京津冀工农城固废跨产业跨区域协同利用解决方案研究

Study on the solution for cross-industry and cross-region coordinated utilization of solid waste in the Beijing-Tianjin-Hebei industrial,agricultural and urban areas

京津冀地区人口密度大,重化工业发达,固废产量大,资源环境问题突出。区域内固体废物处理处置存在统计数据信息口径不一、固废资源利用率低、固废种类多且协同不足等问题,极大阻碍了京津冀协同一体化建设进程的推进。本文依据固废无害化、减量化、资源化的原则与目标,分析了京津冀地区涉及工业、农业、城市等多产业固体废物协同利用的可行性,提出了固废跨产业跨区域协同利用的整体思路和解决方案。分析研究认为,应以京津冀地区固废数据库建立为基础,依托固废大比例协同利用、高附加值产品开发、工业材料化应用、烟气超低排放等工艺技术和装置开发,形成固废协同处置集成示范基地,优化其经济运行指标参数,研究新的商业运行模式,加速产业推进。另外,社会各界还应立足于京津冀一体化的宏观视角,积极制定并推行新的标准规范,形成统筹管理体系,实现京津冀工农城固废跨产业跨区域协同利用,解决京津冀地区多产业、多区域的固废处理处置难题。

The dense population,developed heavy and chemical industries and large output of solid waste in Beijing-Tianjin-Hebei region has posed a serious challenge on resources and environmental protection.In addition,there are some problems in the treatment and disposal of solid waste in the region,such as discrepancy of statistical data from different sources,low utilization rate of solid waste resources,insufficient coordinated utilization among various types of solid waste,which greatly hinder the progress of Beijing-Tianjin-Hebei coordinated and integrated construction.In this paper,based on the principles and targets of solid waste harmlessness,quantity reduction and recycling,the feasibility is analyzed on the coordinated utilization of solid waste from various sectors involved in industry,agriculture and urban areas in Beijing-Tianjin-Hebei Region.The overall idea and solution is proposed for the cross-industry and cross-region coordinated utilization of solid waste.The analysis suggests that,based on the solid waste database establishment,high proportion of coordinated utilization,high added-value products development,industrial materials application and new technologies&equipment for ultra-low off-gas emission shall constitute the support for the solution.The objective is to form an integrated demonstration base for solid waste coordinated treatment,optimize its economic operation indicators,explore new business operation modes,and accelerate industrial progress.In addition,all sectors of society shall,from the macro perspective of the integration of Beijing-Tianjin-Hebei region,actively formulate and implement new standards and regulations,and form a coordinated management system,to realize the cross-industry and cross-region coordinated utilization of solid waste in the Beijing-Tianjin-Hebei industrial,agricultural and urban areas,and solve the problem of solid waste treatment by industries and by regions.
