AI Technical Summary

Technical Problem

Existing aeration tanks are inefficient and prone to overflow when the wastewater volume is too large, causing work interruptions and making it impossible to treat wastewater efficiently.

Method used

An aerated biological filter was designed, comprising an aeration backwash tank, a water distribution tank, a backwash component, and an aeration component. The design of the inlet channel and the distribution channel prevents sewage overflow, and an overflow pipe and an overflow tank are installed on one side of the water distribution tank to improve the aeration backwash efficiency.

Benefits of technology

It effectively prevents sewage overflow, improves aeration and backwashing efficiency, ensures the continuity and efficiency of sewage treatment, and reduces the possibility of work interruption.
