摘要
水环境中污染物的治理是保护水资源的关键,了解污染物的来源、组成及其迁移和转化过程将更好地指导污染物的高效去除。本研究分析了工业废水、生活污水和农业面源污染三种主要污染源的污染物质组成,并详细阐述了污染物质在水体中的对流扩散、挥发、络合、生物富集等迁移机制。同时,探讨了吸附-解吸、氧化还原反应、微生物降解等多种污染物转化与去除方式。该篇文章为水环境中污染物的有效治理提供了充足的科学依据,有助于推动水体污染控制技术的进步,实现水资源的可持续利用。
The management of pollutants in the water environment is the key to the protection of water resources,and an understanding of the sources and compositions of pollutants as well as their migration and transformation processes will better guide the efficient removal of pollutants.In this study,we analyzed the composition of pollutants from three major pollution sources,namely industrial wastewater,domestic sewage and agricultural surface pollution,and elaborated on the migration mechanisms of convective diffusion,volatilization,complexation and bioconcentration of pollutants in the water body.At the same time,a variety of pollutant transformation and removal modes such as adsorption-desorption,oxidation-reduction reaction,and microbial degradation are discussed.This article provides sufficient scientific basis for the effective management of pollutants in the water environment,which helps to promote the progress of water pollution control technology and realize the sustainable use of water resources.
