乡镇垃圾综合利用途径分析研究

摘要

社会主义新农村建设推动了乡镇经济的发展，但乡镇的环境问题并没有随之解决，而固体废弃物的综合利用成为解决当前乡镇环境问题的有效手段之一。乡镇垃圾现状分析表明，其组分以有机易腐成分为主，不适用于城市垃圾的处理方式。乡镇垃圾经合理分类，其综合利用的主要途径有三条，包括可回收垃圾-回收-循环再利用，有机垃圾制肥-肥料-回田，餐厨垃圾、人畜粪便、秸秆等有机垃圾厌氧发酵-沼气-热能或电能。该途径可最终实现乡镇垃圾的资源化和能源化。%The construction of new rural areas is promoting the development of economy in villages .But environmental prob-lem in rural areas is becoming more serious.Comprehensive utilization of solid waste becomes one of the effective means to solve the environmental problems.Rural wastes mainly consists of putrid components, which need different treatment methods as com-pared with urban wastes.There are three approaches for waste utilization:recycle garbage-reclaim-recycle; organic refuse -compost-organic fertilizer; organic waste-anaerobic digestion -methane-heat/electricity.These approaches can achieve re-source recovery and energy recovery of rural wastes.
