降雨量对污水处理一体化设施运行效果的影响研究

Research on the Influence of Rainfall on the Operation Effect of Integrated Sewage Treatment Facilities

作为污水处理的终端,污水处理一体化设施的运行稳定性受到前端设备的影响,雨污合流管网下,雨水冲击使污水处理设施在雨季运行难度加大。本文以23座污水处理一体化设施为研究对象,分析不同降雨量下的进水处理负荷、进水化学需氧量(COD_(Cr))、进水氨氮浓度、出水COD_(Cr)、出水氨氮浓度、COD_(Cr)削减量、氨氮削减量等指标,明确降雨量对污水处理一体化设施水质水量及运行效果的影响,以提高系统运行稳定性,保证出水质量达标。

As the terminal of sewage treatment,the operational stability of integrated sewage treatment facilities is affected by front-end equipment,under the combined rainwater and sewage pipeline network,the impact of rainwater increases the difficulty of operating sewage treatment facilities during the rainy season.Taking 23 integrated sewage treatment facilities as the research object,this paper analyzes the influent treatment load,influent chemical oxygen demand(COD_(Cr)),influent ammonia nitrogen concentration,effluent COD_(Cr),effluent ammonia nitrogen concentration,COD_(Cr) reduction,ammonia nitrogen reduction,and other indicators under different rainfall conditions,and clarifies the influence of rainfall on the water quality,quantity,and operational effect of the integrated sewage treatment facilities,in order to improve the system’s operational stability and ensure that the effluent quality meets the standard.
