城市粪便集中处理对合肥市污水处理厂的影响
|
摘要
分析了我国城市粪便集中处理的现状,着重探讨了城市粪便集中处理的规模、处理深度等对污水厂处理效果的影响,并结合实例指出污水处理厂的规模、性质以及生化处理工艺等条件决定了粪便集中处理场的位置、规模和处理程度。采用初级、二级处理工艺的粪便集中处理场应配套建在以工业废水处理为主的污水处理厂附近,以实现粪便资源化和城市污水处理厂的达标运行。
The present situation of centralized treatment of urban excrement in China is analyzed,and the influence of the treatment scale and degree of urban excrement on wastewater treatment plant is discussed.Combined with an example,it is pointed out that the position,scale and degree of centralized excrement treatment field are determined by the scale,nature and biochemical treatment process of wastewater treatment plant.The centralized excrement treatment field using primary or secondary treatment process should be constructed near the industrial wastewater treatment plant,which can realize excrement resource reuse and the up-to-standard operation of municipal wastewater treatment plant.
