溶解性有机质对低影响开发设施运行影响的研究进展

低影响开发(LID)设施在治理城市内涝和径流污染中发挥重要作用，在我国海绵城市建设中应用广泛。溶解性有机质(DOM)是一类具有较强的吸附、络合作用的溶解态物质，其质量占比高达径流污染物的50%以上。为阐明DOM对LID设施运行的影响，结合国内外研究现状及进展，综述DOM自身性质及其对LID设施中重金属(HMs)、持久性有机物(POPs)的归趋以及对微生物环境的影响，指出DOM会通过吸附、络合与HMs、POPs作用，造成LID设施填料吸附位点饱和、填料堵塞、微生物相对丰度(RAs)改变等。本研究旨在为LID设施设计和运行优化提供参考。

Influence of dissolved organic matter on operation of low impact development facilities

Low impact development (LID) facilities are considered significant in controlling urban waterlogging and runoff pollution, which are extensively used in the sponge city construction in China. Dissolved organic matter (DOM) is a kind of dissolved substances with strong adsorption and complexation, accounting for more than 50% of runoff pollutants. For the purpose of exploring the influence of DOM on LID facilities, the properties of DOM itself, the effect of DOM on heavy metals (HMs) and persistent organic pollutants (POPs) in LID facilities as well as its impact on microbial environment were summarized in this paper with the latest research status quo and progress at home and abroad. It is pointed out that DOM will interact with HMS and POPs through adsorption and complexation, resulting in saturation of media adsorption sites in LID facilities, blockage of media, and changes in microbial relative abundances (RAs), etc.This study is expected to provide optimization reference for the design and optimization operation LID facilities.
