The overall energy consumption of the aerobic compact sludge system is low, and the effluent quality can reach even better than that of the traditional activated sludge process. The sludge is cultivated under the aerobic condition, and the layered structure of the compact sludge forms aerobic, anoxic and anaerobic areas, and the structural characteristics of the compact sludge can realize the denitrification and dephosphorization effects to a certain extent.

It is therefore desirable to provide an activated sludge biochemical reactor to solve the above-mentioned technical problems.
