Type: book-chapter
Abstract: Domestic sewage has always been one of the main causes of river pollution.In this paper, a weighted grey correlation model is established to judge the influence of many factors, including domestic sewage, on river pollution.In the process of establishing the model, the AHP analytic hierarchy process is used to calculate the weight of each influencing factor, and the consistency test is used to judge the feasibility of the weight.This paper also establishes a prediction model of domestic sewage discharge based on GM(1,1) model, the average prediction error of this model is only 0.43%, which proves the superiority of the prediction model.
