Abstract: 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.

Key words: circulation cooling water dynamic test, reclaimed water reuse, concentration ratio, metal corrosion, water quality Detection
