Edible fungal residues and Baijiu's waste spent grains were used as raw materials for co-composting, the nitrogen changes during the composting process and their maturation process were studied. Fungal residues and spent grains were mixed in a self-made compost reactor with a mass ratio of 1∶4 and fermented for 26 days, based on previous experiments. The results showed that, ammonia nitrogen content decreased by 23.21%, nitrate nitrogen content increased by 121.08%, while organic nitrogen and total nitrogen content increased by 24.56% and 34.38%, respectively. Furthermore, full maturity of the compost was achieved according to the following indexes: temperature, chroma, pH, conductivity, degradation rate of organic matter, ammonia nitrogen, nitrate nitrogen, T value, water-soluble organic carbon and its ratio to organic nitrogen. Therefore, it can be concluded that the co-composting is of practical value to the resource utilization and disposal of Baijiu's waste spent grains and edible fungus residues.
