Introduction: Anaerobic digestion of sludge means that under anaerobic conditions, facultative bacteria and anaerobic bacteria will decompose biodegradable organic matter in the sludge into carbon dioxide, methane and water, etc. Process is one of the common methods for sludge reduction and stabilization.

Effect of sludge anaerobic treatment:

1) Reduce the sludge volume; 2) Stabilize the sludge properties and reduce the amount of decomposable and perishable substances in the sludge; 3) Improve the dehydration effect of the sludge; 4) Generate usable methane gas with good economic benefits; 5 ) Eliminate malodor; 6) Improve the sanitary quality of sludge.

There are problems with sludge anaerobic digestion: most of the domestic sludge anaerobic treatment projects have egg-shaped concrete structures, which have poor operating results. In summary, there are the following problems: 1) the fermentation temperature cannot be guaranteed; 2) the bottom sediment after long-term operation; 3) the material is layered and cannot be fully mixed; 4) the top scum foam cap is blocked; There is still odor; 6) Gas production efficiency is low.
