sbbr脱氮与人工湿地除磷联合工艺应用解析.doc

强化SBBR脱氮与人工湿地除磷联合工艺的研究摘要：本文在总结国内外脱氮除磷工艺的基础上，提出了强化SBBR脱氮与人工湿地除磷联合工艺并建立、启动了该工艺的试验装置。SBBR采用新型两格交替运行形式，强化了碳源保存和同步硝化反硝化脱碳效率；人工湿地选种的植物为菖蒲和矮生百慕大草，以进一步去除SBBR出水中的磷。通过测试分析，该工艺具有稳定的脱氮除磷能力，氮、磷的去除率分别能达到92%、91%，是一种新型的有效污水处理工艺。关键词污水处理脱氮除磷SBBR人工湿地AcombinedprocesswithenhancedSBBRfornitrogenremovalandconstructedwetlandsforphosphorusremovalABSTRACTThispapergivesareviewondevelopmentofnitrogenandphosphorusremovalprocessesintheworldandproposesacombinedprocesswithenhancedSBBRfornitrogenremovalandconstructedwetlandsforphosphorusremoval.ThisSBBRoperatedalternatelyintwosimilarpartsofthereactortoimprovesimultaneousnitrificationanddenitreification(SND).CalamusandBermudagrasswereplantedintwoconstructedwetlandsforfurtherphosphorusremoval.Accordingtotheexperimentaltestingandanalyzing,itdemonstratesthattheprocesshasagoodandstablenitrogenandphosphorusremovalcapability.Thenitrogenandphosphorusremovalratesreach92%,91%,respectively.Thisisanewtypeofeffectivewastewatertreatmentprocess.KeywordswastewatertreatmentnitrogenandphosphorusremovalSBBRconstructedwetland目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc231733631"1绪论PAGEREF_Toc231733631\h1HYPERLINK\l"_Toc231733632"1.1氮、磷污染的来源及其危害PAGEREF_Toc231733632\h1HYPERLINK\l"_Toc231733633"1.1.1氮、磷污染的来源及其影响因素PAGEREF_Toc231733633\h1HYPERLINK\l"_Toc231733634"1.1.2氮、磷污染的危害PAGEREF_Toc231733634\h1HYPERLINK\l"_Toc231733635"1.2生物脱氮除磷的基本原理PAGEREF_Toc231733635\h2HYPERLINK\l"_Toc231733636"1.2.1生物脱氮原理PAGEREF_Toc231733636\h2HYPERLINK\l"_Toc231733637"1.2.2生物除磷原理PAGEREF_Toc231733637\h4HYPERLINK\l"_Toc231733638"1.3生物脱氮除磷工艺PAGEREF_Toc231733638\h5HYPERLINK\l"_Toc231733639"1.3.1活性污泥法脱氮除磷工艺PAGEREF_Toc231733639\h5HYPERLINK\l"_Toc231733640"1.3.2生物膜法脱氮除磷工艺PAGEREF_Toc231733640\h6HYPERLINK\l"_Toc231733641"1.3.3人工湿地脱氮除磷工艺PAGEREF_Toc231733641\h7HYPERLINK\l"_Toc231733642"1.4传统生物脱氮除磷工艺存在的问题及解决思路PAGEREF_Toc231733642\h7HYPERLINK\l"_Toc231733643"1.5本论文研究内容PAGEREF_Toc231733643\h8HYPERLINK\l"_Toc231733644"2强化SBBR脱氮与人工湿地除磷联合工艺处理
