The total amount control method of pollutants under the condition of large-scale planar grid

Abstract

The invention discloses a pollutant total-amount control method under the large-scale planar grid condition. The pollutant total-amount control method includes the steps of determining the pollutant total-amount control range and pollutant total-amount control pollutants; determining generalized pollution sources, the minimum value and the maximum value of distributed amounts of the generalized pollution sources and a water-area water-quality concentration target value; building a water quality model, and calculating the water quality response fields of the pollutants corresponding to the pollution sources within the total-amount control range; determining an objective function and constraint conditions of pollutant total-amount distribution, building a pollutant total-amount distribution model with a linear planning method, calculating pollution-source distribution loads after constrain equations of redundancy points in the model are removed, and controlling the pollution-source total amount with the pollution-source distribution loads. The applicability of the pollutant total-amount control method under the large-scale planar grid condition can be improved.

Description

technical field [0001] The invention relates to a method for controlling the total amount of pollutants in a water environment, in particular to a method for controlling the total amount of pollutants under the condition of a large-scale plane grid. Background technique [0002] Since the "Sixth Five-Year Plan" period, my country has included the research on the control of the total amount of pollutants in the water environment as a national environmental protection science and technology project, and the country has attached great importance to the control of the total amount of pollutants. During the "Twelfth Five-Year Plan" period, the Ministry of Environmental Protection included chemical oxygen demand and ammonia nitrogen in the total control targets of water environmental pollutants. The "National Environmental Protection "Twelfth Five-Year" Plan" issued by the State Council requires: "Implement total nitrogen or total phosphorus discharge control in eutrophic lakes an...

Problems solved by technology

This means that there are tens of thousands or even hundreds of thousands of constraint equations (mathematical expressions of constraints) in linear programming. Such a large constraint condition brings great difficulties to the solution.
