Description

Technical Field

[0002] The turbulence agitation device in the sewage tank is a key piece of equipment in the sewage treatment system. It is mainly used to stir, mix and agitate the sewage in the sewage tank to prevent the sedimentation of solid impurities in the sewage, while promoting full contact between the sewage and the treatment agents to improve the sewage treatment efficiency.

[0003] In existing devices, when the single central stirring paddle rotates, centrifugal force throws solid particles in the wastewater toward the pool wall, forming a wall adhesion layer. This results in incomplete mixing, and large particles of impurities in the wastewater are easily deposited at the bottom of the pool due to gravity. The mixing force is limited, especially for high-concentration wastewater or viscous impurities, making it difficult to achieve thorough mixing. Furthermore, the fixed paddle angle makes it difficult to adapt to changes in different wastewater flow rates and concentrations. Utility Model Content
