| 摘 要： | 就C/N对Carrousel 2000氧化沟同步脱氮除磷的影响进行了研究。结果表明，进水C/N值在5～13之间时，进水C/N不影响氧化沟系统对NH3-N的去除效果。出水NH3-N浓度＜1 mg/L，平均去除率达到97.40%。当C/N低于11时，TN、TP的去除率随C/N的升高而快速大幅提高，分别从5时的26.47%和14.99%升至11时的93.48%和97.03%。当C/N＞11时，氧化沟TN去除率达到93.48%，TP去除率接近100%，氧化沟具有了良好的同步脱氮除磷的效果，出水水质满足国家《城镇污水处理厂污染物排放标准》(GB 18918-2002一级A标准)要求。TP去除率与TN去除率相关系数R2＝0.985。

| Abstract: | The effect of C/N ratio on simultaneous nitrogen and phosphorus removal in Carrousel 2000 oxidation ditch was studied.The experimental results show that when the influent C/N ratio was between 5 and 13,ammonia nitrogen removal efficiency in oxidation ditch was not affected by influent C/N ratio.The ammonia nitrogen concentration in the effluent was below 1 mg/L,the average removal rate was 97.40%.When influent C/N ratio was lower than 11,TN and TP removal rates increased sharply as C/N ratio increased,from ... |
