摘　　要：采用电镀法,考察Cu 2+浓度、电流密度、电镀时间对镀层形貌及电镀速率的影响,以SEM-EDS、XRD、CV等分析方法对所获得的铜电镀污泥碳进行表征;并进一步制备三元微电解陶粒,考察不同加铜方式对陶粒性能的影响。结果表明:在Cu 2+浓度为0.15 mol/L、电流密度为12.5 mA/cm 2时镀层均匀、致密;铜电镀掺杂制备的三元微电解陶粒对硝基苯废水的降解有更高的去除效果,在初始pH为3且废水中的硝基苯浓度为100 mg/L时,反应180 min即可达到90.61%的硝基苯去除率,且对硝基苯的降解符合伪一级动力学反应,反应速率常数可达到0.01058 min-1。The effects of copper ion concentration,current density and plating time on the morphology of plated layer and the plating rate were investigated by plating method.Characterization of copper-loaded sludge carbon was conducted through SEM-EDS,XRD,CV test methods.The ternary micro-electrolysis ceramic pellets were further prepared to investigate the effect of different copper addition methods on the performance of ceramic pellets.The results showed that the plated layer was uniform and dense when the copper ion concentration was 0.15 mol/L and the current density was 12.5 mA/cm 2.The ternary micro-electrolysis ceramic pellets prepared by copper electroplating mixing has better degradation effect on nitrobenzene wastewater.When the solution pH is 3,the concentration of nitrobenzene is 100 mg/L and the reaction time is 180 min,the removal rate of nitrobenzene by the filler is 90.61%,and the degradation of nitrobenzene was in accordance with the pseudo primary kinetic reaction,with a reaction rate constant of 0.01058 min-1.
