Problems solved by technology

This membrane module makes one end of the membrane filaments relatively free, but because the main crossbar of the portal frame is rigidly fixed, the degree of freedom at the top of the membrane filaments is reduced, which affects the flushing effect of the bottom aeration on the top of the membrane filaments

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a hollow fiber curtain membrane module with anti-silting and high aeration efficiency. Background technique [0002] In the known technology, hollow fiber membranes or capillary membranes usually constitute pressure type or submerged membrane filters. Among them, submerged membrane filters are usually used to filter liquids with high impurities. The submerged membrane filter generally reduces the deposition of solid impurities in the liquid on the surface of the membrane and the pollution of the membrane surface by cascading gas from the bottom to the top of the liquid around the membrane. A special application of the submerged membrane filter is to filter the biochemical reaction liquid in the biochemical reactor in the process of sewage treatment. This combination of a biochemical reactor and a membrane filter is called a membrane bioreactor (MBR). Submerged membran...
