摘　　要：针对某存量农药化工废水水质复杂,氨氮浓度高,可生化性差的特点,采用“前芬顿氧化+氨氮吹脱+水解酸化+两级A/O+后芬顿氧化”的工艺进行处理。该工艺适应复杂的水质,而且处理效果稳定。实际运行数据表明,COD、氨氮、TP去除率分别达到92%和98%及96%以上,出水COD≤100 mg/L、ρ(NH_(3)-N)≤15 mg/L、ρ(TP)≤1mg/L,稳定达标排放。经成本核算,该处理项目运行成本为62.96元/t。该方法可为实际农药化工废水的有效处理提供参考。Owing to the high ammonia nitrogen concentration(NH_3-N),poor biodegradabilityand toxicity,the combination of "Pre-fenton oxidation+ammonia nitrogen stripping+hydrolytic acidification+two-stage A/O+post Fenton" process is selected for treatment.The process issuitable for complex water quality treatment.The actual operation data showed that the removal rate of COD、 ammonia nitrogen and TP reached 92%、 98%and 96%above respectively,and the effluent COD≤100 mg/L,NH_3-N≤15 mg/L,TP≤1 mg/L,which stably met the first-level discharge standard of the GB 8978-1996.In addition,the total operation cost of the project was 62.96 RMB/ton.The method can provide reference for effective treatment of pesticide wastewater.
