Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a fixing device of a porous fiber membrane for sewage treatment. Background Art

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. Existing water treatment and filtration devices often increase the filtration capacity by increasing the membrane bundle area, but the more uniform the water flow in the shell, the more fully the membrane area can be utilized; especially when workers assemble, they often squeeze the membrane bundle to allow the membrane bundle to be installed into the shell, which will cause changes in the distance between the membrane bundles, reduce the uniformity of the water flow and the gas-liquid transfer efficiency, and easily cause the membrane fibers to be blocked.

[0003] For example, the publication No. 2012101283047 discloses a water treatment system and a water treatment method, in which multiple layers of brackets are arranged on the central tube to ensure the fixation and verticality of the central tube. However, the multiple brackets increase the cost and make the installation and removal work cumbersome and complicated.

[0004] Moreover, after the membrane filaments are clogged, it is troublesome to clean the porous structure fiber membrane. The porous structure fiber membrane needs to be removed from the sewage pipe before cleaning, which is not conducive to the cleaning and replacement of the porous structure fiber membrane, thereby increasing the loss.
