[0002] Phosphorus is an indispensable element for maintaining human and ecological health, and is also one of the limiting factors that cause eutrophication of water bodies. In recent years, with the rapid improvement of my country's industrial production level, phosphorus emissions from human production and life have increased, and the risk of phosphorus pollution in the basin has also increased accordingly.

[0003] In the existing management of phosphorus pollution in river basin environment, it is often limited to terminal pollution detection, and phosphorus detection is only carried out in the terminal watershed area of ​​the river basin. Although the degree of phosphorus pollution at that location can be known, the input, use and discharge of phosphorus-containing products often involve multiple complex links. Different industries are interconnected, forming a complex phosphorus flow network. It is difficult to track the industrial clusters associated with the river basin watershed area by relying solely on terminal monitoring methods, and it is impossible to assign responsibilities to each industry and closely monitor each industry. It is difficult to fundamentally solve the problem of phosphorus pollution in the river basin environment. Summary of the invention

[0042] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0045] like Figure 1 , Figure 2 As shown, the basin phosphorus statistics method according to the first aspect of the present invention includes:

[0046] S110, obtain the geographical location of the watershed and the distribution of industrial clusters associated with the watershed;

[0047] S120. Determine the boundaries of the river basin based on the geographical location of the river catchment area and the distribution of industrial clusters;

[0048] S130, divided into multiple phosphorus subsystems according to the industrial clusters in the basin;

[0049] S140, establishing a phosphorus flow model for each phosphorus subsystem according to the phosphorus flow relationship between the phosphorus subsystems;

[0050] S150. Analyze the phosphorus flow in the watershed based on the phosphorus flow model of each phosphorus subsystem.

[0051] The basin phosphorus statistics method of the present invention first determines the boundary of the basin according to the geographical location of the basin catchment area and the distribution of industrial clusters associated with the basin catchment area, so as to clarify the calculation of the subsequent phosphorus flow and facilitate the determination of the division of responsibilities. The industrial cluster situation in the basin is divided into multiple phosphorus subsystems, and the phosphorus flow model of each phosphorus subsystem is established for the phosphorus flow relationship of each phosphorus subsystem. The input and output of phosphorus in each phosphorus subsystem can be clearly known, so that the phosphorus flow of the basin can be analyzed. The design monitors the phosphorus emission flow relationship, which is convenient for implementing the emission reduction responsibility to each link of the industrial cluster, clarifying the phosphorus emission situation, and providing solid data guarantee for water ecological protection and environmental governance.

[0052] In some embodiments of the present invention, obtaining the distribution of industrial clusters associated with the watershed catchment area includes:

[0053] Obtaining the location of sewage treatment points, where sewage treatment points are factories and enterprises that centrally treat sewage and discharge it into a watershed catchment area;

[0054] Obtain the industrial zones in which the proportion of secondary industry in the industrial cluster is higher than the industrial proportion threshold and there are sewage treatment points within the distance threshold;

[0055] Determining the boundaries of the watershed according to the geographical location of the watershed catchment area and the distribution of industrial clusters includes: dividing the acquired industrial areas into the boundaries of the watershed.

[0056] It should be noted that this design first obtains the geographical location of the watershed catchment area, and then obtains the distribution of industrial clusters near the watershed catchment area and the distribution of industrial clusters that collect and treat sewage and discharge it into the watershed catchment area. Then, in step S120, these industrial clusters need to be confined within the boundaries of the watershed.

[0057] Among them, taking into account that sewage treatment points collect wastewater from nearby areas and then discharge it after treatment, causing the basin water body to be polluted by sources outside the basin catchment area, the sewage treatment points near the boundary of the catchment area are surveyed, the locations of the sewage treatment points are obtained, and the local leading industries are investigated. The level of industrial development affects to a certain extent the proportion of pollution sources outside the catchment area in the basin.

[0058] For industrial clusters where the proportion of secondary industry is higher than the industry proportion threshold, it proves that the proportion of industry (secondary industry) is relatively high, and the proportion of pollution collection and transfer will also be relatively high. In addition, combined with whether there is a sewage treatment point nearby, it can be known whether the sewage is discharged into the basin through the sewage treatment point. These industrial zoning also needs to be divided into the boundaries of the basin for pollution emission tracing analysis. Specifically, the industry proportion threshold and distance threshold are set according to actual needs.

[0059] In some embodiments of the present invention, the phosphorus subsystem also includes a phosphate mining and selection subsystem, a chemical production subsystem, an agricultural planting subsystem, a livestock and poultry breeding subsystem, an aquaculture subsystem, a food and feed processing subsystem, a sewage treatment subsystem, a solid waste treatment subsystem and a human consumption subsystem.

[0060] Each subsystem can have a phosphorus output and input relationship with one or more other subsystems. At the same time, it should be noted that these subsystems are all within the basin, and some subsystems also have phosphorus inflow and outflow relationships with industrial clusters outside the basin. By analyzing the phosphorus flow model of each subsystem, the flow of phosphorus can be clearly understood.

[0061] Each subsystem has products that need attention. Some subsystem product production processes and some subsystem product activities will have inflows and outflows of phosphorus.

[0062] For example, in some embodiments of the present invention, the types of products in the chemical production subsystem include one or more of phosphate fertilizer, compound fertilizer, chemical pesticides, synthetic detergents, soaps, plastics, chemical raw materials, Chinese patent medicines, pulp, cardboard, cloth, printed and dyed cloth, light leather, chemical fiber, synthetic rubber, crude steel, steel, coatings, chemical reagents, tap water, wooden furniture, artificial boards, sawn timber, and wood and bamboo floors.

[0063] Specifically, the following are the products that may exist in different subsystems:

[0064]

[0065]

[0066] In some embodiments of the present invention, taking a chemical production subsystem as an example, the phosphorus flow model of the chemical production subsystem includes a total phosphorus input and a total phosphorus output;

[0067] The phosphorus content of products produced in the chemical production subsystem is:

[0068] P i-production =Q i ×β i ;

[0069] Among them, i is the type of product, P i-production is the phosphorus content of the i-th product, Q i is the production volume of the i-th product, β i is the phosphorus content of the i-th product;

[0070] The phosphorus content of wastewater accompanying the product production process in the chemical production subsystem is:

[0071] P i-wastewater =Q i ×γ i-wastewater ×θ i-wasterwater ;

[0072] Among them, P i-wastewater is the phosphorus content of wastewater associated with the production process of the i-th product, γ i-eastewater is the wastewater generation coefficient for the production of the i-th product, θ i-wasterwater is the phosphorus content of wastewater produced by the production of the i-th product;

[0073] The phosphorus content of solid waste accompanying the product production process in the chemical production subsystem is:

[0074] P i-solidwaste =Q i ×γ i-solidwaste ×θ i-solidwaste ;

[0075] Among them, P i-solidwaste is the phosphorus content of solid waste associated with the production process of the i-th product, Qi is the output of the i-th product, γ i-solidwaste is the solid waste generation coefficient for producing the i-th product, θ i-solidwaste is the phosphorus content of solid waste produced by producing the i-th product;

[0076] The total phosphorus input and output are:

[0077]

[0078] Among them, P input is the total phosphorus input of the chemical production subsystem, P output is the total phosphorus output of the chemical production subsystem, is the total phosphorus content of n products produced in the chemical production subsystem, is the total phosphorus content of wastewater associated with the production of n products in the chemical production subsystem, is the total phosphorus content in solid waste associated with the production process of n products in the chemical production subsystem.

[0079] In some embodiments of the present invention, the phosphorus flow model of the chemical production subsystem includes the amount of imported phosphorus from outside the watershed to the chemical production subsystem. The amount of imported phosphorus from outside the watershed to the chemical production subsystem is:

[0080]

[0081] Among them, P materialsimport is the amount of phosphorus imported from outside the basin by the chemical production subsystem, j is the type of production raw materials, The total phosphorus content of n production raw materials input into the chemical production subsystem from other subsystems in the basin.

[0082] It can be understood that the total phosphorus input of a subsystem minus the total phosphorus content in various production raw materials flowing into other subsystems in the basin is the amount of imported phosphorus into the subsystem from outside the basin.

[0083] In some embodiments of the present invention, the phosphorus flow model of the chemical production subsystem includes the export phosphorus amount of the chemical production subsystem to the outside of the basin, and the export phosphorus amount of the chemical production subsystem to the outside of the basin is:

[0084]

[0085] Among them, i is the type of product, P productionexport is the amount of exported phosphorus from the chemical production subsystem to the outside of the basin, P localusage It is the usage of products produced by the chemical production subsystem in the basin.

[0086] It is understandable that after the total phosphorus content of various products produced in the subsystem, part of the products will be used by other subsystems in the basin, and the remaining part, that is, the total phosphorus content of various products produced in the subsystem minus the usage of products produced by the subsystem in the basin, is the export phosphorus output by the subsystem outside the basin.

[0087] The statistical system according to the second aspect of the present invention is used to execute the watershed phosphorus statistical method disclosed in any of the above embodiments, such as Figure 1 , 2As shown, it includes: an acquisition module 200, which is used to obtain the geographical location of the watershed catchment area and the distribution of industrial clusters associated with the watershed catchment area; a boundary determination module 300, which is used to determine the boundary of the watershed according to the geographical location of the watershed catchment area and the distribution of industrial clusters; a division module 400, which is used to divide the watershed into multiple phosphorus subsystems according to the industrial clusters in the watershed; a processing module 500, which is used to establish a phosphorus flow model for each phosphorus subsystem according to the phosphorus flow relationship between the phosphorus subsystems; and an analysis module 600, which is used to analyze the phosphorus flow amount of the watershed according to the phosphorus flow model of each phosphorus subsystem.

[0088] The statistical system of the present invention applies the watershed phosphorus statistical method disclosed in any of the above embodiments to monitor the flow relationship of phosphorus emissions, facilitate the implementation of emission reduction responsibilities in all links of the industrial cluster, clarify the phosphorus emission situation, and provide solid data support for water ecological protection and environmental governance.

[0089] The data used for phosphorus flow statistics can be divided into activity level data and accounting parameters. The activity level data of agricultural planting, livestock and poultry breeding, aquaculture and fishing, industrial production, waste treatment, etc. in the basin have been collected and sorted out over the years. The sources are municipal statistical yearbooks, provincial statistical yearbooks, and national statistical yearbooks. The municipal statistical yearbook data are given priority. The accounting parameters are used to estimate the phosphorus flow of various activities. In addition to collecting parameters from books and materials as much as possible, the accounting parameters can be obtained by consulting a large number of empirical research literature.

[0090] This design is based on the material flow analysis method to monitor the phosphorus flow model, combined with the actual industrial situation in the basin, to achieve a more comprehensive basin demarcation. It can fully identify the production activities closely related to phosphorus emissions in the industrial subsystem, clarify the contribution of different production processes to phosphorus emissions, and comprehensively sort out the main sources of phosphorus emissions, thereby providing a scientific basis for more accurate pollution control and management.
