摘要：

采用混凝—优势菌活性污泥工艺进行了处理含PVA退浆废水的小试研究，其中活性污泥中接种了PVA降解优势菌。处理后COD_Cr去除率达到93.52%，出水水质达到了GB4287—1992《纺织染整工业水污染物排放标准》中的二级排放标准。

Abstract:

The treatment of the PVA desizing wastewater by coagulation-dominant bacteria active sludge process has been studied in small scale test. PVA degradation dominant bacteria have been inoculated into the active sludge. As a result, the removal rate of COD_Cr is 93.52% and the treatment effect can reach the secondary standards of GB 4287—1992.

Key words: polyvinyl alcohol, desizing wastewater, coagulation sedimentation, degradation bacteria
