Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically a wastewater treatment residue filtration device. Background Technology

[0002] Wastewater treatment utilizes physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, fully utilizing water resources. Physical methods separate and recover insoluble suspended pollutants (including oil films and droplets) from wastewater through physical processes. These methods include gravity separation, centrifugation, and filtration. Chemical methods include neutralization, oxidation-reduction, and adsorption. Neutralization adjusts the pH of wastewater to a neutral range to minimize its impact on subsequent treatment steps or directly meet discharge requirements. Oxidation-reduction can convert toxic and harmful substances into harmless or easily treatable forms. Adsorption utilizes materials such as activated carbon and zeolite to adsorb organic pollutants and certain heavy metal ions from wastewater. Biological methods utilize the metabolic activity of microorganisms to transform organic pollutants in solution, colloidal, and finely suspended states into stable and harmless substances.

[0003] Existing wastewater treatment residue filtration devices still have certain drawbacks in use. During long-term use, the internal filter holes of traditional residue filtration devices are easily clogged, resulting in poor wastewater flow and further preventing the effective filtration of residues in the wastewater, thus reducing the filtration efficiency.
