摘　　要：氯乙酸生产废水具有有机物浓度高、含盐量高、难生物降解等特点。采用EGSB和好氧组合工艺进行处理,调试运行结果表明,生化系统经过调试驯化之后,处理效果稳定,抗冲击负荷能力强,出水COD<500 mg/L,出水水质满足下游园区污水处理厂接管标准。The combined process of expanded granular sludge bed(EGSB)and aerobic tank was applied to treat the wastewater from chloroacetic acid production,which has the characteristics of high organic matter concentration,high salt content and refractory to biodegradation.The results of commissioning operation showed that the process had steady treatment effect and strong resistance to shock loading,and the effluent COD was lower than 500 mg/L after the commissioning and domestication of the biochemical system.The effluent quality could meet the discharged standard of the downstream sewage treatment plant in the industrial park.
