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).
