摘　　要：采用"混凝沉淀-水解-UASB-泥膜复合A/O"工艺处理含高浓度有机物、氨氮和硫酸根的味精污水。结果表明:该工艺对BOD5、COD、SS、氨氮和TN的去除率分别为99.9%、99.6%、99.0%、97.5%和97.3%,出水水质优于GB 8978—1996《污水综合排放标准》中表4的一级排放标准。该工艺耐冲击负荷能力强、投资省、运行费用低,能创造显著的环境、经济和社会效益。The coagulation sedimentation ＋ hydrolysis ＋ UASB ＋ sludge-biofilm A/O process was designed for treating the monosodium glutamate wastewater. The removal efficiencies of BOD5 , COD, SS, NH3-N, and TN in the process were over 99.9% , 99.6% , 99.0% , 97.5% and 97.3% , respectively, which were superior to the first level standard stipulated in ＂Integrated Wastewater Discharge Standard （Table 4 in GB 8978-1996）. Results indicated that the process had a strong impact resistant capacity, low investment and operating costs, which could create significant environmental, economic and social benefits.
