Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to the figure, in the embodiment of the utility model, an industrial wastewater treatment device includes a housing 1 and a hydraulic cylinder 5; the top of the housing 1 is communicated with a water inlet pipe 11, and a booster valve 12 is installed on the water inlet pipe 11 , the booster valve 12 increases the pressure of the water inlet, and a water separator 13 is arranged directly below the water inlet pipe 11. The water separator 13 is fixed on the inner wall of the housing 1 through a support frame 16, and the water separator 13 is a circular platform structure. Its material is stainless steel, and the diameter of the upper end of the water separator 13 is smaller than the diameter of the water inlet pipe 11. Several protrusions can also be arranged on the water separator 13 to enhance the water separation ability. On the device 13, the sewage is impacted into water droplets, which are evenly scattered into the housing 1; a horizontal filter plate 6 is provided below the water separator 13, and the mesh diameter of the filter plate 6 is 1 to 2 mm.
