[0001] The utility model relates to the field of sewage treatment, in particular to a sewage filtration and environmental protection purification device. Background Technique

[0002] Sewage treatment refers to the treatment of sewage generated in the fields of industry, agriculture, and life, removing harmful substances therein to achieve the purposes of environmental protection and resource utilization. In the process of sewage treatment, purification is a very crucial step. A more environmentally friendly purification method is the biological treatment method, which uses the biochemical action of microorganisms to degrade organic pollutants in sewage into stable and harmless inorganic substances.

[0003] The sewage collected through the sewer may contain some large particles and suspended substances, and there may also be various organic pollutants in the sewage. If it is discharged into the natural environment without filtration and purification, these organic pollutants will be utilized by microorganisms in nature such as bacteria and algae, resulting in eutrophication of water bodies.
