AI Technical Summary

Technical Problem

In existing anaerobic wastewater treatment, anaerobic reactors have slow start-up, low mass transfer efficiency, and are prone to sludge loss. Furthermore, sludge granulation takes a long time, is difficult, and is costly.

Method used

An anaerobic reactor with automatic sludge washing is used. By adding pre-granulated seed sludge and modifying the reactor structure, a density difference dynamic is formed by using a gas guiding device to achieve sludge-water separation and self-circulation, and to rapidly cultivate anaerobic granular sludge.

Benefits of technology

It shortened the start-up time of the anaerobic reactor, improved the mass transfer efficiency, and enabled the rapid granulation of sludge, ensuring the stable operation of the reactor.
