摘要: 黄河流域是我国重要的生态屏障和经济地带,高质量发展对黄河流域生态环境保护和资源再生利用提出了更高的要求。固体废物兼具“资源”和“环境”双重属性以及污染“源”和“汇”双重属性,其无害化和资源化对保障黄河流域生态环境保护和高质量可持续发展意义重大。本文系统阐述黄河流域不同类型固体废物产生量和利用处置能力的空间分布和时间演化特征,在此基础上,进一步分析发现黄河流域固废污染防治存在的问题,包括产业结构偏重、固废增量存量压力大,无害化处置存在短板弱项,底数不清、环境风险较大,流域上下游、固废水气以及污染物和温室气体等协同治理不足。
;根据流域资源禀赋、自然条件和行业产业特征,以减污降碳协同增效为目标,建议以“无废流域”建设为抓手,推动绿色低碳循环发展,补齐利用处置能力短板,着力防范重点领域风险,推进固体废物协同治理等。Abstract: The Yellow River Basin is an important ecological barrier and economic zone in China. High-quality development puts forward higher requirements for ecological environment protection and resource recycling in the Yellow River Basin. Solid wastes have the dual attributes of "resources" and "environment" and the dual attributes of "sources" and "sinks" of pollution. Its harmlessness and resource utilization are of great significance to the protection of ecological environment and high-quality sustainable development in the Yellow River Basin. This paper systematically expounds the spatial distribution and temporal evolution characteristics of different types of solid wastes in the Yellow River Basin. On this basis, it further analyzes the existing problems in the prevention and control of solid wastes in the Yellow River Basin, including heavy industrial structure, high pressure of solid wastes' incremental stock, shortcomings of harmless disposal, unclear base number, high environmental risk, and insufficient collaborative treatment of upstream and downstream of the basin, solid wastewater gas, pollutants and greenhouse gases. ; According to the basin resource endowment, natural conditions and industrial characteristics, with the goal of reducing pollution and carbon, it is suggested that the construction of "waste-free basin" should be taken as the starting point to promote the development of green and low-carbon cycle, make up the shortcomings of utilization and disposal capacity, focus on preventing risks in key areas, and promote the collaborative treatment of solid wastes.-
