Abstract

A pilot-scale submerged membrane bioreactor with treating capacity of 15.6 m³/d was developed on the basis of its structural optimization design according to the principle of air-lift internal-loop reactor. Economical aeration intensity of this installation was 96 m³/(m²·h) according to hydrodynamic investigation. Through critical flux test under the condition of economical aeration intensity, critical flux region of the membrane was 30-35 L/( m²·h) when the sludge concentration was less than 13 g/L. Therefore the operation parameters of continuous motion of the pilot installation was determined and under the condition of sub-critical flux of 30 L/( m²·h stable motion of sewage treatment was realized. Energy consumption analysis indicated that the air-to-water ratio of the pilot reactor was 21:1 and the effective unit energy consumption was 0.42 kW·h/m³.
