Embodiment Construction

[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples serve to illustrate the present invention, but do not limit the scope of the present invention.

[0033] The present invention applies stochastic simulation technology to the distributed water environment model of the watershed, calculates the confidence level of water quality compliance under specific pollutant discharge scenarios, and further utilizes artificial neural network methods to establish the relationship between pollutant discharge scenarios and compliance confidence levels. Mapping relations. By using the established mapping relationship, it is convenient to evaluate and screen the total emission reduction scheme. This method can be programmed and calculated with Matlab scientific computing software, and its concrete steps are as follows (as figure 1 shown):

Abstract

The invention discloses a method for controlling the total amount of catchment pollutants under uncertain conditions. The method comprises the following steps of: S1, establishing a catchment distributed water environment model and developing a data interface; S2, carrying out random simulation with a management target as a guide; S3, calculating a confidence level achieved by a water quality management object; S4, establishing a mapping relationship between a pollution loading amount scene and the confidence level; and S5, evaluating and screening a total amount control scheme of the catchment pollutants under the uncertain conditions and carrying out the total amount control of the catchment pollutants by using the screening scheme. According to the method disclosed by the invention, the catchment distributed water environment model, a random simulation technology and an artificial neural network method are effectively integrated; the method for reasonably determining the reducing amount of the pollutants under the uncertain conditions is established; and the important significance for the total amount control of the catchment pollutants under the uncertain conditions is realized.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to a method for controlling the total amount of watershed pollutants under uncertain conditions. Background technique [0002] The global water environment is facing serious threats from human activities, and the prevention and control of water pollution in river basins has received widespread attention. In developed countries, with the improvement of the control level of industrial and urban point source pollution, non-point source pollution (such as agricultural non-point source pollution) has become the primary threat to the water environment. In my country, however, the task of controlling point source emissions is still arduous, and the problem of non-point source pollution is becoming increasingly prominent. The total amount control of watershed pollutants has become an international consensus and has become an important link in the water environ...
