围绕碳源问题进行的脱氮除磷工艺改进_王建芳

围绕碳源问题进行的脱氮除磷工艺改进王建芳(中国矿业大学环境测绘学院,江苏徐州221008)摘　要:反硝化菌和聚磷菌在同一系统中竞争少量可溶性有机物引起的矛盾一直是传统生物脱氮除磷工艺的焦点问题.在污水处理系统中碳源的缺乏会影响整个系统的脱氮除磷效果.分析了碳源缺乏的原因,提出了着重从两个方面解决碳源缺乏问题:一方面是在时间或空间上将脱氮除磷分开的工艺改进,另一方面是寻找快速可替代有机碳源,并对有代表性的Biowin工艺的运行情况作了分析.关键词:生物脱氮除磷;碳源;工艺改进中图分类号:X131.2;X703.1文献标识码:A文章编号:1009-8992(2003)02-0042-04TechnologicalImprovementinBiologicalNutrientRemovaltoIncreaseCarbonContentWANGJian-fang(CollegeofEnvironmentandSpatialInformatics,ChinaUniversityofMiningandTechnology,Xuzhou,Jiangsu221008,China)Abstract:Itisafocalprobleminconventionalbiologicalnutrientremovalthatdenitrifyingbacteriacompetewithphosphateaccumulatingorganisms(PAO)forlimiteddissolvedorganisms.Inasewagetreatmentsystem,theshortageoftheelementofcarbonmaylessentheeffectofbiologicalnutrientre-moval.Uponthebasisofananalysisofthefactorscausingtheinsufficiencyofcarboncontent,twomodesoftechnologicalimprovementarerecommendedtosettletheproblemofcarbonsources:oneistoseparatelyarrangetheprocessesofbiologicalnutrientremoval,theother,representedby
