回收RO浓排水和煤矿井排水用于循环冷却水

Experience and economic profit of the cooling water system using wastewater as make-up water

通过回收反渗透浓排水和煤矿井排水用于电厂循环冷却水补充水的1a运行结果,介绍了完全使用工业排水作为循环冷却水,并在较高的浓缩倍率下安全、稳定运行的循环水处理方式和运行控制方法的实际经验。依据改造运行1a后的节水和运行成本表明,实施该项节水技术改造后,电厂的生产成本明显降低,具有显著的经济效益和社会效益。并提出进一步挖掘节水潜能的可能性。

In this paper working conditions of cooling water using industrial wastewater as makeup water is described in detail. The results show that the cooling water system runs well when fully using industrial wastewater as makeup water, and the expected profit is attained a year later. Furthermore, the possible measures of reducing the cost of water system are discussed.
