The Research on Harmless Disposal Process Optimization of Waste Mushroom Residue

To improve the efficiency of harmless disposal of the mushroom residue, the screening of fermentation agent and the research on optimization of harmless disposal technology were carried out. The results showed that adding 30% proportion of cow dung to mushroom residue or adding 10% cow dung with 3‰ compound agent can greatly increase the temperature of mushroom residue compost, promote fermentation and shorten the disposal cycle. With the extension of processing, the pH of material rise in the early time and then decline gradually. The germination index of mushroom residue reached more than 50% of the safety range at 5 days after innocent treatment. It proved that adjusting the C/N of mushroom residue and adding compound agent can significantly improve the efficiency of harmless disposal.
