摘　　要：针对三峡库区某污水处理厂长期进水氮磷值偏高、进水碳源不足、脱氮除磷效率低及运行能耗偏高等问题,通过对传统Carrousel氧化沟进行多点进水改造,实施了碳源优化分配及低溶解氧调控。结果表明,改造调控后总氮、总磷去除率分别提高15.43%、14.32%,电单耗下降了20.92%,确保了出水水质稳定达标。To solve the problems of a sewage treatment plant in the Three Gorges Reservoir Area, such as high nitrogen and phosphorus and lack of carbon source in the influent, low nitrogen and phos- phorus removal efficiency and high energy consumption for a long time, the traditional Carrousel oxidation ditch was renovated using step feeding, and the precise distribution of carbon source and low DO control were implemented. As a result, the removal rates of TN and TP were increased by 15.43% and 14.32% respectively, and the unit power consumption dropped by 20.92%, ensuring that the effluent quality met the discharge standard.
