中文摘要:
      采用ASBR处理高浓度甲醇废水,考察了甲醇的厌氧抑制性,容积负荷和水力停留时间对COD去除率的影响,及不同负荷下甲醇代谢途径的变化.试验结果表明,甲醇浓度在3 000~30 000 mg.L-1内对ASBR系统无厌氧抑制性;系统的最佳COD容积负荷为4.6~9.1 kg.m-3.d-1.甲醇的代谢途径对COD的去除率有很大影响,乙酸代谢速率随负荷的提高而升高.当容积负荷小于8 kg.m-3.d-1时,乙酸代谢速率占整个甲醇代谢速率的不到5%,COD去除率达95%以上;当容积负荷为12 kg.m-3.d-1时,乙酸代谢速率为15.8%,处理效率下降为78%.
英文摘要:
      Anaerobic treatment of high concentration methanol wastewater was studied using an anaerobic sequencing batch reactor(ASBR).The anaerobic inhibition of methanol,the effects of volume load and HRT on the treatment efficiency,and the metabolism variation of different methanol load were studied in the experiment.The results of the anaerobic inhibition experiment showed that the activity of methanogenic bacteria wouldn't be inhibited by methanol wastewater when the concentration of COD ranged from 3 000 to 30 0...
