摘要
随着环保意识的不断增强,合肥市逐渐学习其他城市的管理经验,开始重视对建筑垃圾的综合处理,但相应的建筑垃圾处理企业却甚少,资源化利用率较低。文章以建筑垃圾填埋和综合处理2种处理模式为研究对象,运用生命周期评价法,建立评价模型,结合相关研究现状与合肥市基础数据,从环境效益的角度,利用CMLCA软件对比分析建筑垃圾在填埋与综合处理2种模式下的环境负荷值、生态毒性等指标,从而得出建筑垃圾经过综合处理后的环境效益较好,具有良好的发展前景,以呼吁更多的市民及企业家投身到合肥市建筑垃圾的综合处理中,提高综合利用率,并通过分析得到综合处理过程中制砖阶段对环境的不良影响较大,应提高制砖工艺,降低能耗。
With the continuous enhancement of environmental awareness,Hefei gradually learned from the management experience of other cities and began to pay attention to the comprehensive disposal of construction waste.However,there are very few construction waste disposal enterprises,and the utilization rate of resources is low.This paper takes two disposal modes of construction waste landfill and comprehensive disposal as the research object,uses the life cycle assessment method to establish an evaluation model,combines the relevant research status with the basic data of Hefei city,and uses the CMLCA software to compare and analyze the environmental load value,ecotoxicity and other indicators of construction waste under the two modes of landfill and comprehensive disposal from the perspective of environmental benefits.Therefore,it is concluded that the environmental benefits of construction waste after comprehensive disposal are bigger and it has a good development prospect.More citizens and entrepreneurs are encouraged to participate in the comprehensive disposal of construction waste in Hefei City and to improve the comprehensive utilization rate.Through analysis,it is found that the side effect of the brick manufacture in the comprehensive disposal process on the environment is serious,so it is necessary to improve the brick making process and reduce energy consumption.
