| Abstract: | As a sewage sludge stabilization technology,autothermal thermophilic aerobic digestion(ATAD) has fast reaction rate,short retention time,high disinfection capacity.ATAD becomes more attractive in sludge treatment of small-scale wastewater treatment plants,and has been widely used in Europe and North America.The microbiological aspect,matter transformation,dewaterability improvement methods and control parameters of ATAD system were well reviewed,and the transformation of the sludge microbial cells,organic carbon,nitrogen and phosphor in the ATAD system was given more attention.The potential novel sewage and sludge treatment processes based on ATAD technology were also introduced. |
