摘　　要：以某钛白粉厂产生的高氯化工排水为原水,采用中试A/O工艺装置模拟废水接受处理厂的处理工艺,通过逐步提高进水氯离子和水力负荷的驯化方法验证处理效果及技术可行性。结果表明,在系统缺氧停留时间9.6 h、好氧停留时间为13.8 h、氯离子浓度为4 000~4 800 mg/L时,出水COD为17.6~46.2 mg/L、NH3-N为1.5~4.4 mg/L、TN小于13 mg/L,稳定达到镇污水处理厂污染物排放标准(GB 18918-2002)中一级A排放标准,通过生物相分析,驯化后污泥性状良好,但驯化过程中,水力负荷应逐步少量提高,避免系统硝化功能崩溃。经核算,吨水运行成本为0.87元。The effect and technical feasibility of A/O process for treatment of the high chlorination effluent form titanium dioxide production was investigated in a pilot-scale test.The results showed that the COD,NH3-N、TN of the effluent were 17.6~46.2 mg/L、1.5~4.4 mg/L and less than 13 mg/L,the effluent quality meet the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB18918-2002).Through biofacies analysis,the acclimated sludge has a good character.But In the process of acclimation,the hydraulic load should be gradually increased a little to avoid the breakdown of the nitrification function.The operation cost of the reactor was 0.87 yuan/m3.
