摘要
目前国内新建污水厂在投产后普遍存在水量、水质变化大的问题,在工艺控制上存在诸多困难,往往能耗较高。以石井污水处理厂的曝气沉砂池进出水为研究对象,主要分析了曝气沉砂池的预处理对COD去除效果的影响,并通过对工艺的合理调控,做到资源的最大化利用。该厂采用具有脱氮除磷功能的改良A/A/O工艺。
At present, there are some issues such as great changes of water quantity and quality in the new-built wastewater treat- ment plant, which is difficult for treatment process control and causes high energy consumption. This study mainly analyzed the effect of pre-treatment in aerated grit chamber on COD removal efficiency. The actual influent and effluent from aerated grit chamber of Shijing Wastewater Treatment Plant was investigated. The goal was to realize maximization of resources through reasonable process control. This plant adopted improved A/A/O treatment process with the function of nitrogen and phosphorus removal.
