  • 摘要: 将厌氧折流板反应器（ABR）与膜生物反应器（MBR）组合的新型CAB-MBR反应器用于处理生活污水，进行亚硝化的启动研究。研究期间，温度为20~28℃，在HRT 为7.5 h、混合液回流比R1和R2分别为200%和100%，DO为1 mg/L的条件下，启动运行了50 d，系统稳定后，NO2-出水浓度在4 mg/L以上，NO2-占NOx-总量的90%，短程反硝化效果良好。对 COD、NH4+-N、TN 和TP 的平均去除率分别为 94%、90%、75%和 80%，出水平均浓度分别为 25、3、9.5和0.7 mg/L。
    Abstract: The start-up on nitrification was researched in the combined anaerobic baffled-membrane reactor that was applied to treat domestic sewage. Under the conditions of temperature of 20~28℃, HRT of 7.5 h, two mixed-liquor return ratio of 200% and 100%, respectively and DO of 1 mg/L, the start-up of the combined system was operated for 50 days, the effluent concentration of NO2- was higher than 4 mg/L in the stable system, while NO2- was accounted for 90% of total NOx-. The results indicated that there was a good effect of short-cut denitrification in the combined system. In addition, the average removal rates of COD, NH4+-N, TN and TP were 94%, 90%, 75% and 80% in the stable system, respectively. And the average effluent concentrations of them were 25, 3, 9.5 and 0.7 mg/L, respectively.
