城镇污水处理厂进水碳源利用潜力及分配策略探究

Exploring the Potential and Allocation Strategies of Carbon Source Utilization in Urban Sewage Treatment Plants

我国城镇污水处理厂存在总氮不稳定及总氮浓度超标等问题,而这些问题的出现主要是由于进水中有机碳源不足所导致的。由于传统污水处理厂在进行初沉池的设置时存在对非溶解性有机物拦截效果不佳的情况,所以会造成非溶解有机物质进入生物处理单元中,会直接增加二级生物处理单元负担,导致水厂运行成本过高,进而形成恶性循环。为解决这些问题,城镇污水处理厂开始加大对进水碳源利用潜力的研究力度,并对碳源分配方式方法展开了深度探讨。以某城镇污水处理厂为例,对城镇污水处理厂进水碳源利用潜力及分配策略展开全方位探讨,希望能够为我国城镇污水处理厂改进和发展提供一些参考。

There are problems with unstable total nitrogen and excessive total nitrogen concentration in urban sewage treatment plants in China,which are mainly caused by insufficient organic carbon sources in the inflow.Due to the poor interception effect of non-dissolved organic matter in the setting of the initial sedimentation tank in traditional sewage treatment plants,it can cause the problem of non-dissolved organic matter entering the biological treatment unit,directly increasing the burden on the secondary biological treatment unit,resulting in the high operating costs of the water plant and then forming a vicious cycle.To address this issue,urban sewage treatment plants have increased their research efforts on the utilization potential of influent carbon sources and conducted in-depth discussions on carbon source allocation methods.The article will take a certain urban sewage treatment plant as an example to comprehensively explore the utilization potential and allocation strategies of the influent carbon source in urban sewage treatment plants,hoping to provide some reference for the improvement and development of urban sewage treatment plants in China.
