Abstract

A river sediment pollution control method solves the existing problems of being unable to quickly quantify river sediment pollution weights and formulate sediment pollution engineering strategies, and belongs to the technical field of environmental engineering. The invention includes: S1, constructing and training a gray-scale neural network model, the input of the gray-scale neural network model is the section overlying water data, sediment pollution data and river hydraulic data, and the output is the release rate of sediment pollution; S2, currently to be predicted Input the section data into the gray neural network model; S3, obtain the contribution rate η of the sediment release to the river water quality pollution, if η is less than the contribution rate set value, transfer to S2 to predict the next section, otherwise transfer to S4; S4, use the entropy weight The weight ω of each pollution factor released from the sediment was obtained by using the method j ; S5, if ω j If it is greater than the weight setting value, the corresponding sediment release pollution factor is used as the control point, and the corresponding control technology decision-making scheme is selected; S6. Integrate the control points of all sections and the corresponding control technology decision-making scheme.

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...
