堆肥化技术应用于生活垃圾预处理方案的费用-效益分析

Cost - benefit Analysis on Composting of MSW Pretreatment Project

在有关实验分析的基础上,从工程应用角度探讨垃圾综合处理中采用堆肥化技术作为预处理的可行性。采用费用-效益分析方法,通过对3组有无堆肥预处理工艺的垃圾处理方案的比较,以定量和定性的指标综合评价各组方案的技术经济效果。结果表明,根据我国城市垃圾成分特点,在卫生填埋和焚烧或综合处理中增加堆肥化技术作为预处理在工程上是可行的,经济指标优于传统垃圾处理方案。

Based on experiment analysis the feasibility of compost applied to pre - treatment of MSW was probed from the engineering application point of. The three group projects of MSW treatment with or without composting pre - treatment process were compared by means of cost - benefit analysis method. The techno - economy effect of each group was evaluated quantifica-tionally and qualitively. The results show that composting pre - treatment combined with incineration, sanitary or comprehensive treatment was feasible in engineering according to the component characteristics of MSW in our country. Its economic indexes were better than those of tratditional MSW treatment project without composting pre - treatment.
