This invention relates to the field of waste liquid treatment equipment, specifically to a waste liquid treatment device for selenium disulfide detergent processing, comprising: a tank and a steam heat exchanger tube assembly. This invention, by setting up a graded treatment mechanism and other components, uses coarse and fine filter plates to divide the interior of the tank into upper, middle, and lower heat zones. In conjunction with the steam heat exchanger tube assembly, concentrated heating in the middle zone naturally forms a vertical temperature gradient within the tank. Under this gradient, impurities of different forms in the waste liquid are classified and isolated in their corresponding temperature zones, avoiding the problem of soft and hard impurities forming stubborn composite scale layers in traditional one-pot treatment methods. This device achieves graded demulsification and step-by-step filtration of selenium disulfide detergent waste liquid within a single tank, ensuring that impurities in each zone are treated in their most easily removable form. This solves the technical contradiction of incomplete demulsification and the inability to simultaneously achieve secondary emulsification in traditional single-temperature treatment, while significantly reducing the cleaning difficulty of the heat exchanger tubes and filter plates.
