铁炭内电解-厌氧-好氧工艺处理阿维菌素废水的试验研究李再兴　杨景亮　罗人明　罗　晓　邓晓丽(河北科技大学,石家庄050018)摘　要　血清瓶毒性试验表明,AVM对厌氧消化产生强烈的抑制作用。AVM废水经铁炭内电解预处理后,COD和AVM的去除率分别达到19.5%和68.5%,可大大降低废水的毒性。预处理出水再经UASB+生物接触氧化反应器进一步处理,当生化系统进水COD为6000—6500mg/L时,出水COD为250—280mg/L,总COD去除率达到95.6%,出水达到生物制药行业排放标准。关键词　AVM废水　毒性试验　铁炭内电解　UASB反应器　生物接触氧化反应器Studyonavermectinwastewatertreatmentbyironinternalelectrolysis-anaerobic-aerobicproccessLiZaixing　YangJingliang　LuoRenming　LuoXiao　DenXiaoli(HebeiTechnologyandScienceUniversity,Shijiazhuang050018)Abstract　ThetoxicityexperimentinserumbottleshowsthatAVMhasseriousinhibitingeffectonanaerobicdigestion.Theironinternalelectrolysistechnologycanreducethisinhibitingeffect,theCODandAVMremovalratereached19.5%and68.5%respectively.ThenthewastewaterwastreatedbyUASBreac-torctorandbiologicalcontactoxidationreactor,whenthesysteminfluentCODwas6000—6500mg/L,theef-fluentCODwas250—280mg/L,totalCODremovalratereached95.6%,theeffluentcanmeetthewastewa-terdischargestandardofbiologicalpharmacy.Keywords　avermectinwastewater;toxic
