摘　　要：丙烯酰胺功能单体生产废水普遍具有COD、氨氮浓度高,可生化性差等特点。本研究利用铁碳微电解-Fenton-生物联合处理的方法对某丙烯酰胺生产企业综合废水进行处理,运行结果表明,该联合工艺对该类废水具有较强的处理能力与稳定性。Fe/C-Fenton联合预处理可使综合废水B/C从0.17提升至0.33,综合出水COD<120 mg/L,氨氮<30mg/L,满足《污水综合排放标准》(GB8978-1996)二级标准的要求,该组合处理系统综合运行成本为14.21元/m3,显著优于相似废水处理工程。The wastewater from acrylamide production process generally has the characteristics of high COD,ammonia nitrogen concentration and poor biodegradability.In this study,the comprehensive wastewater of an acrylamide production enterprise was treated by using iron-carbon microelectrolysis-Fenton-biological combined treatment method,which shown strong capacity and stability for the wastewater treatment.The Fe/C-Fenton combined pretreatment can increase the B/C ratio of comprehensive wastewater from 0.17 to 0.33,and the comprehensive effluent COD<120 mg/L and ammonia nitrogen<30 mg/L can meet the requirements of the Comprehensive Sewage Discharge Standard(GB8978-1996).The comprehensive operation cost of the combined treatment system is 14.21 yuan/m3,which is significantly better than similar wastewater treatment projects.
