针对高溶解氧、高锰酸盐指数的地表水水质评估方法研究

在进行水体研究的过程中,选择适当的评估方法对水体进行评估必不可少。为寻找更加适用于高溶解氧、高锰酸盐指数较高的水体的水质评估模式,在分析现有水质评估方法的基础上,对评价安全性最高的单因子评价法和最能体现生态修复能力的有机污染综合指数评价法进行了比较分析,建立了单因子-有机污染综合指数耦合方法,建立了基于两种方法联合使用的水质分析模式。利用监测数据,分析了该模型应用于高溶解氧与高锰酸盐指数的地表水水质评估的可行性。结果表明,该方法适用于高溶解氧、高锰酸盐指数的地表水水质评估。

Investigation on Water Quality Assessment Model of Surface Water with High Dissolved Oxygen and Potassium Permanganate Index

In the process of water research, selection of appropriate evaluation method of the water quality assessment is indispensable. In order to assess the quality of water with high dissolved oxygen and potassium permanganate index, both of the evaluation methods of single factor and the organic pollution comprehensive index were compared by analyzing existing water quality analysis and evaluation methods. The former which is known for its highest safety and the latter that better reflect the ecological restoration ability were compared. The coupling method of single factor and organic pollution comprehensive index was established as the water quality analysis mode, in view of the combined use of the two methods. The monitoring data was used to assess the accuracy and feasibility of applying this model to analyze the water quality of high dissolved oxygen and potassium permanganate index. Results showed that the method was applicable to the water quality assessment of surface water with high dissolved oxygen and potassium permanganate index.
