AI Technical Summary

Technical Problem

In existing technologies, the separation effect of inorganic mud and sand and organic matter attached to their surface is not good, which affects the organic matter removal efficiency. Furthermore, increasing the stirring speed will increase the turbulence of the influent, resulting in insufficient mixing of sewage and return sludge.

Method used

A circulating fluidized bed reactor is adopted, which drives the sliding of the circulating pipe and the rotation of the stirring shaft through the lifting component. Combined with the adjustment of the tilt angle of the stirring blades, the liquid circulation and rapid separation of organic matter on inorganic mud and sand are realized.

Benefits of technology

It improves the separation efficiency of inorganic mud and sand with organic matter, enhances the removal effect of organic matter, and avoids the impact of increased liquid flow rate on the suction flow rate of the inlet pipe, thus improving the treatment efficiency.
