Comparative Study of Colloidal Particles on Organic Matter Degradation in Environmental Water and Typical Urban Sewage

Abstract

Water, as a critical natural resource in urban areas, faces severe pollution due to human production and living activities. Previous studies have shown that dissolved organic matter (DOM) significantly affects water quality. To deepen our understanding of the impact of colloidal particles on DOM, we conducted a comparative study on organic matter degradation by colloidal particles in environmental water and typical urban sewage. The experiments revealed that colloidal particles accelerate the photodegradation of DOM in all six experimental water bodies. This research is pivotal for solving the challenges of water pollution confronting society.
