技术预见是制定科技发展战略和科技政策的重要基础，德尔菲调查是技术预见中最常用的方法。本研究通过文献分析、专家建议、会议讨论等方法，从大气污染防治、水污染防治、固体废弃物污染防治与资源化、土壤污染防治、生态保护与恢复、环境监测预警与风险控制、资源利用与清洁生产7个子领域提出我国环境工程领域的45项备选技术。根据德尔菲法的调查结果，初步筛选出2035年我国环境工程科技发展的关键技术、共性技术以及颠覆性技术，分析了技术实现时间、发展水平与制约因素，为未来20年我国环境工程科技发展战略和目标的制定提供参考。

The Delphi method is the most common method of technology foresight, which is a significant basis for establishing development strategies and policies of science and technology. This study proposes 45 alternative technologies in the field of environmental engineering science and technology through a literature survey, experts' advice, and discussion meetings. These technologies relate to air pollution prevention and control; water pollution prevention and control; soil pollution prevention and control; solid waste pollution prevention, control, and utilization; ecological protection and restoration; environmental monitoring, early warning, and risk control; resource utilization and cleaner production. Based on results that were obtained according to the Delphi method, this research analyzes the realization time, R&D level, and restriction factors for the key technologies, common technologies, and disruptive technologies that were determined for 2035. This study provides a reference for establishing development strategies and objectives for China’s environmental engineering science and technology over the next 20 years.
