摘要
采用生命周期评价方法建立了建筑垃圾环境影响评价指标体系,并采用模糊集对分析方法对建筑垃圾再生骨料利用、再生原料利用、基础填料利用和填埋4种方式进行了环境影响评价,同时对4种处理方式环境影响优劣进行了排序。结果表明:建筑垃圾再生骨料利用的环境影响最低,最能体现建筑垃圾的资源价值,为建筑垃圾处理方式环境影响的定量评价提供了适用的方法。
In this paper, the life cycle assessment method was used to establish the evaluation index system of the environmental impact for concrete waste treatment options. The set pair analysis method was used to assess the environmental impact of four concrete waste treatment options,which were aggregate recycling,materials recycling,the base filling and the land filling. Meanwhile, the environmental impact of the four treatment options are sorted. The results indicated that the environmental impact of concrete waste for the recycling aggregate is lower than the other treatment options,which can fully reflect the resource value of concrete waste. The paper also provided a suitable method for the quantitative evaluation of environmental impact of construction waste treatment.
