【摘要】 以模拟废水中的四环素（TC）和TOC（总有机碳）去除率为研究指标,探讨粒子电极的不同体系对降解四环素废水的影响。同时以浸渍法优化制备不同负载型γ-Al₂O₃粒子电极,并研究了其电催化性能和降解能耗,考察浸渍法和后浸渍法制备粒子电极的优劣。结果表明:三维电解体系对TC的降解效果达到40.1%,明显优于二维体系的29.1%;不同负载型粒子电极对TC的降解效果依次为Bi>Sn/Sb>Ti>Co>Cu>Fe>Mn,其中γ-Al₂O₃-Bi粒子电极对TC和TOC的去除效果最佳,分别为63.8%、36.3%;γ-Al₂O₃-Bi和γ-Al₂O₃-Sn/Sb粒子电极的能耗分别为85.9,90.7 （kW·h）/kg,远低于二维降解体系（205.5 （kW·h）/kg）;浸渍法制得的γ-Al₂O₃-Bi-（Sn/Sb）对TC的电解效率明显优于后浸渍法制得的粒子电极,其中前者为78.9%,高出后者约10百分点。更多还原

【Abstract】 The effects of different systems of particle electrodes on the degradation of tetracycline wastewater were studied based the removal rate of TC（tetracycline） and TOC（total organic carbon） in simulated wastewater as the research indexes. Simultaneously, different supported γ-Al₂O₃ particle electrodes were optimized and prepared by impregnation method, and their electro-catalytic properties and degradation energy consumption were investigated, and finally, the advantages and disadvantages of impregnation method and post-impregnation method in preparing particle electrodes were studied. The experimental results showed that the degradation effect of TC by the three-dimensional electrolysis system reached 40.1%, which was obviously better than 29.1% of the two-dimensional electrolysis system; the TC degradation effect by different supported particle electrodes was in order of Bi> Sn/Sb> Ti> Co> Cu> Fe> Mn, with γ-Al₂O₃-Bi particle electrodes having the best removal effect of TC and TOC, which were 63.8% and 36.3%, respectively; the energy consumptions of the γ-Al₂O₃-Bi and γ-Al₂O₃-Sn/Sb particle electrolysis were 85.9（kW·h）/kg and 90.7（kW·h）/kg respectively, which were far below that of the two-dimensional degradation system（205.5（kW·h）/kg）; in addition, the electrolysis efficiency of γ-Al₂O₃-Bi-（Sn/Sb） particles prepared by impregnation method was obviously better than that by the post-impregnation method, with the former（78.9%） being about 10% higher than the latter.更多还原
