摘要
在9L、4格室的厌氧折流反应器(ABR)中,处理以葡萄糖为共基质的含硝基苯废水,温度为5～10℃,进水COD浓度为200～400mg/L,HRT为3h。结果表明ABR对有毒废水浓度变化的适应能力强,当进水硝基苯的浓度为0.48mg/L时,出水COD在21天恢复正常,运行稳定,反应器经硝基苯连续3天冲击(0.48mg/L)后,经历了原有微生物死亡、新微生物生长直到最终顶级群落和稳定发酵类型的形成的过程。
A 9 liter anaerobic baffled reactor （ABR）,with four compartments,was used to treat wastewater containing glucose nitrobenzene （NB）.The reactor was operated at temperature of 5-10 ℃,HRT of 3 h and the influent COD of 200--400 mg/L,for 2 months.It was found that ABR was able to adapt to the nitrabenzene load.The effluent COD recover in 21 days when the influent nitrobenzene with the concentration of 0.48 mg/L. Experienced the original microorganism death,the new microorganism grew until the final top community and the stable fermentation type formation process.
