Abstract
(EN)
The present invention relates to the field of environment monitoring. The present invention solves the problem in the prior art of large errors arising when using spectrophotometry to monitor a water quality COD index, and provides a method for constructing a water quality index prediction model and a method for monitoring a water quality index. The technical solution thereof can be summarized as follows: a method for constructing a water quality index prediction model, comprising: acquiring multiple water samples as water inspection samples, and acquiring respective required water quality indexes for the water inspection samples; measuring, for each of the water inspection samples, a spectrum corresponding thereto, obtaining an original spectrum, and acquiring a physical parameter thereof; conducting at least two digestions on the water inspection samples, measuring a spectrum corresponding thereto after each of the digestions to obtain a digestion spectrum, and acquiring a digestion parameter of the digestion and a physical parameter of the water inspection samples after the digestion; and independently constructing, according to data collected from each of the water inspection samples, an individual water quality index prediction model for each of the required water quality indexes. The present invention has an advantageous effect of fundamentally reducing measurement errors, and is applicable to water quality index monitoring.
