地表水中化学需氧量、高锰酸盐指数和五日生化需氧量的相关性研究分析

Correlation Analysis of Chemical Oxygen Demand, Permanganate Index and Oxygen Demand after 5 Day s Demand in Surface Water

本文通过使用广东省某地区历史的地表水数据对水环境监测主要指标五日生化需氧量、高锰酸盐指数和化学需氧量三项指标的相关性进行分析。已知三者存在一定的(线性)比例关系,如何并通过三者之间存在的规律性及关联性在监测过程中更好的利用其中关键性关联性,进行分析,确保监测数据的有效准确快捷,以便环境保护部门可以更科学精准的开展环境治理、环境污染源头管控、环境影响评价以及判断未来的环境变化趋势等众多方面发挥积极有效的作用,从而改善人居环境。

Based on the historical surface water data of a certain area in Guangdong Province, this paper analyzes the correlation among the main indexes of Water Environmental Monitoring, Oxygen demand after5 days, permanganate index and Chemical Oxygen Demand Index. It is known that there is a certain(linear)proportional relationship between the three. How to make better use of the key correlation in the monitoring process through the regularity and correlation between the three, and conduct analysis to ensure the effectiveness, accuracy and rapidity of the monitoring data, so that the environmental protection department can carry out environmental governance, environmental pollution source control and Environmental impact assessment and environmental monitoring play an active and effective role in judging the change trend of pollution, so as to improve the living environment.
