Background Art

[0002] In the treatment of urban black and odorous water bodies, the lack of incoming water during dry or low-rainfall seasons leads to poor river flow and insufficient hydrodynamics. Furthermore, with the expansion of urban development, the water storage area of ​​river networks in built-up areas has decreased, the self-purification function of rivers has degraded, and the river's capacity to absorb pollution is no longer sufficient to meet the erosion of various types of pollution. The water quality of most rivers is consistently rated Class V-Worse V. During hot seasons, some rivers become black and smelly, impacting the urban living environment.

[0003] At present, the current situation of black and odorous water body treatment is poor due to the regional treatment of intercepted river channels and the lack of water supply in dry or rainy seasons, which leads to poor river flow and insufficient water dynamics. Therefore, this problem needs to be solved urgently. Summary of the Invention

[0013] In a possible implementation of the present application, during the low power load phase of the pumped-storage power station, the water treatment room pumps water from the main river channel at the water collection end into the upper storage reservoir through a first water pump; and after the water level of the upper storage reservoir reaches a preset water storage level, the water treatment room pumps water from the main river channel at the water collection end into the lower circulation reservoir for storage through a second water pump.

[0014] In a possible implementation of the present application, during the peak power load phase of the pumped-storage power station, the water in the upper reservoir of the energy storage enters the circulating lower reservoir through a turbine for power generation and flushing, wherein the generated electricity is used to supply power to the various power-consuming parts on the pumped-storage power station side and the smart city equipment side, and during flushing, a third water pump is used to dispatch water resources so that the flushing water from the lower reservoir enters the corresponding river tributary.

[0015] In a possible implementation of the present application, the power calculation formula of the turbine during operation is as follows:

[0016] P=ρ×g×[(Q 上库(流动) +C×p r ×A×k×10 3 )÷28800]×H×η;

[0017] Where P is the turbine power, ρ is the water density, g is the acceleration of gravity, Q 上库(流动) is the flow capacity of the energy storage reservoir, C is the runoff coefficient, p r is the rainfall, A is the basin area, k is the correction coefficient, H is the upstream and downstream water level difference, and η is the turbine efficiency;

[0026] Among them, Q n条流域河道(流动) is the flow capacity of the river, Q n条流域河道总容 is the total capacity of the river, and TR3 is the third ratio threshold.

[0027] In one possible implementation of the present application, remote sensing inversion data of different river tributaries is monitored, and when the remote sensing inversion data exceeds the standard, the river reservoir gate of the corresponding river tributary is opened, specifically including:

[0028] Calculate remote sensing inversion data, the formula is as follows:

[0029]

[0030] Where c(Chla) is the remote sensing inversion data, corresponding to the chlorophyll a concentration, Rrs is the remote sensing reflectance, Chla is chlorophyll a, Rrs490 is the remote sensing reflectance of the 490 nm band, Rrs555 is the remote sensing reflectance of the 555 nm band, and R is the logarithm of the ratio of the remote sensing reflectance of the 490 nm band to the remote sensing reflectance of the 555 nm band.

[0031] When the remote sensing inversion data corresponding to a river channel is greater than or equal to the preset target value and the corresponding chemical oxygen demand concentration exceeds the limit value, the river reservoir gate corresponding to the current river channel is opened, and the flushing water of the circulating lower reservoir enters the river channel for flushing, and when the water capacity of the circulating lower reservoir reaches the target volume, the river reservoir gate is closed.

[0032] In a possible implementation of the present application, the circulating lower reservoir is provided with an industrial spray device, which is used to ensure the water quality of the flushing water in the circulating lower reservoir.

[0054] Smart cities plan cities with smart concepts, build cities in a smart way, manage cities with smart means, and develop cities in a smart way, thereby improving the accessibility of urban space, building an institutional environment and ecology conducive to the emergence of innovation, and achieving sustainable development of cities and regions.

[0055] Pumped storage is a type of energy storage technology that uses water as an energy storage medium to achieve the storage and management of electrical energy through the mutual conversion of electrical energy and potential energy. Electricity is used to pump water to the upper reservoir during low power load periods, and then released to the lower reservoir to generate electricity during peak power load periods, thereby utilizing the excess electricity generated when the grid load is low. The main buildings of a pumped storage power station generally include: an upper reservoir, a lower reservoir, a water transmission system, a plant, and other special buildings. The water level of the reservoir fluctuates greatly and rises and falls frequently. In order to undertake the task of peak-shaving and valley-filling in the power grid, the daily fluctuation of the water level of the pumped storage power station reservoir is usually relatively large, generally exceeding "10 to 20" meters, and some power stations reach "30 to 40" meters. In addition, the rate of change of the reservoir water level is relatively fast, generally reaching "5 to 8" meters / hour, or even "8 to 10" meters / hour. At present, the treatment technologies for black and odorous water bodies are as follows:

[0056] ① Intercepting and pipelining sewage is the most direct and effective engineering measure for the treatment of black and odorous water bodies, and is also the prerequisite for taking other technical measures. It controls the discharge of sewage into urban water bodies at the source.

[0057] ② Dredging is applicable to all black and odorous water bodies, especially those with severe black and odorous water bodies. It can quickly reduce the endogenous pollution load of black and odorous water bodies and prevent the release of sediment pollutants into the water body after the implementation of other treatment measures.

[0058] ③ Live water circulation is to introduce clean water sources upstream or near polluted rivers through the regulation of water conservancy facilities (such as gates and pumping stations) to improve the hydrodynamic conditions of the river and enhance the diffusion, purification and output of pollutants in the water.

[0059] ④ Artificial oxygenation prevents anaerobic decomposition through aeration and accelerates the degradation of organic pollutants in water bodies. Therefore, it can be used as a phased measure to maintain the water quality of urban water bodies after treatment, effectively increase the dissolved oxygen level in local water bodies, and increase regional water mobility.

[0060] ⑤ Clean water replenishment is the use of urban recycled water, urban rainwater, clean surface water, etc. as a supplementary water source for urban water bodies, increasing water body fluidity and environmental capacity.

[0061] ⑥ Bypass treatment involves installing appropriate treatment facilities in the vicinity of a water body. River water is extracted from the most polluted section, purified by the treatment facilities, and then discharged to the other end, achieving water purification and circulation. This method is primarily suitable for purifying severely black and odorous water bodies where comprehensive pollution interception is impossible, or for closed water bodies without external water replenishment. It can also be used for emergency response to sudden black and odorous water incidents.

[0062] Therefore, we can utilize the water system layout to integrate regional water systems, take into account the treatment of black and odorous water bodies, and reduce resource waste at the same time. This type of technology is in great demand, and the smart city water system can be connected and the entire city water system can be extracted to form a "water-energy coupling" system that coordinates water resources and energy.

[0063] Among them, black and smelly rivers generally take "source control and pollution interception, internal source treatment, active water circulation, clean water supply, water quality purification, and ecological restoration" as the main line. In terms of river and lake water circulation, the construction of pumped storage devices in river and lake water systems can be used to regulate the large circulation of urban water systems, and the small circulation of urban water systems can also be regulated. The lower reservoir of the pumped storage power station can be improved to enrich the river while resisting the impact and realize active water circulation.

[0064] When river dredging or sewage treatment is needed for black and odorous water bodies within a water system, water system regulation can be used to retain and transfer water. During dry or low-rainfall seasons, when there is a lack of incoming water, this can address the problems of poor river flow and insufficient hydrodynamics. During water system circulation, source oxygenation can be used to increase dissolved oxygen in the water. This approach, balancing active water circulation, clean water replenishment, and internal water treatment, will form a coordinated approach for pumped storage and black and odorous water treatment in smart city river and lake systems.

[0065] Smart cities can establish river water quality models and transmit real-time water quality signals to solve the problems of blockage or treatment of black and odorous water bodies in a targeted manner. After treating pollution at the source, water can be filled into the river, thereby improving water quality through source treatment.

[0066] Specifically, this application utilizes the working principle of a pumped-storage power station, using electricity during low-load periods to pump water to the upper reservoir, and then releasing water to the main river channel at the catchment end during peak load periods. In terms of use, it is no longer connected to the grid, but rather meets the power supply and source oxygen supply for the control system and the treatment of black and odorous water bodies at the source. In addition, the Rrs value in the chlorophyll formula can be obtained through existing UAV remote sensing or microwave radiometers. However, after comparison, different reservoir and river gate setting logics need to be set according to different remote sensing technologies. As well as the water system of a smart city, it is necessary to more finely control the entire water system. As the "blood vessels" of the city, the water system uses electricity supply to drive river management, which is different from the point-like river management scheme of single channel, single management, setting up fences, setting up sand dams, and dredging regardless of river sections.

[0067] Furthermore, this application is a governance path that combines ecological protection with pumped storage. It overcomes the problems of repeated black and odorous water bodies and blue algae growth caused by point-based governance, and circulates sewage and turns river water into flowing water, forming a large urban circulation. However, it involves the management and control of smart cities. The underlying intelligent logic is different from the digital management of pumped storage power stations. It forms a smart city water circulation model in turbine selection, river flow control, remote sensing and reservoir and river gate control. It can empower the national water conservancy cause through applications such as AI or the Internet of Things.

[0068] The technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention.

[0069] like Figure 1 As shown, in one embodiment of the invention, the smart city river and lake water system pumped storage coordinated black and odorous water treatment system of the present invention includes:

[0070] The pumped storage power station side and the smart city equipment side are connected to the urban river and lake water system; the pumped storage power station side at least includes an upper storage reservoir, a lower circulation reservoir, a water treatment room connected to the main river channel at the water collection end, a river reservoir gate connected to the river tributary, a water pump and a turbine; the smart city equipment side at least includes remote sensing equipment and water quality monitoring instruments set at the river tributary and smart city urban valves connected to the river tributary, wherein,

[0071] The water treatment room pumps water from the main river channel at the water collection end into the energy storage upper reservoir and the circulation lower reservoir through a water pump;

[0072] The energy storage upper reservoir is used to store water, and the turbine is used to generate electricity;

[0073] The circulating lower reservoir is used to flush different river tributaries with stored water when the river reservoir gate is opened;

[0074] The remote sensing equipment is used to monitor remote sensing inversion data of different river tributaries, and the water quality monitoring instrument is used to monitor the chemical oxygen demand of different river tributaries, wherein when both the remote sensing inversion data and the chemical oxygen demand exceed the standard, the river reservoir gate of the corresponding river tributary is opened;

[0075] The smart city urban valve is used to control the direction of flushing water flow in different river tributaries so that all flushing water flows eventually flow into the main river channel at the water collection end.

[0076] It should be noted that, in this embodiment, Figure 1 As shown, the pumped storage power station side connected to the urban river and lake water system includes at least an upper storage reservoir, a lower circulation reservoir, a water treatment room connected to the main river channel at the water collection end, a river reservoir gate connected to the river tributary, a water pump and a turbine; and the smart city equipment side connected to the urban river and lake water system includes remote sensing equipment installed at the river tributary and smart city urban valves connected to the river tributary.

[0077] Specifically, through the control system of an entire pumped storage power station, water is stored during peak and valley periods, and power is generated during peak periods to ensure power balance. At the same time, it can also be connected to the water network of the smart city to control the flushing of different polluted rivers to achieve the goal of coordinated treatment of black and ugly water bodies in the river and lake systems of the smart city through pumped storage. Specifically, the water treatment room uses a water pump to pump water from the main river channel at the confluence end into the energy storage upper reservoir and the circulation lower reservoir. The water pumps include a first water pump and a second water pump. The subsequent instructions will explain in detail the use mechanism of each part of the water pumps. The energy storage upper reservoir is used to store water, and at the same time, the turbine is used to discharge water for power generation, and the circulation lower reservoir is used to use the stored water to flush different river tributaries when the river reservoir gate is opened.

[0078] Furthermore, the remote sensing equipment is used to monitor the remote sensing inversion data of different river tributaries, and the water quality monitor is used to monitor the chemical oxygen demand of different river tributaries, so that the river reservoir gate of the corresponding river tributary can be opened when the remote sensing inversion data and the chemical oxygen demand exceed the standard, so that the flushing water of the circulating lower reservoir can enter the corresponding river for flushing. Furthermore, the smart city urban valve is used to control the flushing water flow direction of different river tributaries, so that all flushing water flows will eventually flow into the main river channel at the water collection end, so that the treatment of black and odorous water bodies remains at the urban water network stage, and the flushing water of the circulating lower reservoir is prevented from entering the county and township water network at the next level of the smart city water network, thereby rationally controlling the scheduling of water resources and improving the intelligent scheduling of smart cities in the field of urban water networks.

[0079] Furthermore, in this embodiment, the water treatment room pumps water from the main river channel at the water confluence end into the upper energy storage reservoir through the first water pump, and the water treatment room pumps water from the main river channel at the water confluence end into the lower circulation reservoir through the second water pump. During the low power load stage of the pumped-storage power station, the water treatment room pumps water from the main river channel at the water confluence end into the upper energy storage reservoir through the first water pump; and after the water level of the upper energy storage reservoir reaches a preset water storage level, the water treatment room pumps water from the main river channel at the water confluence end into the lower circulation reservoir for storage through the second water pump. During the peak power load stage of the pumped-storage power station, the water in the upper reservoir of the upper energy storage reservoir enters the lower circulation reservoir through a turbine for power generation and flushing, wherein the power generated is used to power the various power-consuming parts on the pumped-storage power station side and the smart city equipment side, and during flushing, the third water pump is used to dispatch water resources so that the flushing water from the lower reservoir enters the corresponding river tributary.

[0080] It should be noted that, in this embodiment, Figure 2 As shown, it is a schematic diagram of pumping water in the water treatment room during the peak and valley periods of electricity consumption, wherein, during the low power load phase of the pumped storage power station (corresponding to the peak and valley phase of electricity consumption), the water treatment room is pumped by the first water pump ( Figure 2 The water in the main river channel at the water collection end is pumped into the energy storage upper reservoir, and after the water level of the energy storage upper reservoir reaches the preset water level, the water treatment room is pumped into the energy storage upper reservoir by the second water pump ( Figure 2 The water in the main river channel of the water collection end is pumped into the lower circulation reservoir for water storage, wherein the preset water level of the upper energy storage reservoir is dynamically adjusted according to different seasons, wherein, Figure 3 As shown, it shows a schematic diagram of the pumped storage and coordinated black and odorous water treatment in the river and lake water system of the smart city. In the low power load stage (peak and valley stage of electricity consumption), the water in the main river channel at the catchment end is pumped into the upper storage reservoir and the lower circulation reservoir to wait for water flushing.

[0081] Furthermore, if Figure 4As shown, it is a schematic diagram of pumping water in the water treatment room during the peak power load period. During the peak power load period of the pumped storage power station, the water in the upper reservoir of the energy storage enters the lower circulation reservoir through the turbine to generate electricity and flush. The generated electricity is used to power the various power-consuming parts on the pumped storage power station side and the smart city equipment side. During flushing, the third water pump ( Figure 4 The label ③) in the loop is used to dispatch water resources so that the flushing water of the lower reservoir enters the corresponding river tributary, wherein the power generation is used for electricity consumption of the entire system, including electricity consumption of river (river and lake) aeration equipment, electricity consumption of river (river and lake) gate switch, electricity consumption of river (river and lake) lighting, electricity consumption of river (river and lake) remote sensing equipment, electricity consumption of the central control room and electricity consumption of sewage treatment equipment. Furthermore, if the flushing water level in the circulating lower reservoir is higher than the river to be flushed, there is no need to use the third water pump for dispatching. Specifically, the third water pump is used to dispatch water resources when the river water level is higher than the reservoir water level, so as to flush the current river. Among them, if Figure 5 As shown, it shows a schematic diagram of pumped storage and coordinated black and odorous water body sewage treatment in the river and lake water system of the smart city. In the peak power load stage (peak electricity consumption period), the water in the upper storage reservoir enters the lower circulation reservoir through the turbine to generate electricity, while the flushing water of the lower circulation reservoir enters the corresponding river tributaries through different river gates for flushing.

[0082] Furthermore, in this embodiment, the power calculation formula of the turbine during operation is as follows:

[0083] P=ρ×g×[(Q 上库(流动) +C×p r ×A×k×10 3 )÷28800]×H×η;

[0084] Where P is the turbine power, ρ is the water density, g is the acceleration of gravity, Q 上库(流动) is the flow capacity of the energy storage reservoir, C is the runoff coefficient, p r is the rainfall, A is the basin area, k is the correction coefficient, H is the upstream and downstream water level difference, and η is the turbine efficiency;

[0088] Among them, Q 上库(总) is the total capacity of the energy storage reservoir, Q 上库(流动) is the energy storage upper reservoir flow capacity, TR1 is the first proportional threshold;

[0089] The second condition is the stable operation condition, which specifically includes:

[0093] Among them, Q n条流域河道(流动) is the flow capacity of the river, Q n条流域河道总容 is the total capacity of the river, and TR3 is the third ratio threshold.

[0094] It should be noted that in this embodiment, the power requirements and corresponding capacity requirements of the turbine in the collaborative governance scenario of this application are specifically described. Specifically, the power calculation formula of the turbine during operation is as follows:

[0095] P=ρ×g×[(Q 上库(流动) +C×p r ×A×k×10 3 )÷28800]×H×η;

The purpose is to ensure the stable operation of the entire collaborative treatment system. Furthermore, the flow capacity of the river channel meets the third condition, which corresponds to the scour condition, including:

[0103] Q n条流域河道(流动) :Q n条流域河道总容 =TR3;

[0104] Among them, Q n条流域河道(流动) is the flow capacity of the river, Q n条流域河道总容 is the total capacity of the river channel, TR3 is the third ratio threshold, wherein the third ratio threshold includes "1:(4-6)", the purpose of which is to ensure the flushing effect of the flushing water in the river channel.

[0105] Furthermore, in this embodiment, remote sensing inversion data of different river tributaries are monitored, and when the remote sensing inversion data exceeds the standard, the river reservoir gate of the corresponding river tributary is opened, specifically including:

[0106] Calculate remote sensing inversion data, the formula is as follows:

[0107]

[0108] Where c(Chla) is the remote sensing inversion data, corresponding to the chlorophyll a concentration, Rrs is the remote sensing reflectance, Chla is chlorophyll a, Rrs490 is the remote sensing reflectance of the 490 nm band, Rrs555 is the remote sensing reflectance of the 555 nm band, and R is the logarithm of the ratio of the remote sensing reflectance of the 490 nm band to the remote sensing reflectance of the 555 nm band.

[0109] When the remote sensing inversion data corresponding to a river channel is greater than or equal to the preset target value and the corresponding chemical oxygen demand concentration exceeds the limit value, the river reservoir gate corresponding to the current river channel is opened, and the flushing water of the circulating lower reservoir enters the river channel for flushing, and when the water capacity of the circulating lower reservoir reaches the target volume, the river reservoir gate is closed.

[0110] It should be noted that, in this embodiment, when the value of the remote sensing inversion data c (Chla) of a river channel is greater than or equal to the preset target value and the corresponding chemical oxygen demand concentration exceeds the limit value, the river reservoir gate needs to be opened, wherein the remote sensing inversion data c (Chla) corresponds to the chlorophyll a concentration. In one embodiment, the preset target value is "0.05 mg / L" and the limit value is "35 mg / L". When the remote sensing inversion data c (Chla) ≥ 0.05 and the chemical oxygen demand (COD) concentration exceeds 35 mg / L, the river reservoir gate needs to be opened, and the flushing water in the circulating lower reservoir flows to the polluted rivers for direct flushing. When the effective volume of the circulating lower reservoir is 30% of it, the river reservoir gate is closed, that is, the target volume is "30%".

[0111] Furthermore, in this embodiment, the circulating lower reservoir is provided with an industrial spray device, which is used to ensure the water quality of the flushing water in the circulating lower reservoir. The river tributaries are provided with river aeration devices, which are used to degrade organic matter. The river tributaries are also provided with anti-backflow valves, which are used to prevent the backflow of flushing water.

[0112] It should be noted that, in this embodiment, the industrial spray device described can operate 24 hours a day to ensure the water quality of the water in the circulating lower reservoir, wherein the mist is stored above the circulating lower reservoir at night, so that the circulating lower reservoir reduces the growth of algae, thereby keeping the flushing water clean, and further ensuring the flushing effect. Of course, in actual application, the lower outlet and the tailwater tunnel can also be designed with a reverse slope, and the bottom flow energy dissipation method can be used to buffer the drainage impact, and the water mist above the circulating reservoir can also be enhanced to reduce the growth of algae; further, a river aeration device is also provided at the river tributary, which corresponds to an oxygenation device, which is used to degrade organic matter in the black and odorous water body in time to reduce the black and odorous water body. At the same time, to ensure that the flushing water does not flow back, an anti-backflow valve is also provided at the river tributary to avoid the backflow of the flushing water, so that all the flushing water flows can eventually flow into the main river channel at the water collection end under the joint action of the smart city urban valves.

[0144] Further, see Figure 7 The present application provides a method for treating black and odorous water bodies in smart city river and lake water systems by pumped storage and coordinated operation, which is applied to the above-mentioned device for treating black and odorous water bodies in smart city river and lake water systems by pumped storage and coordinated operation. The method specifically includes the following steps:

[0145] Step S702: During a low power load phase of the pumped storage power station, water from the main river channel at the water collection end is pumped into the upper storage reservoir by a first water pump based on the water treatment room, and water from the main river channel at the water collection end is pumped into the lower circulation reservoir by a second water pump;

[0146] Step S704: During the peak power load phase of the pumped storage power station, water in the upper reservoir of the energy storage enters the lower circulation reservoir through a turbine to generate electricity and flush water;

[0147] Step S706: Powering different electrical devices based on the power generated by the water in the upper reservoir entering the circulating lower reservoir through the turbine, wherein the electrical devices at least include a river gate switch and a river aeration device located at a river tributary;

[0148] Step S708: Acquire remote sensing inversion data and chemical oxygen demand of different river channels to determine the target river channel to be flushed, and when the river gate switch is opened to flush the corresponding target river channel, control the river aeration device to perform oxygenation operations, and control the opening and closing of the preset smart city urban valves to determine the flushing water flow direction of different river tributaries.

[0149] It should be noted that, in this embodiment, this method realizes the corresponding logical topology control through the physical topology network at the physical level, wherein the various components (devices) in the physical topology network at the physical level have been described in the various embodiments of the smart city river and lake water system pumped storage and coordinated black and odorous water body treatment system in the above embodiments, and this application will explain in detail the execution method at the logical control level, wherein, first, according to the different power load stages of the pumped storage power station, the working modes of the upper storage reservoir and the lower circulation reservoir are controlled, wherein, in the low power load stage of the pumped storage power station, the water in the main river channel of the water confluence end is pumped into the upper storage reservoir through the first water pump based on the water treatment room, and the water in the main river channel of the water confluence end is pumped into the lower circulation reservoir through the second water pump; and in the peak power load stage of the pumped storage power station, the upper reservoir water in the upper storage reservoir enters the lower circulation reservoir through the turbine for power generation and flushing.

[0150] Furthermore, when generating electricity, different power-consuming devices are powered based on the power generated by the water in the upper reservoir entering the lower reservoir of the circulation through the turbine. The power-consuming devices at least include river gate switches and river aeration devices located at the river tributaries, as well as water quality remote sensing equipment and water quality monitoring instruments set at the river tributaries and industrial spray devices set at the lower reservoir of the circulation, etc., which require electricity. At the same time, when flushing, the target river channel to be flushed is determined by obtaining remote sensing inversion data and chemical oxygen demand of different river channels. How to determine the target river channel The channel is specifically based on the comparison between the remote sensing inversion data and the preset target value, as well as the chemical oxygen demand and the limit value. The details will not be repeated here. After the target river channel is determined, the corresponding river gate switch is opened to flush the target river channel, and the river aeration device is controlled to perform oxygenation during flushing to reduce the organic matter in the black and odorous water body. At the same time, the opening and closing of the preset smart city urban valves are controlled to determine the flushing water flow direction of different river tributaries, so that all flushing water flows will eventually flow into the main river channel at the catchment end corresponding to the urban water network of the current smart city.
