Description

Technical Field

[0001] This utility model belongs to the field of sewage filter technology, and in particular relates to a multi-stage filtration sewage filter. Background Technology

[0002] Wastewater filters are important devices used for wastewater treatment. Through a combination of physical, chemical, and biological methods, they can efficiently remove impurities, suspended solids, bacteria, and other harmful substances from wastewater, thereby purifying water quality and protecting the environment.

[0003] The accumulation of impurities and suspended solids in wastewater inside filters is a common problem. These deposits gradually clog the filters, severely affecting their normal operating efficiency and requiring frequent cleaning and maintenance. However, many existing wastewater filters are designed with complex disassembly, which greatly increases the difficulty and cost of regular maintenance and cleaning. Furthermore, some wastewater filters have limited filtration accuracy, making it difficult to effectively remove fine particles and dissolved pollutants from wastewater, affecting subsequent use. Utility Model Content

[0004] The purpose of this invention is to address the problem that many existing wastewater filters are complex to disassemble, which greatly increases the difficulty and cost of regular maintenance and cleaning.
