摘要
随着城市的发展和人民生活水平的提高,城市污水排放量日益增大,且污水成分日趋复杂,迫切需要适应各地经济发展和环境保护目标的污水处理技术。本文重点介绍了城市污水生物处理技术之一活性污泥法中的4种污水处理工艺,同时介绍了曝气生物滤池污水处理方法,并对组合技术处理城市污水进行了展望。
With the development of urbanization and the improvement of people＇s living levels,the quantity of municipal wastewater is increasing, and the composition is complicated, so different kinds of treatment techniques are needed urgently according to different objects of economical development and environmental protection. This paper emphasized four kinds of wastewater treatment techniques of activated sludge methods , and introduced biological aerated filters, at the same time gave some expectation to the combined wastewater treatment techniques.
