River sediment pollution control method

Abstract

The invention discloses a river sediment pollution control method, solves the problems that the river sediment pollution weight cannot be quickly quantified and a sediment pollution engineering strategy cannot be formulated in the prior art, and belongs to the technical field of environmental engineering. The method comprises the steps of: S1, constructing and training a gray neural network model, wherein the input of the gray neural network model is section overlying water data, bottom mud pollution data and river hydraulic power data, and the output of the gray neural network model is bottom mud pollution release rate; S2, inputting current to-be-predicted section data into the gray neural network model; S3, obtaining a contribution rate [eta] of sediment release to river water quality pollution, if [eta] is smaller than a contribution rate set value, turning to S2 to predict a next section, and otherwise, turning to S4; S4, obtaining the weight [omega]j of each pollution factor released by the bottom mud by using an entropy weight method; S5, if [omega]j is larger than a weight set value, serving the corresponding sediment release pollution factor as a control point, and selecting a corresponding control technology decision scheme; and S6, integrating the control points of all sections and corresponding control technology decision schemes.

Description

technical field [0001] The invention relates to a river sediment pollution control method based on a gray neural network fusion entropy weight method, which belongs to the intersection fields of municipal engineering, environmental engineering, environmental system simulation prediction technology and computer technology. Background technique [0002] River water is an important part of the human living environment. It has many ecological and social functions such as ecological habitat, water resource accommodation, and shipping passage, and is closely related to human activities. However, with the rapid development of my country's economy and the acceleration of urbanization, river pollution incidents caused by eutrophication of water bodies and excessive heavy metals have occurred from time to time. River pollution control has increasingly become one of the important ecological construction tasks in the process of urban development. [0003] Studies have shown that the sou...
