[0002] In recent years, to support the river chief system's water pollution prevention and control tasks, many regions have required calculations of the increased pollution load reduction for newly constructed urban stormwater and sewage separation projects. These calculations primarily focus on common pollutant indicators such as chemical oxygen demand (COD), ammonia nitrogen, total nitrogen, and total phosphorus. Traditional methods for calculating engineering pollution load reduction include comparing water quality and quantity data from sewage treatment plants, and calculating urban non-point source pollution loads based on initial runoff pollution reduction.

[0003] Currently, traditional methods for calculating pollution load reduction in engineering projects include comparing water quality and quantity data from wastewater treatment plants, and calculating urban non-point source pollution load based on initial runoff pollution reduction. However, if a wastewater treatment plant is not specifically designated for a particular stormwater and wastewater separation project, its pollution load reduction cannot be allocated to that area. Therefore, these methods have limitations in calculating the increased pollution load reduction for urban stormwater and wastewater separation projects, leading to inaccurate results and consequently affecting subsequent projects. Summary of the Invention

[0068] like Figure 1 As shown, this embodiment provides an example of a method for estimating the increase or decrease in pollution load. In this embodiment, the increase or decrease in pollution load is based on the diversion and renovation project of a preset area. The method for estimating the increase or decrease in pollution load includes the following steps:

[0069] Step S1: Obtain the layout before and after the modification of the preset area, and generate the finite element model before and after the modification based on the point cloud data of the preset area.

[0070] Step S2: Obtain several rainfall data points for a preset area based on a preset natural time period.

[0071] Preferably, the preset natural duration period can be set to a natural hour, a natural day, a natural week, a natural month, a natural year, or other units of natural duration; rainfall data can be obtained directly from the meteorological bureau, which is easy to obtain.

[0072] Step S3: Based on all rainfall data, use preset software to simulate the precipitation data of the finite element model before and after the modification to obtain the effective load before and after the modification.

[0073] Step S4: Obtain the first difference between the effective load after the modification and the effective load before the modification.

[0074] Step S5: Assign a pollution emission coefficient to the first difference according to a preset strategy.

[0075] Step S6: Obtain the comprehensive runoff coefficient and pollutant concentration of the preset area.

[0076] Step S7: Calculate the increase or decrease in pollution load in the preset area based on the pollution emission coefficient, comprehensive runoff coefficient, and pollutant concentration using a preset algorithm.

[0077] Furthermore, step S1 specifically includes the following steps:

[0078] Step S11: Obtain the design report for the preset area.

[0079] Step S12: Generate first point cloud data based on a preset area from the design report using preset software.

[0080] Step S13: Obtain the elevation information of the preset area and output the elevation information to the first point cloud data to obtain the finite element model before the modification based on the preset area.

[0081] Step S14: Obtain the renovation report for the preset area.

[0082] Step S15: The modification report is used to generate second point cloud data based on a preset area using preset software.

[0083] Step S16: Output the elevation information as the second point cloud data to obtain the modified finite element model based on the preset area.

[0084] Preferably, the layout before and after the renovation can be determined by collecting the construction drawings and reports of the preset area (such as residential areas, urban areas, factories, etc., areas with drainage pipe networks), as well as the design reports (preliminary design reports or construction design reports) of the rainwater and sewage separation renovation project. All of the aforementioned reports are complete and easily accessible in practical applications.

[0085] Furthermore, step S3 specifically includes the following steps:

[0086] Step S31: Assign a preset unit precipitation amount to the finite element model before the modification, and obtain the first total precipitation amount when the finite element model before the modification starts to drain.

[0087] Step S32: Obtain the first surplus of the first total precipitation at preset intervals.

[0088] Step S33: Determine whether the first surplus is less than or equal to the preset threshold.

[0089] Step S34: If the first margin is less than or equal to the preset threshold, then obtain the second difference between the first total precipitation and the first margin, and define the second difference as the effective load before the modification.

[0090] Step S35: Assign a preset unit precipitation amount to the modified three-dimensional finite element model and obtain the second total precipitation amount when the modified three-dimensional finite element model starts to drain water.

[0091] Step S36: Obtain the second surplus of the second total precipitation at preset intervals.

[0092] Step S37: Determine whether the second surplus is less than or equal to the preset threshold.

[0093] Step S38: If the second margin is less than or equal to the preset threshold, then obtain the third difference between the second total precipitation and the second margin, and define the third difference as the effective load after the modification.

[0094] Preferably, the effective load before and after the renovation are the reduction of the self-rainfall load of the preset area before and after the renovation, respectively, in millimeters. It can be understood as the pollution load that the drainage network of the preset area can accommodate or quickly handle, which can be marked as R0. Rainfall less than R0 can currently be fully treated by the sewage treatment plant and does not generate pollution load.

[0095] Preferably, R0 can be 10 mm. Based on existing technical parameters and the sewage treatment situation in various types of areas, 10 mm is deducted (that is, it is assumed that rainfall less than 10 mm can be fully treated by sewage treatment plants and will not generate pollution load).

[0096] Furthermore, step S5 specifically includes the following steps:

[0097] Step S51: Obtain the pre-modification drainage system assembly from the finite element model.

[0098] Step S52: Obtain the sewage riser layout and rainwater riser layout of the drainage system assembly before the renovation.

[0099] Step S53: Obtain the intersection of the sewage riser layout and the rainwater riser layout.

[0100] Step S54: Obtain the merging length and diverging length of the drainage system assembly before the modification based on the confluence.

[0101] Step S55: Define the pollution emission coefficient based on the ratio of the diversion length to the merging length.

[0102] Furthermore, step S55 specifically includes the following steps:

[0103] Step S551: When the ratio is 0, assign a first pollution emission coefficient.

[0104] Step S552: When the ratio value is within the first preset range, assign a second pollution emission coefficient.

[0105] Step S553: ​​When the ratio value is within the second preset range, assign a third pollution emission coefficient.

[0106] Preferably, the pollution emission coefficient can be divided into 3 to 5 levels based on the pre-designed area's rainwater and sewage separation status before the renovation, and a pollution emission coefficient is assigned to each level, as shown in Table 1. The higher the coefficient, the greater the comparison before and after the renovation, and the greater the reduction benefit of the new pollution load generated after the renovation.

[0107]

[0108] Table 1

[0109] Preferably, in this embodiment, the pollution emission coefficient is based on the average renovation investment of the three types of communities, which is taken as 1; the average renovation investment per unit area of ​​the three types of communities is taken as 1; the average renovation investment per unit area of ​​the three types of communities is taken as the ratio of the average renovation investment per unit area of ​​the three types of communities, which is 0.19, 0.32, and 1 respectively (because the average renovation investment per unit area of ​​the two types of communities is more than that of the three types of communities in this example, it is taken as 1).

[0110] Furthermore, step S6 specifically includes the following steps:

[0111] Step S61: Obtain the proportion of runoff generated by effective rainfall according to the preset outdoor drainage design standard, and define the runoff proportion as the comprehensive runoff coefficient.

[0112] Step S62: Obtain the water quality monitoring report of the layout before the modification, and obtain the pollutant concentration in the water quality monitoring report.

[0113] Preferably, the comprehensive runoff coefficient can be set with reference to the outdoor drainage design standard, please refer to Table 2:

[0114] densely built urban areas 0.60～0.70 Urban building dense area 0.45～0.60 Sparsely built urban areas 0.20～0.45

[0115] Table 2

[0116] Furthermore, step S7 specifically includes the following steps:

[0117] Step S71, calculate the increase or decrease in pollution load according to equation (1):

[0118] fh=H·ΔF·a·q·c·10 -9 (1).

[0119] Where fh is the amount of pollution load reduction, H is the average annual precipitation of the preset area, ΔF is the first difference, a is the comprehensive runoff coefficient, q is the pollution emission coefficient, and c is the pollutant concentration.

[0120] This embodiment obtains the pre-renovation and post-renovation layouts of a preset area, and generates pre-renovation and post-renovation finite element models based on the point cloud data of the preset area. It then simulates rainfall data for each of the two finite element models based on several rainfall data points over a preset natural duration period, obtaining the pre-renovation and post-renovation effective loads. A pollution emission coefficient is assigned to the first difference between the post-renovation and pre-renovation effective loads. Finally, the increase or decrease in pollution load is calculated using the pollution emission coefficient, comprehensive runoff coefficient, and pollutant concentration. This application addresses the shortcomings of current urban stormwater and sewage separation renovation projects, such as complexity, difficulty in data collection, and cumbersome pollution load calculations. It proposes a method for estimating the increase or decrease in pollution load in urban stormwater and sewage separation renovation projects.
