[Objective] The research aimed to study treatment effect of the pesticide wastewater by the composite process of biological active carbon filter-fluid bed. [ Method ] The composite process of biological active carbon filter-fluid bed was applied to treat the mixed pesticide wastewater. The removal efficiencies of CODCr, BOD5, NH3 -N, SS and the influence factors were investigated. [ Result ] The composite process had good treatment efficiency for the pesticide wastewater. After running stably, the average removal rates of CODCr , BOD5 , NH3-N and SS were respectively 91. 6% 、96. 2% 、90. 2% and 87. 5%. All the indices reached the third level criteria specified in Integrated Wastewater Discharge Standard (DB12/356-2008). [Conclusion] The whole system operates reliably and simply, and provides a stable, convenient and economical solution for deep treatment of the mixed pesticide wastewater.%[目的]研究多级生物活性炭滤池-流化床复合工艺对农药废水的处理效果.[方法]应用多级生物活性炭滤池-流化床复合工艺处理某农药企业综合废水,考察了其对CODCr、BOD5 、NH3-N和SS的去除效果及影响因素.[结果]该复合工艺对农药废水具有良好的处理效果,稳定运行后,CODCr、BOD5、NH3-N和SS的平均去除率能达到91.6％、96.2％ 、90.2％和87.5％,出水水质可以稳定达到天津市《污水排放综合标准》(DB12/356-2008)中三级的要求.[结论]该试验系统结构简单,运行可靠,为农药生产企业综合废水的深度达标处理提供了一种稳定、简便和经济的解决方案.
