【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%。更多还原

【Abstract】 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,NH+4-N and TN can reach more than 95%,98% and 67% respectively.更多还原
