River single factor water quality mark index number evaluation method

Abstract

This invention is an appraising method about single gene water quality identifying parameter to river. It refers to a new appraising method about single index of water quality. This invention uses the single gene water quality identifying parameter to identify single index of water quality. The single gene water quality identifying parameter is characterized as following: P =X X X. Here Pi represents the number i single gene water quality identifying parameter of water quality; X1 represents that which sort of water quality the number i the single index of water quality identifying parameter belongs to; X2 represents that which level the single index thickness of water quality at in the arrange of the sort of X1, getting one digit integer following the principle round; X represents one or two validities. The invention could perfectly identifies which sort the water quality identifying parameter belonging to, data of water quality, target value in the region of function and other important information. It not only shows intuitionisticly the differences in water quality, but also reflects complexion of reaching standard: identifying by both determining the nature and fixing quantify.

Description

technical field [0001] The invention relates to a single-factor water quality identification index evaluation method for a river, which relates to a new single-index water quality evaluation method. Water quality evaluation is a basic work in water environment governance and monitoring. Only by making a reasonable evaluation of water quality through water quality monitoring can we formulate targeted water environment governance plans and programs. It can be said that the rationality of water quality evaluation will directly affect water quality. environmental management decisions. Background technique [0002] Water quality evaluation is divided into single index water quality evaluation and comprehensive water quality evaluation. There are two typical methods for evaluating the water quality of individual indicators: one is to compare the actual measured value with the limit value of the basic items in the national standard according to the national "Surface Water Environm...

AI Technical Summary

Problems solved by technology

[0003] Both of the above two typical methods have certain deficiencies. Evaluation according to national standards cannot evaluate the quality of water in the same category; evaluation according to the single pollution index method cannot explain the category of water quality.
