Description

Technical Field

[0001] The utility model relates to the field of filtering devices, in particular to a filter used for liquid purification. Background Art

[0002] Liquid purification filters are devices used to remove impurities and contaminants from liquids. They are usually composed of one or more filter media, such as cellulose filter paper, activated carbon, ceramics or other special materials. When the liquid passes through the filter, impurities are captured by the filter media, making the outflowing liquid purer. Liquid purification filters are also used in the process of sewage treatment.

[0003] The disadvantages are low redox potential gradient values ​​of water before and after treatment, low impurity removal efficiency, especially biological nitrogen and phosphorus compounds, antibiotic and drug residues, hormones, fuel additives, surfactant residues, dyes and pesticides, toxic water produced by electroplating, these impurities pollute urban and industrial wastewater and surface water sources, the use of aquatic plants and activated sludge, denitrification can be carried out at relatively low values ​​of water redox capacity, which is not provided by the prototype device, which leads to a reduction in biomass activity time, resulting in a reduction in filtration cycle time and accelerated decay of activated sludge. After biomass regeneration, the increase in the required amount of activated sludge is a long process. Therefore, effective operation of the plant is only possible when the water is untreated for a long time, so it is necessary to improve the filters for liquid purification. Utility Model Content
