Abstract:

The coagulation -UASB -biological contact oxidation process has been used for treating the highlyconcentrated organic wastewater from membrane making. The applied results show that when the COD、BOD₅ and SSof influent are 15 000，7 000，400 mg/L respectively，the removal rates of the three are all above 80%. The effluentwater quality is stable and meet the third class of Integrated Wastewater Discharge Standard（GB 8978-1996）. The effluent water finally discharges into the wastewater treatment plant in Nantong Development Zone.

Key words: wastewater from membrane making, up-flow anaerobic sludge bed, biological contact oxidation

摘要：

采用混凝-UASB-生物接触氧化工艺对制滤膜过程中产生的高浓度有机废水进行处理。工程运行结果表明,在进水COD、BOD₅、SS分别为15 000、7 000、400 mg/L的条件下,三者的去除率均在80%以上,出水水质达到GB 8978-1996《污水综合排放标准》的三级标准要求,尾水最终排入南通开发区污水处理厂。
