The slag slow cooling circulating water treatment method according to claim 2, characterized in that, The statistical data includes: the temperature-time variation curve over the past second preset period; the determination of the target processing strategy based on the statistical data includes: The maximum and minimum temperature thresholds of the slag slow-cooling circulating water are determined based on the temperature-time change curve. When the temperature of the slag slow cooling circulating water is greater than the maximum temperature threshold, the target treatment strategy is determined to be to use a chiller to treat the slag slow cooling circulating water. When the temperature of the slag slow cooling circulating water is less than the minimum temperature threshold, the target treatment strategy is determined to be to use a heating machine to treat the slag slow cooling circulating water.
