Description

Technical Field

[0001] This invention relates to the field of water environment management and ecological restoration technology, specifically to a device and method for improving water transparency based on an intelligent linkage dosing system. Background Technology

[0002] Lakes, reservoirs, and other freshwater bodies are important carriers of regional water resource supply and ecological services. However, due to the influence of watershed inflow, wind and wave disturbance, and eutrophication, the phenomenon of reduced transparency is common. The main reasons include: a large number of suspended particles (sediment, colloids, organic debris, etc.) entering the water body, excessive algal blooms, and the combined effects of suspended solids and algae.

[0003] Water transparency improvement measures can remove suspended solids and algae by manually or periodically adding flocculants and precipitants. However, these methods have a single addition mode, low level of intelligence, lack on-demand adjustment, and are prone to waste of chemicals or ecological side effects, thus failing to effectively improve water transparency. Summary of the Invention

[0004] This invention provides a water transparency enhancement device and method based on an intelligent linkage dosing system to solve the problem that related water transparency enhancement measures have low intelligence levels and cannot effectively improve water transparency.

[0005] In a first aspect, the present invention provides a water transparency enhancement device based on an intelligent linkage dosing system, the device comprising:

[0006] The system includes a water transparency sensor, a suspended solids concentration sensor, a chlorophyll a sensor, a data acquisition and discrimination module, a pesticide dosing control module, a pesticide storage and dosing module, and a pesticide spraying module. The water transparency sensor, suspended solids concentration sensor, and chlorophyll a sensor are installed in the target water body. The data acquisition and discrimination module is connected to the water transparency sensor, suspended solids concentration sensor, and chlorophyll a sensor respectively. The pesticide dosing control module is connected to both the data acquisition and discrimination module and the pesticide storage and dosing module. The pesticide storage and dosing module is connected to the pesticide spraying module.

[0007] This invention provides a water transparency enhancement device based on an intelligent linkage dosing system. It monitors water transparency, suspended solids concentration, and chlorophyll a concentration in real time through multiple sensors. The data acquisition and discrimination module determines the cause of the decrease in the transparency of the target water body. Then, the dosing control module drives the dosing module and the spraying module to dosing the dosing. This constructs a closed-loop linkage system for real-time transparency monitoring, intelligent cause determination, and dosing control, realizing intelligent, precise, and ecological control of water transparency enhancement.

[0008] In one optional implementation, the drug storage and dosing module includes:

[0009] Multiple drug storage chambers, each equipped with a drug outlet, valve, dosage control equipment, and drug delivery pipeline; the drug outlet is connected to the drug spraying module.

[0010] In one optional embodiment, multiple drug storage chambers respectively store a rapid sedimentation agent for suspended solids, a compound agent, and an algae removal agent.

[0011] Secondly, this invention provides a method for improving water transparency based on an intelligent linkage dosing system, applied to a data acquisition and discrimination module in a water transparency improvement device based on an intelligent linkage dosing system according to the first aspect or any corresponding embodiment. The method includes:

[0012] The system acquires the water transparency, suspended solids concentration, and chlorophyll a concentration of the target water body within a preset monitoring time period. Water transparency is obtained from a water transparency sensor; suspended solids concentration is obtained from a suspended solids concentration sensor; and chlorophyll a concentration is obtained from a chlorophyll a sensor.

[0013] Water transparency, suspended solids concentration, and chlorophyll a concentration were compared with preset thresholds.

[0014] Based on the comparison results, the control module for drug storage and dosing and the drug spraying module add drugs to the target water body.

[0015] This invention provides a method for improving water transparency based on an intelligent linkage dosing system. It uses multiple sensors to monitor water transparency, suspended solids concentration, and chlorophyll a concentration in real time. These parameters are compared with preset thresholds. Based on the comparison results, chemicals are added to the target water body. The system intelligently distinguishes whether the decrease in transparency is caused by suspended particles, algae, or both, and adds rapid sedimentation agents for suspended solids, algae removal agents, or compound agents as needed. A logic for determining the cause of the decrease in transparency is established, differentiating the contribution of suspended solids from algae, thus achieving intelligent and automated improvement of water transparency.

[0016] In one optional implementation, the agent storage and dosing module and the agent spraying module are controlled to add agents to the target water body based on comparison results, including:

[0017] If the water transparency is less than the transparency threshold, the suspended solids concentration is compared with the first concentration threshold, and the chlorophyll a concentration is compared with the second concentration threshold.

[0018] If the suspended solids concentration is greater than or equal to the first concentration threshold, or the chlorophyll a concentration is greater than or equal to the second concentration threshold, the agent dosing control module delivers the agent to the agent spraying module and drives the agent spraying module to spray the agent onto the target water body.

[0019] This invention provides a method for improving water transparency based on an intelligent linkage dosing system. It establishes a logic for judging the causes of decreased transparency, distinguishes the contribution of suspended solids and algae, and intelligently distinguishes whether the decrease in transparency is caused by suspended particles, algae, or both based on monitoring data. Then, it adds the corresponding functional flocculants or agents as needed to accurately improve water transparency, thus realizing intelligent, precise, and ecological control of water transparency improvement.

[0020] In one optional implementation, if the suspended solids concentration is greater than or equal to a first concentration threshold, or the chlorophyll a concentration is greater than or equal to a second concentration threshold, the agent dosing control module is controlled to deliver the agent to the agent spraying module and drive the agent spraying module to spray the agent onto the target water body, including:

[0021] If the suspended solids concentration is greater than or equal to the first concentration threshold and the chlorophyll a concentration is less than the second concentration threshold, a first dosing control command is sent to the agent dosing control module. The first dosing control command is used to control the agent storage and dosing module to deliver the suspended solids rapid settling agent to the agent spraying module and drive the agent spraying module to spray the suspended solids rapid settling agent onto the target water body.

[0022] In one optional implementation, if the suspended solids concentration is greater than or equal to a first concentration threshold, or the chlorophyll a concentration is greater than or equal to a second concentration threshold, the agent dosing control module is controlled to deliver the agent to the agent spraying module, and the agent spraying module is driven to spray the agent onto the target water body, including:

[0023] If the suspended solids concentration is less than the first concentration threshold and the chlorophyll a concentration is greater than or equal to the second concentration threshold, a second dosing control command is sent to the agent dosing control module. The second dosing control command is used to control the agent storage and dosing module to deliver algae remover to the agent spraying module and drive the agent spraying module to spray algae remover onto the target water body.

[0024] In one optional implementation, if the suspended solids concentration is greater than or equal to a first concentration threshold, or the chlorophyll a concentration is greater than or equal to a second concentration threshold, the agent dosing control module is controlled to deliver the agent to the agent spraying module, and the agent spraying module is driven to spray the agent onto the target water body, including:

[0025] If the suspended solids concentration is greater than or equal to the first concentration threshold and the chlorophyll a concentration is greater than or equal to the second concentration threshold, a third dosing control command is sent to the agent dosing control module. The third dosing control command is used to control the agent storage and dosing module to deliver the compound agent to the agent spraying module and drive the agent spraying module to spray the compound agent onto the target water body.

[0026] In an optional implementation, before comparing the suspended solids concentration with a first concentration threshold and the chlorophyll a concentration with a second concentration threshold if the water transparency is less than a transparency threshold, the method further includes:

[0027] Based on the transparency threshold, the first concentration threshold and the second concentration threshold are determined by utilizing the mapping relationship between transparency and suspended matter concentration and chlorophyll a concentration, respectively.

[0028] This invention provides a method for improving water transparency based on an intelligent linkage dosing system. It utilizes the mapping relationship between transparency and suspended solids concentration and chlorophyll a concentration to determine a first concentration threshold and a second concentration threshold, respectively. By using the transparency threshold, the first concentration threshold, and the second concentration threshold, it is possible to accurately distinguish whether suspended solids or algae are the dominant factors, and select and add appropriate functional agents as needed.

[0029] In one alternative implementation, it further includes:

[0030] Delayed monitoring is performed on the target water body after the addition of the agent to obtain multiple water body transparency values ​​within the delayed monitoring period, and the agent dosage is adjusted based on the multiple water body transparency values.

[0031] This invention provides a method for improving water transparency based on an intelligent linkage dosing system. By performing delayed monitoring of the target water body after the addition of chemicals, and adjusting the dosage of chemicals based on the transparency detection values ​​of multiple water bodies within the delayed monitoring period, the method achieves delayed monitoring of the target water body and feedback adjustment of the dosage of chemicals, forming a closed-loop control of "monitoring-discrimination-addition-feedback", which ensures the closed-loop operation of the water transparency improvement device based on the intelligent linkage dosing system.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.

[0040] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] Water transparency improvement measures can be implemented by manually or periodically adding flocculants and precipitants to remove suspended solids and algae.

[0042] However, the aforementioned methods have a single application mode, lack on-demand adjustment, and are prone to waste of reagents or ecological side effects. They also cannot distinguish in real time the main cause of the decrease in transparency (suspended particles or algae), and the application and sensor monitoring do not achieve closed-loop linkage control, resulting in unstable treatment effects. Therefore, there is an urgent need for a new device and method to improve transparency that can combine multi-source sensor monitoring, intelligent identification, and precise application.

[0043] This invention provides a method for improving water transparency based on an intelligent linkage dosing system. The method is applied to a water transparency improvement device based on the intelligent linkage dosing system. It uses a sensor network to monitor transparency, suspended solids concentration, and chlorophyll a concentration in real time; establishes a logic to determine the causes of transparency decline, distinguishing between the contributions of suspended solids and algae; adds appropriate functionalized flocculants or agents as needed to precisely improve water transparency; and ensures the device can operate in a closed loop, achieving "dosing only when needed."

[0044] This embodiment provides a water transparency enhancement device based on an intelligent linkage dosing system. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0045] This embodiment provides a water transparency enhancement device based on an intelligent linkage dosing system, such as... Figure 1 As shown, it includes:

[0046] The system includes a water transparency sensor 101, a suspended solids concentration sensor 102, a chlorophyll a sensor 103, a data acquisition and discrimination module 104, a pesticide dosing control module 105, a pesticide storage and dosing module 106, and a pesticide spraying module 107. The water transparency sensor 101, suspended solids concentration sensor 102, and chlorophyll a sensor 103 are installed within the target water body. The data acquisition and discrimination module 104 is connected to the water transparency sensor 101, suspended solids concentration sensor 102, and chlorophyll a sensor 103, respectively. The pesticide dosing control module 105 is connected to the data acquisition and discrimination module 104 and the pesticide storage and dosing module 106, respectively. The pesticide storage and dosing module 106 is connected to the pesticide spraying module 107.

[0047] Specifically, such as Figure 1 As shown, the water transparency sensor 101, suspended solids concentration sensor 102, and chlorophyll a sensor 103 are all installed in the target water body. They are usually deployed by means of floating buoys, self-supporting brackets, or cable suspension, so that the sensor probes are located in the depth range of 0.3~1.0m.

[0048] Furthermore, the data acquisition and discrimination module 104 is connected to three types of sensors (i.e., water transparency sensor 101, suspended solids concentration sensor 102, and chlorophyll a sensor 103) via wired connection to receive real-time monitoring data.

[0049] Furthermore, the installation method of the drug dosing control module 105 is not limited, as long as it can effectively transmit signals; the drug dosing control module 105 and the data acquisition and discrimination module 104 interact with each other via wireless communication or local area network; the drug dosing control module 105 and the drug dosing storage and dosing module are connected by wired power supply + control signal line or wireless relay control method.

[0050] Furthermore, the agent addition and storage module and the agent spraying module 107 are integrated and connected by a drug delivery pipeline. This integrated device can be installed on a floating platform on the water surface or at a spraying point on the shore, but the nozzle must be facing the surface area of ​​the target water body. The agent storage and addition module 106 and the agent spraying module 107 are connected by three independent drug delivery pipelines, wired circuits and signal lines, corresponding to three types of agents, which can be powder or solution.

[0051] This embodiment provides a water transparency enhancement device based on an intelligent linkage dosing system. It monitors water transparency, suspended solids concentration, and chlorophyll a concentration in real time through multiple sensors. The data acquisition and discrimination module determines the cause of the decrease in the target water transparency. Then, the dosing control module drives the dosing storage and dosing module and the spraying module to dosing the dosing. This constructs a closed-loop linkage system for real-time transparency monitoring, intelligent cause determination, and dosing control, realizing intelligent, precise, and ecological control of water transparency enhancement.

[0052] In some optional embodiments, the drug storage and dosing module 106 includes:

[0053] Multiple drug storage chambers 1061 are provided, each of which is equipped with a drug outlet 1062, a valve and dosage control device 1063 and a drug delivery pipeline 1064; the drug outlet 1062 is connected to the drug spraying module 107.

[0054] Specifically, the valve and dosage control device 1063 are driven by the drug dosing control module 105, such as... Figure 1 As shown, the drug storage chamber 1061 can be set to 3, or it can be increased or decreased according to actual needs.

[0055] Furthermore, the drug storage and dosing module 106 is internally designed with three completely independent drug storage chambers 1061. Each chamber is equipped with an independent drug outlet 1062, valves and dosage control devices 1063 (including metering pumps and solenoid valves), and drug delivery pipelines 1064. When the drug is added, the drug dosing control module 105 only opens the pipeline of the corresponding chamber and keeps the other two closed to ensure that only the required drug is added.

[0056] In some alternative embodiments, multiple drug storage chambers 1061 respectively store a rapid sedimentation agent for suspended solids A, a compound agent B, and an algae removal agent C.

[0057] Specifically, the functionalized agents stored in the drug storage chamber 1061 include three types: rapid sedimentation agent A, algae removal agent C, and compound agent B. Their preparation methods and material selection are as follows:

[0058] 1) Suspended solids rapid sedimentation agent A is prepared using chitosan-modified bentonite or montmorillonite composite materials: natural bentonite or montmorillonite is acidified and activated, and then composite modified with cationic polysaccharide chitosan. A stable complex is formed through electrostatic adsorption and intermolecular hydrogen bonding. Chitosan provides cationic sites in the composite system, which can neutralize the charge on the surface of negatively charged suspended particles and achieve polymer bridging, thereby realizing the rapid aggregation and sedimentation of suspended particles. This agent is suitable for non-biological turbid water bodies mainly composed of silt, colloids, and organic debris.

[0059] 2) Compound agent B is formed by combining polysaccharide organic components and metal salt inorganic components, preferably prepared by combining chitosan with iron or aluminum salts: by introducing metal ions or their hydroxyl complexes into the polysaccharide molecular chain, the compound has both cationic adsorption sites and inorganic bridging capabilities, thereby achieving dual removal of suspended particles and algae; the compound agent is suitable for mixed water bodies where both suspended matter and algae cause a decrease in transparency, and can achieve rapid clarification effect at a low dosage.

[0060] 3) Algae removal agent C uses iron or aluminum salt modified bentonite as the main preparation material: Bentonite is modified by ion exchange with metal salt solutions such as ferric chloride, ferric sulfate, or aluminum sulfate, introducing metal cation sites into the clay layers to form a composite structure with strong adsorption activity. The modified bentonite can generate electrostatic adsorption and chemical complexation reactions on the negatively charged groups on the surface of algal cells, achieving rapid sedimentation and removal of algae. This agent is suitable for eutrophic water bodies with high algal biomass and significantly reduced transparency.

[0061] This embodiment provides a water transparency enhancement device based on an intelligent linkage dosing system, which uses natural or modified biodegradable materials to ensure that the agent has good ecological safety and environmental friendliness.

[0062] According to an embodiment of the present invention, a method for improving water transparency based on an intelligent linkage dosing system is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0063] This embodiment provides a method for improving water transparency based on an intelligent linkage dosing system, which can be used in the data acquisition and discrimination module 104 of the aforementioned water transparency improvement device based on the intelligent linkage dosing system. Figure 2 This is a flowchart of a water transparency improvement method based on an intelligent linkage dosing system according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0064] Step S201: Obtain the water transparency, suspended solids concentration, and chlorophyll a concentration of the target water body within a preset monitoring time period; wherein, the water transparency is obtained by a water transparency sensor; the suspended solids concentration is obtained by a suspended solids concentration sensor; and the chlorophyll a concentration is obtained by a chlorophyll a sensor.

[0065] Specifically, the water transparency sensor, suspended solids concentration sensor, and chlorophyll a sensor continuously monitor relevant indicators of the target water body. Every 6 hours, the average values ​​of water transparency (SD), suspended solids concentration (SS), and chlorophyll a (a chemical substance) concentration (Chla) for the past three days are calculated, and this average value is used as the initial discrimination value of the automatic dosing discrimination program.

[0066] Step S202: Compare the water transparency, suspended solids concentration, and chlorophyll a concentration with preset thresholds.

[0067] Specifically, the preset thresholds include a transparency threshold, a first concentration threshold (i.e., a suspended matter concentration threshold), and a second concentration threshold (i.e., a chlorophyll a concentration threshold).

[0068] Step S203: Based on the comparison results, control the agent storage and dosing module and the agent spraying module to add agents to the target water body.

[0069] Specifically, when the data acquisition and discrimination module determines that a certain type of drug needs to be added, it sends a start command to the drug addition control module. The drug addition control module drives the valves and dosage control equipment of the corresponding drug storage chamber, and drives the solenoid valves and metering pumps of the corresponding drug pipeline of the drug spraying device to realize drug spraying.

[0070] This embodiment provides a method for improving water transparency based on an intelligent linkage dosing system. By constructing a closed-loop linkage system that integrates real-time transparency monitoring, intelligent cause identification, and dosing control, it achieves intelligent and automated improvement of water transparency. Based on the discrimination logic of fitted thresholds, it can accurately distinguish whether suspended matter or algae are the dominant factors, and select and add appropriate functional agents as needed. At the same time, it uses natural or modified biodegradable materials to ensure that the agents have good ecological safety and environmental friendliness. The overall solution is applicable to various scenarios such as lakes, reservoirs, and landscape water bodies, and has broad promotion and application value.

[0071] This embodiment provides a method for improving water transparency based on an intelligent linkage dosing system, which can be used in the data acquisition and discrimination module 104 of the aforementioned water transparency improvement device based on an intelligent linkage dosing system. Figure 3 This is a flowchart of a water transparency improvement method based on an intelligent linkage dosing system according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps:

[0072] Step S301: Obtain the water transparency, suspended solids concentration, and chlorophyll a concentration of the target water body within a preset monitoring time period; wherein, water transparency is obtained by a water transparency sensor; suspended solids concentration is obtained by a suspended solids concentration sensor; and chlorophyll a concentration is obtained by a chlorophyll a sensor. For details, please refer to [link to relevant documentation]. Figure 2 Step S201 of the illustrated embodiment will not be described again here.

[0073] Step S302 involves comparing water transparency, suspended solids concentration, and chlorophyll a concentration with preset thresholds. For details, please refer to [link to relevant documentation]. Figure 2 Step S202 of the illustrated embodiment will not be described again here.

[0074] Step S303: Based on the comparison results, control the agent storage and dosing module and the agent spraying module to add agents to the target water body.

[0075] Specifically, step S303 includes:

[0076] Step S3031: If the water transparency is less than the transparency threshold, then the suspended solids concentration is compared with the first concentration threshold, and the chlorophyll a concentration is compared with the second concentration threshold.

[0077] Specifically, the water transparency sensor continuously monitors the target water body. When the water transparency (SD) is detected to be lower than the transparency threshold (…), the sensor detects the water body's transparency (SD) and detects the water body's transparency (SD) to be lower than the transparency threshold (…). When the unit is cm, to avoid the control system being falsely triggered by temporary turbidity fluctuations caused by short-term wind, waves, rainfall, or construction disturbances, the SD average value is set to be less than [value missing] for three consecutive days. The time was right to initiate the drug dosing procedure.

[0078] Furthermore, if And satisfy or If the above triggering conditions are not met simultaneously, the dosing procedure will be initiated; if not, the dosing action will not be performed, and the monitoring data for this period will be stored in the cache for three-day sliding statistics. At the same time, the device will maintain the daily monitoring mode and continue to make judgments in the next 6-hour monitoring cycle.

[0079] Furthermore, based on the transparency threshold, the first concentration threshold and the second concentration threshold are determined by utilizing the mapping relationship between transparency and suspended matter concentration and chlorophyll a concentration, respectively.

[0080] Furthermore, by fitting and analyzing measured data from the target water body or representative water bodies, a nonlinear regression model was used to establish the mapping relationship between transparency and suspended solids concentration and chlorophyll a concentration, the expression of which is:

[0081]

[0082]

[0083] in, , , , These are the fitting parameters, determined through regression analysis using monitoring data from the target water body.

[0084] Furthermore, the set transparency thresholds are respectively Substituting into formulas (1) and (2) above, we obtain the first concentration threshold. Second concentration threshold This is used to determine the main reasons for the decrease in water transparency.

[0085] In step S3032, if the suspended solids concentration is greater than or equal to the first concentration threshold, or the chlorophyll a concentration is greater than or equal to the second concentration threshold, the agent dosing control module is controlled to deliver the agent to the agent spraying module, and the agent spraying module is driven to spray the agent onto the target water body.

[0086] In some optional implementations, step S3032 above includes:

[0087] Step a1: If the suspended solids concentration is greater than or equal to the first concentration threshold and the chlorophyll a concentration is less than the second concentration threshold, then a first dosing control command is sent to the agent dosing control module; wherein, the first dosing control command is used to control the agent storage and dosing module to deliver the suspended solids rapid settling agent to the agent spraying module, and drive the agent spraying module to spray the suspended solids rapid settling agent onto the target water body.

[0088] Specifically, when , When suspended particles are determined to be the main turbidity-causing factor, it is necessary to add a rapid settling agent for suspended solids. Then, a first dosing control command is sent to the agent dosing control module. The agent dosing control module delivers the rapid settling agent for suspended solids to the agent spraying module according to the first dosing control command. The agent spraying module sprays the rapid settling agent for suspended solids onto the target water body.

[0089] Step a2: If the suspended solids concentration is less than the first concentration threshold and the chlorophyll a concentration is greater than or equal to the second concentration threshold, a second dosing control command is sent to the agent dosing control module; wherein, the second dosing control command is used to control the agent storage and dosing module to deliver algae remover to the agent spraying module and drive the agent spraying module to spray algae remover onto the target water body.

[0090] Specifically, when , When algae overgrowth is determined to be the main turbidity factor, algae removal agent needs to be added. Then, a second addition control command is sent to the agent addition control module. The agent addition control module delivers the algae removal agent to the agent spraying module according to the second addition control command. The agent spraying module sprays the algae removal agent onto the target water body.

[0091] Step a3: If the suspended solids concentration is greater than or equal to the first concentration threshold and the chlorophyll a concentration is greater than or equal to the second concentration threshold, a third dosing control command is sent to the agent dosing control module; wherein, the third dosing control command is used to control the agent storage and dosing module to deliver the compound agent to the agent spraying module and drive the agent spraying module to spray the compound agent onto the target water body.

[0092] Specifically, when , When it is determined that suspended solids and algae are causing turbidity together, a compound agent needs to be added. Then, a third addition control command is sent to the agent addition control module. The agent addition control module delivers the compound agent to the agent spraying module according to the third addition control command. The agent spraying module sprays the compound agent onto the target water body.

[0093] This embodiment provides a method for improving water transparency based on an intelligent linkage dosing system. It establishes a logic to determine the causes of decreased transparency, distinguishing the contributions of suspended solids and algae. Based on monitoring data, it intelligently differentiates whether the decrease in transparency is caused by suspended particles, algae, or both. Then, it adds appropriate functional flocculants or agents as needed to precisely improve water transparency, achieving intelligent, precise, and ecological control of water transparency improvement. Furthermore, it utilizes the mapping relationship between transparency and suspended solids concentration and chlorophyll a concentration to determine a first concentration threshold and a second concentration threshold. Using these thresholds, it can accurately distinguish whether suspended solids or algae are the dominant factors, allowing for the selection and addition of appropriate functional agents as needed.

[0094] This embodiment provides a method for improving water transparency based on an intelligent linkage dosing system, which can be used in the data acquisition and discrimination module 104 of the aforementioned water transparency improvement device based on the intelligent linkage dosing system. Figure 4 This is a flowchart of a water transparency improvement method based on an intelligent linkage dosing system according to an embodiment of the present invention, such as... Figure 4 As shown, the process includes the following steps:

[0095] Step S401: Obtain the water transparency, suspended solids concentration, and chlorophyll a concentration of the target water body within a preset monitoring time period; wherein, water transparency is obtained by a water transparency sensor; suspended solids concentration is obtained by a suspended solids concentration sensor; and chlorophyll a concentration is obtained by a chlorophyll a sensor. For details, please refer to [link to relevant documentation]. Figure 3 Step S301 of the illustrated embodiment will not be described again here.

[0096] Step S402: Compare water transparency, suspended solids concentration, and chlorophyll a concentration with preset thresholds, respectively. For details, please refer to [link to relevant documentation]. Figure 3 Step S302 of the illustrated embodiment will not be described again here.

[0097] Step S403: Based on the comparison results, control the agent storage and dosing module and the agent spraying module to add agents to the target water body.

[0098] Step S404: Perform delayed monitoring on the target water body after the addition of the agent, obtain multiple water body transparency detection values ​​within the delayed monitoring period, and adjust the agent dosage based on the multiple water body transparency detection values.

[0099] Specifically, after the reagent is added, the system enters a delayed monitoring mode to avoid misjudgment caused by insufficient reagent reaction. The delayed monitoring logic is as follows: water transparency (SD) is monitored every 6 hours; if two consecutive measurements are negative... Perform compensation injection and re-enter the delay monitoring and feedback adjustment procedure; when three consecutive monitoring results... If the dosing procedure is interrupted, the system will switch to routine monitoring mode.

[0100] This embodiment provides a method for improving water transparency based on an intelligent linkage dosing system. By performing delayed monitoring of the target water body after the addition of chemicals, and adjusting the amount of chemicals added based on the transparency detection values ​​of multiple water bodies within the delayed monitoring period, the delayed monitoring of the target water body and the feedback adjustment of the amount of chemicals added are realized, forming a closed-loop control of "monitoring-discrimination-addition-feedback", which ensures the closed-loop operation of the water transparency improvement device based on the intelligent linkage dosing system.

[0101] The following specific embodiment illustrates the detailed steps of a method for improving water transparency based on an intelligent linkage dosing system.

[0102] Example 1:

[0103] A water transparency enhancement device that uses multiple sensors to monitor in real time, intelligently determine the causes of decreased water transparency, and add functional agents as needed includes a water transparency sensor, a suspended solids concentration sensor, a chlorophyll a sensor, a data acquisition and discrimination module, an agent addition control module, an agent storage and addition module, and an agent spraying module.

[0104] like Figure 5 As shown, the above-mentioned device is used for automatic drug dosing detection. The automatic drug dosing detection steps include:

[0105] The water transparency sensor continuously monitors the target water body. When the water transparency is detected to be lower than a set threshold (i.e., transparency threshold), to avoid false triggering of the control system due to temporary turbidity fluctuations caused by short-term wind, waves, rainfall, or construction disturbances, the system is set to have a three-day average SD value less than [a certain threshold]. The appropriate procedure for administering the pesticide is initiated, and the specific steps are as follows:

[0106] S1, Daily Monitoring Mode:

[0107] Water transparency, suspended solids concentration, and chlorophyll a sensor continuously monitor relevant indicators. The average values ​​of water transparency (SD), suspended solids concentration (SS), and chlorophyll a concentration (Chla) for the past three days are calculated every 6 hours, and the following judgments are made:

[0108] like And satisfy or When the time is right, the dosing procedure will be initiated.

[0109] If the triggering conditions are not met simultaneously, the system will not perform the drug administration action, but will only store the monitoring data for this period in the cache for three-day sliding statistics. At the same time, the device will maintain the daily monitoring mode and continue to make judgments until the next 6-hour monitoring period.

[0110] S2. Dosing procedure:

[0111] Based on the discrimination threshold (i.e., the first concentration threshold) Second concentration threshold Perform intelligent discrimination:

[0112] when , When suspended particles are determined to be the main turbidity-causing factor, it is necessary to add a rapid sedimentation agent for suspended solids.

[0113] when , When algal overgrowth is determined to be the main turbidity factor, it is necessary to add an algae removal agent;

[0114] when , If it is determined that suspended matter and algae are both causing turbidity, then a compound agent needs to be added.

[0115] When the data acquisition and discrimination module determines that a certain type of drug needs to be added, it sends a start command to the drug addition control module. The drug addition control module then drives the valves and dosage control devices of the corresponding drug storage chamber and the drug spraying module to achieve drug spraying.

[0116] S3, Delay Monitoring and Feedback Adjustment Procedure:

[0117] After the pesticide is added, a delayed monitoring mode is entered to avoid false alarms caused by incomplete pesticide reaction. The monitoring logic is as follows:

[0118] Water transparency (SD) is monitored every 6 hours. If two consecutive measurements are taken... The compensation injection is then performed, and the delay monitoring and feedback adjustment procedure is re-entered.

[0119] When three consecutive monitoring results If the dosing procedure is interrupted, the system will switch to routine monitoring mode.

[0120] In Example 1 above, transparency, suspended solids concentration, and chlorophyll a concentration are monitored in real time by multiple sensors. Based on a logic model for determining the cause of transparency decline, the device intelligently distinguishes whether the decline is caused by suspended particles, algae, or both, and adds rapid sedimentation agents, algae removal agents, or compound agents as needed to achieve automated improvement of transparency. The device has delayed monitoring and feedback adjustment functions, forming a closed-loop control of "monitoring-determination-addition-feedback". The agents used are chitosan-modified bentonite, iron / aluminum salt-modified bentonite, and their compound, which have good ecological safety. The device achieves intelligent, precise, and ecological control of water transparency improvement, and is suitable for the long-term operation and management of lakes, reservoirs, and landscape water bodies.
