农村生活垃圾处理工艺设计实例——以河南省登封市为例

Design example of rural household waste treatment process——Taking Dengfeng City,Henan Province as an example

为改善农村生活环境,优化垃圾处理方法,对河南省登封市某垃圾处理场农村生活垃圾的组分及渣土特性进行研究,通过初步分拣、二次分拣、深度分选3个步骤进行垃圾分类,将每一步得到的垃圾回收利用,最终产物细渣土用来制备有机肥。该垃圾处理工艺平均每天处理农村生活垃圾60 t,能有效解决普通乡镇每天40~60 t的生活垃圾处理难题。经资源化处理,平均每天可回收玻璃、衣物、金属、轮胎、胶鞋、木材等,可生产压块燃料、塑料颗粒、塑胶、有机肥等。该垃圾处理工艺将农村生活垃圾合理利用,具有较好的生态效益和经济效益。

In order to improve the rural living environment and optimize waste treatment methods,the composition and soil character⁃istics of rural household waste at a waste treatment site in Dengfeng City,Henan Province were studied,and waste classification was carried out through three steps:preliminary sorting,secondary sorting,and deep sorting.The waste obtained from each step was recy⁃cled,and the final product,fine residue soil,was used to prepare organic fertilizer.This waste treatment process processed an average of 60 tons of rural household waste per day,effectively solving the problem of 40 to 60 tons of daily household waste treatment in ordi⁃nary towns.After resource utilization,glass,clothes,metal,tires,rubber shoes,wood,etc.could be recycled on average every day,and could be used to produce briquette fuel,plastic particles,plastics,organic fertilizers,etc.This waste treatment process utilized rural household waste reasonably,which had good ecological and economic benefits.
