Ultrafiltration membrane sewage treatment equipment based on non-compact filter element

Abstract

The invention discloses ultrafiltration membrane sewage treatment equipment based on non-compact type filter elements, which comprises a plurality of rows of non-compact type filter elements arranged side by side, the outlet ends of the plurality of rows of non-compact type filter elements are respectively communicated with a plurality of water outlet branch pipes, the water outlet branch pipes are communicated with a water outlet main pipe, the water outlet main pipe is communicated with a water outlet joint, and the water outlet joint is communicated with a water inlet pipe. One ends, far away from the outlet ends, of the multiple rows of non-compact filter elements are respectively communicated with a plurality of back-washing branch pipes, the back-washing branch pipes are communicated with a back-washing main pipe, the back-washing main pipe is communicated with a back-washing joint, each non-compact filter element is arranged in an assembly box, and the back-washing joint is arranged in the assembly box. A first cover plate and a second cover plate are respectively arranged at two opposite ends of the assembly box, and are respectively positioned at two axial ends of each non-compact filter element. According to the invention, the filtering effect is improved, the filth blockage frequency of the body is reduced, the service time is prolonged, and meanwhile, the backwashing efficiency and the backwashing effect are improved. The invention is suitable for the technical field of sewage treatment.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an ultrafiltration membrane sewage treatment equipment and a sewage treatment method based on a non-compact filter element. Background technique [0002] At present, in the production and processing, it is unavoidable that sewage will be generated. In order to avoid the pollution of sewage to the environment, sewage needs to be treated to meet the discharge standard, or it can be recycled according to specific needs, thereby avoiding the waste of water resources. The existing filter cores with ultrafiltration membranes are all compact, that is, the multi-layer filter layers constituting the filter core are tightly wound. Since there is no gap between the filter layers, impurities in the sewage can easily block the filter core. At the local position, both the outer filter layer and the inner filter layer at this position are blocked, reducing the filtering eff...

AI Technical Summary

Problems solved by technology

The existing filter elements with ultrafiltration membranes are all compact, that is, the multi-layer filter layers constituting the filter element are tightly wound. Since there is no gap between the filter layers, the impurities in the sewage can easily block the filter element The local position, so that the outer filter layer and the inner filter layer at this position are blocked, reducing the filtering effect

Moreover, the frequency of dirty and clogged compact filter elements is high, and the cleaning ability of backwashing is weak, resulting in poor backwashing effect
