Abstract

The invention provides filtering membrane cleaning devices and a filtering membrane cleaning method. The filtering membrane cleaning devices are used for cleaning the filtering membranes in a sewage treatment tank. The filtering membranes are positioned in sewage, and are formed by dirt in the sewage. The filtering membrane cleaning devices comprise vibration units arranged on the sewage treatment tank. The vibration units can generate vibration which can be conducted to the sewage in the sewage treatment tank, such that the filtering membranes can be partially stripped under vibration. With the filtering membrane cleaning devices provided by the invention, when a water level is increased to a rated position, the vibration units work to generate vibration, such that the sewage is slightly vibrated; further, the filtering membranes in the sewage are driven to vibrate, such that the dirt on the filtering membranes vibrates and can be partially stripped. Therefore, filtering membrane thickness and compactness are reduced, and can be used for filtering sewage with high efficiency again. Also, sewage input amount and filtering membrane processing amount are kept balanced.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a filter membrane cleaning device and a filter membrane cleaning method. 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 technical problems, an object of the present invention is to provide a filter membrane cleaning device capable of effectively cleaning the filter membrane produced by the filter membrane holder. [0004...
