  • 摘要: 对预先经过生化工艺处理过的PU合成革废水,进行了组分全分析,发现其总氮的主要存在形式为硝酸盐氮,其浓度高达285 mg/L的浓度水平。采用A/O-MBBR-MBR组合工艺对PU合成革废水生化出水进行了处理。结果证明,其对硝酸盐氮氨氮和COD的平均去除率为55.2%、51.0%和91.2%,具有较好的脱氮能力,是一种PU合成革废水的合适组合工艺。
    Abstract: A biochemical process, named combined A/O-MBBR and MBR, was used to treat the PU synthetic leather wastewater.The results demonstrated that about 55.2% percent of nitrate nitrogen is removed efficiently, and it is effective in the treatment of PU synthetic leather wastewater, which total nitrogen is composed mainly of nitrate.
