Abstract： To investigate thetechnical pathway for upgrading sewage treatment plants underlow-carbon，highnitrogen， and high phosphorus water qualityconditions，this study explores thecombined application of Moving-Bed Biofilm Reactor （MBBR）oxidation ditch and deep treatment processes，analyzing the operational efectiveness of a three-stage control strategy comprising“biological enhancement （MBBR media addition） + chemical synergy （high-efficiency sedimentation tank） + deep filtration （denitrification deep-bed filter）.Results indicate that post-upgrade efluent massconcentrations of Chemical Oxygen Demand （COD）， NH 3 -N， Total Nitrogen （TN），and Total Phosphorus （TP） averaged 45，1.2， 12，and 0.3mg/L ，respectively，consistently meting Grade 1A discharge standards.The operating cost percubic meter of water was reduced to O.85 yuan，and the oxygen utilization rate was increased to 25% ：
