Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater filtration device for environmental protection. Background Technology
[0002] Wastewater filtration equipment removes suspended solids, heavy metals, and organic pollutants from wastewater through physical interception, chemical adsorption, or biodegradation. Its core functions include multi-stage filter cartridges and automated cleaning systems, effectively improving water quality safety, reducing subsequent treatment costs, and applicability to various scenarios such as industrial wastewater and domestic sewage. However, current wastewater filtration equipment still has the following shortcomings:
[0003] For example, patent document CN222647680U discloses a wastewater treatment filtration device. This device uses a filter plate to filter larger impurities in the wastewater and activated carbon to further filter and purify finer impurities. When replacing the activated carbon, the filter plate is simply pulled upwards, moving it away from the filter box. Pulling the handle to the right moves the mounting plate and storage tank, removing the storage tank from the filter box for easy replacement. While this device improves wastewater filtration through the filter plate and activated carbon, it does not pre-treat sludge in the wastewater, which can easily clog the filtration mechanism during the filtration process.
