Study on Operating Principle and Application of an Advanced Integrated Processing Technology - Air Lift Bioreactor (ALB) for Nitrogen and Phosphorus Removal

摘要

ALB integration is consisted of anaerobic hydrolysis regulating, anaerobic aerobic reaction, air-lift reflux circulating and suspension clarifying precipitate. It is a new compact energy-saving technology of active sludge nitrogen and phosphorus removal. Its properties include shorter flow path, less land used, lower construction cost, lower operation cost, less discharge sludge, easier management, more reliable operation and so on. It propitious to be used for small-scale sewage treatments.
