Description

[0002] With the rapid expansion of urban population, the existing drainage system and drainage capacity cannot meet the demand of urban sewage discharge. With the development of economy and the enhancement of environmental awareness, and in addition to the increasing value of water resources, in order to better utilize various water resources, rain and sewage separation system emerges as the times require. Rain and sewage separation system refers to separating rainwater and sewage, conveying each by a pipeline, and discharging or subsequent treatment. Rainwater is directly discharged to a river through a rainwater pipe network, and sewage is collected through a sewage pipe network and then sent to a sewage treatment plant for treatment, and after the water quality meets the corresponding national or local standards, it is discharged into the river, which can prevent the river from being polluted. The collection and centralized management and discharge of rainwater can reduce the impact of water quantity on the sewage treatment plant and ensure the treatment efficiency of the sewage treatment plant. Therefore, rain and sewage separation pump stations are built in various places to relieve drainage pressure.

[0003] The existing drainage pump station operation scheduling is mostly based on the experience of staff for decision-making, and with the rise of communication, automation and artificial intelligence technology, the operation decision of the drainage pump station also needs to be combined with theoretical derivation to realize intelligent transformation.

[0004] However, the current drainage pump station scheduling method generally has the following shortcomings: 1. The scheduling scheme is mostly scheduled according to the operation of the pipe network or the water plant; 2.

[0062] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0063] like Figure 1 As shown, this embodiment provides a drainage pumping station, including a rainwater collection tank, a forebay, and a regulating tank.

[0064] The rainwater collection tank has a rainwater inlet gate at the front end to control the rainwater entering the rainwater pipes, and a rainwater outlet gate at the rear end to control the discharge of water in the rainwater collection tank to the receiving water body. The forebay is located next to the rainwater collection tank. After the rainwater inlet gate is opened, the rainwater from the rainwater pipes can enter the rainwater collection tank and the forebay respectively. At the same time, the forebay also collects rainwater overflowing from manhole covers on the road.

[0065] The outlet of the forebay is connected to the regulating reservoir through the inlet gate of the regulating reservoir. A sewage pump is installed in the forebay to discharge the sewage / sludge in the forebay into the sewage pipe.

[0066] The storage tank is equipped with an air venting pump connected to the sewage pipeline. This allows water to be discharged into the sewage pipeline when the liquid level in the storage tank increases, and the sewage in the sewage pipeline flows to the downstream sewage treatment plant.

[0067] When the water level in the storage tank increases to the point where the venting pumps are sufficient to discharge the water, a rainwater pump can be installed in the rainwater collection tank to pump the water from the storage tank into the rainwater collection tank.

[0068] Specifically, the terrain of the rainwater pipes, forebay, and storage tank decreases sequentially, allowing rainwater to enter the rainwater collection tank, forebay, and storage tank under the influence of gravity.

[0069] The receiving water body is a river, lake, ocean, or other water body that receives discharged or treated wastewater. In this embodiment, the drainage pumping station is located next to a river, so the receiving water body is a river. Of course, if the drainage pumping station is located at the seaside, the receiving water body is an ocean.

[0070] like Figure 2 As shown, this embodiment providesFigure 1 The scheduling method of the drainage pump station comprises the following steps:

[0071] S100: input current pipe network parameters, pump station parameters and downstream sewage plant parameters into a running mode judgment model to determine whether the running mode of the drainage pump station is a rainstorm mode or a non-rainstorm mode, wherein the pipe network parameters comprise a rainwater pipe liquid level, the pump station parameters comprise a front pool liquid level and a regulation and storage pool liquid level, and the downstream sewage plant parameters comprise a downstream sewage plant inflow.

[0072] The running mode judgment model is mainly determined by static parameters of the pump station, such as front pool capacity parameters (volume, depth), rainwater pipe parameters (volume, geometric size), various water pump displacement related parameters (outlet height, Q-H curve parameters) and the like. These parameters are determined after the pump station is built.

[0073] The current pipe network parameters, pump station parameters and downstream sewage plant parameters are dynamic parameters, which change in real time. By inputting these real-time parameters into the running mode judgment model determined by the static parameters and adding some constraint conditions, the running mode of the drainage pump station can be simulated.

[0074] S200: output the scheduling arrangement of the drainage pump station in the running mode according to the running mode until the drainage pump station running meets safety requirements.

[0075] According to whether the running mode is a rainstorm mode or a non-rainstorm mode, the corresponding scheduling method can be obtained, and the safety requirements met by the drainage pump station running can be safety factors, regulation and storage failure conditions and the like.

[0076] In step S100, the running mode judgment model is established according to various parameters of the drainage pump station, and the specific method is as follows:

[0077] Determine a simulation iteration step length, such as 1 minute, establish a pipe liquid level model, a front pool liquid level model, a regulation and storage pool liquid level model, various water pump displacement models and a downstream sewage plant inflow model, and set man-machine interaction constraint variables and limit value variables.

[0078] The man-machine interaction constraint variables comprise a safety factor and a number of available water pumps. The safety factor ranges from 0 to 1 and is used to adjust the expected safety. The smaller the value, the higher the running strategy strength. The number of available water pumps is used to control the running equipment start condition, which facilitates the adjustment of the running strategy when the equipment is damaged.

[0079] The limit variables include storage failure events and corresponding parameters. The storage failure events include three types: rainwater pipe level exceeding the limit, forebay level exceeding the limit, and sewage treatment plant inlet flow exceeding the limit. The corresponding parameters for the storage failure events are the pipe level exceeding the limit, the forebay level exceeding the limit, and the sewage treatment plant inlet flow exceeding the limit, respectively. These level values ​​are variables and can be manually modified.

[0080] The models for pipeline level, forebay level, regulating reservoir level, as well as the drainage volume models of each pump and the inflow volume model of the downstream water plant, can be established using methods such as reservoir capacity relationship curves, empirical formulas, and machine learning.

[0081] In this embodiment, the reservoir capacity relationship district is adopted. Taking the pipeline liquid level model as an example, the next stage of rainwater pipeline liquid level is determined by the rainfall, the current rainwater pipeline liquid level, and the rainwater pipeline capacity parameters (volume and size). In this model, the rainfall, the current rainwater pipeline liquid level, and the rainwater pipeline capacity parameters (volume and size) are independent variables, and the next stage of rainwater pipeline liquid level is the dependent variable.

[0082] Similarly, the forebay level model determines the next stage of the forebay level by using the rainwater pipe level, the current forebay level, and the forebay capacity parameters (volume and depth). This model can describe the dynamic process of the forebay level changing with the change in the forebay inflow rate after the rainwater inlet gate is opened.

[0083] Storage tank level model: This model determines the next stage of the storage tank level based on the forebay level, the current storage tank level, and the storage tank capacity parameters (volume and depth). It describes the dynamic process of how the storage tank level changes with the inflow rate after the storage tank gates are opened.

[0084] Pump discharge capacity model: This is a flow-head model, which is determined by the pump selection.

[0085] Downstream water plant inflow model: The inflow to the downstream water plant is determined by the liquid levels in the upstream rainwater pipes, the forebay, and the regulating reservoir.

[0086] It can be seen that the models are related through variables. For example, the pipeline level model and the forebay level model are related through the rainwater pipeline flow rate; the forebay level model and the regulating tank level model are related through the regulating tank inflow rate; and the downstream water plant inflow rate model is related to the regulating tank level, the venting pump flow rate, and the sewage pump flow rate, respectively.

[0087] like Figure 3 As shown, in step S100, the current pipeline parameters, pump station parameters, and downstream sewage treatment plant parameters are input into the operation mode judgment model to determine whether the operation mode of the drainage pump station is a rainstorm mode or a non-rainstorm mode. Specifically, this includes:

[0088] S101: Initialize the rainwater pipe level, forebay level, storage tank, and sewage treatment plant inflow rate. Input the current network parameters (rainwater pipe level, rainwater pipe capacity), pump station parameters (forebay level, storage tank level), and downstream sewage treatment plant parameters (downstream sewage treatment plant inflow rate) as input variables (these input variables will change during simulation). Input these parameters into the operation mode judgment model for simulation calculation. Among them, the rainwater pipe capacity parameters, forebay capacity parameters, storage tank capacity parameters, and various drainage pump parameters are used as static parameters (these parameters remain unchanged for the same pump station). The safety factor and the number of available pumps are used as human-computer interaction variables (the safety of scheduling and the number of pumps available for scheduling are manually defined before the calculation starts, and are fixed values ​​after the calculation starts). The pipe level exceeding the limit, the forebay level exceeding the limit, and the sewage treatment plant inflow exceeding the limit are used as constraint variables. If any variable of pipe level, forebay level, or sewage treatment plant inflow exceeds the corresponding limit level during the calculation, the storage fails and the system switches to the next operation mode.

[0089] S102: The scheduling arrangement of drainage pumping stations corresponding to the non-rainstorm mode is used as the initial operation plan. Iterative simulation is carried out in combination with the predicted inflow. If the storage failure event is triggered, a flood warning is issued. Otherwise, the simulation continues to calculate the critical point of the non-rainstorm mode and the rainstorm mode.

[0090] The scheduling arrangement of drainage pumping stations under non-heavy rain conditions, as the initial operating plan (dry weather strategy), is as follows:

[0091] When emptying the air conditioning storage tank on a sunny day or draining and backwashing it on a rainy day, turn on the venting pump to transport the initial rainwater in the storage tank to the sewage pipe. The venting time is during the low period of sewage volume in the pipe network. When the storage tank is emptied to a certain level, turn off the venting pump.

[0092] Before the critical point, the weather pattern is non-heavy rain; after the critical point, the weather pattern is heavy rain.

[0093] S103: Repeat steps S101 to S102 according to the predicted rainfall value and its upper and lower error limits to obtain the corresponding simulation results;

[0094] In this step, since the rainfall forecast value has errors, when performing steps S101 to S102, three values ​​are input respectively: the rainfall forecast value, the upper limit of the rainfall forecast value, and the lower limit of the rainfall forecast value, and the corresponding simulation results are output.

[0095] S104: Determine the iteration accuracy (deviation) based on the above simulation results, and output the running mode with the highest accuracy.

[0096] Because there is a certain prediction error between the predicted inflow and the actual inflow of the model, the reliability of the operating results is evaluated using a probabilistic approach. For example, if the simulation result shows that the accuracy of the heavy rain mode is 80%, it means that this operating mode is the best strategy in 80% of the samples, while the best strategy in the remaining 20% ​​of the samples is the non-heavy rain mode. Therefore, the structure output by the operating mode judgment model is the heavy rain mode.

[0097] The output of the operation mode judgment model is the operation mode window for a future period of time. Combined with the control logic of each operation mode given at the beginning (the control diagram logic is directly hard-coded, and the corresponding type of control logic is only executed according to the operation mode), the real-time water pump operation status and valve status can be output.

[0098] After the operation mode determination model outputs the corresponding operation mode that the drainage pumping station needs to execute, the drainage scheduling strategy can be executed by controlling the opening and closing states of different gates and pumps.

[0099] The above-mentioned dry weather strategy is adopted when the operating mode output is non-rainstorm mode.

[0100] When the operating mode output is heavy rain mode, the "water environment-water balance-water security" scheme needs to be executed based on the rainfall amount, rainfall process, pipeline network status, pumping station status, and downstream sewage treatment plant inflow status, as follows:

[0101] (1) Water Environment Strategy

[0102] In rainy weather, the interception operation is first performed. The rainwater inlet gate is opened to divert the rainwater to the forebay. If the liquid level in the forebay does not rise, the water environment strategy continues to operate. If the liquid level in the forebay continues to rise, the water balance strategy is operated.

[0103] (2) Water balance strategy

[0104] If the forebay level continues to rise, open the inlet gate of the regulating tank to introduce water from the forebay into the regulating tank. If the regulating tank level stops rising after a period of time, close the inlet gate of the regulating tank and operate the water environment strategy. If the regulating tank level continues to be too high, operate the water safety strategy.

[0105] (3) Water security strategy

[0106] Under the water security strategy, river release operations and / or venting operations will be carried out;

[0107] The aforementioned river discharge operation involves opening the rainwater outlet gate and pumping the water in the storage tank to the rainwater collection tank via the rainwater pump, thereby directly discharging it into the receiving water body. If the liquid level in the storage tank does not rise for a period of time, the rainwater pump and rainwater outlet gate are closed, and a water balance strategy is implemented.

[0108] The venting operation involves turning on the venting pump of the regulating tank to release the water from the tank and transport it to the downstream wastewater treatment plant. If the liquid level in the regulating tank does not rise for a period of time, the venting pump is turned off, and the water balance strategy is activated.

[0109] Considering the requirements of energy-saving operation, different operating strategies have a priority: dry weather > water environment > water balance > water security. During the optimization process, simulations of different operating strategies are used to determine their operational feasibility. Specifically, after confirming the operating mode, simulations are performed sequentially according to the energy-saving level under that mode based on the model input conditions. The simulation results are checked to see if the corresponding limiting variables are exceeded. If not, the strategy is executed; if they are exceeded, the next strategy is executed, and this process is repeated until the optimal operating strategy is determined. The optimization control step size is in hours.

[0111] The operation mode output module 41 inputs the current pipeline parameters, pump station parameters, and downstream sewage treatment plant parameters into the operation mode judgment model to determine whether the operation mode of the drainage pump station is a rainstorm mode or a non-rainstorm mode. The pipeline parameters include rainwater pipe level and rainwater pipe capacity. The pump station parameters include forebay level and regulating tank level. The downstream sewage treatment plant parameters include the inflow rate of the downstream sewage treatment plant.

[0112] The scheduling control module 42 outputs the scheduling arrangement of the drainage pumping station according to the operating mode, until the operation of the drainage pumping station meets the safety requirements.

The downstream sewage treatment plant parameters include the inflow rate of the downstream sewage treatment plant.
