摘　　要：随着城市化进程的加快,城市河流中的重金属污染问题日益严重,成为环境保护和公共健康的重要挑战。本文通过对城市河流重金属污染现状的分析,探讨了重金属污染的主要来源及其传播机制,重点评估了现有的治理技术。研究发现,工业排放、城市排污、农业活动和交通排放是重金属污染的主要来源。本文还基于对各种治理技术的评估,提出了智能沉淀技术、高效过滤介质、动态吸附系统、微生物修复技术、基因改造植物修复以及纳米技术沉淀剂和电化学沉淀法等治理对策,以期为改善城市河流的水质提供参考。With the acceleration of urbanization,the issue of heavy metal pollution in urban rivers has become increasingly severe,posing significant challenges to environmental protection and public health.This paper analyzes the current state of heavy metal pollution in urban rivers,explores the main sources of heavy metal pollution and its transmission mechanisms,and evaluates existing remediation technologies.The study finds that industrial emissions,urban sewage discharge,agricultural activities,and traffic emissions are the primary sources of heavy metal pollution.Based on the evaluation of various remediation technologies,countermeasures such as intelligent precipitation technology,efficient filtration media,dynamic adsorption systems,microbial remediation technology,genetically modified plant remediation,as well as nanotechnology-based precipitation agents and electrochemical precipitation methods are proposed,aiming to provide a reference for improving the water quality of urban rivers.
