[0002] With the acceleration of urbanization, the amount of urban sewage discharge continues to increase, and the requirements for sewage treatment and collection systems are becoming higher and higher. Plant-network integration has become an important development trend of sewage collection systems.

At the same time, plant-network integration can also help to achieve supervision and control of the entire process of sewage collection, treatment and discharge.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0078] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0079] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present invention and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

[0080] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0081] First, the terms involved in this application are explained.

[0082] BOD5: Biological Oxygen Demand, five-day biochemical oxygen demand, the amount of free oxygen consumed by aerobic microorganisms to oxidize and decompose organic matter per unit volume of water within 5 days, is an important indicator of the degree of organic pollution in water.

[0083] With the acceleration of urbanization, the amount of urban sewage discharge continues to increase, and the requirements for sewage collection and treatment systems are becoming higher and higher. Plant-network integration has become an important development trend of sewage collection systems. By unifying the construction and operation of drainage networks and sewage treatment plants, resource allocation can be optimized and the overall efficiency of urban drainage systems can be improved. At the same time, plant-network integration can also help to achieve supervision and control of the entire process of sewage collection, treatment and discharge.

[0084] While promoting the integrated construction and operation of the plant and network, the payment mechanism based on the environmental governance effect is also crucial. At present, the payment mechanism of the traditional municipal sewage treatment PPP project is mainly based on engineering payment. The sewage collection and treatment system has not established a reasonable environmental governance effect management orientation, and the capital investment is out of touch with the pollution reduction effect, resulting in a waste of capital resources and poor governance effect; and the sewage pipe network and sewage treatment plant are operated independently, and there is a contradiction in the assessment of payment under the situation of plant and network separation.

[0085] The method for calculating sewage collection and treatment service indicators based on environmental effects provided in this application is intended to solve the above technical problems of the prior art.

[0086] First, the implementation scenarios involved in this application are described.

[0087] Figure 1 This is a diagram of the implementation scenario of the method for calculating the sewage collection and treatment service index based on environmental effects provided in this application. Figure 1 As shown, the process of calculating the urban drainage system index involves: a server 101 where a central control system having an operation index calculation module and a green economy module is located, an edge server group 102 where drainage network control systems in different areas are located, and a sewage treatment plant 103, and the edge server group 102 is respectively provided with a sewage collection module, and the sewage treatment plant 103 is provided with a sewage treatment module; the server 101 is respectively communicated with the edge server group 102 and the sewage treatment plant 103, and the server 101 receives the relevant data information of sewage collection obtained by the sewage collection module in the edge server group 102, and can also receive the relevant data information of sewage treatment obtained by the sewage treatment module in the sewage treatment plant 103.

[0088] It can be understood that there are multiple operation modules in the urban drainage system, including: operation index calculation module, sewage collection module, sewage treatment module and green economy module; among them, the operation index calculation module is used to calculate the comprehensive effects of sewage collection service, sewage treatment service, resource utilization of sewage treatment products and energy saving and carbon reduction of sewage treatment plants in the actual operation of the current urban drainage system; the sewage collection module is used to determine the actual effect of sewage collection of the urban drainage system, and convert it into relevant data and send it to the operation index calculation module; the sewage treatment module is used to determine the actual effect of the urban drainage system on pollutant reduction, and convert it into relevant data and send it to the operation index calculation module; the green economy module is used to determine the actual effect of the urban drainage system in resource utilization of sewage treatment products and energy saving and carbon reduction in sewage treatment plant operation; specifically, the operation index calculation module obtains the performance data of the sewage collection module, sewage treatment module and green economy module; based on the indicator information obtained by the operation index calculation module, the urban drainage system can dynamically adjust the relevant parameters of sewage centralized collection efficiency, sewage treatment and operation effect of sewage treatment plants.

[0089] For example, the operation indicator calculation module obtains the performance data of the sewage collection module, the sewage treatment module and the green economy module, and determines the indicator information of the current urban drainage system in environmental governance based on the performance data, and obtains the actual impact of the rebuilt urban drainage system on the environment; if the indicator information indicates that the current sewage treatment has an impact on the environment, that is, it has been significantly improved compared to before the reconstruction, then the server 101 can send information to maintain the current operating status to the edge server group 102 and the sewage treatment plant 103; if the indicator information indicates that the current sewage treatment has an impact on the environment Constraints, that is, there is no significant improvement or adverse impact compared to before the reconstruction, then the server 101 can send information to improve the current operating conditions to the edge server group 102 and the sewage treatment plant 103, and reasonably manage and improve the sewage collection and treatment work according to the sewage collection situation and the operating capacity of the sewage treatment plant. Specifically, for the drainage network, the maintenance and maintenance of supporting facilities such as inspection wells and lifting pump stations can be strengthened, and leakage points and mixed connections can be repaired in time to ensure their normal operation; for the sewage treatment plant, the aeration volume, chemical addition, etc. can be adjusted to optimize the biological treatment effect.

[0090] The present application provides a method for calculating sewage collection and treatment service indicators based on environmental effects, by obtaining the pollutant collection effectiveness data of the sewage network of the urban drainage system, the pollutant reduction effectiveness data of the sewage system, and the relevant effectiveness data of sludge resource utilization, recycled water resource utilization, and energy conservation and carbon reduction, and using the actual effect calculation logic of pollutant equivalents, the obtained multiple effectiveness data are calculated and processed to determine the actual indicators of the contribution of the urban drainage system to the environment, and based on the actual indicators, the sewage service efficiency of the sewage network and sewage treatment plant, as well as the resource optimization utilization rate, energy consumption, etc. are dynamically adjusted. This method improves the overall operational efficiency of the urban drainage system plant and network integration, and based on multiple effectiveness data, more targetedly encourages the improvement of the core governance effect of the water environment, as well as resource utilization and energy-saving performance in different aspects, improves the efficiency of sewage collection and treatment and resource utilization, promotes pollution reduction and carbon reduction, and improves the overall effect of water environment governance.

[0091] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0092] Figure 2 Schematic diagram of the process of calculating the sewage collection and treatment service index based on environmental effects provided in the embodiment of the present application Figure 1 The execution subject of this embodiment may be, for example, an urban drainage system provided with an operation index calculation module. Figure 2 As shown, the method for calculating the sewage collection and treatment service index based on environmental effects provided in this embodiment includes:

[0093] S201: Obtain environmental management effectiveness data of urban drainage systems.

[0094] Among them, environmental governance effectiveness data include sewage collection effectiveness data, pollutant reduction effectiveness data, and green economic parameters.

[0095] The environmental governance effectiveness data are collected by the sewage collection module, sewage treatment module and green economy module; the sewage collection effectiveness data and pollutant reduction effectiveness data can intuitively reflect the actual effect of the urban drainage system in sewage treatment, and the green economy parameters reflect the resources that can be reused after sewage treatment and the energy-saving and carbon-reduction efficiency of the urban drainage system.

[0096] Environmental governance effectiveness data refers to the relevant data information stored in the urban drainage system on the sewage collection service, sewage treatment service and resource utilization service provided by the drainage system, and the environmental governance effectiveness data can be used to determine the effect of the urban drainage system in improving the environment.

[0097] For example, environmental governance effectiveness data include sewage collection effectiveness data, pollutant reduction effectiveness data, and green economic parameters, among which sewage collection effectiveness data can be determined through the flow meter data of the drainage network obtained by the sewage collection module, specifically including: the amount of sewage collected, sewage collection coverage, and pollutant concentration; pollutant reduction effectiveness data can be determined through the monitoring report of the sewage treatment plant obtained by the sewage treatment module, specifically including: the change in pollutant concentration in the treated sewage and the total pollutant reduction; green economic parameters can be determined through the ecological environment monitoring report and sewage plant operation monitoring report obtained by the sewage treatment module, specifically including: tail water reuse volume, sludge resource utilization rate, sewage plant energy consumption, etc. This application does not impose special restrictions on the data types obtained by different operating modules in the urban drainage system.

[0098] S202: Determine environmental governance indicators and additional incentive indicators based on sewage collection performance data, pollutant reduction performance data and green economic parameters.

[0099] Among them, environmental governance indicators are used to indicate the effectiveness of urban drainage systems in sewage collection and pollutant reduction, and additional incentive indicators are used to reflect the additional effectiveness of urban drainage systems in resource utilization and energy conservation and carbon reduction.

[0100] It is understandable that the actual results of sewage collection and treatment include: positive results and negative results; among them, positive results mean that the sewage services provided are more effective in collecting and treating sewage, while negative results mean that the sewage services provided are less effective in collecting and treating sewage.

[0101] When measuring the effectiveness of the urban drainage system in environmental governance, the sewage collection service of the drainage network and the sewage treatment service of the sewage treatment plant are both used as measurement indicators of the urban drainage system in environmental governance; in addition, the indirect impact of the urban drainage system on the city's environment after using the sewage service can also be used, that is, the additional incentive indicator; when determining the environmental governance indicators and additional incentive indicators, the changes in the effectiveness data before and after the reconstruction of the urban drainage system are compared to determine the changes in the effectiveness data before and after the reconstruction of the urban drainage system; specifically, when comparing the effectiveness data, the annual average effectiveness indicators of the urban drainage system before reconstruction and the annual average effectiveness indicators of the urban drainage system after reconstruction can be used.

[0102] Based on the sewage collection effectiveness data and pollutant reduction effectiveness data, the sewage collection and sewage treatment efficiency of the urban drainage system during the sewage collection and treatment process is determined, and the obtained efficiency data information is processed in a indicator manner to obtain environmental governance indicators; based on the green economic parameters, the indirect benefits produced by the urban drainage system after sewage treatment are determined, and the indirect benefits data are processed in an indicator manner to obtain additional incentive indicators.

[0103] For example, the operation indicator calculation module in the urban drainage system can quantify the actual environmental governance effect of the sewage network and the sewage treatment plant in the form of pollutant equivalents when determining the environmental governance indicators, that is, the sewage collection effect of the drainage network and the overall reduction effect of the drainage system composed of the drainage network and the sewage treatment plant are evenly distributed, and then the corresponding environmental governance indicators can be obtained; when determining the additional incentive indicators, the green economic parameters can be obtained according to the green economic module, that is, the reuse rate of sludge and recycled water related to sewage treatment in the urban drainage system and the energy-saving and carbon-reduction efficiency of the urban drainage system can be obtained, which can be 30%, 40% and 45% respectively, and the obtained additional incentive indicators are 115%. This application does not impose any special restrictions on the calculation of additional incentive indicators.

[0104] S203: Determine the basic operating indicators of the urban drainage system, and determine the target operating indicators of the urban drainage system based on the environmental governance indicators, the additional incentive indicators and the basic operating indicators.

[0105] Among them, the basic operation indicators are used to reflect the management and service quality of the urban drainage system in the daily operation process, and the target operation indicators are used to reflect the expected working conditions of the urban drainage system after reconstruction.

[0106] It can be understood that the operation indicator calculation module can obtain the performance data of the sewage collection module, the sewage treatment module, and the green economy module, and use different performance data to determine the effectiveness of the city's drainage system in sewage collection, pollutant reduction, resource utilization, green economy and daily operation management; in addition, the operation indicator calculation module pre-stores the importance of different performance data for environmental governance, and different performance data corresponds to different indicator data; therefore, when determining the target operation indicator, the operation indicator calculation module can add different weights to different indicator data according to the importance of different indicator data.

[0107] Determine the basic operating indicators of the current urban drainage system, and obtain the different weight information corresponding to the different indicator data stored in the operating indicator calculation module; according to the weight information, calculate the weighted indicator values ​​of the environmental governance indicator, additional incentive indicator and basic operating indicator respectively, and determine the target operating indicators of the urban drainage system according to the weighted indicator values.

[0108] For example, the environmental governance index can be 30%, and the corresponding weight information can be 30%; the additional incentive index can be 30%, and the corresponding weight information can be 10%; the basic operation index can be 65%, and the corresponding weight information can be 70%; therefore, the target operation index can be 57.5%. This application does not impose any special restrictions on the form of the index value.

[0109] S204: Optimizing the operation of each module in the urban drainage system based on the target operation index.

[0110] It can be understood that the target operation index can reflect whether the impact of the reconstruction of the urban drainage system is positive or negative, that is, positive and negative environmental effects; according to the positive and negative environmental effects reflected by the target operation index, the impact of the current sewage collection and treatment on the urban drainage system is determined, and then the operation of multiple modules in the urban drainage system is optimized and adjusted; if the impact of the reconstruction of the urban drainage system is positive, it means that the environmental quality of the reconstructed urban drainage system is more significant than that of the urban drainage system before the reconstruction, that is, the efficiency of sewage collection and treatment is higher, and the overall environmental quality is improved. At this time, the environmental governance effect of the urban drainage system is incentive; if the impact of the reconstruction of the urban drainage system is negative, it means that the environmental quality of the reconstructed urban drainage system is not significant or the effect is reduced compared with the urban drainage system before the reconstruction, that is, the efficiency of sewage collection and treatment remains unchanged or is lower, and the environmental quality has not changed or has gradually declined. At this time, the environmental governance effect of the urban drainage system is constrained; therefore, according to the target operation index, the operation of multiple modules in the urban drainage system can be optimized and adjusted.

[0111] In addition, when optimizing different modules according to the target operating indicators, the target operating indicators can also be used to determine the actual cost of the urban drainage system being rebuilt; depending on whether the rebuilt urban drainage system is an incentive or constraint for environmental governance, the proportion of additional incentive costs in the actual costs can be determined, that is, the corresponding incentive costs can be determined based on the additional incentive indicators.

[0112] For example, if the target operating index of the urban drainage system after the reconstruction can be 57.5%, and the operating index of the urban drainage system before the reconstruction can be 45%, then the urban drainage system after the reconstruction has more significant results in environmental quality than the urban drainage system before the reconstruction, that is, the efficiency of sewage collection and treatment is higher, and the overall environmental quality is improved. At this time, the environmental governance effect produced by the urban drainage system is incentive, and the operation of different operation modules is more efficient than before the reconstruction, and there is no need to adjust each operation module; if the actual cost of the sewage collection and treatment service fee of the urban drainage system in that year is I0, and I0 can be calculated based on the actual unit price of the sewage collection and treatment service fee and the actual water sales volume in that year, then the actual cost of the urban drainage system in that year can be I, and I=57.5%×I0.

[0113] The method for calculating sewage collection and treatment service indicators based on environmental effects provided in this embodiment obtains the environmental governance effectiveness data of the urban drainage system, and determines the environmental governance indicators and additional incentive indicators respectively according to the sewage collection effectiveness data, pollutant reduction effectiveness data and green economic parameters in the environmental governance effectiveness data; determines the basic operating indicators of the urban drainage system, and determines the target operating indicators of the urban drainage system based on the environmental governance indicators, additional incentive indicators and basic operating indicators, and optimizes the operation of each module in the urban drainage system based on the target operating indicators. This method improves the overall operating efficiency of the urban drainage system, and based on multiple performance data, more targeted incentives for different aspects of resource utilization and energy-saving performance.

[0114] Figure 3 Schematic diagram of the process of calculating the sewage collection and treatment service index based on environmental effects provided in the embodiment of the present application Figure 2 .like Figure 3 As shown, in this embodiment Figure 2 Based on the embodiment, a method for calculating the sewage collection and treatment service index based on environmental effects is described in detail. The method for calculating the sewage collection and treatment service index based on environmental effects shown in this embodiment includes:

[0115] S301: Obtain environmental management effectiveness data of urban drainage systems.

[0116] Step S301 is similar to the above step S201 and will not be described again.

[0117] S302: Determine the sewage collection effectiveness index of the sewage collection and treatment service according to the sewage collection effectiveness data, and determine the pollutant reduction effectiveness index of the sewage collection and treatment service according to the pollutant reduction effectiveness data.

[0118] Among them, the sewage collection effectiveness index and the pollutant reduction effectiveness index are both environmental governance indicators. The sewage collection effectiveness index is used to measure the comprehensive performance and efficiency of the urban drainage system in sewage collection, and the pollutant reduction effectiveness index is used to measure the comprehensive performance and efficiency of the urban drainage system in sewage treatment and pollutant reduction.

[0119] According to the sewage collection effectiveness data and pollutant reduction effectiveness data, the sewage collection and sewage treatment efficiencies of the urban drainage system are determined during the sewage collection and sewage treatment processes respectively. Based on the sewage collection efficiency data and the sewage treatment efficiency data, the efficiency data are respectively indexed to obtain environmental governance indicators.

[0120] Preferably, the determination of sewage collection effectiveness indicators includes:

[0121] Based on the sewage collection effectiveness data, determine the centralized sewage collection rate of the sewage collection and treatment service and the influent BOD5 concentration of the sewage treatment plant; determine the centralized sewage collection rate threshold and the influent BOD5 concentration threshold of the urban drainage system; determine the first collection index based on the centralized sewage collection rate and the centralized sewage collection rate threshold; determine the second collection index based on the influent BOD5 concentration and the influent BOD5 concentration threshold; determine the sewage collection effectiveness index of the sewage collection and treatment service based on the first collection index and the second collection index.

[0122] Among them, the centralized sewage collection rate is used to indicate the proportion of sewage actually collected in the urban drainage system to the total sewage generation, the influent BOD5 concentration is used to indicate the concentration of BOD5 in the sewage entering the sewage treatment plant, the collection rate threshold is used to indicate the lower limit of the centralized sewage collection rate, and the BOD5 concentration threshold is used to indicate the lower limit of the influent BOD5 concentration of the sewage treatment plant; the collection index is used to measure whether the sewage collection effectiveness of the urban drainage system has reached or exceeded the expected effect.

[0123] It is understandable that the collection index can reflect the sewage collection effectiveness of the urban drainage system from different types of effectiveness data, and the index can also measure the efficiency and coverage of the drainage system in sewage collection; the first collection index reflects the sewage collection effectiveness of the urban drainage system based on the sewage centralized collection rate, and the second collection index reflects the sewage collection effectiveness of the urban drainage system based on the influent BOD5 concentration. This application does not impose any special restrictions on the number and type of collection indicators.

[0124] Based on the sewage collection effectiveness data, determine the centralized sewage collection rate and influent BOD5 concentration of the sewage collection and treatment service, then determine the centralized sewage collection rate threshold and influent BOD5 concentration threshold of the urban drainage system, as well as the benchmark centralized sewage collection rate and benchmark influent BOD5 concentration of the urban drainage system, and then determine the first collection index and the second collection index, and based on the first collection index and the second collection index, determine the sewage collection effectiveness index of the sewage collection and treatment service.

[0125] Specifically, the first collection index is determined by judging the relationship between the centralized sewage collection rate and the centralized sewage collection rate threshold. If the centralized sewage collection rate is not less than the centralized sewage collection rate threshold, the difference between the centralized sewage collection rate and the benchmark centralized sewage collection rate is calculated, and the first collection index is determined based on the difference. If the centralized sewage collection rate is less than the centralized sewage collection rate threshold, the ratio between the difference between the centralized sewage collection rate and the benchmark centralized sewage collection rate and the difference between the centralized sewage collection rate threshold and the benchmark centralized sewage collection rate is calculated, the ratio is indexed, and the indexed ratio is determined as the first collection index. In addition, the first collection index has an upper limit value. When the value of the first collection index exceeds the upper limit value, the value of the first collection index is updated to the upper limit value, and the upper limit value can be, for example, 150%.

[0126] By judging the relationship between the influent BOD5 concentration and the influent BOD5 concentration threshold, the second collection index is determined. If the influent BOD5 concentration is not less than the influent BOD5 concentration threshold, the ratio of the difference between the influent BOD5 concentration and the benchmark influent BOD5 concentration to the benchmark influent BOD5 concentration is calculated, the ratio is indexed, and the indexed ratio is determined as the second collection index; if the influent BOD5 concentration is less than the influent BOD5 concentration threshold, the ratio of the difference between the influent BOD5 concentration and the benchmark influent BOD5 concentration to the difference between the influent BOD5 concentration threshold and the benchmark influent BOD5 concentration is calculated, the ratio is indexed, and the indexed ratio is determined as the second collection index; in addition, the second collection index has an upper limit value. When the value of the second collection index exceeds the upper limit value, the value of the second collection index is updated to the upper limit value, and the upper limit value can be, for example, 150%.

[0127] It can be understood that the benchmark centralized sewage collection rate and the benchmark influent BOD5 concentration are determined based on the historical performance data of the urban drainage system before reconstruction. The benchmark centralized sewage collection rate and the benchmark influent BOD5 concentration are used as a measure of whether the current urban drainage system's effectiveness in environmental governance is positive or negative.

[0128] For example, when the sewage centralized collection rate of the secondary urban drainage system is X 1-1R , the influent BOD5 concentration is X 1-2RThe corresponding centralized sewage collection rate threshold is 70%, the influent BOD5 concentration threshold is 100 mg / L, and the benchmark centralized sewage collection rate is X 1-10 , the benchmark influent BOD5 concentration is X 1-20 ; Determine the centralized sewage collection rate X 1-1R Whether it reaches 70%, influent BOD5 concentration X 1-2R Whether it reaches 100 mg / L, the first collection index and the second collection index are determined based on the judgment result, and then the value of the sewage collection effectiveness index is determined; the specific circumstances include:

[0129] ①When X 1-1R ≥70%, the value of the first collection index is 1+(X 1-1R -X 1-10 ), and the maximum value of the first collection index is 1.5, that is, 150%. If there is (X 1-1R -X 1-10 )<0, the value of the first collection indicator is determined to be 1, and at this time, there is an incentive for the effect of the urban drainage system on environmental governance;

[0130] ②When X 1-1R When <70%, the value of the first collection index is (X 1-1R -X 1-10 ) and (70%-X 1-10 ) ratio, if there exists (X 1-1R -X 1-10 )<0, the value of the first collection indicator is determined to be 0. At this time, the effect of the urban drainage system on environmental governance is constrained;

[0131] ③When X 1-2R When the concentration is ≥100mg / L, the value of the second collection index is 1+(X 1-2R -X 1-20 ) and X 1-20 The ratio of the second collection index is 1.5, that is, 150%. If there is (X 1-2R -X 1-20 )<0, the value of the second collection indicator is determined to be 1, and at this time, there is an incentive for the effect of the urban drainage system on environmental governance;

[0132] ④When X 1-2R When the concentration is less than 100 mg / L, the value of the second collection index is (X 1-2R -X 1-20 ) and (100-X 1-20 ) ratio, if there exists (X 1-2R -X 1-20 )<0, the value of the second collection index is determined to be 0. At this time, the effect of the urban drainage system on environmental governance is constrained;

[0133] In addition, when the first collection index and the second collection index are both 1, the payment for the sewage collection effectiveness is paid in full; when the first collection index or the second collection index is less than 1, it means that the sewage collection effectiveness has not met the expected standards and cannot be paid in full, which reflects the payment constraint; when the first collection index or the second collection index is greater than 1, it means that the sewage collection effectiveness exceeds expectations, generating incentive payment, and at the same time, the maximum values ​​of the first collection index and the second collection index are restricted, indicating the maximum incentive limit, and the maximum values ​​of the first collection index and the second collection index are 1.5; if the first collection index and the second collection index both take the maximum value, the sewage collection effectiveness index is 2.25.

[0134] Preferably, the determination of pollutant reduction effectiveness indicators includes:

[0135] Based on the pollutant reduction effectiveness data, determine the pollutant reduction rate and actual comprehensive effluent water quality of sewage collection and treatment services; determine the pollutant reduction rate threshold and preset effluent water quality of the urban drainage system; determine the first reduction index based on the pollutant reduction rate and the pollutant reduction rate threshold; determine the second reduction index based on the actual comprehensive effluent water quality and the preset effluent water quality; determine the pollutant reduction effectiveness index of sewage collection and treatment services based on the first reduction index and the second reduction index.

[0136] Among them, the reduction index is used to measure whether the pollutant reduction effect of the urban drainage system has reached or exceeded the expected effect. The pollutant reduction rate is used to indicate the reduction ratio of pollutant concentration in sewage during sewage treatment. The actual comprehensive effluent water quality is used to indicate the water quality of sewage after treatment. The pollutant reduction rate threshold is used to indicate the lower limit of the pollutant reduction rate in the sewage treatment process. The preset effluent water quality is used to indicate the effluent water quality target set in advance during the design and operation of the sewage treatment system. For example, the effluent water quality can reach Class A or above standards.

[0137] It is understandable that the reduction index can reflect the sewage treatment effectiveness of the urban drainage system from different types of effectiveness data, and the index can also measure the efficiency of the sewage treatment system in removing pollutants; the first reduction index reflects the sewage treatment effectiveness of the urban drainage system based on the pollutant reduction rate, and the second reduction index reflects the sewage treatment effectiveness of the urban drainage system based on the actual effluent water quality. This application does not impose any special restrictions on the number and type of reduction indicators.

[0138] Based on the pollutant reduction effectiveness data, the pollutant reduction rate and the actual comprehensive effluent water quality of the sewage collection and treatment service are determined, and then the pollutant reduction rate threshold and the preset effluent water quality of the urban drainage system are determined, and then the first reduction index and the second reduction index are determined, and based on the first reduction index and the second reduction index, the pollutant reduction effectiveness index of the sewage collection and treatment service is determined; wherein, the reduction rate thresholds include: a first reduction rate threshold, a second reduction rate threshold and a third reduction rate threshold, and the first reduction rate threshold is greater than the second reduction rate threshold, and the second reduction rate threshold is greater than the third reduction rate threshold.

[0139] Specifically, the first reduction index is determined by judging the relationship between the pollutant reduction rate and the pollutant reduction rate threshold. If the pollutant reduction rate is greater than or equal to the first reduction rate threshold, the first reduction index is determined to be the corresponding first index value, for example, it can be 1.2, that is, 120%; if the pollutant reduction rate is greater than or equal to the second reduction rate threshold, and less than the first reduction rate threshold, the first reduction index is determined to be the corresponding second indicator value, for example, it can be 1, that is, 100%; if the pollutant reduction rate is greater than the third reduction rate threshold, and less than the second reduction rate threshold, the difference between the second reduction rate threshold and the pollutant reduction rate is calculated, and the first reduction index is determined based on the difference; if the pollutant reduction rate is less than or equal to the third reduction rate threshold, the first reduction index is determined to be the corresponding third indicator value, for example, it can be 0.

[0140] The second reduction index is determined by judging the relationship between the actual comprehensive effluent water quality and the preset effluent water quality. If the actual effluent water quality meets the preset effluent water quality, the benchmark effluent standard is obtained, and it is determined whether the benchmark effluent standard meets the preset effluent water quality. If the benchmark effluent standard meets the preset effluent water quality, the second reduction index is determined to be a first preset value, for example, it can be 1, that is, 100%; if the benchmark effluent standard does not meet the preset effluent water quality, the second reduction index is determined to be a second preset value, for example, it can be 1.5, that is, 150%.

[0141] It can be understood that the benchmark effluent standard is determined based on the historical performance data of the urban drainage system before reconstruction, and the benchmark effluent standard can measure whether the current urban drainage system is positive or negative in environmental governance based on the performance data corresponding to the effluent water quality.

[0142] For example, the pollutant reduction rate is X 2-1 , the actual comprehensive effluent quality is X 2-2 , which may include TN, TP, COD, BOD5, SS, NH3-N concentrations; the effluent water quality is preset to be Class A or above, the first reduction rate threshold is 20%, the second reduction rate threshold is 10%, and the third reduction rate threshold is 0; the pollutant reduction rate X is judged respectively 2-1The relationship between the first reduction rate threshold, the second reduction rate threshold, the third reduction rate threshold, and the actual effluent water quality X 2-2 The relationship between the water quality of the preset effluent water is determined according to the judgment result, and the first reduction index and the second reduction index are determined, and then the value of the pollutant reduction effectiveness index is determined; the specific situations include:

[0143] ①When X 2-1 When ≥20%, the value of the first reduction index is 1.2, at which point there is an incentive for the effect of the urban drainage system on environmental governance;

[0144] ②When 10%≤X 2-1 When the pollution reduction rate of the urban drainage pipe after reconstruction is 10 percentage points higher than that before reconstruction, the first reduction index is 1, and the pollution reduction rate of the urban drainage pipe after reconstruction is 10 percentage points higher than that before reconstruction.

[0145] ③When 0<X 2-1 When the ratio is less than 10%, the value of the first reduction index is 1-(10%-X 2-1 ) × 10, at this time, the effect of urban drainage system on environmental governance is constrained;

[0146] ④When X 2-1 When ≤0, the value of the first reduction index is 0, and the effect of the urban drainage system on environmental governance is constrained;

[0147] ⑤When X 2-2 The effluent quality reaches Class A or above. If the benchmark effluent standard before reconstruction was originally lower than Class A, the actual effluent standard is raised. At this time, the value of the second reduction index is 1.5. If the benchmark effluent standard is Class A, the value of the second reduction index is 1. At this time, there is an incentive for the effect of the urban drainage system on environmental governance.

[0148] ⑥If X 2-2 If the effluent quality meets other standards or the annual discharge exceeds the standard by less than 5 times, the value of the second reduction index is 0.7. If the annual discharge exceeds the standard by more than 5 times, the value of the second reduction index is 0. At this time, the effect of the urban drainage system on environmental governance is constrained.

[0149] In addition, when the first reduction index and the second reduction index are both 1, the payment for the pollution reduction effect is paid in full; when the first reduction index or the second reduction index is less than 1, it means that the pollution reduction effect has not reached the expected standard and cannot be paid in full, which reflects the constraint of payment; when the first reduction index or the second reduction index is greater than 1, it means that the pollution reduction effect exceeds expectations and incentive payment is generated. At the same time, the maximum values ​​of the second reduction index and the second reduction index are restricted, indicating the maximum incentive limit, and the maximum value of the first reduction index is 1.2, and the maximum value of the second reduction index is 1.5; if the first reduction index and the second reduction index both take the maximum value, the pollutant reduction effect index is 1.8.

[0150] S303: Determine the environmental management index of the urban drainage system according to the sewage collection effectiveness index and the pollutant reduction effectiveness index.

[0151] It can be understood that when calculating environmental governance indicators, the sewage collection effectiveness of the drainage network is combined with the overall pollutant reduction effectiveness of the drainage system composed of the network and the sewage treatment plant. The different importance levels of sewage collection effectiveness and reduction effectiveness can be set in advance to determine the corresponding weight information, and the weight information of sewage collection effectiveness and reduction effectiveness can be set to 50%, for example.

[0152] For example, if the pollutant reduction effectiveness index is 2.25 and the pollutant reduction effectiveness index is 1.8, and their weight information is 50% respectively, then the pollutant reduction effectiveness index and the pollutant reduction effectiveness index are weighted and summed, and the resulting environmental governance index is 2.025.

[0153] S304: Determine additional incentive indicators for the urban drainage system based on the sludge resource utilization rate, recycled water resource utilization rate and energy-saving and carbon-reduction efficiency.

[0154] Among them, the sludge resource utilization rate is used to indicate the proportion of sludge generated in the sewage treatment process that is utilized as resources, the recycled water resource utilization rate is used to indicate the proportion of sewage that meets the reuse standards after treatment and is reused, and the energy-saving and carbon reduction efficiency is used to indicate the energy-saving effect of the sewage treatment system during the treatment process.

[0155] According to the sludge resource utilization rate, recycled water resource utilization rate and energy conservation and carbon reduction efficiency, the indirect effects of the urban drainage system in sludge resource reuse, recycled water reuse and energy conservation after sewage treatment are determined respectively, and the indirect effect data are processed as indicators to obtain additional incentive indicators.

[0156] Preferably, additional incentive indicators for urban drainage systems are determined based on the sludge resource utilization rate, recycled water resource utilization rate and energy-saving and carbon-reduction efficiency, including:

[0157] Obtain the resource utilization threshold and energy conservation and carbon reduction threshold for sewage treatment in the urban drainage system; if the sludge resource utilization rate and the recycled water resource utilization rate meet the resource utilization threshold and the energy conservation and carbon reduction efficiency meet the energy conservation and carbon reduction threshold respectively, then trigger additional incentives for sewage treatment in the urban drainage system; determine the additional incentive indicators for the urban drainage system based on the triggering of the additional incentives.

[0158] Among them, the resource utilization threshold is used to indicate the lower efficiency limit that the sludge resource utilization rate and the recycled water resource utilization rate need to reach, and the energy-saving and carbon-reduction threshold is used to indicate the lower efficiency limit that the energy-saving and carbon-reduction efficiency needs to reach.

[0159] It can be understood that the resource utilization threshold and energy conservation and carbon reduction threshold are different efficiency values ​​set for sludge resource reuse and recycled water reuse and energy conservation respectively, and can also be set to the same efficiency value. For example, the resource utilization thresholds for sludge resource reuse, recycled water reuse and energy conservation can all be set to 50%.

[0160] Obtain the resource utilization threshold and energy-saving and carbon reduction threshold of the urban drainage system, and respectively determine whether the sludge resource utilization rate and the recycled water resource utilization rate meet the resource utilization threshold, and whether the energy-saving and carbon reduction efficiency meets the energy-saving and carbon reduction threshold; if the sludge resource utilization rate and the recycled water resource utilization rate do not meet the corresponding resource utilization threshold, and the energy-saving and carbon reduction efficiency does not meet the energy-saving and carbon reduction threshold, the corresponding additional incentives cannot be triggered; if the sludge resource utilization rate and the recycled water resource utilization rate meet the resource utilization threshold respectively, and the energy-saving and carbon reduction efficiency meets the energy-saving and carbon reduction threshold, the additional incentive for sewage treatment can be triggered, and based on the additional incentive triggering conditions for sludge resource reuse, recycled water reuse and energy conservation, determine the additional incentive indicators for the urban drainage system.

[0161] Preferably, the additional incentive indicators include: a first incentive indicator, a second incentive indicator and a third incentive indicator, which trigger additional incentives for sewage treatment in the urban drainage system, including:

[0162] If the sludge resource utilization rate is not less than the resource utilization threshold, the first incentive indicator of sewage treatment will be triggered; if the recycled water resource utilization rate is not less than the resource utilization threshold, the second incentive indicator of sewage treatment will be triggered; if the energy-saving and carbon reduction efficiency is not less than the energy-saving and carbon reduction threshold, the third incentive indicator of sewage treatment will be triggered.

[0163] Among them, the first incentive indicator is used to indicate that the sludge resource utilization rate meets the resource utilization threshold, the second incentive indicator is used to indicate that the recycled water resource utilization rate meets the resource utilization threshold, and the third incentive indicator energy-saving and carbon reduction efficiency meets the energy-saving and carbon reduction threshold.

[0164] It is understandable that the sludge resource utilization rate, recycled water resource utilization rate and energy conservation and carbon reduction efficiency correspond to different incentive indicators, and there is no correlation between the corresponding incentive indicators.

[0165] For example, the total social capital investment Ip is pre-set in the operation indicator calculation module. When calculating the incentive fee corresponding to the additional incentive indicator, the maximum incentive payment cap B is set based on the total social capital investment Ip. max , and 3% of the total social capital investment is used as the upper limit of additional incentive payment, which can be specifically: B max =(I p ×3%) / Y; the incentive payment for the sludge resource utilization part is B1, the incentive payment for the recycled water resource utilization part is B2, the incentive payment for energy saving or carbon reduction part is B3, the operation period of the rebuilt urban drainage system is Y, the specific additional incentive index can be B=B1+B2+B3, and the additional incentive payment can also be B=B1+B2+B3; the specific additional incentive triggering conditions for sludge resource reuse, recycled water reuse and energy conservation are as follows:

[0166] First, if the sludge resource utilization rate reaches 50%, the incentive payment item B1 will be activated, and the incentive payment B1 for the sludge resource utilization part will be B max ×0.5; Second, if the utilization rate of recycled water resources (excluding discharge to rivers and lakes) reaches 50%, the incentive payment item B2 will be activated, and the incentive payment B2 for the utilization of recycled water resources will be B max ×0.2; Third, if the overall energy saving or carbon reduction rate of the project reaches 50%, the incentive payment item B3 will be activated, and the incentive payment B3 for the energy saving or carbon reduction part will be B max ×0.3.

[0167] S305: Determine basic operating indicators of the urban drainage system.

[0168] S306: Obtain preset weight parameters of the urban drainage system.

[0169] S307: The environmental governance index and the additional incentive index are updated respectively according to the preset weight parameters.

[0170] S308: Determine the target operating indicators of the urban drainage system based on the basic operating indicators, the updated environmental governance indicators and the additional incentive indicators.

[0171] Determine the basic operating indicators of the current urban drainage system, and obtain the preset weight parameters stored in the operating indicator calculation module; calculate the weighted indicator values ​​of the environmental governance indicator, the additional incentive indicator and the basic operating indicator according to the preset weight parameters, and update the environmental governance indicator and the additional incentive indicator according to the weighted indicator data; determine the target operating indicators of the urban drainage system according to the basic operating indicators and the updated environmental governance indicator and the additional incentive indicator.

[0172] It can be understood that the additional incentive index is the corresponding indicator information when the urban drainage system produces significant positive results in environmental governance methods. Therefore, the weight information corresponding to the additional incentive index is not normalized with the environmental governance index and the basic operation index. For example, the weight information of the environmental governance index is 30%, the weight information of the basic operation index is 70%, and the weight information of the additional incentive index can be 10%.

[0173] For example, the preset weight parameters include: environmental governance index -30%, additional incentive index -10% and basic operation index -70%. When the environmental governance index is 30%, the additional incentive index is 30% and the basic operation index is 65%, weighted calculations are performed according to the weight parameters corresponding to different indicators, and the sum of the weighted calculation values ​​is calculated to obtain the target operation index, and the target operation index is 57.5%.

[0174] S309: Optimizing the operation of each module in the urban drainage system based on the target operation index.

[0175] Step S309 is similar to the above step S204 and will not be described again.

[0176] The method for calculating the sewage collection and treatment service index based on environmental effects provided in this implementation obtains the environmental governance performance data of the urban drainage system, and determines the sewage collection performance index of the sewage collection and treatment service according to the sewage collection performance data in the environmental governance performance data, determines the pollutant reduction performance index of the sewage collection and treatment service according to the pollutant reduction performance data, and then determines the environmental governance index of the urban drainage system according to the sewage collection performance index and the pollutant reduction performance index; determines the additional incentive index of sewage treatment in the urban drainage system according to the sludge resource utilization rate, the recycled water resource utilization rate and the energy conservation and carbon reduction efficiency; determines the basic operation index of the urban drainage system, and obtains the preset weight parameters of the urban drainage system, and updates the environmental governance index and the additional incentive index according to the preset weight parameters; determines the target operation index of the urban drainage system according to the basic operation index and the updated environmental governance index and the additional incentive index, and optimizes the operation of each module in the urban drainage system based on the target operation index. This method improves the overall operation efficiency of the urban drainage system, and based on multiple performance data, more targetedly encourages resource utilization and energy conservation performance in different aspects, promotes pollution reduction and carbon reduction, and improves the overall effect of environmental governance.

[0191] The determination module 402 is also used to determine the pollutant reduction rate threshold and preset effluent water quality of the urban drainage system.

[0192] The determination module 402 is further used to determine a first reduction index according to the pollutant reduction rate and the pollutant reduction rate threshold, and the reduction index is used to measure whether the pollutant reduction effect of the urban drainage system reaches or exceeds the expected effect.
