The invention discloses a device and a method of united adjusting and control of oxygen consumption-humidity-temperature of kitchen residue aerobic compost, belonging to the technical field of organic solid waste disposal. The device is added a temperature and humidity control unit, thus the device can united regulate and control the oxygen consumption, humidity, and temperature. The method is characterized in that: first, a ventilation volume is controlled to guarantee the humidity to reach 50-60 %, and temperature deviation caused by ventilation is modified by a water circulation heating or cooling device, the temperature is adjusted to 70-75 DEG C in the first stage, and the temperature is adjusted to 55-65 DEG C in the second stage. Compared with common composting technique, by using the united adjusting and control technique of oxygen consumption-humidity-temperature, the composting time is reduced by 3-5 day, a compost product enters a high temperature composting stage 3 days earlier, the degradation rate of organic matters is increased by 11 %. The method realizes the quantitative reduction and recycling of the kitchen residues, and increases the practicality and application value of the compost product in agriculture. The compost product also can be used in agriculture, forestry and garden, etc.
