包头市水质自动监测站氨氮和高锰酸盐指数的比对分析

Comparative Analysis ofStation of Ammonia Nitrogen and Permanganate Index Automatic water Quality Monitoring of Baotou

通过对内蒙古包头市环境监测站2012-2013年自动站监测的氨氮和高锰酸盐指数的监测结果和实验室手工监测结果进行比对,得出氨氮和高锰酸盐指数手工监测值和自动监测日均值、手工监测值和自动监测月均值无显著性差异且有显著线性关系,分析自动监测和手工监测结果的偏差产生的原因,氨氮、高锰酸盐指数自动监测与手工监测的比对相对误差的绝对值偏高,自动监测的结果作为定性参考值,定量必须采用实验室标准方法监测。

The Inner Mongolia environmental monitoring station of Baotou city 2012 -2013 monitoring results of manual monitoring results monitoring of ammonia nitrogen and potassium permanganate index automatic station and laboratory were compared, the ammonia nitrogen and potassium permanganate index manual monitoring and automatic monitoring of daily mean value, manual monitoring and automatic monitoring of monthly mean no significant difference and there is a significant linear relationship, the reason for the deviation analysis of the automatic monitoring and manual monitoring results, the absolute value of ammonia nitrogen, permanganate index is higher than the automatic monitoring and manual monitoring of relative error, automatic monitoring results as reference value, must use standard method of monitoring quantitative laboratory.
