摘要

随着“双碳”目标的提出,传统污染源治理技术在碳污协同减排和多介质污染协同控制等方面面临诸多挑战,亟需探索环境治理新范式。针对城市环境复合污染治理难题,将污染控制由排放源拓展至环境过程,论述了通过人工手段强化城市环境的自净功能,利用自然界的光、热、风、氧、水等条件实现污染物的环境过程净化,耦合气-水-土多介质人工强化环境自净技术构建“自净城市”,有望成为环境保护工作新的增长点,巩固当前污染源排放控制的成果,保障环境质量持续改善。在此基础上,对污染物环境过程净化、自净城市的理论与技术进行了介绍,并对相关研究工作进行了展望。

Abstract

With the pollution control of China entering a critical stage and the proposal of "dual carbon" targets, traditional pollution control technologies face numerous challenges in terms of synergistic reduction of carbon and pollutant emissions and
coordinated control of pollutions in multiple media. There is an urgent need to explore a new paradigm for pollution control. To tackle the complex issue of urban environmental pollution, this work expands pollution control efforts from emission sources to environmental processes, offering a promising new approach.The self-purification function of urban environment can be enhanced through artificial technologies, and the pollutants can be purified in environmental processes under natural conditions by light,heat, wind, oxygen, and water. Furtherly, through coupling the artificial enhanced environmental self-purification technologies for gas-water-soil multi-medium, a "self-purifying city" can be constructed. The artificial enhanced self-purification technologies and "self-purifying city" would provide a new growth point for environmental protection, consolidate the current achievements of pollution source emission control, and ensure the continuous improvement of environmental quality. This paper introduces the theories and technologies of artificial enhanced self-purification and "self-purifying city" and provides an outlook on future research in this area.
