For chemical wastewater with a large solid content, the following problems exist when the method is used for removing solids in the chemical wastewater: when the push plate 50 moves closer to the discharge chute 22, solids accumulate between the push plate 50 and the wall of the solid-liquid separation casing 23 to which the hydraulic cylinder 40 is attached. In order to solve the above problem, a barrier filter sheet 24 is provided at the water inlet end of the separation filter cartridge 21, one end of the barrier filter sheet 24 is hinged to the inner wall of the solid-liquid separation casing 23, and the other end of the barrier filter sheet 24 is detachably connected to one end of the pulling rope 26. In order to pull up the barrier filter sheet 24, the other end of the pulling rope 26 is detachably connected to a fixed pulley 27, and the fixed pulley 27 is attached to an output shaft of the elevator motor 25. When the filter plate 24 for the partition is pulled up, the filter plate 24 for the partition separates the water outlet end of the water inlet pipe 10 from the water inlet end of the separation filter cartridge 21, so that the situation that solids are accumulated between the push plate 50 and the wall of the solid-liquid separation housing 23 provided with the hydraulic cylinder 40 when the push plate 50 moves to approach the discharge cylinder 22 can be avoided.

And a water collecting structure is arranged on the wall of the cleaning shell close to the water outlet end of the cleaning shell, wherein the water collecting structure is a conical groove, and the water outlet end of the cleaning shell is arranged on the bottom of the conical groove. When the washing shower nozzle 33 sprays the reuse water to the solids in the washing filter cartridge 31, the filtrate is collected by the water collecting structure and discharged through the second drain pipe 70. The inclined wall of the filter cylinder 31 for cleaning can facilitate the solid to move to the discharge port of the filter cylinder 31 for cleaning along the wall of the filter cylinder 31 for cleaning, and the reuse water sprayed on the solid can flow along the inclined direction, so that the retention time of the reuse water on the solid is prolonged, and the reuse water is beneficial to washing off the residual pollutants on the solid, thereby reducing the attachment amount of the pollutants on the solid and reducing the damage of the pollutants to the health of operators in the subsequent treatment link of the solid.
