The invention provides cleaning devices used for cleaning filtering membrane racks in a sewage treatment tank. The cleaning devices comprise vibration units arranged in clear water channels and used for generating vibration, gas guide pipes with one ends arranged in the clear water channels and positioned at the vibration units, and gas generation devices connected with the other ends of the gas guide pipes. According to the cleaning devices, when a sewage treatment system is in an intermittent state, filtering membranes formed by dirt will attach to the filtering membrane racks and block the gaps among vibration pieces; the cleaning devices are started; gas enters the clear water channels through the gas guide pipes, and the vibration units generate vibration waves; the vibration waves beat the bubbles in the clear water channels into small bubbles; under the effect of the vibration waves, the small bubbles are diffused from the gaps between adjacent vibration pieces to the outer surfaces of the filtering membrane racks, such that the filtering membranes attached to the filtering membrane racks are stripped. Therefore, the purpose of cleaning the filtering membrane racks is achieved.
Description
technical field [0001] The invention relates to the technical field of water treatment, in particular to a cleaning device. Background technique [0002] At present, in the existing sewage treatment equipment, the sewage filter device is commonly used as a sand filter, the volume of the sand filter is relatively large, and the filter element of the filter is easy to block and harden, resulting in poor filtering effect, and after hardening A large amount of clean water needs to be used for backwashing, and the sewage generated by backwashing needs to be filtered again, resulting in low sewage treatment efficiency of sewage treatment equipment. Contents of the invention [0003] In order to solve at least one of the above-mentioned technical problems, the object of the present invention is to provide a cleaning device capable of effectively cleaning the filter membrane holder, [0004] In view of this, the present invention provides a cleaning device, which is used for clea...
