摘要
从环境保护和能源利用的视角,以云南省昆明市为案例,采用能值分析法比较垃圾填埋及沼气发电、垃圾焚烧发电和垃圾堆肥3种处理方式的环境负债率和能值产出率,结果显示:从环境保护的角度讲最适合采用的是垃圾堆肥,最不适合采用的是垃圾焚烧;从能源利用的角度讲,最适合采用的是生活垃圾填埋和沼气发电,最不适合采用的是垃圾堆肥;综合考虑3种生活垃圾处理方式的环境负载率和能值产出率,3种处理方式的优劣顺序依次是垃圾填埋及沼气发电、垃圾焚烧发电、不适合采取垃圾堆肥。
From the perspective of environmental protection and energy utilization, taking Kunming Municipality as an example, the energy synthesis of the three disposal methodologies, that is landfill and biogas power generation, power generation from incineration, composting, have been compared in respect of environmental liability and energy yield. It shows that composting is the best in protecting the environment, while incineration is the poorest. Landfill and biogas power generation yields the most energy, eomposting the least. When both environmental liability and energy yield are taken into consideration, the three disposal methodologies could be ranked, from the best to the poorest, as landfill and biogas power generation, power generation from incineration and composting.
