一种低污泥产量_低能耗印染废水处理工艺_王学华_黄勇_张娜

书书书一种低污泥产量、低能耗印染废水处理工艺王学华，黄勇，张娜(苏州科技学院环境科学与工程学院，江苏苏州215009)摘要:针对现行印染废水处理工艺污泥产量大和能耗高等问题，设计了以UASB反应器+三段好氧池为主体的印染废水处理工艺。运行结果表明，平均污泥产量及能耗分别为1283g/m3与0．45kW·h/m3，与其他印染废水处理工艺相比，该工艺具有污泥产量低、能耗低等特点，出水水质优于《城镇污水处理厂污染物排放标准》(GB18918—2002)的一级A标准。关键词:印染废水;厌氧上流式反应器;低污泥产量;低能耗中图分类号:X703．1文献标识码:C文章编号:1000－4602(2014)04－0063－05StudyonaPrintingandDyeingWastewaterTreatmentProcesswithLowSludgeYieldandLowEnergyConsumptionWANGXue-hua，HUANGYong，ZHANGNa(SchoolofEnvironmentalScienceandEngineering，SuzhouUniversityofScienceandTechnology，Suzhou215009，China)Abstract:AprintinganddyeingwastewaterprocesscomposedofUASBandthree-stageaerobictankwasdesignedtoresolvetheproblemsofhighsludgeyieldandhighenergyconsumptionintheexist-ingwastewatertreatmentprocess．Theoperationresultsshowedthattheaveragesludgeyieldandenergyconsumptionwere1283g/m3and0．45kW·h/m3．Thiscombinedprocesshadanadvantageoverotherprintinganddyeingwastewatertreatmentprocessesinsludgeyieldandenergyconsumption．TheeffluentqualityexceededthefirstlevelAcriteriaspecif
