[0080] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0081] Embodiment 1:

[0082] A method for calculating the pollution load contribution amount, where the pollution load contribution amount is based on the rain and sewage diversion transformation and the renovation and improvement project of the old drainage pipe network of the regional plot drainage unit. The method for calculating the pollution load contribution amount includes:

[0083] Obtain the pre-transformation discharge pollution load amount and the set post-transformation discharge pollution load amount of the region, and generate the pre-transformation measured data model C a ={C a (k)}=(C 1 , C 2 , ···, C n ) and the post-transformation expected data model C b ={C b (k)}=(C 11 , C 22 , ···, C nn );

[0084] The pre-transformation measured data model C a is established based on several sewage discharge water quality data of different plot drainage units in the obtained region;

[0085] The post-transformation expected data model C b is established based on the expected sewage discharge water quality data C b , the permanent population number N and the daily water consumption Q of different regions of the plot after transformation;

[0086] The pre-transformation discharge pollution load amount of the region is established by multiplying the pre-transformation measured data model, the permanent population number and the daily water consumption of different plot drainage units in the region through a preset software, that is, C a N a Q;

[0087] The post-transformation discharge pollution load amount of the region is established by multiplying the post-transformation expected data model, the permanent population number and the daily water consumption of different plot drainage units in the region through a preset software, that is, C b N b Q;

[0088] Obtain the pollution load contribution amount M of different plot drainage units in the region k Based on the post-transformation discharge pollution load amount M of the region b = Q=(C 11 N 11 Q+C22 N 22 Q + · · · + C nn N nn The pre - renovation pollution load Q of the area and the pre - renovation pollution load M of the area a = =(C 1 N 1 Q + C 2 N 2 Q + · · · + C n N n Q), that is, M k ={M b - M a}.

[0089] The present invention is further optimized. By establishing a sequence identification according to the pollution load contribution amount of the drainage units of different plots in the area, a unified database of Three Gorges Cloud is established for accurately and quickly selecting the best drainage units of the area plots for renovation in the next step.

[0090] According to the overall goal of improving the expected sewage collection efficiency, based on the above - mentioned calculation method of the pollution load contribution amount, the method for further selecting the optimal area plot drainage unit for renovation includes:[[]]

[0091] Based on the influent water volume data of the sewage treatment plant in the area, the pollution load amounts of the expected influent water quality data after renovation and the influent water quality data before renovation are calculated respectively through preset software, and the total pollution loads M a and M b ;

[0092] Obtain the expected additional target amount of regional pollution load △M as the target value M of sewage collection efficiency improvement 1 and the total current regional drainage pollution load M a The difference, M 1 Based on the average sewage concentration C bk and the influent water volume Q 总 of the sewage treatment plant, it is established by multiplying the data, that is, M 1 = C bk Q 总 , △M = M 1 - M a ;

[0093] The total pollution load contribution of the regional plot drainage unit △M k is established by accumulating the pollution load contribution amounts of different plot drainage units in the area, that is, △M k = ;

[0094] When the total pollution load contribution of the regional plot drainage unit △Mk When the additional target amount ΔM of the regional pollution load is less than the expected value, further adjust the expected sewage discharge water quality data of the drainage unit after transformation until the total contribution amount ΔM of the pollution load of the regional plot drainage unit k until it is greater than the additional target amount ΔM of the regional pollution load expected.

[0095] When the total contribution amount ΔM of the pollution load of the regional plot drainage unit k is greater than the additional target amount ΔM of the regional pollution load expected, in the order of the contribution amounts of the pollution loads of the drainage units of different plots in the region from small to large, the marked plot drainage units with relatively low contribution amounts of the pollution load are gradually screened out from the unified database of the Three Gorges Cloud through the preset software until the total contribution amount ΔM of the pollution load of the regional plot drainage unit k until it is slightly greater than or equal to the additional target amount ΔM of the regional pollution load expected;

[0096] After screening and excluding the plot drainage units with relatively low contribution amounts of the pollution load M k ranked at the end by the preset software, there is no need to carry out the later rain - sewage diversion transformation and the repair and improvement project of the drainage pipeline network, saving a large amount of investment in funds, manpower and materials, thus realizing an implementation technical method with the best production - investment ratio for accurately, quickly and efficiently improving the collection efficiency of the sewage system.

[0097] Embodiment 2:

[0098] As Figure 1 shown, this embodiment provides an example of using the measurement method of the pollution load contribution amount to improve the sewage collection efficiency of a sewage treatment plant's receiving area in a certain city. In this embodiment, the pollution load contribution amount is based on the rain - sewage diversion transformation and the repair and improvement project of the old drainage pipeline network of the regional plot drainage unit. The measurement method of the pollution load contribution amount includes the following steps:

[0099] Step W1: According to the sewage receiving range of a sewage treatment plant, divide different regional drainage units, and detect (or monitor) the sewage concentration at the outlet of the sewage pipe or combined sewer of the drainage unit. The water quality detection (or monitoring) indicators include at least CODcr or BOD 5 one of them, at 3 times in the early, middle and late periods or continuously for 24 hours, and the frequency is 3 consecutive days on sunny days and 2 consecutive days on rainy days. The background concentration of each drainage unit in different regions takes the arithmetic mean. The measured sewage concentration before the transformation of the drainage unit is C a ={C a (k)}=(215, 123, ···, 95), and set the expected sewage concentration after the transformation of the drainage unit as C b ={C b(k)} = (300, 260, ···, 200). The expected additional target amount of regional pollution load ΔM is the target value M for improving the sewage collection efficiency 1 and the total current regional drainage pollution load M a The difference is ΔM = M 1 - M a . Where M 1 = C 0 Q 厂 , C 0 is the target concentration of the influent to the renovated sewage treatment plant, 260 mg / L, and Q 厂 is the influent flow rate of the renovated sewage treatment plant, 160,000 m 3 / d, that is, M 1 = 41.60 t / d.

[0100] Step W2: Investigate and collect the permanent population numbers N of different regional drainage units within the sewage collection range of the sewage treatment plant, approximately 800,000 people = {N a (k)} = (215, 123, ···, 95), and estimate the average daily water consumption Q of the urban area population as 200 L / d by collecting the water sales data of the local water supply company.

[0101] Step W3: Based on the measured sewage concentration C a = (215, 123, ···, 95) before the renovation of the drainage unit, the expected sewage concentration C b = (300, 260, ···, 200) after the renovation, the permanent population number N of approximately 800,000 people, and the average daily water consumption Q of the urban area population as 200 L / d, establish the measured data model before the renovation of the drainage unit as C a (k)N a (k)Q, and the expected data model after the renovation of the drainage unit as C b (k)N b (k)Q.

[0102] Step W4: Through the measured data models before and after the renovation of the drainage unit, calculate the discharged pollution load before the renovation of the drainage unit as M a ={C a (k)N a (k)Q} = (C 1 N 1 Q, C 2 N 2 Q, ···, C n N n Q) = 23.84 t / d, and the discharged pollution load after the renovation of the drainage unit is M b = Q = (C 11 N 11 Q + C22 N 22 Q+· · ·+C nn N nn Q) = 41.80t / d. Through the above data model and MIKE software, the pollution load after the transformation of the regional drainage unit is calculated, and a quantitative dynamic simulation analysis chart between the total pollution load and time before and after the transformation of the regional drainage unit is established, such as Figure 4 and 5 :

[0103] Step W5: Using the calculated value M a 、M b , calculate the pollution load contribution M of each drainage unit in the area after transformation k ={M b -M a}={(C 11 N 11 QC 1 N 1 Q)+(C 22 N 22 QC 2 N 2 Q)+· · · +(C nn N nn QC n N n Q)}={0.05+0.04+· ·· +0.07}, and establish a model in which the contribution of pollution load is sorted from large to small.

[0104] Step W6: Through the data model before and after the drainage unit transformation, the total amount of pollution load before the drainage unit transformation can be calculated as △M k = =17.96t / d.

[0105] Step W7: If the pollution load of the drainage unit in the regional plot can contribute to the total amount △M k When the pollution load is less than the expected additional target amount △M of the regional pollution load, return to step 1, adjust the expected sewage concentration value after the drainage unit transformation, and then recalculate the model. In this embodiment, the pollution load of the drainage unit in the regional plot can contribute to the total amount △M k =17.96t / d is greater than the expected additional target amount of regional pollution load △M=41.60-23.84=17.76t / d, so proceed to the next step.

[0106] Step W8: Select the optimal value of the total contribution (i.e. △M) through the data model k ≈△M), that is, △M k≈17.76 t / d. According to the order of the pollution load contribution amount from large to small, the drainage units with relatively small contribution amounts in the regional plots are screened out, and the cumulative contribution amount is approximately 17.96 - 17.76 = 0.20 t / d. According to the above method, 15 drainage units are screened out.

[0107]

[0108] Step W9: According to the results of the program in Step W8, for the drainage units with relatively small contribution amounts screened out, generate a list of drainage units that do not need to be renovated temporarily (see the above table), and include the other marked drainage units in the regional plots in the list of drainage units in the plots that need to be renovated.

[0109] Through the implementation of Steps W1 - W9, the drainage units of plots with relatively small pollution load contribution amounts that do not require the renovation and repair of the drainage pipe network can be accurately, quickly, and efficiently screened out, saving a large amount of government investment in funds, manpower, and material resources, improving the input-output ratio, conforming to the current high-quality development direction of enhancing the efficiency of urban sewage collection, and having significant social, environmental, and technical and economic benefits.

The functions of each module in the device and the achieved technical effects correspond to the functions and achieved technical effects of the pollution load contributable quantity method in the above embodiments respectively, and will not be elaborated here.

[0121] Such as Figure 3 is a terminal electronic device corresponding to the embodiment of the present invention for precisely calculating the model. The terminal electronic device includes: computer devices composed of facilities such as a database, a memory, model software, and a processor capable of running and processing data. When the processor executes the computer module, it implements the steps in the embodiment of the above pollution load contributable quantity method. Or, when the processor executes the computer module, it implements the functions of each module in the embodiment of the device for precisely improving the collection efficiency based on the pollution load contributable quantity.

[0122] The terminal electronic device can be various computing devices such as a desktop computer, notebook, palmtop computer, tablet computer, supercomputer, network computer, biological computer, photonic computer, quantum computer, and cloud server. The terminal electronic device may include, but is not limited to, devices such as a database, a memory, model software, a processor, etc. Those skilled in the art can understand that the schematic diagram is only an example of the terminal device, and does not constitute a limitation on the terminal device. It may include more or fewer components than shown in the figure, or combine certain components, or different components. For example, the terminal electronic device may also include a cache memory, input / output devices, network access devices, a control bus, ports, etc.

[0123] The database is a repository for storing data such as the background monitoring before the transformation of the drainage unit and the setting of expected goals. It is an organized, shared, and uniformly managed data set that is stored in a computer for a long time.

[0124] The memory is a collection of many storage units arranged in order of unit number. It is a memory component used to store programs, or modules and various data information. It can be divided into two categories: main memory (internal memory) and auxiliary memory (external memory). The one that directly exchanges information is the main memory. The internal memory is frequently used by the computer during program execution and is directly accessible during an instruction cycle. The external memory requires the computer to read information from an external storage device such as a magnetic tape or a disk. The central processing unit realizes various functions of the terminal device by running or executing computer programs, or modules stored in the memory, and by calling data stored in the memory. The internal storage is directly connected to the CPU and is composed of electronic components with relatively fast access speeds, but the storage capacity is small. The memory is generally divided into random access memory (RAM), read-only memory (ROM), and flash memory (Flash Memory). Commonly used memory includes memory sticks. The external storage is an extension of the internal storage. It usually has a large storage capacity and a low price, but a slow storage speed. It is generally used to store a large number of programs that are not used temporarily. It can only exchange information with the memory and cannot be directly accessed by other components of the computer system. Commonly used external storage includes disks, magnetic tapes, optical discs, hard disks, etc.

[0125] The model software is software for dynamic analysis of modeling such as simulating water volume, water quality, and pollutant diffusion, including self-programming software, SWMM, MIKE and other dynamic model quantification software. The model software is respectively applied to the data model module, the pollution load module, the contribution amount and ranking module, the total contribution amount module, the target amount module, the optimal value model module, and the drainage unit list module to achieve different functional requirements. SWMM is a dynamic precipitation-runoff simulation model, mainly used for simulating a single precipitation event in a city or long-term water volume and water quality simulation. This hydraulic model is used to simulate the flow of runoff and external water in pipelines, channels, storage and treatment units, etc. in the drainage pipeline, and the water quality model is used to simulate the water pollution load generated during the process of runoff generation and concentration. The MIKE model simulates the transport process of dissolved substances in water due to convection and diffusion, constructs a hydrodynamic and water quality quantification simulation analysis of the urban sewage collection system, and quantitatively evaluates the reachability of the total target of the pollution load contribution amount.

[0126] As the operation and control core of the terminal electronic device system, the processor is the final execution unit for information processing and program operation. Its main function is to interpret computer instructions and process data in computer software. The processor can be a central processing unit (CPU), which mainly includes two parts, namely a controller and an arithmetic unit. Its main functions are to process instructions, execute operations, control time, and process data. In the architecture of the terminal electronic device, the CPU is the core hardware unit that controls and allocates all hardware resources (such as memory, input and output units) of the computer and executes general operations. The CPU is the operation and control core of the computer. All operations at the software layer in the computer system will ultimately be mapped to the operations of the CPU through the instruction set.

[0127] It should be noted that the device embodiments described above are only illustrative. The implementation steps W1~W9 therein cannot be separated independently, and the order is irreversible; the functional modules G1~G9 need to be all applied to achieve the purpose of the solution of this embodiment.

[0128] The embodiment of the present invention also provides a computer-readable storage medium, which includes a stored computer program. When the computer program runs, it controls the device where the computer-readable storage medium is located to execute the method for improving the precise collection efficiency of the pollution load contribution amount as described in the above embodiment.
