Internal Reflux Ratio Control Method Based on Ammonia Nitrogen Regulation and Its Application Benefit Analysis

YIN Xiwu’，XIA Liang²，YUANWeibo² （1.NanjingTofangWaterCo.LdubeiBranch，Huaian30Cina;ofangWaterGroupCo，Ld.，anjngCina） Abstract： In response to the operational requirements of the A2/0 wastewater treatment plant under strict total nitrogen discharge standards，amethodforcontrolingtheinternalrefluxratiobasedonammonianitrogen indicators wasproposed， anditsapplicationbenefitswereanalyzed.Theresultsshowthatcomparedwiththetraditionalmethod，thismethodreduces theinternal reflux ratio by approximately 151% ，the amount of chemical oxygen demand required for each removal of total nitrogen is about 4mg/L ，and the annual electricity consumption is saved by 80800kW⋅h .This method provides an effective solution for wastewatertreatment plants tooperateunder strictdischarge standards with energy conservation and cost reduction.
