摘要
从能量和熵的角度,系统阐明了在达到相同收集效果时生活垃圾源头分类收集比混合后再分选收集所需输入的能量要少,并提出将我国生活垃圾分为快熵变速度的活性生活垃圾和慢熵变速度的惰性生活垃圾两类。新鲜果蔬、厨余垃圾等化学性质活泼的活性垃圾组分采用"源头分类投放-收集-运输"的收运方式,纸张树叶纤维类、橡塑玻璃金属类、药品电子废物等惰性垃圾组分采用"源头混合收集-运输-再分选"的收运方式。将2种收运方式有机结合在一起的生活垃圾分类收集模式既具有节约能源、操作方便,又具有方便居民实际操作等优点。
According to energy and entropy analysis, the result that the input of energy in the municipal solid waste(MSW)source-classified collection process is less than that in MSW mixing collection process for the same effect, is calculated and proved. Furthermore, a model for MSW classified collection in China is advanced that active waste with fast entropy change and the other inert waste with slow entropy change should be sorted as two parts of MSW. Active waste such as fresh fruit and vegetable, kitchen waste would be source-classified collected by residents and then transported, while the other inert waste including paper, leaves, textile, rubber, plastics, glass, metal, medicine and electrical waste could be source-mixed collected by residents and afterwards further classified. The newly MSW classified collection model synthetically combines MSW source-classified collection with MSW source-mixed and further-classified collection, would save energy, contribute to convenient operation, and moreover make MSW classified collection convenient for residents at home.
