MAP－铁碳芬顿－A2/O组合工艺处理高氨氮制药废水雷颉1，方红莲1，郭勤2，陈春丽3(1．南昌理工学院新能源与环境工程学院，江西南昌330044;2．江西省交通设计研究院有限责任公司，江西南昌330052;3．南昌大学资源环境与化工学院鄱阳湖环境与资源利用教育部重点实验室，江西南昌330047)摘要:江西某制药厂将废水分成高浓度生产废水和生活污水两类，分质收集并进行预处理。高浓度生产废水采用鸟粪石(MAP)化学沉淀－铁碳芬顿组合工艺预处理，之后与生活污水混合进入生化段，生化段采用A2/O+BAF组合工艺。运行结果表明，该组合工艺对高氨氮制药废水降解性能良好，最终出水COD与NH3－N浓度分别为103．5、22．5mg/L，对COD和NH3－N去除率分别达到95．2%和91．6%;出水各项指标均可达到《化学合成类制药工业水污染物排放标准》(GB21904—2008)。该系统运行稳定，耐冲击负荷能力较强，具有处理效果良好、处理成本较低等优势。关键词:高氨氮废水;鸟粪石;高级氧化;生物脱氮中图分类号:TU992文献标识码:B文章编号:1000－4602(2019)18－0088－06基金项目:国家自然科学基金资助项目(51568048)ApplicationofMAP－Fe/C-Fenton－A2/OProcesstoTreatPharmaceuticalWastewaterContainingHighConcentrationofAmmoniaNitrogenLEIJie1，FANGHong-lian1，GUOQin2，CHENChun-li3(1．SchoolofNewEnergyandEnvironmentalEngineering，NanchangInstituteofTechnology，Nanchang330044，China;2．CommunicationsDesign＆ＲesearchInstitureCo．Ltd．ofJiangxiProvince，Nanchang330052，China;3．EducationDepartmentKeyLabofEnvironmentandＲesourcesUtlizationofPoyangLake，SchoolofＲesourcesEnvironmental＆ChemicalEngineering，NanchangUniversity，Nanchang330047，China)Abstract:ThewastewaterofapharmaceuticalcompanyinJiangxiProvincewascollectedseparatelyashighconcentrationproductionwastewateranddomesticwastewater．ThehighconcentrationorganicwastewaterwaspretreatedwithMAP－Fe/C-Fentonoxidationprocessandthenmixedwithdomesticwastewaterintothebiologicaltreatmentsection．ThecombinedprocessofA2/O－BAFwasadoptedinthebiologicaltreatmentsection．Theoperationresultsshowedthattheprocesshadgoodtreatmenteffectforhigh-ammonianitrogenpharmaceuticalwastewater．ThefinaleffluentconcentrationsofCODandNH3－Nwere103．5mg/Land22．5mg/L，withtheremovalratesof95．2%and91．6%respectively．AlltheeffluentindicatorscouldmeettherequirementsspecifiedintheDischargeStandardsofWaterPollutantsforPharmaceuticalIndustryChemicalSynthesisProductsCategory(GB21904－2008)．Thesystemhadtheadvantagessuchasstableoperationandtreatment，strongimpactload·88·第35卷第18期2019年9月中国给水排水CHINAWATEＲ＆WASTEWATEＲVol．35No．18Sep．2019resistance，goodtreatmenteffectandlowtreatmentcost．Keywords:highc
