Recycled water wetland water quality risk factor probability screening method

Abstract

The invention relates to a reclaimed water wetland water quality risk factor probability screening method, and belongs to the technical field of water ecological water quality screening. Establishing a screening model calculation file, carrying out Butterfly normal distribution variance homogeneity test, carrying out sequence calculation on parameters of an empirical normal distribution function, carrying out probability calculation by adopting a sequence for calculating the empirical normal distribution function, and screening the probability of the water quality risk factor. The method has the advantages that aiming at the characteristics of large information amount, large information repetition amount, strong randomness and fixed monitoring data position of water quality monitoring data, the occurrence probability and probability and possible occurrence time of various screened water quality indexes are clarified by classifying and analyzing the characteristics of the information and comparing common characteristics. The algorithm model can assist related departments in effectively utilizing monitoring data to master possible occurrence conditions of wetland water quality risk factors, determining possible probabilities and possible occurrence time of various screened water quality indexes, and evaluating possible water quality risks.
