城市污水处理现状及污水处理厂提标改造

The Current Situation of Urban Sewage Treatment and the Upgrading and Renovation of Sewage Treatment Plants

污水处理厂提标改造不仅是污水处理厂可持续发展的需要,也是减少城市污染物排放、回用再生水资源的需要。基于此,简单介绍了城市污水处理现状,从设施设置、设施脱氮除磷效率等方面,分析了城市污水处理存在问题的原因,以A2O池+MBR池+反硝化滤池+转盘滤池为重点,提出了污水处理厂提标改造的方案与成效,以期为城市污水处理效果的提升提供参考。

The upgrading and renovation of sewage treatment plants is not only necessary for their sustainable development,but also for reducing urban pollutant emissions and reusing recycled water resources.Based on this,the current situation of urban sewage treatment is briefly introduced,and the reasons for the problems in urban sewage treatment are analyzed from the aspects of facility settings,denitrification and phosphorus removal efficiency.With a focus on A2O tank+MBR tank+denitrification filter+rotary disc filter,a plan and effectiveness for upgrading and renovating sewage treatment plants are proposed,in order to provide reference for the improvement of urban sewage treatment efficiency.
