AI Technical Summary

Technical Problem

Existing technologies in solid-bed ceramic membrane bioreactors for high-pressure gas dispersion of sodium manganese ore suffer from membrane fouling problems, high aeration energy consumption, difficulty in effectively removing manganese ions, and the existing devices cannot meet drinking water hygiene standards.

Method used

A solid-bed ceramic membrane bioreactor using high-pressure gas dispersion of sodium manganese ore is employed. High-pressure gas is used to flush the ceramic particles and sodium manganese ore particles. By combining specific ceramic particle size and material, the aeration pressure is reduced, the membrane service life is extended, and automatic aeration is performed by monitoring the transmembrane pressure difference through a computer, thereby improving the manganese removal efficiency.

Benefits of technology

It achieves efficient manganese removal, reduces membrane fouling, extends membrane life, reduces aeration energy consumption, and the effluent quality meets national drinking water standards.
