摘　　要：将高级氧化技术、生活污水稀释与厌氧、好氧技术组合工艺应用于低pH、高含盐的含邻硝基对甲酚废水处理站改造工程,运行结果表明,当H_2O_2添加量为5 kg/t,FeSO_4·7H_2O的添加量为6.8 kg/t时可对含邻硝基对甲酚废水中的苯环有效断链,提高废水的可生化性。预处理后的废水在UASB停留时间1.4 d,缺氧、好氧停留时间均为1 d时,出水COD<500 mg/L,达到《污水排入城镇下水道水质标准》(CJ 343—2010)中A等级的标准。Advanced oxidation technology,domestic sewage dilution,and aerobic technique combined technologyhave been applied to the modification project of a wastewater treatment plant for 2-nitro-paracresol production. Inthe wastewater,its p H is low and salinity is high. The operation results show that benzene ring in the wastewatercontaining 2-nitro-paracresol could effectively be broken and improve the biodegradability of the wastewater,whenthe addition of H2O2 is 5 kg/t and Fe SO4·7H2O 6.8 kg/t. When HRT of UASB is 1.4 d,anoxia 1 d,and aerobic 1 d,the effluent COD of the pretreated wastewater is below 500 mg/L,reaching Level A standard specified in theWastewater Quality Standards for Discharge to Municipal Sewers（CJ 343—2010）.
