Embodiment Construction

[0079] According to the investigation of 11 sewage outlets along the river in a section of the Three Gorges Reservoir area, a comprehensive evaluation of the sewage outlets was carried out, and on this basis, the sewage discharge situation in the area was optimized. The specific implementation steps are as follows:

[0080] 1) Determine the evaluation index

[0081] The present invention starts from three aspects of the social, economic and environmental benefits of the sewage outlet, and constructs a comprehensive evaluation index system containing 12 evaluation indexes. The specific data are shown in Table 1

Abstract

The invention discloses a regional water pollution comprehensive evaluation and optimization method based on an entropy weight fuzzy matter element method. A quantification method is adopted for constructing a comprehensive evaluation model of a regional water pollution emission source, and a linear programming model with optimal regional water environment comprehensive effects is established according to the comprehensive evaluation result. The method comprises the steps of establishing a fuzzy matter element model, performing weight calculation through an entropy weight method, determining a regional major emission source and establishing a regional emission source optimization model. According to the method disclosed by the invention, a matter element theory is used as an evaluation tool for the water pollution emission source, and good evaluation of the water pollution emission source is further realized. The objectivity in comprehensive evaluation of the water pollution emission source is realized: system optimization is performed on the basis of comprehensive evaluation, the comprehensiveness of a system is considered to the greatest extent, and the optimization result is more in line with the practical application situation. The established evaluation decision-making method is clear and visual in concept; and furthermore, the calculation process is simple, and computer programming calculation is easy to realize.

Description

technical field [0001] The invention belongs to regional water pollution source evaluation and regional water pollution optimization control, and can be applied to regional water pollution prevention and control plan formulation period to evaluate the importance of regional pollution sources and control priorities, and provide optimization plans to provide decision-makers with technical Support; it can also be applied to the comprehensive evaluation and optimization of existing water pollution discharge sources to achieve the optimal state of regional water pollution control. Background technique [0002] The evaluation and management of regional water pollution discharge sources is a systematic project involving many factors. In practical problems, there are many regional sewage discharge sources and their layout positions are different. The characteristics of the sewage discharged by each sewage outlet are different. Differences in hydraulic conditions at the location. Ho...
