摘要
浔河是淮安市洪泽区重要的城市排涝河道。浔河唐曹断面溶解氧变化情况较大,特别是夏季溶解氧浓度较低,导致断面水质无法稳定达标。本文从水温、营养物质、支流来水等多方面分析浔河唐曹断面夏季溶解氧较低的原因。结果表明:浔河唐曹断面溶解氧与水温、总磷相关性较大,与氨氮相关性较小;部分支流来水质量不高,也对浔河水质产生较明显影响。
Xun River is an important urban drainage channel in Hongze District,Huai'an City.The dissolved oxygen concentration at the Xun River Tangcao section varies greatly,especially in summer when the dissolved oxygen concentration is low,resulting in unstable water quality that does not meet the standards.This paper analyzes the reasons for the low dissolved oxygen in the Xun River Tangcao section in summer from various aspects such as water temperature,nutrients,and inflow from tributaries.The results show that the dissolved oxygen in the Xun River Tangcao section is more correlated with water temperature and total phosphorus,and less with ammonia nitrogen;the inflow from some tributaries with poor quality also has a significant impact on the water quality of Xun River.
