A_O_BAF工艺处理高氨氮煤化工废水_俞彬A/O+BAF工艺处理高氨氮煤化工废水俞彬,陈广升,王玉慧,迟娟(博天环境集团股份有限公司,北京100081)摘要:采用A/O+BAF工艺处理包头煤化工项目的生产废水。运行结果表明:当综合进水COD和NH3-N浓度分别为800~1800mg/L和150~250mg/L时,对COD和NH3-N的去除率分别在92%和95%以上,出水水质稳定达到《污水再生利用工程设计规范》(GB50335—2002)规定的再生水用作冷却水的水质标准(pH值为6.5~9,COD≤60mg/L,BOD5≤10mg/L,NH3-N≤10mg/L)。该工艺系统运行稳定,耐冲击负荷能力强,处理成本低,为煤化工废水处理提供了解决思路。关键词:煤化工废水;高氨氮;A/O工艺;BAF工艺中图分类号:X703.1文献标识码:C文章编号:1000-4602(2013)06-0081-04A/O+BAFProcessforTreatmentofCoalChemicalWastewaterwithHighAmmoniaNitrogenYUBin,CHENGuang-sheng,WANGYu-hui,CHIJuan(PotenEnvironmentGroupCo.Ltd.,Beijing100081,China)Abstract:A/O+BAFprocesswasusedtotreatcoalchemicalwastewater.TheoperationresultsshowedthatwhentheinfluentconcentrationsofCODandNH3-Nwereintherangeof800to1800mg/Land150to250mg/L,respectively,theremovalratesofCODandNH3-Nwerehigherthan92%and95%,respectively.TheeffluentqualitycouldmeetthereclaimedwatercriteriausedascoolingwaterinCodeforDesignofWastewaterReclamationandReuse(GB50335-2002),suchaspH6.5to9,COD≤60mg/L,BOD5≤10mg/LandNH3-N≤10mg/L
