复合微生物菌剂对高温堆肥进程及有害气体排放的影响

研究了复合微生物菌剂用于高温堆肥对堆肥进程及期间有害气体排放量的影响. 以牛粪与稻壳为原料，分别设置接种复合微生物菌剂的处理组和空白对照组，对比了堆肥中各物理、化学和生物学指标及有害气体(甲烷和N2O)排放量. 结果表明，接种复合微生物菌剂可以加快堆体升温，延长堆体高温持续时间，缩短堆肥腐熟时间，减少有害气体(甲烷和N2O)的排放.

Effects of compound microbial agents on high-temperature composting process and harmful gas emissions

High-temperature composting is a common way to treat agricultural solid waste, but its composting process is slow. A large amount of harmful gases pollute the environment during the process. The impact of compound microbial agents applied to high-temperature compost on the process of composting and harmful gas emissions during the period were studied. In this experiment, cattle manure and rice husk were used as raw materials to set up a treatment group inoculated with a composite microbial agent and a control blank group, and to compare the physical, chemical, and biological parameters of the compost, and the emission of harmful gases (methane, N2O). It can be seen that the inoculation of the compound microbial agent can accelerate the temperature rise of the reactor body, prolong the duration of the high temperature of the reactor body, shorten the composting time, and reduce the emission of harmful gases (methane, N2O).
