Due to the presence of aerobic, facultative aerobic and anaerobic microorganisms in aerobic granules, they are suitable for the treatment of refractory organics in the industrial wastewater. The slowly biodegradable organics hydrolysis process is slow and result in a high energy consumption. In this project, based on the understanding of the hydrolysis mechanisms of the slowly biodegradable organism under aerobic, anoxic and anaerobic conditions, an adsorption-hydrolysis-degradation integrated processes using aerobic granules have been proposed. The hydrolysis process of slow biodegradable organics in automobile painting wastewater and the degradation of fast biodegradable organics is separated efficiently using the huge adsorption ability of aerobic granlues. The effluent from the hydrolysis unit is utilized in the degradation unit to reduce the retention time and energy demand. The main research contents include: (1) Cultivation and acclimation of aerobic granule sludge for automobile painting wastewater treatment; (2) Evaluation of adsorption properties of aerobic granule sludge for organics in automobile painting wastewater; (3) Hydrolysis mechanisms and products of the slow biodegradable organics; (4) Evolution of the microbial communities and their relationship with the reactor performance; (5) Simulation the hydrolysis and biodegradation processes of slow degradation organics in the aerobic granule sludge system. The results will provide a new, efficient and energy-saving choice for automobile painting wastewater treatment.
