Abstract: The distributed aerobic composting equipment has the advantages of intensive， environmental protection， economy， etc， and has a broad market prospect. The self-developed distributed composting device was used to carry out the continuous compost experiment of vegetable waste collected from the market， and the operation efficiency and the quality of compost products were analyzed in this study. The results showed that the mass loss rate of organic waste was 72.1%， and the moisture content of the products was 51%～55% under the conditions of continuous feeding and composting for more than seven days. The average energy consumption of the device was 220 kWh/d. Thermal insulation heating was the most energy consuming part of composting equipment， which was 160 kWh/d. It was mainly used for heat supplement of the composting bin and water vaporization. According to the energy balance analysis， the existing operating energy consumption could be reduced by 40%， reflected in strengthening insulation， accelerating the water vapor discharge and waste heat recovery in the warehouse and other links. Secondary compost of compost products could further reduce the moisture content， improve the pH， nutrient content and seed germination index， so as to improve the integrated quality of compost products and reduce the cost of vegetable waste. Continuous aerobic compost combined with secondary compost to treat vegetable waste is an important technical way to realize the rapid stabilization， reduction and recycling of vegetable waste.

Key words: vegetable waste, scattered composting device, secondary compost, energy consumption analysis
