菇渣无害化处置发酵菌剂工艺优化Mushroom Residue Harmless Disposal Fermentation Agent Process Optimization

摘要:

为有效提高菇渣废弃物的无害化处置效率,进行了发酵菌剂的引选与无害化处置工艺优化研究,结果表明,菇渣中添加30%比例的牛粪或菇渣中添加10%以上的牛粪及3‰复合菌剂均能大大促进菇渣堆肥升温腐熟发酵过程,缩短物料无害化处置周期,随着处理时间的延长,物料pH表现出先上升后逐步下降的趋势。试验中香菇渣物料的发芽指数在无害化处理5天以后均达到了50%以上的安全范围。研究结论证明通过调节菇渣物料C/N及添加复合菌剂可以显著提高菇渣废弃物的无害化处置效率。

To improve the efficiency of harmless disposal of the mushroom residue, the screening of fermen-tation 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 mu-shroom 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.
