摘要：

采用浸没式膜生物反应器(MBR)处理化工废水，处理能力60m³/h，进水COD_Cr、NH_3-N、SS质量浓度分别为533、182、86mg/L，处理后，出水COD_Cr、NH_3-N、SS分别为8、28.5、6mg/L，去除率分别达到94.6%、95.6%、93%,且出水清澈稳定，可回用至循环冷却水系统。

Abstract:

The experience of MBR process used for treating highly concentrated chemical wastewater is introduced.The treating capacity of the plant is 60 m³/h, the influent water COD_Cr is 533 mg/L, NH_3-N is 182 mg/L, and SS is 86 mg/L.After the treatment, the effluent water COD_Cr is 8 mg/L, NH_3- is 28.5 mg/L, and SS is 6 mg/L.Their removal rates are 94.6%, 95.6% and 93% respectively.The outlet water is clear and steady and can be recycled to circulating cooling water systems.

Key words: membrane bioreactor, chemical wastewater, wastewater reuse
