摘　　要：由于北方冬季气温较低,因冬季防冻及工艺需加装拌热装置,如果在污水处理系统中安装电拌热装置,不仅能有效的解决系统设备及管道的防冻问题,而且电拌热的运行成本较蒸汽拌热低、使用年限长,维护简单,有很好的使用及推广价值。Thermo-keeping is necessary for anti-freeing and technological aspects in cold winter of northern area.If thermoelectric mix can be used in sewage disposal system, not only can be solved efficiencily equipment and piping anti-freezing problem,but also is beneficial to thermoelectric mix's popularization and application, for the lower operating cost,longer endurance life and simpler maintenance than vapormixing does.
