重庆大学本科学生毕业设计重庆市某生态住宅区废水资源化利用工程设计(任务四)学生:黎经纬学号:20076729指导教师:肖海文专业:环境工程重庆大学城市建设与环境工程学院二O一一年六月Graduation Design (Thesis) of Chongqing Universityproject design of waste water utilization for an ecological residential community inChongqingUndergraduate: Li JingweiSupervisor:Associate Prof. Xiao HaiwenMajor: Environmental EngineeringCollege of Urban Construction and EnvironmentalEngineeringChongqing UniversityJune 2011摘要本次毕业设计内容为重庆市某生态住宅区废水资源化利用工程设计,要求根据所提供的基础设计资料和图纸,完成生态住宅区废水资源化利用工程的水量平衡计算和回用水水源(污水、灰水、雨水)选择、方案比较。
再对所选择的方案进行详细的设计计算及回用水管网布置。
进行生态住宅区废水减排率和节水率的计算,并进行环境经济效益分析。
经过水量平衡计算和方案比选,本设计选用二期雨水供二期室外杂用和洗车,收集三期1~7栋灰水供应三期室外杂用和高层冲厕用水。
三期处理规模为300t/d,二期处理规模为212t/d。
三期灰水的处理采用BAF为主体工艺,前设格栅调节池的预处理,BAF池出水进中水池,最后采用管式紫外消毒器进行消毒处理,整个系统流程简洁,处理效率高,出水水质稳定,操作管理方便。
二期雨水处理采用人工湿地技术,调蓄沉淀塘储存前期雨量,并流入后续人工湿地进行处理。
二者均与景观设计相结合,处理雨水的同时美化小区环境,给小区增加了一条风景线。
中水处理站的内部布置紧凑有序,雨水系统结合景观设计,清洁美观。
本次毕业设计的成果包括毕业设计计算说明书及相应的图纸。

And then Calculate for the seleceted scheme in detail and layout reuse water distribution network. Calculate for waste reduction rate and water saving rate of the ecological residential community, and analysis the environmental and economic effectiveness.according to the project comparison,The design chose the second period rain water for its outdoor miscellaneous, and the third period 1 ~ 4 building's gray water for its outdoor use. For the third period gray water processing scale for 300t/d, the second period rain water phase processing scale for 212t/d.For the third period gray water treatment, using BAF enginering for process, adjust the grille pretreatment and pool water into the pond in BAF pool, finally using tubular uv sterilizer disinfected, The whole process is very simple and neat, but the effect is very good. Furthermore, the quality of the reclaimed water is very stable and it is very convenient to operate.treatment of the second period rain water, we use constructed wetlands technology, storage pool storage of pre-precipitation of rainfall and flow into the constructed wetland for further treatment. They both combine with the landscape design, and increase the residential landscape while dealing with rain cell environment.The internal arrangement of the grey Water Treatment Station is compact and order, rainwater treatment system combines landscape design is clean and beautiful. The achievement of this design includes design and calculation paper and the corresponding drawings.Keywords: BAF pool, wetlands, water reuse, living area目录摘要 (I)ABSTRACT........................................................................................................................
