摘　　要：通过投加有机碳源改变进水的碳氮比,考察了不同碳氮比条件下缺氧/厌氧/好氧工艺的脱氮除磷效果。结果表明:在污泥回流比为120%的条件下,当C/N值为7、C/P值为75时,缺氧/厌氧/好氧工艺对污水的脱氮除磷效果最佳,对TP、NH4+-N和TN的去除率分别可达95%以上、98%和67%。By adding organic carbon source to change the influent C/N ratio, the nitrogen and phosphorus removal by the anoxic/anaerobic/aerobic process at different C/N ratios was investigated. The results show that under the conditions of the return ratio 120% , the influent C/N =7 and C/P =75, the anoxic/anaerobic/aerobic process has the optimal removal efficiencies of N and P, and the removal rates of TP, NH4 -N and TN can reach more than 95%, 98% and 67% respectively.
