Abstract
In this paper, the water quality comprehensive index model is used for scenario innovation. Combined with the characteristics of stable physical environment of water quality in the pipeline, the pipeline water quality model PWQI is developed based on the integrated learning algorithm. The model selects 17 pipeline water quality parameters and divides them into 5 categories. In order to avoid the single weighting of water quality parameters, the combination weighting of water quality parameters is carried out by expert opinion and entropy weighting method. The CatBoost algorithm is used for regression prediction. Compared with the traditional water quality assessment method, the results show that the PWQI model has the most notable prediction effect on the pipeline water quality, which can accurately reflect the water quality of the pipeline and provide a basis for pipeline water quality assessment.
