Description

Technical Field

[0001] This utility model relates to the field of environmental wastewater filtration technology, specifically to an environmental wastewater filtration device. Background Technology

[0002] To reduce the adverse environmental impact of wastewater discharge, it is necessary to operate wastewater filtration devices to filter the wastewater and discharge the filtered and purified wastewater, thereby reducing the harmful substances in the discharged wastewater and thus helping to achieve the goal of environmental protection.

[0003] China has disclosed an anti-clogging sewage filtration device for environmental protection, with the announcement number CN221713757U. Addressing the problems of screen clogging and incomplete cleaning of internal impurities in existing sewage filtration equipment, this device is designed as a sewage filtration mechanism composed of several inner and outer enclosed screening cylinders. The device is installed at a sewage outlet with a certain height difference, utilizing the potential energy of the falling water flow to drive the rotation of the central rotating cylinder within the transmission mechanism. Several screening cylinders contain screens with varying filtration radii.

[0004] Based on the above-disclosed solutions and existing technologies, in the prior art, when filtering environmental wastewater, impurities in the environmental wastewater are filtered out. The filtered impurities remain in the filter screen, and then the filter cartridge is cleaned. However, organic matter in the environmental wastewater may be adsorbed or aggregated on the surface of the filter cartridge, forming a sticky film, which may accelerate mineral deposition and clog the filter pores, affecting the filtration efficiency. Therefore, we propose an environmental wastewater filtration device to solve the above problems. Utility Model Content
