Description

Technical Field

[0001] The utility model relates to the technical field of purification equipment, in particular to sewage treatment and purification equipment for environmental protection projects. Background Art

[0002] Sewage treatment can discharge sewage into a certain water body and react with it through reactants to achieve different degrees of purification of the water source. Among them, stirring equipment is an important link in the sewage treatment process. Through stirring, the flocculant and sewage are fully mixed to improve the sewage treatment efficiency.

[0003] However, the existing sewage treatment and purification equipment for environmental protection projects has some technical bottlenecks when using stirring equipment for stirring. Some equipment combines a feeding piece with a stirring piece, hoping to stir while adding flocculants, but the rotation speed of the feeding piece is generally the same as the rotation speed of the stirring piece. This design has obvious problems: it cannot achieve an effective combination of rapid stirring and uniform feeding. Since the feeding speed is consistent with the stirring speed, the mixing efficiency is poor, and the flocculant and sewage cannot be fully mixed in a short time, thereby affecting the sewage treatment effect. Specifically, when the rotation speed of the feeding piece is the same as the rotation speed of the stirring piece, the stirring equipment cannot quickly form a strong stirring force in the initial stage, resulting in a slow mixing process of the flocculant and sewage. For this reason, we propose a sewage treatment and purification equipment for environmental protection projects. Utility Model Content
