摘　　要：根据味精废水和饮料废水水质互补性较强的特点,将味精废水和饮料废水混合,可降低味精废水中有机污染物浓度,并提高饮料废水可生物降解性。选用水解酸化-接触氧化-生物炭三段式生物法工艺对混合废水进行处理,节省了工程投资。2年多的运行结果表明,在混合进水中有机污染物、氨氮等浓度较高的条件下,经上述工艺处理后,出水水质可达到GB 8978—1996的一级排放标准,COD和BOD的去除率均超过99%,氨氮的去除率超过96%。Based on the characteristics of good complementarity between the quality of monosodium glutamate wastewater and beverage wastewater, the mix of the two types of wastewater is consider to decrease the concentration of organic pollutants in monosodium glutamate wastewater and improve the biodegradation of beverage wastewater. A three-phase combination process of hydrolyzation-aerobic-biological carbon treatment was used to treat the mixed wastewater. The two-year rtmning results showed that the water quality of effluent could meet the standard of GB 8978-1996 （Grade 1 ）, even if the water of influent having high concentration of organic pollutants and ammonia nitrogen, the degradation rates of COD and BOD were over 99% simultaneiously,and that of ammonia was over 96% .
