摘　　要： 含铊酸性废水对人体健康构成严重威胁。试验研究了采用硫酸盐还原生物反应器处理含铊酸性废水的可行性。试验结果表明,采用高负荷培养法可在136天成功启动硫酸盐还原生物反应器。反应器在活性迟滞阶段、活性提高阶段和活性稳定阶段三个阶段对硫酸盐的去除率分别为25.21%、61.08%和93.39%。反应器对COD的处理效果则欠佳,活性稳定后反应器对COD的去除率也仅有26.12%。反应器对铊具有较好的处理效果,平均去除率为97.97%。反应器COD去除量与硫酸盐去除量的比值随着反应器启动进程的推进比值逐渐缩小,且趋于稳定,去除量比值和反应器脱硫效能具有正相关性。 Human health has been great threatened by acid wastewater containing thallium.The feasibility of start-up Sulfate-Reducing Bioreactor with acid wastewater containing thallium had been study in the experiment.Sulfate-Reducing Bioreactor being started up successfully within 136 days with the method of high rate cultivation had been demonstrated.The results showed that the averaged removal efficiencies of sulfate achieved 25.21%,61.08% and 93.39% during the lag phase,the increase phase and the steady phase of the Sulfate-Reducing Bioreactor,respectively.A preferable removal efficiency of thallium had been achieved,corresponding to the averaged thallium removal efficiency of 97.97% during the experimental period.However,COD in the acid wastewater mixture need further treatment due to removal efficiency of COD was not well,corresponding to the averaged removal efficiency of 26.12% in the steady phase of Sulfate-Reducing Bioreactor.The ratio of removal COD to sulfate reduced gradually and tented to be steady with the advance of start-up process of the bioreactor,which had been demonstrated that positive relevance was existed between the ratio of removal COD to sulfate and sulfate removal efficiency of the bioreactor.
