摘　　要：针对某有机溶剂回收精制车间生产废水特点,高浓废水采用铁碳-芬顿氧化工艺预处理后,与厂区内低浓废水进行混合再采用UASB-AO/深度处理工艺进行处理。工程实践表明,综合废水COD_(Cr)从15000 mg/L降低到出水<500 mg/L,去除率>97%,出水水质满足园区污水处理厂接管标准。The high-concentration wastewater was pretreated by Fe-C micro-electrolysis and Fenton Oxidation-process according to the characteristics of the recovered and refined organic solvent wastewater discharged.Then mixed with low-concentration wastewater,treated by UASB-AO/Advanced process.The engineering practice showed,COD_(Cr) in wastewater reduced from 15000 mg/L to<500 mg/L,the removal rate is greater than 97%,that the effluent quality met the takeover standard by park sewage plant.
