污泥自热高温好氧消化工艺及影响因素污泥自热高温好氧消化工艺及影响因素�张艳萍,彭永臻,牛奕娜,姜安玺(北京工业大学北京市水质科学与水环境恢复重点实验室,北京100022)��摘要:介绍了污泥自热高温好氧消化(ATAD)技术,其具有污泥稳定与杀菌的双重功效,处理效率高,体积小、运行方便。经过消化处理后的污泥,大部分病原菌被灭活,可以作为一种富养分、高质量的肥土应用于农田。文中对ATAD的工艺原理、流程、反应器构造及影响因素等进行了探讨。关键词:污泥处理;自热高温好氧消化;工艺参数;病原菌灭活中图分类号:X703��文献标识码:A��文章编号:(K)04259(原1002-1264)(2005)03-0031-03ProcessandAffectingFactorsofAutothermalThermophilicAerobicDigestionforOrganicSludgeTreatmentZHANGYan�ping,PENGYong�zhen,NIUYi�na,JIANGAn�xi(KeyLaboratoryofBeijingforWaterQualityScienceandWaterEnvironmentRecoveryEngineering,BeijingUniversityofTechnology,Beijing100022,China)Abstract:Withthedevelopmentofwastewatertreatment,theprocessinganddisposalofthesludgewhichproducedfromwastewatertreatmentplantarearisingmoreandmoreattention.Asludgedigestiontechnology-ATAD(au�tothermalthermophilicaerobicdigestion)isintroducedinthepaper.ATADdecomposetheorganicmattertostabilizesludge,andaccomplishahighdegreeofpathogenreduction.Thedigestedsludgeisturnedintoastableandhygien�icproduct.Thehygienicqualityo
