Abstract:

China University of Tethnology,Guangzhou510640,China) Based on experimentsin lab,pilot-plant study of the bleaching and dyeing wastewater treatment hasbeen carried on.The result showsthat after the technology which includesthe pivotal facility of highly efficient in-tegral wastewater treating equipment isused,in combination with the two-stage sand filtration,to treat thiskind of wastewater,the COD Cr of the treated wastewater isonly92～138mg/L,itspH value is6.3,and the suspended solid is20mg/L.All of the treated water can be reused.It doesn't have any ill effect,but makesgood economic profits.

Key words: bleaching and dyeing wastewater, highly efficient integral wastewater treating equipment, reuse

摘要：

在实验室小试的基础上对漂染废水进行了中试试验研究，结果表明:采用漂洗废水特效一体化废水处理设备为核心，同时结合二级过滤处理的工艺流程对漂洗后废水进行处理，经处理后废水COD_Cr仅为92～138mg/L，pH为6.3，SS为20mg/L，将处理后废水全部回用于生产，对漂洗结果无影响且具有良好的经济效益。
