| 摘 要： | 选取乙酸钠为外加碳源,采用SBBR工艺处理低C/N比城市生活污水。当外加碳源后的C/N比值增加至7.0左右时,对原水NH4+-N去除率最高为89.31%,外加碳源后的C/N为7.12时,TN的去除率最好,为71.27%。结果表明,外加乙酸钠碳源后的SBBR工艺对于低C/N生活污水脱氮性能十分良好。出水水质指标均达到了《城镇污水处理厂污染物排放标准》(GB18918-2002)中的"一级标准A标准",出水作为回用水。

Experimental Study on Denitrification Effect of SBBR With Sodium Acetate as External Carbon Source |
| |
| Abstract: | In this experiment, sodium acetate was used as an external carbon source, and the low C/N ratio domestic sewage was treated by using SBBR. The results show that when the C/N ratio increases to 7.0 after adding carbon source, the highest removal rate of NH4+-N of raw water is 89.31%; and when the C/N ratio increases to 7.12, the removal efficiency of TN is the best,71.27%. SBBR has quite well denitrification performance for the low C/N ratio domestic sewage after adding carbon source. The effluent water as recycle-water conforms to one-class A permitted criteria of“Discharge standard of pollutants for municipal wastewater treatment plant”(GB18918-2002). |
