Problems solved by technology
[0002] There are many kinds of existing sewage treatment methods, but none of them is perfect. For example, the commonly used MBR membrane biological reaction treatment method has the advantages of large biomass, high treatment efficiency, and less residual sludge. But at the same time, it is easy to form membrane fouling. Suspended pollutants in the mixed liquid, dissolved organic matter, and microbial deposition on the surface of the membrane, as well as fibers and debris in the activated sludge, will reduce the permeability of the membrane to varying degrees. ; Furthermore, the membrane needs to be cleaned or replaced frequently, and the operation and maintenance cost is relatively high, which is unfavorable for popularization and application. For this reason, the present invention provides a composite filter module sewage treatment equipment for solving the above problems

One embodiment of the present invention discloses a composite filter assembly. The composite filtering assembly comprises: a frame; a plurality of hollow fiber membrane groups used for filtering sewage and located within the frame; and an electrolysis assembly mounted on the frame and used for electrolyzing the sewage in the frame. A sewage treatment device comprises the composite filtration assembly. The composite filter assembly utilizes the electrolysis assembly to generate an electric field in order to make anions and cations directionally move and avoid the anions and cations from depositing on the hollow fiber membrane groups, bubbles generated by electrolysis facilitate the removal of sludge attached to the hollow fiber membrane groups, and the presence of the electric field is in favor of improving the cleaning effect of the hollow fiber membrane groups, so the cost and the difficulty of operation and maintenance are reduced.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to sewage treatment equipment with a composite filter assembly. Background technique [0002] There are many kinds of existing sewage treatment methods, but none of them is perfect. For example, the commonly used MBR membrane biological reaction treatment method has the advantages of large biomass, high treatment efficiency, and less residual sludge. But at the same time, it is easy to form membrane fouling. Suspended pollutants in the mixed liquid, dissolved organic matter, and microbial deposition on the surface of the membrane, as well as fibers and debris in the activated sludge, will reduce the permeability of the membrane to varying degrees. ; Furthermore, the membrane needs to be cleaned or replaced frequently, and the operation and maintenance costs are relatively high, which is not conducive to popularization and application. For this reason, the present invention ...
