Application of Improved Comprehensive Pollution Index Method in Water Quality Assessment of Tuhai River
In order to make the comprehensive pollution index method better applied to water quality assessment,this paper improves the method,gives the method of establishing the standard limit value of the comprehensive pollution index,and establishes the relationship with the water quality categories in the surface water environmental quality standard,so that it can not only reflect the comprehensive impact of each water quality index on the river water quality,but also make a qualitative judgment on the water quality categories.The improved method is applied to the Tuhai River,and the comprehensive water quality and main pollution indicators of the Tuhai River are obtained.The results are compared with the single factor evaluation method,and the results of the method are consistent with the single factor evaluation results,which further verifies the reliability of this method.
