红河流域元江县域内几种污染物变化规律探讨

Study on the Variation Law of Several Pollutants in Yuanjiang County in the Honghe River Basin

以2014—2017年元江县环境监测站对元江河入境断面和出境断面的监测数据为依据,分析探讨几种污染物随季节的变化规律。结果表明,COD值>BOD值>高锰酸盐指数值,COD污染受季节性变化最明显,BOD、高锰酸盐指数和氨氮的值也是第二季度明显高于其他季度。提出了对策建议。

According to the monitoring data of the in-and-out boundary sections of Yuanjiang River in Yuanjiang County from 2014 to 2017, the paper analyzed and discussed the seasonal variations of several pollutants. The results showed that the COD value was higher than BOD value and permanganate index value. The COD value indicated the most obvious seasonal variation, and the values of BOD, permanganate index and ammonia nitrogen were also significantly higher in the second quarter than in other quarters. Countermeasures were put forward.
