洱海北岸弥苴河水质沿程变化特征研究

The Variation in the Water Quality along the Miju River on the North Bank of Lake Erhai

在弥苴河全程设置12个固定点位对其水质进行逐月监测,结果显示:弥苴河全年的TN年均浓度为0.899mg/L,水质类别为地表水Ⅲ类;TP年均浓度为0.080mg/L,水质类别为地表水Ⅱ类;CODCr年均浓度为12.2mg/L,水质类别为地表水Ⅰ类,其总体水质基本达到水功能类别Ⅲ类要求.

The water quality was monitored at 12 fixed places along the Miju River from December of 2010 to November of 2011.The result showed that the average annual concentrations of TN,TP and CODCr were 0.899 mg/L,0.080mg/ and L12.2 mg/L,respectively,corresponding to the standards of Class Ⅲ,Class Ⅱ,and Class I in sequence.The overall water quality of the Miju River can reach the standard of Class Ⅲ.
