双污泥系统反硝化除磷工艺研究进展_厉巍

双污泥系统反硝化除磷工艺研究进展厉巍，李燕，张传义(中国矿业大学环境与测绘学院，江苏徐州221008)摘要：反硝化除磷菌采用“一碳两用”的方式实现了反硝化脱氮并化解了反硝化菌和聚磷菌之间碳源竞争的矛盾。基于该技术的双污泥系统，对于解决目前脱氮和除磷这一难点、热点问题，提供了一种新的思路。目前较典型的双污泥系统是A2NSBR工艺、A2N工艺以及一些改良工艺。在此基础上，结合“分点进水”理论，提出了新的一种改良的双污泥系统。关键词：反硝化除磷；一碳两用；双污泥系统；分点进水；改良工艺中图分类号:X703文献标识码：A文章编号：1004-874X（2010）12-0153-02Theprogressoftwo-sludgesystemdenitrificationremovaltechnologyLIWei,LIYan,ZHANGChuan-yi（SchoolofEnvironmentScienceandSpatialInformatics,ChinaUniversityofMiningandTechnology,Xuzhou221116,China）Abstract:Denitrifyingphosphorusremovingbacteriausingone-carbondual-usemeanstoachievedenitrificationdenitrifyingbacteriaandcarbonsourcecompetitionbetweenPAOscontradictionatthesametime.Thetechnologybasedontwo-sludgesystemisaconceptofnewtechnologycompletelydifferentfromthenitrogenandphosphorusremovalingeneral,andit’sanewwaytosolvethedifficultandpopularquestionsofthenitrogenandphosphorusremoval.Atpresent,moretypicaltwo-sludgesystemsaretheA2NSBRprocessandtheA2Nprocess,andsomeoftheimprovementprocessbasedonit.Onthisbasis
