某高校污水处理及再生回用工程

Treatment and Reuse of Sewage from a University

某高校污水处理及回用工程处理原水为宿舍楼的生活污水以及浴室洗浴污水,将两种污水单独收集处理,主体处理工艺分别采用循环式活性污泥工艺和生物接触氧化工艺。运行结果表明,出水水质可满足《城市污水再生利用城市杂用水水质》(GB/T 18920—2002)中城市绿化、道路清扫和冲厕的要求,不仅能减少COD排放量,节约大量新鲜水,达到环境效益和经济效益并收的效果;而且处理设施灵活多变,为该校环境工程专业师生提供了很好的教学和科研平台。

The raw water included the domestic sewage from dormitory building and the sewage from bathroom in the sewage treatment and reuse project in a university. Two kinds of sewage were col- lected and treated separately. Cyclic activated sludge system and biological contact oxidation process were adopted. The result showed that the effluent quality could meet the requirements for greening, road wash- ing and toilet flushing in the Reuse of Urban Recycling Water--Water Quality Standard for Urban Miscella- neous Water Consumption （GB/T 18920 -2002）. The discharge amount of COD was decreased, a large quantity of fresh water was saved, obvious environmental benefit and economic benefit were achieved. Besides, the project was flexible and provided a teaching and scientific research platform for the teachers and the students in environmental engineering department.
