ABSTRACT
WAO and TH are considered as optimal solutions to the sludge problem and have been wildly researched. However, no work has been attempted to compare TH and WAO in research studies and industrial applications in sludge treatment, especially in China. This paper summarized and compared the research studies of TH and WAO in research trends of sludge treatment and industrial factors combined with the actual situation in China. Finally, typical industrial facilities of WAO and TH in China and their conditions are illustrated.
