摘要随着人类活动和城市影响力的迅速发展,水循环被破坏,城市屋顶绿化,道路材质本来就是不透水表面，由于大雨所产生的问题也逐渐显露出来,主要在洪涝灾害、雨水径流污染和生态环境的破坏。雨水属于非传统水源，在一定条件下可以减轻水资源匮乏的压力。本说明书是对市政雨水生物滞留处理装置进行了系统设计，并对江苏大学新校区图书馆的屋面雨水进行具体的方案设计说明。本设计说明书主要围绕以下几点进行展开：（1）对市政雨水生物滞留处理装置的重要意义进行了分析，对面国内外研究发展现状与建设情况进行介绍。（2）对江苏大学图书馆汇水面积进行了划分，并屋面、路面的排水系统进行介绍，同时对屋面雨水生物滞留处理装置进行设计计算和图纸说明。（3）对现阶段的雨水生物滞留装置进行了介绍，并对江苏大学新校区图书馆的屋面雨水的生物滞留处理装置进行具体的设计及说明。（4）对市政雨水生物滞留处理装置进行经济、环境效益等分析。经过方案分析和比较，本设计采取的市政雨水生物滞留处理装置主要是由雨水花园、弃流装置组合而成的，无论从经济的角度上，还是从环境效益及社会效益上看，都具有很好的效果，同时具有很强的适用性和重要的推广意义。在水资源紧缺的情况下，合理利用雨水资源是本设计最重要的设计理念。关键词：市政雨水、生物滞留处理装置、雨水花园ABSTRACTWiththerapiddevelopmentofhumanactivitiesandtherapiddevelopmentofurbanization,theoriginalhydrologicalcyclehasbeendestroyed,theurbangreenspacebytheroof,roadsandotherimpervioussurfacereplaced,theraincausedtheproblemhasbeengraduallyhighlighted,mainlyintherunoffpollution,Floods,rainwaterlossandecologicaldamage.Rainasanon-traditionalwatersource,toacertainextent,easethepressureofwaterresources.Thismanualisasystematicdesignofthemunicipalrainwaterbiologicaltreatmentdevice,andtheJiangsuUniversityofthenewcampuslibraryroofrainwaterspecificprogramdesigndescription.Thedesignbrochurefocusesonthefollowingpoints:(1)Theimportanceofmunicipalrainwaterbiologicalretentiontreatmentdeviceisanalyzed,andthepresentsituationandconstructionsituationofresearchanddevelopmentathomeandabroadareintroduced.(2)TheriverareaofJiangsuUniversitylibraryisdivided,andthedrainagesystemofroofandpavementisintroduced.Atthesametime,thedesignandcalculationoftheroofrainwaterbiologicaltreatmentdevicearedescribed.(3)Thispaperintroducestherainwaterbiologicalretentiondeviceatpresentstage,anddesignsandexplainsthebiologicalretentivetreatmentdeviceoftheroofrainwaterofthenewcampuslibraryofJiangsuUniversity.(4)Analyzetheeconomicandenvironmentalbenefitsofthemunicipalrainwaterbiologicaldetentiondevice.Aftertheprogramanalysisandcomparison,thedesignofthemunicipalrainwaterbiologicalretentiontreatmentdeviceismainlycomposedofrainwatergarden,abandonedflowdevicecombination,bothfromtheeconomicpointofview,orfromtheenvironmentalandsocialbenefitspointofview,haveaveryGoodeffect,butalsohasastrongapplicabilityandimportantsignificanceofthepromotion.Inthecaseofwatershortage,therationaluseofrainwaterresourcesisthedesignofthemostimportantdesignconcept.KEYWORDS:Municipalrainwater、biologicalretentiontreatmentdevice、rainwatergarden目录第一章绪论...............................................................11.1引言................................................................11.2生物滞留装置概述....................................................11.2.1概念与构造...................................................11.2.2生物滞留装置应满足的要求.....................................11.3国内外研究现状及进展................................................21.3.1国外研究现状.............
