Optimization method of village and town household garbage collection and transportation treatment system

Abstract

The invention discloses an optimization method of a village and town household garbage collection and transportation treatment system. The optimization method comprises the following steps: (1) classifying villages and towns: dividing the villages and towns in China into three types of villages and towns, including surrounding villages and towns, intensive villages and towns and village/farmer aggregation villages and towns; (2) determining a garbage collection and transportation treatment mode: proposing garbage collection and transportation treatment mode schemes suitable for three types ofvillages and towns in combination with main garbage treatment modes in rural areas in China at present; (3) constructing an evaluation model: constructing a hierarchical structure model of an evaluation index system according to household garbage collection and transportation treatment modes possibly adopted by various types of villages and towns in the future; and (4) evaluating the practicability: comprehensively comparing the schemes from four dimensions of technicality, economy, sociality and environment by utilizing a group decision hierarchy analysis method, and determining the practicability priority of each scheme. According to the method, the garbage collection and transportation treatment efficiency is effectively improved, and the method has important significance in reducing the domestic garbage treatment cost, improving the garbage management level and improving rural ecological environment pollution.

Description

technical field [0001] The invention relates to an optimization method for a collection, transportation and treatment system of domestic garbage in villages and towns. Background technique [0002] The harmless treatment of domestic waste involves energy recovery and environmental protection. [0003] In villages and towns, with the changes in life and production methods, the traditional recycling method of raising livestock with kitchen waste and using livestock manure as fertilizer no longer exists. Therefore, the centralized treatment of domestic waste in villages and towns has become a problem that needs to be solved at present. [0004] However, a practical problem is that the terrain conditions in rural areas are complex, the population distribution is uneven, the area varies greatly, and the rural households live relatively scattered, resulting in uneven distribution of rural domestic garbage, low density and wide distribution of garbage collection, resulting in garb...

Problems solved by technology

[0004] However, a practical problem is that the terrain conditions in rural areas are complex, the population distribution is uneven, the area varies greatly, and the rural households live relatively scattered, resulting in uneven distribution of rural domestic garbage, low density and wide distribution of garbage collection, resulting in garbage collection. Difficult transportation, high cost, difficult to establish a sound garbage collection and transportation system

[0005] At present, some domestic scholars use AHP, fuzzy comprehensive evaluation and mathematical model calculation of gray relational method to evaluate and optimize rural domestic waste disposal schemes. In the collection and transportation system, the waste collection and transportation system costs more than half of the total cost
