危险废物资源化技术四维综合评价:以废有机溶剂及含重金属废物为例
Four-dimensional comprehensive evaluation of hazardous waste resource utilization technologies:A case study on waste organic solvent and heavy metal contained waste
摘要
Abstract
Existing technologies for the resource utilization of hazardous waste,suffer from inefficiency,significant environmental impacts,poor economic benefits,and adverse social effects in China.There is also a lack of systematic analysis and comprehensive evaluation of these problems.Therefore,this study took the resource utilization technologies of waste organic solvents and heavy metal contained waste as examples.From the perspectives of resources,environment,economy,and society,a comprehensive evaluation system for hazardous waste resource utilization technologies was constructed,consisting of seven criteria layers and twenty indicators.The improved entropy weight method was used to determine the weights,and the TOPSIS method was employed to quantitatively evaluate eight cases of these two types of hazardous waste.The study found that for waste organic solvents,vacuum distillation had significant advantages in terms of product net profit(5.906％)and product quality(5.528％),resulting in a higher comprehensive score index(0.687)compared to extraction distillation(0.481)and atmospheric distillation(0.422).As for heavy metal contained waste,the combined process of pyrometallurgical smelting and wet refining(0.784)was identified as the optimal process.It not only addressed the low resource utilization rate(8.404％)in pyrometallurgical smelting processes(0.458,0.450),but also avoided the extensive addition of auxiliary materials and subsequent complex purification processes in wet refining processes(0.486,0.645).This approach maximized economic benefits(with an overall weight of 32.053％in the economic layer).The results of this study can provide scientific support and reference suggestions for optimizing hazardous waste resource utilization technologies in the field of waste treatment applications.关键词
