题 目 某住宅小区中水回用处理工艺设计 所在学院化学与环境科学学院专业班级环境工程指导老师完成地点环境工程实验室 某住宅小区中水回用处理工艺设计[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/L，COD=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/T18920-2024）标准。本设计的中水主要回用于城市绿化、车辆冲洗、冲厕。本设计采纳 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]：住宅小区；中水回用；膜生物反应器The Engineering Design Of Reuse Project Of Intermediate Water In a Residential DistrictAbstract :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/T18920-2024).In this design,the reuse water is mainly used for city greening, vehicle flushing, toiletflushing .This design uses MBR technology.The process has such features as technology advanced ,good water quality, steady operation, small floor area, easy to management.Key words: Residential district; Reclaimed Water Reuse ; membrane bioreactor目录精品文档---下载后可任意编辑引言.......................................................11 中水回用工程概述..........................................111.1.1 中水概念及应用 111.1.3 生活小区中水的水源及特点 11.2 中水的利用可行性分析.........................................
