摘　　要：SCAL型间冷系统的循环废水中含有大量铁铝腐蚀产物,根据间冷循环水的水质特点,通过理论分析拟定了回收方案,通过工业实验对其进行了验证。结果表明,实施回收前需要对废水的温度、pH值、浊度和铁铝含量进行测定,当循环废水的水质指标不能满足水处理设备进水要求时,需要按照一定的比例将间冷循环废水和厂区生水在生水箱中混合后再进行回收处理。Comparing with raw water,the circulating water in SCAL indirect air-cooling system contained much corrosion products of steel and aluminum.By theoretical analysis the recovery scheme was made up according to the water quality of indirect air-cooling circulating water.Then it is verified by the industry tests.The results indicates the temperature,pH,turbidity and content of Fe and AL of waste water should be measured before recycling.In case some water quality indexes of waste water could not satisfy the water inlet requirements of watertreatment equipment,mixing the raw water and waste water by a ratio could solve this problem.
