本科毕业设计（论文） 小区生活污水处理与回用设计 学 院 环境科学与工程学院 专 业 环境工程 年级班别 2007级（1）班 学 号 3117008130 学生姓名 胡涛 指导教师 付丰连 2011 年 6 月设计总说明 建筑小区主要是指居住区、疗养院、商业中心、机关学校等具有几种(或一种)功能的、相对独立的区域，其排水系统一般不在城市市政管网覆盖范围之内。小区污水属于生活污水范畴，一般水量较小，在我国通常把小于4000m3/d的污水处理称为小区污水处理。小区污水一般水量、水质变化较大，污染物浓度比城市污水低，可生化性好，因而易于处理，并通过消毒处理可回用，节约水资源。 本设计要求处理水量为500t/d的小区生活污水（以居住小区为背景），设计方案采用序批式间歇活性污泥法（SBR）。SBR技术的核心是SBR反应池，该池集均化、初沉、生物降解、二沉池等功能于一池，无污泥回流系统。 应用序批式活性污泥法工艺，使出水水质达到《城镇污水处理厂新污染物排放标准》（GB18918-2002）标准的要求，并通过消毒回用，达到“零”排放目的。可作为中型楼盘生活污水处理工程的技术参考。 ：小区生活污水，SBR，回用 Community buildings are mainly residential, nursing homes, commercial centers, schools and other institutions have several (or a) functional. relatively independent of the region, And its drainage system is generally not of urban pipe network coverage areas. Community sewage belongs to the urban wastewater, The flux of sewage treatment less than 4000 m3/d is called community sewage treatment. The flux and water quality of community sewage change much and pollutant concentration of community sewage is lower than urban wastewater. The community sewage is in good biodegradability and can be easily dealed with. Then it can be reused by disinfection to save water resources. The design requirements is to treat the 500 t/d water flux of the community sewage (Residential Area background). SBR is the core technology SBR pool, The pool is set, the early Shen, biodegradable, two sedimentation tanks, and other functions in a pool, returning without sludge system. Application of SBR process using water to New Pollutants Emission Standard of Urban Wastewater Treatment Firm (GB18918-2002) and through the use of disinfection to achieve zero emission purposes. This method can provide technical references for the medium-sized flats sewage treatment.
