用生命周期评价北京市城市垃圾处理工艺

RESEARCH ON LIFE CYCLE ASSESSMENT TO THE DISPOSAL TECHNICS OF BEIJING CITY MUNICIPAL SOLID WASTE

根据生命周期评价(LCA)的原则 ,对北京市城市垃圾的不同处理方式进行了较为系统的LCA评价。结果表明,卫生填埋处理、焚烧处理、综合处理的环境影响潜力分别为3.59×10 -2、5.87×10 -2与1.90×10 -2。处理成本分别为97.8元/(人·a)、127.4元/(人·a)和69.0元/(人·a)。综合处理垃圾在环境效益和经济效益方面都优于其它方法。

Based on the LCA Principle,this paper does the systematic research on Life Cycle Asˉsessment of different treatment technics of municipal solid waste at Beijing City.As the results of the experiments illustrated,the environmental influence potential of landfill disposal,incineration disˉposal and synthesized disposal are3.59×10 -2 、5.87×10 -2 and1.90×10 -2 respectively.The costs of the treatments are97.8Yuan/(person,year),127.4Yuan/(person,year)and69.0Yuan/(person,year).The environmental and economic benefits of the synthesized disposal are greater than those of other approaches.
