Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a filter cartridge for sewage treatment. Background Art

[0002] The filter cartridge is an important filtering device, and its main function is to remove solid particles and sediments from sewage. After the sewage is pre-treated by the grid, it enters the primary sedimentation tank, and then enters the filter barrel from the primary sedimentation tank through the connecting pipe. The filter barrel achieves this function through the filter screen. In addition, the filter barrel can also play a mixing role, so that the sewage is evenly distributed, which is conducive to subsequent treatment.

[0003] Most of the existing filter cartridges are directly fed with sewage. When sewage is just fed into the inlet, the filter cartridge will instantly bear a large impact of water flow. Long-term use will easily cause damage to the filter cartridge and reduce the service life of the filter cartridge.
