摘　　要：针对污水管道混凝土结构受微生物腐蚀问题,利用电化学技术将铜复合物沉积到混凝土表面,赋予其抗腐蚀性;通过电沉积试验、微生物抑制试验,使用平板菌落计数法,分析沉积时间和电流密度对复合铜膜沉积效果和混凝土抑菌性能的影响。结果表明,混凝土经过电沉积技术处理具有良好的杀菌能力,样本抑菌率均超过70%。抑菌效果随沉积时间及电流密度的增加而提升,当电流密度为5 A/m^(2)、沉积时间为5 d时试件的抑菌率可达89.5%。This paper addresses the issue of microbial corrosion in concrete structures within sewage engineering by deploying electrochemical technology to deposit copper compounds on the concrete surface,thereby providing anti-corrosive properties.Through electrodeposition experiments and microbial inhibition tests using the plate colony counting method,we analyze the impact of deposition time and current density on the efficiency of copper composite film deposition and the antibacterial performance of concrete.The findings indicate that the electrodeposition technique exhibits robust antibacterial capabilities,with all samples achieving an inhibition rate exceeding 70%.The effectiveness of antibacterial action increases with longer deposition times and higher current densities,reaching an inhibition rate of 89.5%at a current density of 5 A/m^(2) after 5 days of deposition.
