  • 摘要: 考察了膜电解氢自养膜生物反应器在不同水力停留时间(HRT)和电流强度下对饮用水中ClO4-的去除效果。结果表明,在进水ClO4-浓度和电流强度分别为10 mg/L和300 mA的情况下,HRT从12 h降低到4 h,反应器出水ClO4-浓度随HRT的降低呈增大趋势,但运行稳定后去除率均维持在99%以上,出水pH较进水有所增大,但增加幅度随HRT的缩短而减小。当电流强度从100 mA增加到200 mA时,出水ClO4-浓度随电流强度的增大而减小,稳定运行后出水ClO4-浓度低于4μg/L,出水pH受电流强度变化的影响不大。整个运行过程未检测到中间产物ClO3-和ClO2-的存在。
    Abstract: The perchlorate removal of drinking water in a membrane electrolytic hydrogen autotrophic membrane bioreactor was investigated under different hydraulic retention times(HRTs) and current intensity. The results showed that when the infulent ClO4- concentration and the current intensity were 10 mg/L and 300 mA, respectively, the effluent ClO4- concentration increased with the decrease of HRT from 12 h to 4 h. However, the removal efficiency of ClO4- was more than 99% under the steady states. The pH of effluent was higher than the influent pH, whereas the increased content of pH decreased with the decrease of HRT. The effluent ClO4- concentration decreased with the increase of current intensity from 100 mA to 200 mA, and the effluent ClO4- under the steady states was below 4μg/L. The effluent pH was not remarkably affected by the change of current intensity. No ClO3- or ClO2- was detected during the whole operational process.
