中水腐蚀特性试验与分析

Experiment and analysis on the corrosion characteristics in reclaimed water

通过循环水动态试验和有关金属材料腐蚀速度的测量、分析,介绍了以电厂污水、废水和城市二级排放污水为水源,混合并经过深度处理后的中水作为循环水补充水时可达到稳定的最大浓缩倍率,以及对系统中金属材料的腐蚀特性,为循环水系统的安全稳定运行提供了依据。

The secondary municipal effluent mixed with sewage water and waste water discharged from power plant itself has been used as the water source of circulating supplement water after deep treatment by lime. According to the dynamic test for the circulation cooling water and the corrosion speed measurement of related metallic materials, the maximum stable concentration ratio which can be achieved was introduced, and the characteristics of metal corrosion was described. The conclusions have been approved by applied in the circulation water system for safe and stable operation.
