Description

Technical Field

[0002] One of the core links of sewage treatment technology is solid-liquid separation. Solid-liquid separation technology aims to effectively separate solid impurities such as suspended solids, sediments, grease, fiber, etc. in sewage from liquid to improve water quality and meet environmental protection requirements. There are already a variety of solid-liquid separation mechanisms on the market. They use different principles and methods, such as gravity sedimentation, centrifugal separation, membrane filtration, etc. to achieve solid-liquid separation in sewage. These technologies often face some challenges in practical applications. One of the most prominent problems is the cleaning of solid impurities after solid-liquid separation.

[0003] Specifically, after the existing solid-liquid separation mechanism completes the solid-liquid separation, solid impurities often accumulate in specific parts of the mechanism, such as the bottom of the sedimentation tank or the inner wall of the centrifuge. These solid impurities not only occupy space and affect the normal operation of the mechanism, but may also produce odor and breed bacteria due to long-term retention, and even cause secondary pollution. Therefore, we need to propose a solid-liquid separation mechanism for sewage treatment. Utility Model Content
