基于“双碳”目标的城镇污水厂优化应用研究

Research on the Optimization and Application of Urban Wastewater Treatment Plants Based on the“Dual Carbon”Target

通过在主反应区增设搅拌器,考察生化池在闲置/进水阶段在增加搅拌的作用下的处理效果,结果表明,增加搅拌60 min的TN、TP的平均去除率分别为59%、94%,脱氮除磷效果最好,可优于提标改造后的一级A工艺出水水质,并且去除率在第10 d后开始趋向稳定,出水都达到一级A标准要求。本研究为相关污水处理厂优化调控,低碳运营,提供了可供借鉴、参考的案例。

Through installing agitator in the main reaction zone,to investigate the treatment effect of the biochemical pool under the effect of increasing agitation in idle/influent stage.The results showed that the removal rate of pollutants can be better than that of grade a process after upgrading,and after stirring for 60 minutes,the average removal rate of TN and TP was 59%and 94%,respectively,which the effect of nitrogen and phosphorus removal was the best.The removal rate tended to be stable after the 10th day,and the effluent reached the requirements of grade A standard.This study provides a reference case for optimizing regulation and low-carbon operation of relevant sewage treatment plants.
