Experimental Study of the Denitrification Effects by Use of SBBR Process with Sodium Acetate as an Extra Carbon Source

  • 摘要: 试验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,去除率为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",出水可作为回用水。
    Abstract: In this experiment, sodium acetate was selected as an extra carbon source and SBBR process was used to treat the urban domestic sewage with low C/N ratio. When the C/N ratio increased to be 7.0 after addition of carbon source, the highest removal rate of NH4+-N in the raw water was 89.31%. When the C/N ratio increased to be 7.12 after addition of carbon source, the removal efficiency of TN was best as 71.27%. The results showed that with sodium acetate as the extra carbon source, the performance of SBBR process for denitrification of the domestic sewage was quite well. Indicators of the water quality of the effluent all complied to level A regulated in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB18918-2002) and therefore the effluent could be reused.
