白龙港污水处理厂合流污水分流设施改造

Reconstruction of Combined Sewage Distribution Facilities in Bailonggang WWTP

对合流制污水进行一级以上处理再排江是减少污染物排放的有效方法。但合流制排水系统污水水量变化幅度大,对于合流制污水处理厂,如何从时刻变化的合流污水中分离出稳定的水量进入后续的分级处理系统是个难题,也是减少对生化处理工艺冲击,确保达标排放的关键。该文结合白龙港污水处理厂的配水渠改造提供合流制水量稳定分流的实例,可供参考。

To implement the primary treatment and over of the combined sewage before discharged into rivers is an effective method to reduce the pollutants. However, the sewage flow varying scope of the combined sewage system is large. As for a combined sewage treatment plant, it is a difficult how to separate the stable flow from the combined sewage that varies drastically into the following treatment systems. Meanwhile, this is also the key to reduce the impact on the biological reaction process and ensure the discharging standard. The article provides a practical example how to separate the stable separated flow from the combined sewage on the reconstruction of the distribution channels of Bailonggang WWTP able to be for reference.
