Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater purification device for environmental protection. Background Technology

[0002] With increasing environmental awareness, wastewater treatment has become a crucial aspect of urban construction and industrial development. Wastewater treatment devices for environmental protection, serving as critical infrastructure, are widely used in the treatment of domestic sewage and industrial wastewater. These devices employ physical, chemical, and biological methods to purify wastewater through multiple stages, aiming to reduce pollutant levels and improve water quality to meet discharge standards or reuse requirements. The development of such devices is of great significance for water resource recycling and ecological environmental protection.

[0003] In existing technologies, common wastewater purification devices typically include structures such as purification tanks, sedimentation tanks, water pumps, and filter components. Their technical principle mainly relies on the decomposition of organic pollutants by microorganisms attached to biological packing materials, combined with sedimentation and filtration to achieve solid-liquid separation. For example, some devices use a fixed-installation layer of biological packing materials, which provides oxygen through an aeration system to promote microbial metabolism. At the same time, gravity sedimentation and mesh filters are used to further remove suspended solids, while water pumps are used to transport wastewater and purified water to ensure the continuity of the process.

[0004] However, existing technologies suffer from cumbersome biological packing replacement operations. Since biological packing is usually fixedly installed inside the purification chamber and has a complex connection structure, replacement requires stopping the machine and disassembling multiple parts, which is not only time-consuming and labor-intensive, but also affects the continuity and stability of the purification process and increases maintenance costs.
