摘　　要：随着蒸发冷却空调系统的持续运行,其喷淋循环水不断蒸发,水质变差,易出现填料结垢、喷嘴堵塞等问题。本文采用阳离子交换树脂法对兰州某地铁站蒸发冷却空调系统喷淋循环水进行处理,水质测试结果表明,处理后的喷淋循环水硬度降低,其中总硬度减少率为65.74%,钙硬度减少率为68.14%,能够满足蒸发冷却空调喷淋循环水质要求。With the continuous operation of the evaporative cooling air-conditioning system,the spray circulating water continues to evaporate,and the water quality deteriorates,which are prone to cause the problems such as fouling of fillers and clogging of nozzles.The cation exchange resin method is used to treat the spray circulating water of the evaporative cooling air-conditioning system of a subway station in Lanzhou,and a water quality test is conducted.The result shows that the hardness of the spray circulating water after treatment is significantly reduced,and the total hardness reduction rate is 65.74%.The calcium hardness reduction rate is 68.14%,which can meet the water quality requirements of the evaporative cooling air-conditioning spray cycle.
