Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater purification, in particular to a wastewater purification device which is convenient for replacing a filter element. Background Art

[0002] Domestic wastewater refers to the washing water discharged by residents in their daily lives. In fact, only a small part of the wastewater is treated, and most of it is directly discharged into rivers without treatment, which will cause serious pollution to the environment, especially groundwater resources that are closely related to human survival. Therefore, people often use wastewater purification to purify wastewater before discharging it into the natural environment. Wastewater purification devices are designed to be easy to replace and filter elements due to usage needs, but when in use, there is no aggregation function, and the accumulated waste has no aggregation ability.

[0003] After searching, the Chinese patent document (authorization announcement number CN219942085U) discloses a wastewater purification pool with replaceable filter cartridges, including a main body pool and a water filtering mechanism, wherein a purification mechanism for replacing the filter cartridge is provided on one side of the main body pool. Compared with the existing device, the wastewater purification pool with replaceable filter cartridges can purify water during the pumping and circulation of water through purification modules and grouping covers, which are purification fillers such as activated carbon. By plugging in the filter cartridge and installing the cover, it can be pulled up and down in the main body pool, so that it can be pulled out for replacement and cleaning after a long period of purification work. By fixing the slide rail, multiple groups of purification modules can be pulled out from the plug-in filter cartridge, but when in use, it has no aggregation function and the accumulated waste has no aggregation ability.
