  • 摘要: 为明确我国餐厨垃圾不同处理模式下碳排放情况，以中国南方某城市为研究对象，结合实地调研数据，对比研究了集中式好氧堆肥、集中式厌氧发酵和分散式好氧堆肥3种处理模式下的碳排放量。结果表明，集中式好氧堆肥的碳排放总量最高，而集中式厌氧发酵碳排放总量最低。此外，分散式好氧堆肥的主要优势在于可减少收集运输过程的碳排放且可避免其他温室气体的无组织排放；在先进节能手段和控制电耗的措施下，相比于集中式好氧堆肥模式，分散式模式可实现760.91 kg的碳减排(以CO2计)。然而，餐厨垃圾厌氧发酵模式因其可实现有机质产沼气，总碳减排空间是好氧堆肥的22倍,是一种绿色、低碳的餐厨垃圾处理方式，对实现餐厨垃圾资源化、无害化和减量化具有现实意义。
    Abstract: In order to illustrate carbon emissions from food waste disposal, a city of southern China was taken as a research objective. In combination with its field survey data, the carbon emission amounts from three typical food waste disposal modes, such as centralized aerobic composting, centralized anaerobic digestion, and decentralized aerobic composting, were compared and studied. Results show that the total carbon emission of the centralized composting was the highest, while the centralized anaerobic was the lowest among three modes. Decentralized disposal mode reduced the unorganized and transportation carbon emission. Under the measures of advanced energy saving and power consumption control, it could realize 760.91 kg (calculated as CO2) carbon emission reduction compared with centralized aerobic composting mode. The biogas production in anaerobic digestion alleviated the carbon emission from food waste. Ideally, its carbon emission reduction space could reach 22 times that of aerobic composting, which rendered anaerobic digestion a green and low-carbon disposal option for the practices of resources, harmlessness and reduction of food waste.
