题 目 某住宅小区中水回用处理工艺设计 学生姓名 余 成 学号 1111044037 所在学院 化学与环境科学学院 专业班级 环境工程1102班 指导教师 刘 瑾 完成地点 环境工程实验室 2015 年 6月 3 日 某住宅小区中水回用处理工艺设计 余成 （陕西理工学院化学与环境科学学院环境工程1102班，陕西 汉中 723000） 指导老师：刘瑾 [摘要]：本设计以某住宅小区污水为处理工程设计对象设计处理能力为300m3/d设计进水水质为：BOD=150mg/LCOD=300mg/L，SS=280mg/L。本设计的流程为：进水格栅调节池平流沉砂池膜生物反应池清水池紫外线消毒回用。回用水质符合《城市污水再生利用 城市杂用水水质》（GB/T18920-2002）标准。本设计的中水主要回用于城市绿化、车辆冲洗、冲厕本设计采用MBR工艺，该工艺技术先进、出水水质好、运行稳定、占地面积小、易于管理维护。 [关键词]： The Engineering Design Of Reuse Project Of Intermediate Water In a Residential District YU Cheng (Grade11, Class2, Major Environmental Engineering, School of Chemical and Environmental Science, Shaanxi University of Technology, Hanzhong 723000, Shaanxi) Tutor: Liu Jin Abstract :In this design, the wastewater was become the treatment target from the residential district.The capacity of designed treatment is 300 m3/d. The concentrations of BOD5,COD, and SS are 150mg/L ,300mg/L and 280mg/L for influent quality. The design of the process is influent—grid—water regulating tank—horizontal-flow grit chamber—membrane bioreactor pool—clean water tank—ultraviolet disinfection—reuse.The water conform to the reuse of recycling water for urban Water quality standard for urban miscellaneous water consumption?(GB/T18920-2002).In this design,the reuse water is mainly used for city greening, vehicle flushing, toilet flushing .This design uses MBR technology.The process has such features as technology advanced ,good water quality, steady operation, small floor area, easy to management.
