Embodiment Construction

[0042] The method of this embodiment is based on the following research basic principles:

[0043] 1. Gini coefficient

[0044] The definition of the Gini coefficient is proposed on the basis of the Lorenz curve, the Lorenz curve is as follows figure 2 .

[0045] Use the horizontal axis to represent the cumulative percentage of population, and the vertical and horizontal axis to represent the cumulative percentage of income. The area between the real income distribution curve and the absolute equality curve of income distribution is A, and the area at the bottom right of the real income distribution curve is B. The definition of the Gini coefficient is:

[0046]

[0047] There are many calculation methods for the Gini coefficient, such as direct calculation method, regression curve method, population equal division method, and urban-rural decomposition method. Ye Liqi proposed the triangular area method and the arcuate area method. The area under the Lorenz curve is appr...

Abstract

The invention provides a multi-objective optimal distribution method for total pollutants. The method comprises the following steps: taking the annual total output value of the industry, the maximum Sand the minimum total cost G of newly added industrial pollutant treatment as target functions; using a water environment quality constraint, a water resource reasonable utilization constraint, an industry optimization adjustment constraint and an industry allocation capacity non-negative constraint as four constraint conditions; and constructing a multi-objective industry total quantity optimaldistribution model, solving an optimization problem after converting the objective function from multiple objectives into a single objective and converting nonlinear constraints into linear constraints, and obtaining pollutant total quantity multi-objective optimal distribution. A complete method for comprehensive treatment engineering implementation of multiple industries is formed, the feasibility of the total quantity optimal distribution result of all the industries is reflected systematically and visually, and the defects of the optimal distribution method in the aspect of feasibility areovercome.

Description

technical field [0001] The invention relates to an optimal allocation method, in particular to a multi-objective optimal allocation method for the total amount of pollutants. Background technique [0002] The distribution of total pollutants is the process of distributing the allowable discharge of regional pollutants (water environment capacity) to each generalized sewage outlet according to certain principles, and it is also the key technical link of "total pollutants control"; its essence is to determine the research The rights of each pollutant discharging unit in the region to use water environment resources and their corresponding reduction tasks. Commonly used methods for the allocation of the allowable discharge of pollutants (water environment capacity) include the equal-proportion allocation method, the optimal allocation model method, and the analytic hierarchy process. Among them, the equal proportion distribution method is the most widely used distribution meth...
