The invention relates to a water circulation treatment method for a re-brushing unit in a pickling section. The method comprises the following steps: acquiring the running state of each device in a pickling and rolling line; a condensate water tank is used for supplementing water to each filtering system; a desalted water tank is used for supplementing water to each filtering system; and pipe network desalted water is used for supplementing water to each filtering system. According to the water circulation treatment method for the pickling section heavy brushing unit, condensate water and desalted water are recycled and reused, and environment protection is better facilitated. 本申请涉及一种酸洗段重刷机组水循环处理方法，所述方法包括步骤：获取酸轧线中各设备运行状态；使用冷凝水罐对各过滤系统进行补水；使用脱盐水罐对各过滤系统进行补水；使用管网脱盐水对各过滤系统进行补水。本申请提供的一种酸洗段重刷机组水循环处理方法实现了冷凝水和脱盐水的回收循环再利用，更有利于保护环境。
