Abstract

This invention relates to the field of wastewater treatment technology, specifically to a high-efficiency and environmentally friendly wastewater treatment system, comprising a primary sedimentation tank, a sludge discharge tank, and a secondary sedimentation tank. The invention utilizes the conical bottom of the sedimentation chamber in conjunction with cleaning components to automatically collect sediment. Wastewater flow impacts the drive blades on the guide platform, and through a planetary gear transmission structure, kinetic energy is efficiently converted into the rotational power of the scraper, continuously scraping away sediment and discharging it into the sludge discharge tank. This prevents sludge accumulation and caking, significantly improving the sedimentation efficiency of the primary sedimentation tank. The frustum-shaped guide platform guides the water flow smoothly, reducing water flow impact and further optimizing the sedimentation environment. The entire cleaning component requires no additional power, utilizing the self-driving nature of wastewater flow, greatly reducing energy consumption and manual maintenance costs. Stable operation through mechanical transmission enhances the system's automation level, ensuring the continuity and reliability of the wastewater treatment process, achieving high-efficiency and environmentally friendly wastewater treatment with a purely mechanical structure.
