1、大学学生公寓洗漱废水回用分析与探讨摘要：随着高校的扩招，校区人员的增多，高校已经成为城市用水大户，水质成分简单，易于处理的特点，非常适合建设中水回用系统。中水回收利用是污水资源化的一种重要方法，在高校区启用中水回用系统，对我国的环境保护、水资源保护、水污染防治、经济可持续发展都起到了至关重要的作用，具有明显的经济效益、社会效益和环境效益。参考了国内外高校中水回用实例，本文利用序批式活性污泥工艺(SBR)处理甘肃农业大学18#学生公寓楼洗漱废水的工艺流程、特点、主要构筑物设计参数及主要的技术经济指标，在技术经济上做了可行性分析。该工
2、艺对洗漱废水中COD,BOD,SS有较高的去除率,处理后出水用于学生公寓冲厕,其水质符合中华人民共和国《生活杂用水水质标准》(GJ／T48--1999)回用水标准的要求。该项技术由于设备形体小、工艺单一，原管道改变不大，因而便于改建施工。关键词：中水回用；洗漱废水；高校；公寓楼WashingwastewaterreuseanalysisanddiscussionatGansuAgriculturalUniversity—Takinganexampleofstudent，apartment18#buildingsWANGQiaofa
