In the spring,water quality anomalies were observed in various river sections in Dalian,including the Densha River,Yingna River,and Fuzhou River,with elevated pH and permanganate index levels.This article focuses on the Dengsha River,providing a comprehensive analysis of the water quality changes.By considering data trends,the photosynthetic mechanisms of algae,and the growth and metabolic patterns of algae,an in-depth analysis of the reasons for the exceedances are offered.Both short-term and long-term measures are further proposed to ensure that the water quality meets national standards.
