城市雨水径流中新污染物的赋存与去除技术研究进展

Research Progress on Occurrence and Removal Technology of Emerging Contaminants in Urban Stormwater Runoff

随着城市化进程的加速,雨水径流污染成为全球环境关注的焦点。除了传统污染物外,新污染物如持久性有机污染物、内分泌干扰物、抗生素和微塑料等受到日益关注。文章系统梳理了雨水径流中新污染物的种类、赋存情况及对环境的影响,并分析了相关去除技术的研究进展。持久性有机污染物在雨水径流中的来源多样,土地利用类型对其浓度有显著影响。由于内分泌干扰物的广泛使用,其已成为雨水径流中的重要污染物。抗生素和微塑料作为新污染物,其在雨水中的赋存和影响也逐渐受到关注。针对这些污染物,物理、化学、生态等多种去除技术被研究和应用,包括砂滤池、化学氧化、生物滞留池等。此外,源头管控也是减少雨水径流污染的重要手段,包括城市管理和规划、化学品使用管控和废物处理等。未来研究应加强对新污染物的监测与评估,并结合多种技术手段实现雨水径流污染的有效治理。

With the acceleration of urbanization,stormwater runoff pollution has become a global environmental focus.In addition to traditional pollutants,emerging contaminants such as persistent organic pollutants,endocrine disruptors,antibiotics,and microplastics are receiving increasing attention.This paper systematically reviews the types,their occurrence and their environmental impacts of emerging contaminants in stormwater runoff,and analyzes the research progress of related removal technologies.Persistent organic pollutants in stormwater runoff come from diverse sources,and land use types have a significant impact on their concentrations.Endocrine disruptors have become important pollutants in stormwater runoff due to their widespread use.Antibiotics and microplastics,as emerging pollutants,are also gradually receiving attention for their occurrence and impacts in stormwater.Various removal technologies including sand filters,chemical oxidation,and bioretention ponds are being researched and applied for these pollutants.Additionally,source control is an important means to reduce stormwater runoff pollution,including urban management and planning,chemical use control,and waste treatment.Future research should strengthen monitoring and assessment of emerging contaminants and combine multiple technological approaches to achieve effective management of stormwater runoff pollution.
