摘要：

近年来，城市生活污水呈现出低碳氮比的趋势，造成污水处理脱氮困难。采用ABR-生物接触氧化工艺对低碳氮比生活污水进行试验研究，确定了试验运行参数，即在进水COD/N为2~7范围内，当HRT=10 h，R=2.5、T=30 ℃时，系统对TN的去除效果良好；TN的平均去除率随着碳氮比的减小而迅速降低，此时，碳源不足成为制约脱氮效果的主要原因；在最佳运行条件下，当进水COD/N为6~7时，TN平均去除率达到80%以上，出水TN质量浓度小于15 mg/L，满足《城镇污水处理厂污染物排放标准》一级A标准。

Abstract:

In recent years, there is a trend of low C/N ratio in municipal domestic wastewater, which results in serious problems of denitrification of wastewater. This paper presents the experimental study on ABR & Biocontact Oxidation Process to treat low C/N ratio domestic wastewater, determines the experimental operating parameters, and the result shows that in the range from 2 to 7 of the COD/N ratio of influent, when HRT=10 h, R=2.5, T=30 ℃, the removal rate of TN shows the satisfactory performance. The average denitrification rate decreases rapidly as the COD/N ratio of influent reduce, which is due to the lack of carbon source. Under the satisfactory operating conditions, when the COD/N ratio of influent is 6-7, the average denitrification rate reaches more than 80%, and the concentration of TN in effluent is lower than 15 mg/L, which meets the first A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant.

Key words: ABR, biocontact oxidation, low C/N ratio, nitrogen removal
