Research Progress of AOA Process and Its Application in Urban Sewage Treatment Plant
Anaerobic-Oxic-Anoxic(AOA)is a new type of sewage biological nitrogen and phosphorus removal process.Based on a comprehensive summary of existing research results,the design parameters for applying AOA technology to treat urban sewage in cold regions of Northeast China are proposed.Compared to the traditional AAO process,the AOA process has significantly reduced dosing and aeration amounts,and features green,low-carbon,strong resistance to shock loads,and flexible and stable operation.
