湘潭地区高锰酸钾法地表水检测分析

摘要

为了监测湘潭地区水体受有机物污染程度,采用酸性高锰酸钾法对该地区地表水中化学需氧量数值进行了检测分析.对比近两年来各断面的年平均化学需氧量数值,各断面化学需氧量数值整体呈下降趋势,水体逐渐趋于清洁,且均符合《地表水环境质量标准》(GB3838-2002)Ⅲ类水质标准.但仍有部分地区有机物污染较严重,需继续加强治理.%In order to monitor the degree of organic pollution of the water in Xiangtan area,the chemical oxygen demand (COD) of surface water in this area was detected by acid potassium permanganate method.The average annual chemical oxygen demand in the past two years was compared.The results show that the chemical oxygen demand of the whole section shows a decreasing trend,and the water body tends to be clean.And they all conforms to the surface water environmental quality standard (GB3838-2002) class Ⅲ water quality standard.But there are still some areas whose organic pollution is serious,the control should be strengthened.
