Abstract Pretreatment of excess sludge can effectively decompose sludge solids, release cellular components and a large amount of organic matter, thus improving the anaerobic digestion rate of excess sludge.The pretreated cracking solution contains organic substances that can be used as external carbon sources, such as volatile fatty acids (VFAs), which can also be used to solve the problem that external carbon sources are needed due to insufficient carbon sources in the denitrification stage of the sewage plant.Several pre-treatment methods and the treatment effect of the hydrolysate as an additional carbon source for denitrification were introduced. The research direction of surplus sludge pretreatment was suggested.

Key words： excess sludge pretreatment denitrification carbon source
