砾间接触氧化+河道人工湿地工艺在中小河流治理中的应用摘要根据农村地区中小河流的水质状况，结合当地地形、土壤、气候、植物等因素，充分利用生物生态方法，采用砾间接触氧化+河道人工湿地工艺直接对污染河流水质进行净化，处理工艺适应性强，建设周期短，投资和运行费用低，维护管理简便，还美化了环境。砾间接触氧化工艺对生化需氧量、化学需氧量、氨氮的去除率均达到60%～70%，出水再经河道人工湿地处理，对总氮、总磷的去除率均达到70%～80%，水质达到Ⅳ类水标准。关键词砾间接触氧化;河道人工湿地;河流治理;应用X52A0517-6611（2020）15-0075-03doi：10.3969/j.issn.0517-6611.2020.15.022开放科学（资源服务）标识码（OSID）：ApplicationofGravelContactOxidation+RiverConstructedWetlandProcessinSmallandMediumsizedRiverManagementXUTianyong（ChuzhouBureauofEcologicalEnvironment，Chuzhou，Anhui239000）AbstractAccordingtothewaterqualityofsmallandmediumsizedriversinruralareas，combinedwithlocaltopography，soil，climate，plantsandotherfactors，thebioecologicalmethodisfullyused，andtheprocessofgravelcontactoxidation+riverconstructedwetlandisadoptedtodirectlypurifythewaterqualityofpollutedrivers.Thetreatmentprocesshasstrongadaptability，shortconstructionperiod，lowinvestmentcost，lowoperationcost，simplemaintenanceandmanagement，andbeautifiestheenvironment.Theremovalrateofbiochemicaloxygendemand，chemicaloxygendemandandammonianitrogenbygravelcontactoxidationprocessis60%-70%.Theremovalrateoftotalnitrogenandtotalphosphorusis70%-80%aftertheeffluentistreatedbyriverconstructedwetland，andthewaterqualityisstabletoclassIVwaterstandard.KeywordsGravelcontactoxidation;Riverconstructedwetland;Rivermanagement;Application作者简介徐天勇（1966—），男，安徽滁州人，高级工程师，硕士，从事污染防治技术研究和管理工作。-全文完-
