AI Technical Summary

Technical Problem

Existing industrial wastewater mixing and aeration devices are difficult to adapt to wastewater tanks of different depths, resulting in insufficient mixing and aeration, which affects the wastewater treatment effect.

Method used

A device comprising a square frame, a mixing component, and an aeration component was designed. The height is adjusted by a screw driven by a geared motor, and a multi-directional mixing is achieved by a rotary motor driving a stirring rod and stirring blades. Air is introduced into the wastewater using a blower and aeration pipes to achieve height adjustment and thorough mixing and aeration.

Benefits of technology

It enables effective mixing and aeration in sewage tanks of different depths, improving sewage treatment efficiency and enhancing the effect of microbial decomposition of pollutants.
