[0002] Wastewater treatment refers to the process of purifying wastewater to ensure that it meets the water quality requirements for discharge into a certain water body or reuse. Activated carbon filter is a commonly used water treatment equipment. As a pre-treatment for water treatment and desalination systems, it can adsorb residual chlorine that cannot be removed in the previous stage filtration, effectively ensuring the service life of the subsequent equipment, improving the water quality, and preventing pollution, especially free residual chlorine poisoning from ion exchange resins, etc. At the same time, it also adsorbs pollutants such as small molecular organic matter leaked from the previous stage, and has a more obvious adsorption and removal effect on odor, colloids, pigments, heavy metal ions, etc. in water.

[0003] The existing activated carbon filter is a single filtration method and cannot achieve multiple internal circulation filtration, so the filtration effect is not particularly ideal. After long-term use, the filter screen on the surface of the activated carbon filter element will become clogged, affecting the flow of water into the filter element and contact with the activated carbon. It requires manual disassembly of the machine to clean, which is more troublesome. Therefore, an activated carbon filter for sewage treatment is proposed to address the above problems.
