摘要：

With the improvement of living standard of people and the implementation of garbage classification, the production of food waste in China is gradually increasing, which poses a new challenge to environmental pollution control. Anaerobic digestion is one of the mainstream treatment methods because it can realize the resource utilization of food waste. However, characteristics of food waste may inhibit the anaerobic digestion process. This paper summarizes the characteristics of food waste at home and abroad, and finds that the components of food waste in different regions are quite different. Food waste has the characteristics of high perishable organic matter, high protein, high fat, high salt and high crude fiber, which can easily cause some problems such as acidification, ammonia suppression and long solid retention time. They can be relieved by co-digestion with other substances, addition of additives, removal of inhibitors and selection of appropriate processes. Finally, the mitigation methods of each component of food waste are summarized and the research prospects are proposed, to promote the development of resource utilization of food waste. © 2020, Chemical Industry Press Co., Ltd..
