title: [Research advances in anaerobic co-digestion of biogas fermentation substrates].
abstract: With global climate change, more and more attention has been paid to the development of bio-energy. Biogas fermentation, as a fairly mature technology of bio-matter energy transformation, has received considerable attention and experienced much development. How to improve the efficiency of biogas fermentation and promote its industrialization is a pressing issue. Anaerobic co-digestion is a simple, low-cost, and high-efficiency method for enhancing the efficiency of biogas fermentation, and received increasing attention from related researchers. This paper summarized the characteristics of various fermentation substrates, reviewed the research advances in the co-digestion of animal manure, sewage sludge, and industrial waste, with the focus on the advantages of co-digestion and the factors affecting the rate and efficiency of co-digestion, and prospected the future research of co-digestion and its application, aimed to provide theoretical guidance for the promotion and application of co-digestion techniques.
