The invention relates to the field of waste water treatment, in particular to a production waste water treatment equipment for polyaluminum chloride and a waste water treatment process thereof. Including cleaning equipment, sedimentation tank, filter device. The cleaning equipment and the sedimentation tank are connected by a conveying device. The sedimentation tank is connected by a conveying device and a filtering device. The filter press plate is installed on the base. The track motor can be front mounted on the base through the slide rail. The base is provided with a first tooth groove meshing with the pinion. The bull gear is fixedly installed on the output shaft of the track motor. The filter plate gear meshes with the bull gear. The support arm rotates around the output shaft of the orbital motor. The support arm is configured such that when the filter plate gear is at the highest position, the continuous movement of the unloading device to the left causes the filter press plate to tilt to the right. And when the filter plate gear descends, it contacts with the arc-shaped contact surface, so that the filter press plate keeps tilting to the right. In this way, the filter residues on both sides of the filter plate can be cleaned and dumped, the efficiency of dumping filter residues can be improved, and the wear of the tracks can be reduced.
Description
technical field [0001] The invention relates to the field of waste water treatment, in particular to a production waste water treatment equipment for polyaluminum chloride and a waste water treatment process thereof. Background technique [0002] In the process of preparing polyaluminum chloride, it is necessary to wash the bauxite before further treatment. After washing the bauxite, a large amount of waste water will be produced. There are a large amount of bauxite impurities in the waste water, such as The damage to the environment will be caused if the wastewater is not treated, so it is necessary to filter the wastewater. [0003] In the existing filter device, after the filtration is completed, each filter press plate slides on the track, so that the distance between the densely distributed filter press plates gradually increases, and the filter residue is separated from the filter press plates. During this process, the filter press plates are all in a vertical state, ...
