水环境质量自动监测中溶解氧偏低的相关原因分析

Analysis of the causes of low dissolved oxygen in automatic monitoring of water environment quality

水体溶解氧是维持水中生物生存的必要条件,是衡量水体好坏的关键,更是影响水生态环境质量的重要因素。然而水体环境变化多端,且不同区域、不同地表水组成成分不同,导致溶解氧含量空间分布不均衡,不利于水体生态环境的可持续发展。为了更好地分析水质未受到污染环境下出现溶解氧快速下降又上升的原因,本文通过分析影响溶解氧的相关因素,结合影响溶解氧偏低的线性关系阐述了具体原因和对策,以供同行参考。

Dissolved oxygen in water body is a necessary condition to maintain the survival of aquatic organisms,a key to measure the quality of water body,and an important factor to affect the quality of water ecological environment.However,the water environment is changeable,and the composition of different regions and different surface water is different,resulting in the uneven spatial distribution of dissolved oxygen content,which is not conducive to the sustainable development of the water ecological environment.In order to better analyze the reasons for the rapid decline and rise of dissolved oxygen in the non-polluted water environment,this paper analyzes the relevant factors affecting dissolved oxygen,and expounds the specific reasons and countermeasures in combination with the linear relationship affecting the low dissolved oxygen for reference.
