制药废水处理方案的确定及试验效果分析_孙洪涛

制药废水处理方案的确定及试验效果分析孙洪涛　秦霄鹏　高　磊(山东省环境保护科学研究设计院,山东济南250013)摘要:制药废水具有排放量小、成分复杂、浓度和盐分高、色度和毒性大等特点,属于难降解高浓度有机废水,易造成水环境污染,威胁人们的健康。通过分析山东某制药厂的废水性质,确定治理方案为内电解-UASB-氧化沟工艺,在进水ρ(COD)平均为12500mgL、ρ(BOD5)为3500mgL,其出水分别为360和100mgL,平均去除率分别为97.1%和95.5%,出水水质可达CJ3082—1999《污水排入城市下水道水质标准》。试验结果表明,该工艺处理效果稳定,耐冲击负荷能力高。关键词:内电解;UASB;氧化沟;制药废水DETERMINATIONOFSCHEMEOFTREATINGPHARMACEUTICALWASTEWATERANDANALYSISOFTESTEFFECTSunHongtao　QinXiaopeng　GaoLei(ShandongAcademyofEnvironmentalScience,Jinan250013,China)Abstract:Thepharmaceuticalwastewaterfeatureslessemission,complicatedcomposition,highconcentration,highcolorityandtoxicityetc.Itbelongstoahighconcentrationorganicwastewaterofdifficultdegradation.Itcanpollutetheenvironmentofwaterandthreatensthepeople'shealth.Innerelectrolysis-UASB-oxidationditchprocesswasdecidedonthebasisofpracticalinvestigationonthepropertyofthewastewater.Whentheρ(COD)andρ(BOD5)oftheinfluentwere12500and3500mgLrespectively,thoseoftheeffluentwere360and100mgL,whichwasstableandquitegoodtomeettherequireme
