Description

Technical Field

[0001] This invention relates to the field of water pollution monitoring technology, and in particular to a water pollution early warning system and method, electronic equipment, and storage medium. Background Technology

[0002] Human survival and industrial production activities are mostly concentrated in sea and river basins. The processes of living and production continuously pollute the aquatic environment, and the prevention and treatment of pollution in the aquatic ecological environment has always been an urgent problem to be solved.

[0003] Currently, the basic items in water environmental quality standards for relevant technologies include: temperature, pH, dissolved oxygen, permanganate, chemical oxygen demand (COD), biochemical oxygen demand (BOD), ammonia nitrogen, total phosphorus, total nitrogen, heavy metals, sulfides, etc. Monitoring each parameter requires specific sensors (chemical methods, optical methods) for quantitative measurement. The water quality is then determined by comparing the content requirements of each parameter with those in the standards. For example, a multi-parameter water quality instrument is typically used to measure parameters such as chlorophyll, dissolved oxygen, soluble organic carbon, oil in water, and nitrogen oxides at different locations. Each parameter requires a specific sensor for measurement. By recording the results of each parameter, it is determined whether the content of each parameter in the water body is normal and whether pollution exists.

[0004] However, due to the different pollution sources and types of pollutants in different river basins, it is impossible to make a judgment using only one or a few specific sensors. At the same time, the high unit price and large variety of sensors make it impossible to deploy them in all river basins, thus limiting the development of water ecological environment quality monitoring. Summary of the Invention

[0005] This invention provides a water pollution early warning system and method, electronic device, and storage medium to address the shortcomings of related technologies that use multiple specific sensors to monitor specific parameters in water bodies, which are inconvenient to use due to the large number of parameters to be monitored. The solution in this application uses the changes in electrical signals from cathode and anode sensors to characterize changes in water environmental parameters, thereby achieving more accurate and efficient monitoring of water pollution.

[0006] This invention provides a water pollution early warning system, comprising: A cathode sensor array is placed in the water body of the water to be monitored and is used to generate electrical signals when the environmental parameters of the water body change. An anode sensor array is placed in the sediment at the bottom of the water body to be monitored, and is used to generate electrical signals when the environmental parameters of the sediment change. The server is configured to, upon receiving the electrical signal generated by the cathode sensor array and / or the electrical signal from the anode sensor array, compare the electrical signal with a pre-constructed first correspondence to determine the water pollution status of the water area to be monitored and issue an early warning, wherein the first correspondence is the correspondence between the electrical signal and the water pollution.

[0007] The water pollution early warning system provided by the present invention also includes a wireless communication module; The wireless communication module is electrically connected to the cathode sensor array and the anode sensor array, and is used to send the electrical signals generated by the cathode sensor array and / or the anode sensor array to the server.

[0010] According to the water pollution early warning system provided by the present invention, the cathode sensor array includes a plurality of cathode sensors, the anode sensor array includes a plurality of anode sensors, and the plurality of cathode sensors and the plurality of anode sensors are respectively disposed at different locations in the water area to be detected; The server is also used to trace the source of pollutants based on the differences in the electrical signals of the cathode sensors and the anode sensors.

[0011] In the water pollution early warning system provided by the present invention, the cathode sensor and the anode sensor are made of carbon materials.

[0012] The present invention also provides a water pollution early warning method, applied to any of the above-mentioned water pollution early warning systems, comprising: The system receives electrical signals generated by a plurality of cathode sensors and / or a plurality of anode sensors when environmental parameters of the water body to be monitored change, wherein the cathode sensors and the anode sensors are disposed in the water body to be monitored; The electrical signal is compared with a pre-constructed first correspondence to determine the water pollution status of the water area to be monitored and to issue an early warning.

[0016] The present invention also provides a computer program product, including a computer program that, when executed by a processor, implements any of the above-described water pollution early warning methods.

[0017] The water pollution early warning system provided by this invention includes a cathode sensor array and an anode sensor array, respectively positioned at different locations within the water body to be monitored. The cathode sensor array is located in the water body, primarily monitoring water-related environmental parameters such as temperature, dissolved oxygen, and heavy metal particles. It generates electrical signals when these environmental parameters change. The anode sensor array is located in the sediment at the bottom of the water body, monitoring sediment-related environmental parameters such as organic matter content, water content, and nitrogen compound content.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0022] Figure 1 This is one of the structural schematic diagrams of the water pollution early warning system provided in the embodiments of the present invention.

[0023] like Figure 1 As shown, this embodiment provides a water pollution early warning system, including: A cathode sensor array 1 is disposed in the water body of the water body to be monitored, and is used to generate an electrical signal when the environmental parameters of the water body change. Anode sensor array 2 is disposed in the sediment at the bottom of the water body to be monitored, and is used to generate electrical signals when the environmental parameters of the sediment change; The server is configured to, upon receiving the electrical signal generated by the cathode sensor array and / or the electrical signal from the anode sensor array, compare the electrical signal with a pre-constructed first correspondence to determine the water pollution status of the water area to be monitored and issue an early warning, wherein the first correspondence is the correspondence between the electrical signal and the water pollution.

[0024] In practical applications, cathode sensor arrays can be made of carbon materials, with the shaped electrodes completely immersed in water. The aquatic ecological environment is monitored by utilizing the reduction reactions of dissolved oxygen and other electron acceptors on the carbon cathode. Anode sensor arrays can also be made of carbon materials, with the shaped electrodes buried in mud. The pollution level in the sediment is monitored by utilizing the oxidation reaction process where electrons generated by electrogenic microorganisms metabolizing organic matter migrate to the electrode surface.

[0025] The cathode sensor array can be used to measure pollution in water bodies. By setting up multiple layers from the bottom to the surface, it can achieve multi-layer measurement within the water depth profile. The anode sensor array can be used to measure pollution in sediments. The electrical signals generated by the cathode and anode sensor arrays can include data such as output voltage, output current, and potential. This data can be sent to a server. The server runs front-end software. After receiving, saving, and processing the relevant data, the software makes a judgment on the pollution situation and sends alarm information in a timely manner to determine the location of pollution when pollution occurs.

[0026] The electrode potential of the cathode sensor array is sensitive to water temperature, dissolved oxygen, soluble organic matter (DOM), phytoplankton, and heavy metal particles; the electrode potential of the anode sensor array is sensitive to organic matter, water content, nitrogen compounds, and heavy metals in sediments. The server can perform real-time data comparison. When parameters in the water and sediments change, the voltage, output current, and electrode potential of both the cathode and anode sensor arrays will change. By comparing these parameters with a pre-built first correspondence in the server, it can determine whether pollution has occurred in the water and sediments, thus issuing real-time alarm information. In practice, the first correspondence can include model curves such as dissolved oxygen model curves, soluble organic carbon model curves, and heavy metal pollution model curves. For example, the dissolved oxygen model curve can be the correspondence between changes in dissolved oxygen parameters in the water and the generated electrical signal, which can be obtained through pre-calibration. In practice, during calibration, the specific content of dissolved oxygen parameters can be disregarded; only the changes in dissolved oxygen can be considered. For example, the correspondence between changes in dissolved oxygen parameters and electrical signals can be calibrated.

[0027] In this embodiment, a wireless communication module 5 is also included; The wireless communication module is electrically connected to the cathode sensor array and the anode sensor array, and is used to send the electrical signals generated by the cathode sensor array and / or the anode sensor array to the server.

[0028] In practical applications, after the cathode sensor array and anode sensor array generate electrical signals based on changes in environmental parameters, the electrical signals can be acquired by the data acquisition module 3 and then sent to the wireless communication module.

[0029] In the embodiments, the cathode sensor array and the anode sensor array are further used for: The electrical signals generated by the application power the wireless communication module.

[0030] In this embodiment, a solar power supply module 4 is also included; The solar power module is electrically connected to the wireless communication module and is used to supply power to the wireless communication module.

[0031] Figure 2 This is the second structural schematic diagram of the water pollution early warning system provided in the embodiments of the present invention.

[0032] like Figure 2 As shown, the water pollution early warning system provided in this application can be deployed at multiple points along a river channel, forming a three-dimensional network for measurement, thereby achieving continuous monitoring across the entire basin, multiple water depth profiles, on a large scale, and at low cost. At different locations along the main stream or tributary of a river, or at different points along a large lake, the real-time alarm system is deployed at certain intervals (2km, 10km, or 20km, etc.) or at key locations (village residential areas, factory clusters, etc.). It collects voltage, output current, and electrode potential data at each point in real time and transmits all data to a remote server via a wireless communication module. The front-end software receives, saves, and processes the data in real time, and issues an alarm when a significant change occurs at a particular point, promptly identifying pollution at that point. Subsequently, the pollution source can be determined based on the pollution status of other points deployed along the same river channel. For example, if a point is polluted but its upstream point is not, the pollution source may be between the two points; if the entire river channel is polluted, the pollution source may be located in the upstream channel.

[0033] In summary, the water pollution early warning system provided in this application has the following beneficial effects: 1. Array deployment, multi-point, multi-layer measurement, and network monitoring. In-situ electrochemical sensors are fabricated using microbial electrochemical technology. By deploying an array of electrochemical sensors at specific intervals in the target water area, continuous real-time monitoring of the water depth profile and the entire watershed is achieved. Alarm information is promptly issued upon detection of suspicious changes.

[0034] 2. Unique sensor design for simultaneous monitoring of water and sediment. The cathode sensor array is immersed in the water to monitor aquatic environmental pollution, while the anode sensor array is buried in the sediment to monitor sediment environmental pollution.

[0035] 3. It can generate electricity in situ and use it to drive system operation. While generating and transmitting electrical signals, the cathode sensor array and anode sensor array also have the ability to generate electricity in situ, which can provide power to other components in the system.

[0036] 4. It has early warning and countermeasure functions. As a means of treating pollutants in situ, the water pollution early warning system integrates monitoring, alarm, source tracing and in-situ treatment capabilities. It can not only detect pollution, but also treat pollutants and accelerate their degradation.

[0037] 5. Applicable to monitoring various water environment parameters, with high versatility. Both cathode and anode sensors respond to multiple parameters and can be used in different types of water environments, eliminating the need for numerous quantitative sensors, thus saving costs and improving efficiency.

[0038] 6. Continuous monitoring, unattended operation, real-time monitoring, strong targeting, and high traceability efficiency.

[0039] The water pollution early warning method provided by the present invention is described below. The water pollution early warning method described below can be referred to in correspondence with the water pollution early warning system described above.

[0040] Figure 3 This is a flowchart illustrating the water pollution early warning method provided in this embodiment of the invention.

[0041] like Figure 3 As shown, water pollution early warning methods include: Step 301: Receive electrical signals generated by a plurality of cathode sensors and / or a plurality of anode sensors when environmental parameters of the water area to be monitored change, wherein the cathode sensors and the anode sensors are disposed in the water area to be monitored; Step 302: Compare the electrical signal with a pre-constructed first correspondence to determine the water pollution status of the water area to be monitored and issue an early warning. The first correspondence is the correspondence between the electrical signal and the water pollution.

[0042] In an exemplary embodiment, it also includes: The source of pollutants is traced based on the differences in the electrical signals of the various cathode sensors and anode sensors.

[0043] Figure 4 An example is a schematic diagram of the physical structure of an electronic device, such as... Figure 4As shown, the electronic device may include: a processor 410, a communication interface 420, a memory 430, and a communication bus 440, wherein the processor 410, the communication interface 420, and the memory 430 communicate with each other via the communication bus 440. The processor 410 can call logical instructions in the memory 430 to execute a water pollution early warning method, which includes: The system receives electrical signals generated by a plurality of cathode sensors and / or a plurality of anode sensors when environmental parameters of the water body to be monitored change, wherein the cathode sensors and the anode sensors are disposed in the water body to be monitored; The electrical signal is compared with a pre-constructed first correspondence to determine the water pollution status of the water area to be monitored and to issue an early warning. The first correspondence is the correspondence between the electrical signal and the water pollution.

[0044] Furthermore, the logical instructions in the aforementioned memory 430 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, essentially, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product. This computer software product is stored in a storage medium and includes several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) to execute all or part of the steps of the methods of the various embodiments of the present invention. The aforementioned storage medium includes various media capable of storing program code, such as USB flash drives, portable hard drives, read-only memory (ROM), random access memory (RAM), magnetic disks, or optical disks.

[0045] On the other hand, the present invention also provides a computer program product, which includes a computer program that can be stored on a non-transitory computer-readable storage medium. When the computer program is executed by a processor, the computer is able to execute the water pollution early warning method provided by the above methods, the method including: The system receives electrical signals generated by a plurality of cathode sensors and / or a plurality of anode sensors when environmental parameters of the water body to be monitored change, wherein the cathode sensors and the anode sensors are disposed in the water body to be monitored; The electrical signal is compared with a pre-constructed first correspondence to determine the water pollution status of the water area to be monitored and to issue an early warning. The first correspondence is the correspondence between the electrical signal and the water pollution.

[0046] The following examples illustrate the specific application scenarios and implementation methods of the water pollution early warning system and method provided in this application: Example 1: The Yangtze River basin covers a vast area, passes through numerous towns, and has well-developed waterways, posing a potential pollution risk. Sixty real-time alarm systems were deployed along the river at fixed intervals of 100 km to continuously record the voltage (U1, U2, U3...), current (I1, I2, I3...), and electrode potential (φ1, φ2, φ3...) at each point. Based on existing dissolved oxygen model curves, soluble organic carbon model curves, and on-site calibration data, alarm threshold curves for different points were established. In the event of significant changes in voltage, current, and electrode potential at point 65, an alarm message for point 65 was promptly issued, notifying relevant personnel to conduct quantitative observations of dissolved oxygen and soluble organic carbon at point 65, promptly determining the pollution situation, and, combined with conditions near point 65, identifying the source of pollution.

[0047] Example 2: The Yellow River basin covers a vast area and passes through numerous towns, posing a potential risk of pollution from domestic sewage. Thirty real-time alarm systems have been deployed in key areas along the river to continuously record voltage (U1, U2, U3...), current (I1, I2, I3...), and electrode potential (φ1, φ2, φ3...) at each location. Based on existing dissolved oxygen model curves, soluble organic carbon model curves, and on-site calibration data, alarm threshold curves for different locations have been established. In the event of significant changes in voltage, current, and electrode potential at location 12, an alarm message for location 12 will be promptly issued, notifying relevant personnel to conduct quantitative observations of dissolved oxygen and soluble organic carbon at location 12. This will allow for timely determination of the pollution situation and, combined with conditions in the vicinity of location 12, identification of the pollution source.

[0048] Example 3: A real-time alarm system was deployed at a tributary in the river's estuary. Due to the low flow velocity and poor mass exchange in this area, coupled with continuous input of domestic sewage, the water body became eutrophic, causing a sharp drop in dissolved oxygen. This resulted in a decrease in the cathode sensor reading φcat, while the anode sensor reading φan remained stable, leading to a decrease in both output voltage U and output current I. Based on a numerical fitting model under normal conditions and on-site calibration data, alarm information was promptly issued, notifying relevant personnel in the watershed to handle the situation on-site. Simultaneously, stored electrical energy was output in pulse form to electrolyze the water to produce oxygen and hydrogen, serving as a countermeasure to increase the dissolved oxygen content of the water body.

[0049] Example 4: A livestock and poultry farm has the ability to treat sewage, and the treated sewage can be discharged after meeting the standards. In order to monitor whether the water body at the sewage outlet meets the standards, a real-time alarm system can be installed. When the sewage is discharged without meeting the standards, the amount of antibiotics in the water body increases, and the cathode sensor and anode sensor respond. The electrode potentials φcat and φan of the positive and negative electrodes change, and the current output I decreases, sending out a potential warning. The relevant responsible personnel in the basin conduct quantitative observations on specific sensors to determine that the pollutant is antibiotics, notify the enterprise responsible person to maintain the sewage treatment system, and at the same time accelerate the treatment of antibiotics in the water body.

[0050] Example 5: There are a large number of individual aquaculture households near a certain basin. During the aquaculture process, they often overuse feed and bactericidal drugs, and there is also a phenomenon of secretly discharging sewage during the water change process of the pond. A number of real-time alarm systems are continuously installed upstream, downstream of the basin and near the aquaculture households. When there is a phenomenon of secretly discharging sewage and sludge, the organic matter content in the bottom mud continues to increase, and the cathode sensor and anode sensor respond. The electrode potentials φcat and φan of the positive and negative electrodes change, and the current output I increases, sending out a potential warning. The relevant responsible personnel in the basin conduct quantitative observations on specific sensors to determine that the pollutant is aquaculture sludge containing excessive bait, notify the aquaculture farmers to make rectifications, and make corresponding compensation claims and penalties.

[0051] Example 6: There are multiple industrial areas near a certain basin, and the treated sewage can be discharged after meeting the standards. In order to monitor whether the water body at the sewage outlet meets the standards, multiple real-time alarm systems can be installed. When the heavy metal ions in the water body increase, the cathode sensor and anode sensor respond. The electrode potentials φcat and φan of the positive and negative electrodes change, and the current output I decreases, sending out a potential warning. The relevant responsible personnel in the basin conduct quantitative observations on specific sensors to determine that the pollutant is the excessive content of heavy metal particles, notify the enterprise responsible person to maintain the sewage treatment system, and make corresponding compensation claims and penalties.

[0052] Example 7: In a certain port area, there are many navigable vessels, and there is a risk of oil leakage, resulting in an increase in the oil content in the water. When the oil content in the water body increases, the cathode sensor and anode sensor respond. The electrode potentials φcat and φan of the positive and negative electrodes change, and the current output I increases, sending out a potential warning. The relevant responsible personnel in the port conduct quantitative observations on specific sensors to determine that the pollutant is the excessive oil content in the water, notify the relevant vessel personnel to maintain, and make corresponding compensation claims and penalties.

[0053] In another aspect, the present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, is implemented to perform the water pollution early warning method provided by the above methods, the method comprising: The system receives electrical signals generated by a plurality of cathode sensors and / or a plurality of anode sensors when environmental parameters of the water body to be monitored change, wherein the cathode sensors and the anode sensors are disposed in the water body to be monitored; The electrical signal is compared with a pre-constructed first correspondence to determine the water pollution status of the water area to be monitored and to issue an early warning. The first correspondence is the correspondence between the electrical signal and the water pollution.

[0054] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0055] Through the above description of the embodiments, those skilled in the art can clearly understand that each embodiment can be implemented by means of software plus necessary general-purpose hardware platforms, and of course, it can also be implemented by hardware. Based on this understanding, the above technical solutions, in essence or the part that contributes to the prior art, can be embodied in the form of a software product.
