[0002] With the development of industrialization and urbanization, water pollution is becoming increasingly serious. In order to effectively manage and control water quality, it is necessary to monitor pollutants in water in real time.

In addition, traditional water quality simulation methods only simulate water quality without considering the impact of sewage discharge operations in sewage pipes in water areas on water quality. Therefore, the development of a simple and efficient spatiotemporal simulation display system based on two-dimensional water quality simulation methods is of great significance for water quality management.

BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings;

[0040] Figure 1 It is a schematic diagram of the spatiotemporal simulation display system based on the two-dimensional water quality simulation method in the present invention. DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1

[0043] The spatiotemporal simulation display system based on the two-dimensional water quality simulation method includes a data collection module, a water quality monitoring module, a classification module, a comprehensive analysis module, a spatiotemporal simulation module, an evaluation module, and a display module; the data collection module, the water quality monitoring module, the classification module, the comprehensive analysis module, the spatiotemporal simulation module, the evaluation module, and the display module are communicatively connected.

[0044] The selection of water body models is based on the following considerations: 1. Spatial complexity: The two-dimensional model can simultaneously consider the changes in the length and width of the water body, which is crucial for studying grids with complex geometric shapes such as curved rivers, lakes, and near-shore waters. It allows the simulation of water flow and pollutant transport in the lateral and longitudinal directions, and more accurately reflects the actual flow conditions; 2. Hydrodynamic simulation: One-dimensional models usually assume that water flows only along the axis of the river or the main flow direction, ignoring lateral flow and mixing, while two-dimensional models can simulate the flow velocity distribution perpendicular to the main flow direction, as well as the complex flow field caused by changes in the river's banks and bottom terrain; 3. Diffusion of pollutants: In real water bodies, pollutants not only diffuse along the direction of the water flow, but also diffuse and mix on the cross-section perpendicular to the flow direction. The two-dimensional model can better describe this cross-section pollutant distribution and diffusion process; 4. Boundary condition processing: 2 The two-dimensional model can define and process various boundary conditions in more detail, such as inflow / outflow boundaries, water level fluctuations, rainfall infiltration, terrain changes, etc., so that the simulation results are more in line with the actual situation; 5. Environmental management decision-making: For environmental management and planning, it is very important to understand the specific concentrations of pollutants in different locations. The high-resolution data provided by the two-dimensional model can help decision makers formulate more reasonable water quality management plans and emergency response strategies; 6. Scientific research and education: In the field of scientific research and education, the two-dimensional model provides more details and the possibility of in-depth understanding, which helps to reveal the inherent mechanism of pollutant transport and transformation and enhance the understanding of the water environment system; and under reasonable simplification, the two-dimensional model can obtain the required results faster than the three-dimensional model, and greatly save computing resources, which makes the two-dimensional model have higher efficiency and practicality in practical applications. Therefore, the two-dimensional model is adopted in the present invention.

[0045] The space-time simulation module is used to grid the target water quality area, obtain the grid division results and transmit them to the data collection module and the water quality monitoring module; the target water quality area is divided according to the preset standards to obtain multiple separate grids, each grid will be assigned a number, and all numbers are continuous to facilitate subsequent data collection and analysis. The purpose of this division is to ensure that the water conditions of each grid are approximately consistent as much as possible. The standards and methods of division can refer to the two-dimensional water quality simulation method in the prior art, which is the prior art and will not be elaborated on here.

[0046] The data collection module is used to collect emission data for each grid in the grid division result, and then summarize all the collected emission data to obtain an emission data set and transmit it to the evaluation module; the specific implementation method is: the emission data in each grid in the grid division result is collected according to the preset time window, and the emission data contains data corresponding to m emission indicators. According to the classification of emission indicators, the emission data is marked as PFm, m = 1, 2, 3, 4, ..., a, a is a positive integer, and an example is given as: from a mechanical point of view, some substances mixed into the water body can significantly affect the density of the water, thereby affecting the mechanical properties of the water body; while some substances will not, therefore, the former is called dynamically active substances and the latter is called dynamically inert substances. Dynamically inert substances are pollutants with a density equivalent to that of the ambient water. Their mixing does not affect the original dynamic characteristics of the ambient water. It is not necessary to separate them from the ambient water when taking particles for mechanical analysis. Dynamically active substances will change their dynamic characteristics after intervening in the ambient water, such as cooling water discharge or the invasion of density flow. From a physical and biochemical perspective, some substances mixed into the ambient water will cause biochemical reactions or biodegradation, generate new substances, and change their original concentrations, but some will not. The former are called non-conservative substances and the latter are conservative substances. Therefore, when collecting emission data for each grid in the grid division result, the data corresponding to the m emission indicators contained in the emission data refer to the m conservative dynamically inert emission substances.

[0047] The water quality monitoring module is used to collect water quality data for each grid in the grid division result, and then summarize all the collected water quality data to obtain the water quality data set and transmit it to the classification module; referring to water quality indicators and standards, the quality of water can be judged by certain indicators, which mainly include: physical indicators such as temperature, chromaticity, turbidity, solid content, conductivity, etc.; chemical indicators such as pH value, hardness, dissolved oxygen concentration, chloride content, etc.; microbial indicators such as total bacteria count, total E. coli count, etc.; specifically refers to:

[0048] Step A1, according to the preset time window, collect corresponding data according to the water resource index for each grid in the grid division result, and obtain a water resource index data subset; such as temperature, chromaticity, turbidity and solid content, etc. In many cases, the lower the better for these indicators, for example, higher turbidity usually means more suspended matter in the water, which may affect the transparency and sensory quality of the water;

[0049] Step A2, according to the preset time window, collect the corresponding data of each grid in the grid division result according to the water environment index, and obtain the water environment index data subset; including pH value, hardness, dissolved oxygen concentration and chloride content, among which, pH value generally has a moderate range, and the pH value data type is classified into water quality classification set 2 in the following text, too high or too low is not ideal; too high hardness may cause scale deposition; and the higher the dissolved oxygen concentration, the better, because it indicates that there is enough oxygen in the water for biological use, and it is classified into water quality classification set 1; water with too high chloride content may not be suitable for drinking, and it is classified into water quality classification set 3;

[0050] Step A3: Collect corresponding data according to water ecological indicators for each grid in the grid division result according to the preset time window to obtain a subset of water ecological indicator data; such as total bacteria count and total E. coli count, the lower the better. High levels of bacteria or E. coli counts indicate that the water may be contaminated by feces, increasing the risk of disease transmission;

[0051] Step A4, summarizing the water resource index data subset, water environment index data subset, and water ecology index data subset in each grid to obtain a water quality index data subset;

[0052] Step A5: Aggregate all the water quality index data subsets in step A4 to obtain a water quality data set and transmit it to the classification module.

[0053] The classification module is used to classify the data types in the water quality data set according to the preset classification standards to obtain water quality classification set one, water quality classification set two and water quality classification set three, and then summarize the water quality classification set one, water quality classification set two and water quality classification set three to obtain a classified data set and transmit it to the comprehensive analysis module; specifically: the data types in the water quality data set are classified according to the preset classification standards to obtain Class I data, Class II data, and Class III data, Class I data indicates that the higher the data is, the better, Class II data indicates that the data is too high or too low, which is not ideal, and Class III data indicates that the lower the data is, the better; then all Class I data are summarized to obtain water quality classification set one, all Class II data are summarized to obtain water quality classification set two, and all Class III data are summarized to obtain water quality classification set three.

[0054] The comprehensive analysis module is used to analyze the water quality of the target grid obtained after division according to the classification data set, obtain the analysis value, and then obtain different types of analysis results according to the analysis value, and then summarize all the analysis values ​​into an analysis value set and transmit it to the display module; the specific logic is as follows:

[0055] Step 1: Mark each data in water quality classification set 1 as FL1i, and then substitute it into calculation formula 1 to obtain impact value 1: YX1 is the impact value 1, fi is the impact coefficient corresponding to each data FL1i in the water quality classification set 1 and fi is not zero, BL1i is the standard data value of a class corresponding to each data FL1i in the water quality classification set 1; the impact value 1 YX1 indicates the overall impact of all indicators on water quality, the higher the data, the better it is;

[0056] Step 2: Mark each data in the water quality classification set 2 as FL2i, and then substitute it into the calculation formula 2 to obtain the impact value 2: YX2 = ∑ (qi*FL2i) 2 , YX2 is the impact value 2, qi is the impact coefficient corresponding to each data FL2i in the water quality classification set 2, and qi is not zero; the impact value 2 YX2 represents the overall impact of all indicators on water quality that are too high or too low;

[0057] Step 3: Mark each data in water quality classification set 3 as FL2i, and then substitute it into calculation formula 3 to obtain impact value 3: YX3 is the third impact value, pi is the impact coefficient corresponding to each data FL3i in the third water quality classification set, and pi is not zero; the third impact value YX3 indicates the overall impact of all indicators on water quality, the lower the data, the better;

[0058] Step 4: Substitute the influence value 1 YX1, influence value 2 YX2, and influence value 3 YX3 into the analysis value calculation formula: y1, y2, y3 are all preset proportional values, and y1, y2, y3 are all greater than zero and the sum of y1, y2, y3 is one. y1, y2, y3 correspond to the influence value 1 YX1, influence value 2 YX2, influence value 3 YX3 on the water quality of the individual grid, i.e., the target grid obtained after division. X1, X2, X3 are the analysis thresholds corresponding to the influence value 1 YX1, influence value 2 YX2, influence value 3 YX3, respectively. FX is the analysis value.

[0059] Step 5. Compare the analysis value FX with the preset standard analysis value. When the analysis value FX is greater than or equal to the preset standard analysis value, the result of analysis type one is obtained. When the analysis value FX is less than the preset standard analysis value, the result of analysis type two is obtained. The larger the analysis value FX, the better the water quality. The smaller the analysis value FX, the worse the water quality. The analysis value FX can be used to show whether the water quality of the individual grid meets the requirements.

[0060] The evaluation module is used to calculate the emission value based on the emission data set, and then evaluate the emission value with the standard emission threshold to obtain the evaluation value. The evaluation results are summarized into an evaluation set and transmitted to the display module; specifically: first calculate the emission value: FZ is the emission value, hm is the proportionality coefficient corresponding to the emission data PFm, and then the ratio of the emission value FZ to the standard emission threshold is calculated. The standard emission threshold is established in the following way: for the sewage outlets within the target grid obtained after division, the sewage discharge permit of the enterprise corresponding to the sewage outlet is obtained. The sewage discharge permit stipulates the various environmental protection requirements that the sewage discharge unit must comply with when discharging sewage. These requirements include the location and number of sewage outlets, the discharge method, the discharge destination, the type of pollutants discharged, the emission concentration and emission amount, and the emission standards that must be implemented. Then, professionals determine the proportionality coefficient hm based on the degree of impact of the emission data PFm on the water quality, and determine the standard emission threshold of the target grid obtained after the division. Moreover, the sewage discharge permit of the enterprise is generally updated once a year. Therefore, when the sewage discharge permit of the enterprise is updated, the standard emission thresholds of the corresponding target grids obtained after division also need to be adjusted annually.

[0061] The sewage outlets in the target grid are sorted according to the size of the ratio. Each serial number corresponds to a preset evaluation value. For example, if there are n sewage outlets in the target grid, the emission values ​​of these n sewage outlets are calculated first, and then the ratio of the emission value FZ to the standard emission threshold is calculated. The sewage outlets in the target grid are sorted according to the size of the ratio. For example, after descending order, the preset evaluation value corresponding to the first sewage outlet is 100, and the evaluation value is reduced by 10 for each decrease in position. The preset evaluation value corresponding to the second sewage outlet is 90.

[0062] The display module is used to display the target water quality area in time and space according to the analysis value and evaluation set in the comprehensive analysis module and the preset display strategy; specifically: the water quality of the target water quality area at different times is displayed in chronological order, and a three-dimensional model of the target water quality area is established at the same time, and then the corresponding number is assigned to the individual grids after division according to the grid division result, and the corresponding position of the sewage outlet in the individual grid, that is, the target grid obtained after division, is displayed. The sewage outlet can also be numbered. When the analysis value FX is greater than or equal to the preset standard analysis value and the result of analysis type one is obtained, the water body of the individual grid is clear. When the analysis value FX is less than the preset standard analysis value and the result of analysis type two is obtained, the water body of the individual grid is turbid. , and when the water in the individual grid is turbid, the internal sewage outlets will display different colors in the graphics corresponding to the sewage outlets according to the level of the early warning signal. The more obvious the color is, the greater the impact of the sewage outlet on the water quality of the individual grid is, and a sewage investigation is needed. The relevant departments can conduct sewage outlet investigation operations; it can also be that the corresponding number assigned to the individual grid is used as the horizontal axis, its analysis value FX is used as the vertical axis, and the preset standard analysis value is used as the standard line, which can display in real time whether the individual grids in the target water quality area have water quality problems, or it can be that time is used as the horizontal axis, the analysis value FX of a specific individual grid is used as the vertical axis, and the preset standard analysis value is used as the standard line, which can display in real time whether the specific individual grid has water quality problems.

[0063] The grid division result refers to the grid division of the target water quality area according to the preset division standard to obtain multiple separate grids after division, and then the multiple separate grids after division are numbered in the space-time simulation module to obtain multiple continuously numbered grids, namely the grid division result. The purpose of division is to ensure that the water conditions of each grid are approximately consistent as much as possible, and the purpose of lot numbering is to better display the target water quality area in space and time in the display module. The following is a detailed description and example, and no further elaboration is required here.
