摘　　要：排海管线是绍兴水处理公司处理后尾水向钱塘江排放的通道,管道铺设在地下。为延缓管道腐蚀的发生,延长管道使用寿命,在排海管线上采用了阴极保护系统。采用强制电流法阴极保护设计,在外排泵房处建设一座阴极站。调试结果表明,阴极保护系统的恒电位仪、深井阳极及绝缘法兰安装质量优良,系统工作稳定正常。最后对阴极保护系统的后续运行管理进行了介绍。Marine ouffall pipeline is a channel discharging the effluent from Shaoxing Sewage Treatment Plant into Qiantang River. The pipeline is laid in the ground. To control pipeline corrosion and prolong the service life of pipeline, the cathodic protection system was used on the sea discharge pipeline. A cathodic protection station was built at the discharge pump room using impressed current cathodic protection system. The commissioning results showed that the potentiostat, deep well anode and insulation flange of cathodic protection system were installed well, and the system worked steadily. The subsequent operation management of cathodic protection system was introduced.
