The invention discloses sewage treatment equipment with a grid mechanism. The sewage treatment equipment comprises a telescopic rod, a sliding block, a tank body, a bottom rod, a discharging opening,a sleeve, a cover, a clamping base, a hydraulic lifting rod, a baffle, a fixing plate, a first motor, a lead screw, a sliding rod, a top plate, a connecting block, a sliding base, a grid, a brush, a moving plate, a stop block, a moving rod, a sliding plate, a T-shaped rod, a turntable and a second motor. A small hole is formed in the center of the bottom end of one side of the tank body, the diameter of the small hole is consistent with that of the baffle, the other end of the hydraulic lifting rod is fixedly connected with the interior of the clamping base in a sleeved mode, the other side, corresponding to the hydraulic lifting rod, of the clamping base is fixedly connected with the center of one side of the cover through a bolt, and the opposite sides of the cover are fixedly connectedwith the outer part of one end of the sleeve through a bolt. The sewage treatment equipment is simple in structure and convenient to use, impurities can be prevented from being manually removed, the labor intensity can be relieved, the grid can be advantageously cleaned by the aid of brush, and the sewage treatment work efficiency can be improved.
