件是碱性范围。浓缩60倍的浓缩液，其蛋白质含量高达7.75%(质量分数)。

Abstract:

Neutral polysulf one hollow fiberul trafiltration used to treat the cocoon-boiling wastewater in silkreeling factories has been studies.The result shows that the optimumcon dition of the ultrafiltration membraneis alkaline.When the liquid is concentrated by 60 times，its cericin content is a shigh as 7.75%.

Key words: ultra filtration, cocoon-boiling wastewater, volume of filtration, waterflux
