[0002] Activated carbon filter is a commonly used water treatment equipment. Its main filter material is activated carbon. Its function is to effectively remove impurities such as low molecular organic matter, colloidal particles, microorganisms, free chlorine, etc. in water.

[0003] Currently, most common activated carbon filters are composed of an outer shell and an activated carbon filter layer, in which the activated carbon filter layer can basically be disassembled by mechanical energy. However, in the project where the activated carbon filter is used, sewage will pass from one side of the activated carbon filter layer to the other side and be filtered by the activated carbon therein. Since there are more impurities in the sewage just entering the filter, and it is inevitable that there will be slightly larger impurities, some impurities will adhere to the surface of the activated carbon filter layer and block the filter holes, thereby affecting the flow and filtration of sewage. For this reason, we propose a filter with an activated carbon filter structure to solve the above problems. Utility Model Content
