城市生活垃圾三元二级分类体系的构建及应用前景

Construction and application of the city garbage classification system of three elements and two levels

城市生活垃圾的精细分类是高效高值化垃圾处理的基础和前提,城市生活垃圾处理的关键在于阻遏垃圾混合和如何充分利用湿垃圾。城市生活垃圾三元二级分类体系,即首先将垃圾分为3种类型:干垃圾、湿垃圾和特种垃圾;然后再分别进行二次单一化精细分类。源头分类阻遏了垃圾进入混合状态;对有机垃圾则通过物理破碎、微生物混合发酵预处理、环境昆虫过腹转化的"三位一体处理技术系统"实现资源化利用。城市生活垃圾三元二级分类体系是一个简化垃圾分类体系,改变了"可回收"与"不可回收"垃圾难以快捷界定的难题。

Fine sorting is the basis and premise of efficient and high-value garbage disposal.The key of MSW disposal is to prevent mixture of garbage and make use of wet garbage. According to the three elements and two levels sorting system, garbage is sorted to dry, wet and special garbage, and secondary sophisticated sorting will be done. Sorting by source could prevent the mixture of garbage, and make use of organic garbage by physical crush, microorganism fermentation insect transformation, so as to establish a trinity disposal technology system and realize resource utilization. The system is a simplified garbage sorting system, which could solve the sorting problem of recyclable and unrecyclable garbage.
