大连市河流pH、高锰酸盐指数超标原因机制分析——以登沙河为例

进入春季,大连市登沙河、英那河以及复州河等多条河流相关断面发生pH和高锰酸盐指数异常超标的现象。以登沙河为例,全面分析断面水质的变化情况,并结合数据演变趋势、藻类光合作用机制以及藻类自身生长和代谢规律等,综合分析水质参数超标原因,并有针对性地提出了近期和远期治理措施,以满足国家对水体中各项参数达标的管控要求。

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.
