[0059] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0060] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0061] Water environmental capacity refers to the maximum load of pollutants that a water body can accommodate while meeting water quality requirements. It is also known as water loading capacity or pollution absorption capacity. It consists of two parts: dilution capacity and self-purification capacity. Dilution capacity refers to the amount of pollutants that a given water body can accommodate to achieve water quality targets through dilution when the background pollutant concentration in the water body is lower than the water quality target. Self-purification capacity refers to the amount of pollutants that can be self-purified in a given water body to achieve water quality targets through physical, chemical, and biological processes such as sedimentation, biochemical reactions, and adsorption.

[0062] Water environmental capacity is an objective resource that exists independently of current emissions, relying solely on water volume and self-purification capacity. Therefore, calculating water environmental capacity is simplified. Water environmental capacity is related to factors such as the characteristics of the water area, environmental function requirements, types of pollutants, and discharge methods. It serves as one of the foundations for developing local and specialized water discharge standards, and also serves as the basis for environmental management departments to determine the amount of pollutants permitted to be discharged into a water area. Water environmental capacity can be calculated using a water quality model, which includes the calculation of differential capacity and assimilation capacity. Differential capacity refers to the difference between the original (initial or background) pollutant load in a water body and the pollutant load determined by the water quality target. Assimilation capacity refers to the amount of pollutants reduced by the water body's self-purification or assimilation capacity. Therefore, the river water environmental capacity model proposed in this application is calculated based on actual monitored information, with hydrodynamic model and water quality model calculations performed in batches. The final water environmental capacity model is obtained by optimizing the hydrodynamic model first and then the water quality model.

[0063] Figure 1 A flow chart of a method for constructing a river water environment capacity model of the present application is shown.

[0064] like Figure 1 As shown, the present application discloses a method for constructing a river water environment capacity model, comprising the following steps:

[0065] S102, acquiring target data, wherein the target data at least includes river network topography data, river water conservancy project data, and river hydrological and water quality data;

[0067] S106: constructing a river water environment capacity model based on the prepared target file and the initialization model, including constructing a hydrodynamic model and a water quality model.

[0068] It should be noted that, in this embodiment, the river water environment capacity model finally constructed is a water quality model that is further calculated on the basis of the constructed hydrodynamic model, wherein, when constructing the model, basic data must be obtained first. Accordingly, the steps for obtaining the basic data are as follows: obtaining target data, wherein the target data at least includes river network topography data, river water conservancy project data, and river hydrological and water quality data; and then preparing a target file based on the target data, wherein the target file at least includes a river network file, a river section file, and a boundary condition file. The target file proposed in this application is the basic data. The model calculation is realized by combining the river information data input by the user with the actually monitored hydrological data, and the distribution optimization of the model is used to make the final river water environment capacity model more reasonable.

[0069] According to an embodiment of the present invention, acquiring target data specifically includes:

[0070] Based on the input data from the user end, the inland river information data, river section data, and sluice pump station data are obtained;

[0078] A communication connection is established with a second sensor group disposed at a preset position in the outer river, thereby obtaining the outer river tide level based on communication data of the second sensor group.

[0079] It should be noted that, in this embodiment, water level parameters can be obtained through sensors. Therefore, a communication connection is established with a first sensor group set at a preset position in the inner river, so that the water level of the inner river is obtained based on the communication data of the first sensor group; and a communication connection is established with a second sensor group set at a preset position in the outer river, so that the tide level of the outer river is obtained based on the communication data of the second sensor group.

[0080] In addition, the water quality index can also be obtained through sensors, including at least one water quality index monitoring sensor to obtain the corresponding water quality index. The specific implementation steps are similar to the steps for obtaining the water level parameters and will not be repeated here.

[0090] It should be noted that, in this embodiment, the calculation of the initial hydrodynamic calculation model based on the river network file and the river section file is specifically described, wherein each calculation result needs to be verified with the actual result, so as to perform iterative optimization. When the final hydrodynamic verification result meets the requirements, the calculation is stopped, and the hydrodynamic model is obtained based on the current calculation model. For example, when the error between the hydrodynamic calculation result and the actual result is within the range of "2%", the calculation can be stopped, and the hydrodynamic model is obtained based on the current iterative model. The initialization model is the general hydrological calculation model, and the specific calculation steps are known means to those skilled in the art and will not be repeated here.

[0094] Verification is performed based on each calculation result and the actual result until the water quality verification result meets the requirements, then the calculation is stopped and the water quality model is obtained based on the current calculation model.

[0095] It should be noted that, in this embodiment, after obtaining the optimized hydrodynamic model, it is used as the initial model for water quality calculation, so that iterative calculations are performed with the river network file, the river section file, and the boundary condition file as the input data of the initial model for water quality calculation, and each calculation result is verified with the actual result until the water quality verification result meets the requirements, and the calculation is stopped, and the water quality model is obtained based on the current calculation model, wherein the water quality verification result must be within a water quality index, and the error of the water quality verification result is "5%".
