Sewage purification device

Abstract

The invention provides a sewage purification device used for removing impurities in sewage, and belongs to the technical field of environmental protection equipment manufacturing. The sewage purification device comprises a frame body, wherein a water storage container with an upward opening is arranged on the frame body, a filter box with an upward opening and a filter screen on one side face is arranged in the water storage container, a vertical solid impurity pushing device is arranged on the inner bottom wall of the filter box, a horizontal solid impurity pushing device matched with the vertical solid impurity pushing device is arranged at the opening of the filter box on the water storage container, an air plate is arranged at the position, corresponding to the filter screen, of the side wall of the water storage container, a clear water outlet, an inclined plate, a medicine injection pipe with a switch valve and an emptying valve are sequentially arranged at the position, below the filter box, of the side wall of the water storage container, and a stirring device is arranged below the filter box in the water storage container. According to the invention, the problems that solid impurities and flocculation precipitation are not integrated at present, the solid impurities on the filter screen cannot be automatically removed, and filter holes of the filter screen are easily clamped by the solid impurities in the sewage filtering process are solved.

Description

technical field [0001] A sewage purification device is used for removing impurities in sewage and belongs to the technical field of environmental protection equipment manufacturing. Background technique [0002] In the process of sewage treatment, many processes are required. First, the solid impurities in the sewage should be removed, and then flocculants are added to precipitate other harmful substances in the sewage, and finally clear water is obtained. However, these two processes in the prior art They are all separated, making it necessary to flow sewage into the device for removing solid impurities during use, and then carry out flocculation and sedimentation, which increases equipment investment and high cost. Secondly, in the process of removing solid impurities, sewage is usually used After flowing through the filter screen, the solid impurities in the sewage remain on the filter screen. The workers remove the impurities on the filter screen at regular intervals, wh...
