Description

Technical Field

[0001] This utility model relates to the field of water pollution control technology, and in particular to a water pollution control filter. Background Technology

[0002] Water pollution control refers to the reduction or elimination of pollutants in water bodies through various technologies and management measures in order to restore and protect the health of water resources. The goal of water pollution control is to ensure the cleanliness and safety of water quality, protect ecosystems, and support the sustainable development of human society.

[0003] In existing technologies, water pollution treatment requires pretreatment before water is added to a reaction tank with chemical agents to precipitate water-soluble impurities, followed by sedimentation and filtration. However, directly discharging water through the reaction tank into the filter during filtration results in a large impact on the filter screen, causing it to be easily damaged. Furthermore, the filter screen is located inside the filter, making it inconvenient to replace. Excessive impurities are easily affected by water impact and adhere to the surface of the filter screen, affecting the flowability of subsequent wastewater. Utility Model Content

The filter screen is located inside the filter, making it inconvenient to replace. Furthermore, excessive impurities are easily affected by water impact and adhere to the surface of the filter screen, affecting the flow of subsequent wastewater. Therefore, this invention proposes a water pollution treatment filter.
