The sewage mixer plays a vital role in the sewage treatment system. Their main functions and roles can be summarized as follows:

Mixing and homogenization: The sewage mixer, through the rotation of its stirring blades, fully mixes the sewage in the sewage tank (such as the regulating tank, anaerobic tank, aerobic tank, etc.) and the sludge, microorganisms, pharmaceuticals, etc., to ensure that the components in the sewage are evenly distributed. This homogenization process is essential to improve the effectiveness of the subsequent treatment process, as it ensures that the pollutants in the sewage are uniformly in contact with microorganisms, agents, etc., so that biodegradation or chemical reactions are more efficient.

Promote biological reaction: In the biological treatment stage (such as anaerobic treatment, aerobic treatment, etc.), the sewage mixer not only promotes the full contact of sewage and microorganisms through the stirring effect, but also improves the activity of the microbial community. Agitation helps in the uniform distribution of oxygen (in aerobic treatment), but also in the maintenance of an anaerobic environment (in anaerobic treatment). These are conducive to the growth and metabolic activities of microorganisms, thus accelerating the degradation process of pollutants.

Prevent sludge deposition: In static or low-flow sewage tanks, sludge is easy to deposit on the bottom of the pool, which not only reduces the effective volume, but also may affect the treatment effect. Through continuous mixing, the sewage mixer can effectively prevent the deposition of sludge, maintain the fluidity and activity in the pool, and ensure the stable operation of the treatment system.

Improve treatment efficiency: By promoting the mixing and homogenization of sewage, sewage mixers help accelerate the degradation and transformation process of pollutants, thereby improving the treatment efficiency of the entire sewage treatment system. In addition, it can help regulate the hydraulic conditions of the system and optimize the treatment effect.

Reduce maintenance costs: Although the sewage mixer itself requires a certain cost of operation and maintenance, it can indirectly reduce the maintenance cost of the entire sewage treatment system by improving the treatment efficiency and extending the service life of the system. For example, by preventing sludge deposition and maintaining the stable operation of the system, additional costs arising from equipment failure or sediment removal can be reduced.

To sum up, the sewage mixer is an indispensable part of the sewage treatment system, which plays an important role in improving the treatment efficiency, ensuring the treatment effect and reducing maintenance costs.
