Description

Technical Field

[0001] The present invention relates to the technical field of overflow control, and in particular to an overflow equipment control method, device and storage medium. Background Art

[0002] Combined sewerage is a drainage method that uses the same pipe system to collect and transport sewage and wastewater. Against the backdrop of climate change and urban creep, frequent extreme weather and rapid urban development have posed great challenges to the discharge of sewage through combined sewers.

[0003] Currently, combined sewers often use adjustable overflow devices to control the discharge of sewage to downstream receiving water bodies. However, under different water environments and water circulation conditions, even with the same amount of sewage discharged, the water quality of the downstream receiving water bodies can vary significantly. Therefore, the sewage discharge process can easily lead to serious pollution of the downstream receiving water bodies, resulting in huge economic losses and even ecological disasters.

[0004] Therefore, how to provide an effective solution to prevent the downstream from suffering from water pollution has become a difficult problem that needs to be solved urgently in the existing technology. Summary of the Invention

[0005] In order to solve the problem in the prior art that sewage discharge under the combined system easily leads to pollution of downstream water bodies, the purpose of the present invention is to provide an overflow equipment control method, device and storage medium, so that when controlling the discharge of sewage to the downstream receiving water body by adjusting the overflow equipment, the water quality of the downstream receiving water body is comprehensively considered, so that the water quality of the downstream receiving water body meets the water quality standards, avoids pollution of the downstream receiving water body, and facilitates practical promotion and application.

[0006] In a first aspect, the present invention provides an overflow device control method for controlling an overflow device in a combined sewer, comprising:

[0007] Acquire water environment and water circulation data upstream and downstream of the overflow device, wherein the water environment and water circulation data include water environment data generated by natural activities and water circulation data generated by human activities. The upstream and downstream of the overflow device include the upstream flow-generating and confluence area of the overflow device and the downstream receiving water body of the overflow device;

[0009] Based on the overflow equipment operating conditions corresponding to various predetermined extreme scenarios, the overflow equipment operating conditions corresponding to the target extreme scenarios are determined to control the overflow equipment, wherein the overflow equipment operating conditions corresponding to various extreme scenarios refer to the operating conditions corresponding to the overflow equipment when the water quality of the downstream water body meets the water quality standards under various extreme scenarios.

[0010] Through the above design, the present invention obtains the water environment and water circulation data upstream and downstream of the overflow device, matches the water environment and water circulation data with the historical water environment and water circulation data corresponding to a plurality of predetermined extreme scenarios, obtains the target extreme scenario that matches the water environment and water circulation data, and then determines the overflow device operating conditions corresponding to the target extreme scenario based on the overflow device operating conditions corresponding to the various predetermined extreme scenarios to control the overflow device. In this way, when controlling the discharge of sewage to the downstream receiving water body by adjusting the overflow device, the water quality of the downstream receiving water body is comprehensively considered to ensure that the water quality of the downstream receiving water body meets the water quality standards, thereby avoiding pollution of the downstream receiving water body and facilitating practical promotion and application. Moreover, by matching the water environment and water circulation data, the matching target extreme scenario is determined, and according to the overflow device operating conditions corresponding to the various extreme scenarios, the overflow device operating conditions corresponding to the target extreme scenario are determined to control the overflow device, thereby being able to complete the control of the overflow device very simply and quickly. In addition, during the control process of the overflow equipment, the automatic management and control of the overflow equipment can be guided in real time, without the need to deploy manpower on duty at the overflow equipment end, thus reducing the investment in human resources.

[0011] In one possible design, before obtaining the water environment and water circulation data upstream and downstream of the overflow device, the method further includes:

[0023] If the pollution index at the downstream receiving water body does not meet the water quality standard, a new operating condition is selected from the proposed operating conditions, and the historical water environment and water cycle data corresponding to any of the extreme scenarios, as well as the newly selected operating condition, are used as boundary conditions of the coupled model for simulation until the pollution index at the downstream receiving water body meets the water quality standard;

[0024] The operating condition corresponding to when the pollution index at the downstream water body meets the water quality standard is used as the operating condition corresponding to any of the extreme scenarios.

[0042] Example

[0043] In order to solve the problem in the prior art that sewage discharge under the combined sewer system easily leads to pollution of downstream water bodies, the purpose of the present invention is to provide an overflow equipment control method, device and storage medium, so that when controlling the discharge of sewage to the downstream receiving water body by adjusting the overflow equipment, comprehensive consideration is given to whether the water quality of the downstream receiving water body meets the water quality standards, so that when discharging sewage to the downstream receiving water body, the water quality of the downstream receiving water body is ensured to meet the water quality standards, avoiding serious pollution of the downstream receiving water body, and facilitating practical promotion and application.

[0044] The overflow device control method provided in the embodiment of the present application can be applied to a server, a remote backend management terminal, or an edge computing device near the overflow device. It is understood that the execution subject does not constitute a limitation on the embodiment of the present application.

[0045] The overflow equipment control method provided in the embodiment of the present application will be described in detail below.

[0046] like Figure 1FIG. 1 is a flow chart of an overflow device control method provided in the first aspect of an embodiment of the present application. The overflow device control method may include the following steps:

[0047] Step S101: Acquire water environment and water circulation data upstream and downstream of the overflow equipment.

[0048] In the embodiment of the present application, the overflow device can be but is not limited to an overflow well, overflow weir, overflow valve, overflow flap, overflow pump or overflow orifice in a combined sewer. The overflow device has the function of dynamically adjusting the interception multiple and / or controlling opening and closing according to changes in the water environment.

[0049] The water environment and water circulation data upstream and downstream of the overflow device may be the currently monitored water environment and water circulation data, or the predicted water environment and water circulation data after the current time point.

[0050] The water environment and water cycle data include water environment data generated by natural activities and water cycle data generated by human activities. The water environment and water cycle data may include, but is not limited to, hydrological data, hydrodynamic data, water quality data, hydraulic machinery data, sewer engineering data, and pollution treatment engineering data.

[0051] The upstream and downstream of the overflow device include the upstream flow-generating and confluence area of the overflow device and the downstream water body of the overflow device. The upstream flow-generating and confluence area of the overflow device may be the urban human activity area and natural surface upstream of the overflow device. The downstream water body of the overflow device includes but is not limited to pipelines, artificial channels, sewage treatment plants, rivers, lakes and groundwater downstream of the overflow device.

[0052] Step S102: Match the water environment and water cycle data with the historical water environment and water cycle data corresponding to a plurality of predetermined extreme scenarios to obtain a target extreme scenario that matches the water environment and water cycle data.

[0053] The historical water environment and water cycle data include historical water environment data and historical water cycle data. Similarly, the historical water environment and water cycle data may include, but is not limited to, hydrological data, hydrodynamic data, water quality data, hydraulic machinery data, sewer engineering data, and pollution treatment engineering data.

[0054] In an embodiment of the present application, multiple extreme scenarios are determined in advance based on historical water environment and water circulation data. After obtaining the water environment and water circulation data upstream and downstream of the overflow equipment, the water environment and water circulation data can be matched with the historical water environment and water circulation data corresponding to the multiple extreme scenarios determined in advance, and the extreme scenario corresponding to the historical water environment and water circulation data with the highest matching degree is selected as the target extreme scenario to match the water environment and water circulation data.

[0055] Under the combined sewer system, factors that have a significant impact on sewage discharge include rainfall. Therefore, in one or more embodiments, when matching water environment and water cycle data with historical water environment and water cycle data corresponding to a plurality of predetermined extreme scenarios, the data such as rainfall intensity and delay within a period of time in the water environment and water cycle data can be matched with the data such as rainfall intensity and delay within a period of time in the historical water environment and water cycle data corresponding to the plurality of extreme scenarios. For example, the rainfall intensity, delay, and frequency of occurrence (within a period of time) in the acquired water environment and water cycle data can be counted, and the statistical results can be matched with the rainfall intensity, delay, and frequency of occurrence (within a period of time) in each historical water environment and water cycle data, thereby obtaining the historical water environment and water cycle data with the highest degree of matching with the water environment and water cycle data.

[0056] Step S103 . Based on the predetermined overflow equipment operating conditions corresponding to various extreme scenarios, determine the overflow equipment operating condition corresponding to the target extreme scenario to control the overflow equipment.

[0057] Among them, the overflow equipment operating conditions corresponding to various extreme situations refer to the operating conditions corresponding to the overflow equipment when the water quality of the downstream water body meets the water quality standards under various extreme situations, and the water quality of the downstream water body meets the water quality standards means that the water quality of the downstream water body is within the normal water quality standard range.

[0058] In the embodiments of the present application, a coupling model is pre-established to simulate the operating conditions corresponding to various extreme scenarios, provided that the downstream receiving water body meets water quality standards. After obtaining a target extreme scenario that matches the water environment and water cycle data, the overflow equipment operating conditions corresponding to the target extreme scenario can be determined based on the overflow equipment operating conditions corresponding to the various extreme scenarios. The overflow equipment is then controlled based on the determined overflow equipment operating conditions. The process of establishing the coupling model is described in detail later in the specification.

[0059] The overflow device operating condition may be the open or closed state of the overflow device, or the interception multiple of the overflow device, etc., which is not specifically limited in the embodiments of the present application.

[0060] Thus, through the overflow device control method of the aforementioned steps S101 to S103, the present invention obtains water environment and water circulation data upstream and downstream of the overflow device, matches the water environment and water circulation data with historical water environment and water circulation data corresponding to a plurality of predetermined extreme scenarios, obtains a target extreme scenario that matches the water environment and water circulation data, and then, based on the overflow device operating conditions corresponding to the predetermined various extreme scenarios, determines the overflow device operating conditions corresponding to the target extreme scenario to control the overflow device. In this way, when controlling the discharge of sewage to the downstream receiving water body by adjusting the overflow device, whether the water quality of the downstream receiving water body meets the water quality standards is comprehensively considered, so that when discharging to the downstream receiving water body, the water quality of the downstream receiving water body can be ensured to meet the water quality standards, avoiding pollution of the downstream receiving water body, and facilitating practical promotion and application. Moreover, by matching the water environment and water circulation data, a matching target extreme scenario is determined, and based on the overflow device operating conditions corresponding to the various extreme scenarios, the overflow device operating conditions corresponding to the target extreme scenario are determined to control the overflow device, thereby enabling a very simple and rapid completion of the overflow device control. In addition, during the control process of the overflow equipment, the automatic management and control of the overflow equipment can be guided in real time, without the need to deploy manpower on duty at the overflow equipment end, thus reducing the investment in human resources.

[0061] See also Figure 2 Based on the technical solution of the first aspect mentioned above, this embodiment also specifically proposes a possible design for determining the overflow equipment working conditions corresponding to various extreme situations. Determining the overflow equipment working conditions corresponding to various extreme situations may include but is not limited to the following steps S201 to S207.

[0062] Step S201: Obtain historical water environment and water circulation data upstream and downstream of the overflow equipment.

[0063] Historical water environment and water cycle data may include, but are not limited to, hydrological data, hydrodynamic data, water quality data, hydraulic machinery data, sewer engineering data, and pollution treatment engineering data.

[0064] Step S202: Based on the historical water environment and water cycle data of the upstream runoff area of the overflow device, a first mechanism model is established to simulate the overflow volume and overflow water quality of the overflow device.

[0065] The first mechanism model may be, but is not limited to, a 0-dimensional, 1-dimensional, 2-dimensional or 3-dimensional lumped or distributed mechanism model. Among them, a 0-dimensional mechanism model may be a first mechanism model established based on the historical water environment and water cycle data corresponding to the point by considering the upstream runoff area of the overflow device as a point (such as a lake as a point). A 0-dimensional mechanism model may be a first mechanism model established based on the historical water environment and water cycle data corresponding to the point by considering the upstream runoff area of the overflow device as a line, divided into upstream and downstream. A first mechanism model established based on the historical water environment and water cycle data corresponding to the upstream and downstream is a 1-dimensional mechanism model. A 2-dimensional mechanism model may be a first mechanism model established based on the historical water environment and water cycle data corresponding to each point on the surface by considering the upstream runoff area of the overflow device as a surface. A 3-dimensional mechanism model may be a first mechanism model established based on the historical water environment and water cycle data corresponding to each point in the surface by considering the upstream runoff area of the overflow device as a solid. A 3-dimensional mechanism model may be a first mechanism model established based on the historical water environment and water cycle data corresponding to each point in the solid is a 3-dimensional mechanism model.

[0066] Establishing the first mechanism model may include but is not limited to the following steps S2021 to S2022.

[0067] Step S2021: After sorting and correcting the historical water environment and water cycle data of the upstream runoff area, a numerical first initial mechanism model is established.

[0068] Step S2022. Take the historical water environment and dynamically changing data in the water cycle data of the upstream runoff area as input items, and the overflow volume and overflow water quality of the overflow equipment as output items, calibrate and verify the first initial mechanism model, and obtain the first mechanism model that simulates the overflow volume and overflow water quality of the overflow equipment.

[0069] The calibration and verification of the first initial mechanism model can be completed manually or by heuristic algorithms. By continuously adjusting the numerical parameters in the model, the error between the overflow volume and overflow water quality data (time series data) at the overflow device and the simulated overflow volume and overflow water quality data (time series data) can be reduced or the credibility can be increased as much as possible until it reaches an acceptable range.

[0070] In the embodiment of the present application, the input items of the first initial mechanism model are dynamically changing data in the historical water environment and water cycle data of the upstream production and confluence area. For example, the historical water environment and water cycle data of the upstream production and confluence area include sewer section data, water consumption and water quality caused by human activities, water catchment area range, underlying surface data, atmospheric pollutant deposition data, groundwater seepage, hydraulic machinery parameters and sewage treatment parameters. Among them, water consumption and water quality caused by human activities, atmospheric pollutant deposition data and groundwater seepage are dynamically changing data. Therefore, the water consumption and water quality caused by human activities, atmospheric pollutant deposition data and groundwater seepage can be used as the input items of the first initial mechanism model.

[0071] Step S203: Based on the historical water environment and water cycle data of the downstream water body of the overflow device, the overflow volume and overflow water quality of the overflow device, a second mechanism model simulating the water quality of the downstream water body of the overflow device is established.

[0072] Similarly, the second mechanism model may also be, but not limited to, a 0-dimensional, 1-dimensional, 2-dimensional, or 3-dimensional lumped or distributed mechanism model, which will not be described in detail here.

[0073] Establishing the second mechanism model may include but is not limited to the following steps S2031 to S2032.

[0074] Step S2031: After sorting and correcting the historical water environment and water cycle data of the downstream water body, a numerical second initial mechanism model is established.

[0075] In step S2032, the historical water environment and water circulation data of the downstream water body of the overflow device, the overflow volume and overflow water quality of the overflow device are used as input items, and the water quality of the downstream water body of the overflow device is used as output item. The second initial mechanism model is calibrated and verified to obtain a second mechanism model that simulates the water quality of the downstream water body of the overflow device.

[0076] The calibration and verification of the second initial mechanism model can be completed manually or through a heuristic algorithm. By continuously adjusting the numerical parameters in the model, the error between the water quality (time series data) of the downstream receiving water body and the simulated water quality (time series data) of the downstream receiving water body can be reduced or the credibility can be increased as much as possible until it reaches an acceptable range.

[0077] Historical water environment and water cycle data for the downstream water body of the overflow device may include, but is not limited to, river and lake cross-sectional data downstream of the overflow device, river and lake water volume and quality, and water volume and quality data from other point and non-point sources. The water quality of the downstream water body of the overflow device may be the water quality at a key point downstream of the overflow device.

[0078] Step S204: Couple the first mechanism model with the second mechanism model to obtain a coupled model.

[0079] In the embodiment of the present application, the output of the first mechanism model can be used as the input of the second mechanism model to obtain the coupling model. More specifically, the first mechanism model simulates the overflow volume and overflow water quality of the overflow device, while the input of the second mechanism model is the historical water environment and water cycle data of the downstream receiving water body, the overflow volume and overflow water quality of the overflow device. Therefore, the historical water environment and water cycle data of the downstream receiving water body and the output of the first mechanism model can be used as the input of the second mechanism model to obtain the coupling model.

[0080] Step S205: Statistically analyze the historical water environment and water circulation data upstream and downstream of the overflow equipment to obtain multiple extreme scenarios.

[0081] Statistical analysis of historical water environment and water cycle data upstream and downstream of the overflow device can be performed, including but not limited to historical rainfall data, human water consumption and water quality, river and lake hydrology and water quality, and other point and non-point source hydrology and water quality data, to generate multiple extreme scenarios. Historical rainfall data can be used to generate a rainfall intensity-delay-frequency (IDF) curve, human water consumption can be used to generate a time-varying curve for human domestic water consumption, and human water quality can be used to generate an average water quality load for domestic water use. River and lake hydrology can be used to generate the hydrological conditions of rivers and lakes under different rainfall frequencies, and river and lake water quality can be used to generate the average water quality of rivers and lakes. Other point and non-point source hydrology can be used to generate the hydrological conditions of other point and non-point sources under different rainfall frequencies, and the water quality of other point and non-point sources can be used to generate the average water quality of other point and non-point sources. Multiple extreme scenarios can be formulated using the aforementioned time-varying curves for human water consumption, which can be configured for different rainfall intensities, delays, frequencies, and rainfall time periods.

[0082] Step S206: Develop corresponding working conditions of the overflow equipment under different conditions.

[0083] The overflow device operating condition can be the device's open or closed state, or the overflow device's cutoff factor. For example, if the overflow device operating condition is the overflow device's open or closed state, when designing the overflow device's corresponding operating conditions under different conditions, the overflow device can be designed to open when a rainfall delay of x hours occurs and the water level at the overflow device exceeds y meters, and close when these conditions are not met. The rainfall delay of x hours and the water level y can be set according to actual circumstances.

[0084] Step S207: Simulate the historical water environment and water cycle data corresponding to various extreme scenarios, as well as the proposed operating conditions, as boundary conditions of the coupling model to obtain the operating conditions corresponding to various extreme scenarios when the downstream water body meets the water quality standards.

[0085] Step S207 may specifically include the following steps S2071 to S2073.

[0086] Step S2071. For any extreme scenario among multiple extreme scenarios, the historical water environment and water cycle data corresponding to any extreme scenario, as well as one of the proposed operating conditions, are used as boundary conditions of the coupling model to simulate and obtain pollution indicators at the downstream water body.

[0087] The pollution index may be, but is not limited to, water quality concentration, heavy metal concentration, or ecological index. The ecological index may refer to the number of organisms such as fish or algae in the water body.

[0088] Step S2072. If the pollution index at the downstream water body does not meet the water quality standard, a new operating condition is selected from the proposed operating conditions, and the historical water environment and water cycle data corresponding to any of the extreme scenarios, as well as the reselected operating conditions, are used as boundary conditions of the coupling model for simulation until the pollution index at the downstream water body meets the water quality standard.

[0089] The water quality standards may include, but are not limited to, surface water environmental standards, black and odorous water standards, the Carlson Index, or trophic status assessment standards. The pollution indicators at the downstream receiving water body meeting the water quality standards mean that the pollution indicators at the downstream receiving water body are within the normal range, i.e., the downstream receiving water body is not polluted.

[0090] Step S2073: The working condition corresponding to when the pollution index at the downstream water body meets the water quality standard is used as the working condition corresponding to any of the extreme scenarios.

[0091] For each extreme case, the working conditions corresponding to each extreme case can be obtained through the process of steps S2071 to S2073, thereby obtaining the working conditions corresponding to multiple extreme situations when the downstream water body meets the water quality standards.

[0092] Through the aforementioned possible design one, a coupling model of the water quality of the downstream receiving water body of the overflow equipment can be established, and the coupling model can be used to simulate the working conditions corresponding to various extreme scenarios when the downstream receiving water body meets the water quality standards, so that in the subsequent control process of the overflow equipment, the overflow equipment can be controlled very conveniently and quickly according to the overflow equipment working conditions corresponding to various extreme scenarios.
