At present, the domestic kitchen waste treatment adopts the process route based on anaerobic fermentation. This paper introduced the development process of anaerobic fermentation treatment process of kitchen waste, analyzed the influencing factors of anaerobic fermentation treatment process, such as solid content, temperature, tank form, material transportation, material stirring, tank top scum crust and tank bottom sand, etc., discussed the adaptability of dry anaerobic fermentation and wet anaerobic fermentation, and pointed out that many factors need to be considered when choosing dry anaerobic fermentation or wet anaerobic fermentation process, such as local garbage classification, kitchen waste composition,pretreatment process, etc.
