Since the push of the "toilet revolution", toilet sanitation and environment have been greatly improved. The manure diversity composting toilet is a novel toilet for separately collecting and composting manure and urine, and has good application potential. However, in the manure composting process, a large amount of odor and methane are generated due to the action of anaerobic microorganisms, and certain influence is generated on human and natural environment. In addition, methane is the second powerful greenhouse gas in the world, has the potential of 28-36 times of carbon dioxide in greenhouse effect, and contributes to the global greenhouse effect by about 20%. Therefore, methane abatement is considered an important means to mitigate the greenhouse effect and achieve carbon neutralization. The aerobic composting of these materials is usually the method of choice by injecting large amounts of oxygen into the composting system in an aerated manner to allow aerobic composting of the microorganisms.
