基于干湿分类优化的城市生活垃圾收运处理系统研究

为解决"垃圾围城"困境,在充分考量我国城市生活垃圾特点、居民生活垃圾分类能力以及垃圾处理可行方案的前提下,提出以干湿分类为基础,并对干垃圾进行二次分类的城市生活垃圾分类体系。基于此分类体系,对既有生活垃圾收运处理系统的优化调整进行了探讨,提出优化调整原则。最后,以郑州市为例,给出了城市生活垃圾收运处理系统优化调整的具体方案,并证明了新的城市生活垃圾分类体系,以及对城市生活垃圾收运处理系统的优化调整,在提高垃圾资源化率和减少填埋量方面的有效性。

OPTIMIZATION OF COLLECTION AND TRANSPORTATION MANAGEMENT OF MUNICIPAL SOLID WASTE BASED ON DRY AND WET CLASSIFICATION

In order to solve the garbage problem,we established a garbage sorted collection system based on the dry and wet classification,and the secondary classification of dry waste,in consideration of the traits of the municipal solid waste in China,the garbage classification ability of the residents and the feasible solutions to deal with trash.On the basis of this system,the paper discussed the principles to modify the current transportation and disposal management mode in China.Finally,we took Zhengzhou as the example,and established a concrete optimized system.This case showed that the new garbage sorting collection system and the modification to the transportation and disposal management mode was efficient in improving the recycling rate of municipal solid waste and reducing the amount of landfill.
