摘　　要：介绍了AO-MBR-RO工艺在液晶平板显示(TFT-LCD)工业废水回收利用中的应用情况,包括设计要求、工艺流程、设计参数、调试及运行效果,对运行成本进行了分析。设计系统进水电导率≤400μS/cm、COD≤450 mg/L、NH3-N≤20 mg/L、TP≤2. 0 mg/L,处理水量为10 000 m^3/d。系统产水电导率为26. 2μS/cm、COD为1. 68 mg/L、NH_3-N为0. 3 mg/L、TP未检出,处理成本为1. 91元/m^3。该工艺运行稳定,水质合格,在TFT-LCD以及其他相关行业具有推广价值。The application of AO/MBR/RO process in the advanced treatment and reuse of TFT- LCD industrial wastewater was introduced, including the process design requirements, process flow, design parameters, commissioning, project operation and the running cost analysis. The design conductivity, COD, NH3-N and TP of raw water were no more than 400 μS/cm, 450 rag/L, 20 mg/L and 2.0 mg/L, respectively. The final effluent conductivity, COD and NH3-N were 26.2 μS/cm, 1.68 mg/L and 0.3 mg/L respectively, while effluent TP was not detected. The treatment capacity is 10 000 m^3/d and the cost of advanced treatment was 1.91 yuan/m^3. The AO/MBR/RO process has operated stably and the effluent quality was qualified, which has wide application value in TFT-LCD and other related industrial wastewater treatment.
