Description

Technical Field

[0001] This invention relates to the field of water environment management technology, specifically to a rapid emergency intelligent treatment method and system for algal blooms in lakes. Background Technology

[0002] Enclosure technology, as a physical isolation method, is widely used in the treatment of cyanobacterial blooms, and it plays a key role in controlling the spread of cyanobacteria and ensuring the safety of aquatic ecosystems.

[0003] However, traditional fixed enclosures have gradually revealed their limitations in application. Once their location and shape are determined, they are difficult to adjust flexibly, making them ill-suited to complex and changing hydrological conditions and treatment needs. In some cases, fixed enclosures may fail to completely cover areas where cyanobacteria accumulate, resulting in poor treatment effects; and in the event of an emergency, their fixed nature limits the ability to respond and adjust quickly. Furthermore, fixed enclosures may obstruct the natural flow of water, affecting the water body's self-purification mechanism and ecological balance, further exacerbating water pollution problems. Simultaneously, the long-term exposure of fixed enclosures to the natural environment makes them susceptible to damage from wind, rain, and sun aging, requiring regular maintenance and replacement, which undoubtedly increases treatment costs and maintenance difficulty. In addition, specific cyanobacteria control measures (such as the administration of biological agents and water quality regulation) need to be implemented inside the enclosure, requiring additional investment of human, material, and financial resources. Therefore, designing a semi-open enclosure with freely exchangeable underlying water and its accompanying intelligent cyanobacteria control measures is particularly important.

[0004] To address the shortcomings of fixed enclosures for isolating target areas and the inaccurate and uneven application of algaecides after cyanobacterial blooms, a rapid emergency intelligent treatment method and system for lake algal blooms based on semi-open enclosures needs to be developed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the aforementioned background technology and provide a rapid, intelligent emergency response method for lake algal blooms. The core of this invention lies in the construction of a semi-open intelligent enclosure with freely flowing water below and the precise, intelligent implementation of treatment strategies within the enclosure. It adopts a modular standard unit design, which can be flexibly combined according to the actual conditions of the water area. This not only simplifies the installation process but also effectively isolates polluted areas through rapid deployment and adjustment, significantly shortening the construction cycle and creating favorable conditions for subsequent treatment.

[0006] The technical solution of this invention is: a rapid emergency intelligent treatment method for algal blooms in lakes, comprising the following steps:

[0007] Multiple long, standard baffles are connected end to end to form a baffle that surrounds the algal bloom area. The top of the standard baffles floats on the water surface and the bottom has a vertical gap with the bottom of the water.

[0008] The monitoring devices within the enclosure acquire geographical location information and water chlorophyll concentration information and transmit them to the cloud processing platform. The cloud processing platform plans the driving route based on the geographical location information and determines the dosage of flocculant and biological inhibitor based on the chlorophyll concentration.

[0009] The unmanned vessels loaded flocculants and biological inhibitors in sequence according to their respective dosages, and after each loading, they entered the enclosure along the driving route to distribute them.

[0010] This invention employs standard partition panels assembled into a semi-open enclosure. This enclosure can isolate the surface cyanobacteria diffusion area to a certain extent while maintaining the natural flow of water below, reducing the impact on the overall lake ecosystem. The enclosure is constructed using modular integration, allowing for flexible adjustment of its size and location according to actual conditions. Combined with advanced monitoring technology and an intelligent control system, this invention achieves real-time monitoring of cyanobacteria distribution and density. Based on the monitoring results, the system can automatically calculate and adjust the dosage of algae control agents, achieving precise application. This precise application method not only improves algae removal efficiency but also significantly reduces the amount of agents used and the potential environmental impact.

[0011] Preferably, each standard partition includes a long strip of partition fabric, an inflatable airbag at the top of the partition fabric, and a stainless steel anchor chain at the bottom of the partition fabric. Connecting ropes are provided at the top of both ends of the partition fabric, and magnetic attraction parts with opposite magnetic properties are provided at both ends of the partition fabric. These magnetic attraction parts are strip-shaped and arranged along the width direction of the partition fabric.

[0022] Furthermore, the dosage can be calculated using formula (2):

[0023] W = M × B × h × C (2)

[0024] Where W represents the dosage of the biological inhibitor, in grams;

[0025] M represents the flocculant dosage, in grams.

[0026] B represents the surface area of ​​cyanobacteria precipitation per gram of flocculant, ranging from 200 to 1000 m². 2 / g;

[0027] h represents the thickness of the flocculent at the bottom of the water, ranging from 0.1 to 0.2 m.

[0028] C represents the tolerance concentration of cyanobacteria to bioinhibitors, ranging from 0.01 to 0.05 mg / L.

[0029] Preferably, the enclosure is provided with one or more monitoring devices at intervals on the inner wall. The monitoring device includes a sensor module that can measure chlorophyll concentration, a positioning module that can acquire geographical location information, and a data processing and communication module that can process and transmit the signals from the sensor module and the positioning module. The data processing and communication module is connected to the cloud processing platform.

[0030] When multiple monitoring devices are used, the cloud processing platform determines the dosage of flocculant and biological inhibitor based on the maximum chlorophyll concentration measured by all monitoring devices.

[0031] Preferably, the unmanned vessel includes a hull and a dispensing device installed on the hull, wherein the unmanned vessel loads flocculant and biological inhibitor sequentially onto the dispensing device according to their respective dosage amounts;

[0032] The process of dispersing the flocculant within the enclosure after each loading operation specifically involves: after each loading, the cloud processing platform controls the vessel to navigate along the designated route into the enclosure; once inside, the platform controls the dispersing device to distribute the flocculant; and after dispersal is complete, the platform controls the vessel to return to port. Furthermore, the bio-inhibitor is administered one day after the flocculant is applied.

[0033] This invention also provides a rapid emergency intelligent treatment system for lake algal blooms, comprising:

[0034] The enclosure consists of multiple long, standard enclosure panels connected end to end to form an enclosure that surrounds the algal bloom area. The standard enclosure panels have a vertical distance from the bottom of the water body. The inner wall of the enclosure is equipped with a monitoring device, which includes a sensor module that can measure chlorophyll concentration, a positioning module that can acquire geographical location information, and a data processing and communication module that can process and transmit the signals from the sensor module and the positioning module.

[0035] An unmanned surface vessel, comprising a hull and a dispensing device mounted on the hull;

[0036] The cloud processing platform is connected to the data processing and communication module to receive and process geographical location information and chlorophyll concentration information; the cloud processing platform is also connected to the unmanned vessel to control the vessel's movement and the opening and closing of the dispensing device.

[0037] Preferably, each standard partition includes a long strip of partition fabric, an inflatable airbag set at the top of the partition fabric, and a stainless steel anchor chain set at the bottom of the partition fabric. The top of both ends of the partition fabric is provided with connecting ropes, and the top and bottom ends of the partition fabric are respectively provided with magnetic attraction parts with opposite magnetic properties.

[0040] The beneficial effects of this invention include:

[0041] (1) The semi-open enclosure, assembled from standard enclosure panels, is a water management structure that falls between completely closed and completely open. It allows free exchange of water below the enclosure while effectively isolating and controlling algae floating on the water surface. This design is efficient and convenient to install, while avoiding the ecological imbalance caused by the complete closure of water bodies by current fixed enclosures, and also overcoming the difficulty of centralized implementation of management measures in open environments.

[0042] (2) The top of the standard enclosure is equipped with an inflatable airbag to keep the top of the enclosure always at the water surface. The stainless steel anchor chain can be used as a counterweight or as a connection part. The two ends of the standard enclosure are equipped with opposite magnetic suction parts. When two adjacent standard enclosures are connected, the upper end is connected by a connecting rope, the middle part is connected by a magnetic suction part, and the lower end is connected by a stainless steel anchor chain buckle. The two are firmly connected and vertically kept in place to prevent blue algae from escaping from the gaps.

[0043] (3) The emergency intelligent treatment system integrates intelligent monitoring, precise positioning, and automated control technologies, enabling accurate identification of algae growth areas and precise application of pesticides. Monitoring devices installed on the enclosure can monitor chlorophyll concentration in the water in real time. The cloud-based treatment platform can automatically adjust the pesticide application strategy of the unmanned vessel based on this data, achieving precise positioning and quantitative application of the pesticides. This intelligent and automated application method not only improves the utilization rate of the pesticides but also reduces the potential impact on the aquatic environment, ensuring the high efficiency and environmental friendliness of the treatment measures.

[0044] (4) After the unmanned vessel reaches the designated location, it activates the agent application device and applies the agent according to the predetermined dosage. The combined application of new containment and intelligent management measures makes the entire treatment process more efficient and convenient, reduces labor costs, and provides a more scientific, efficient, and economical solution for the management of cyanobacterial blooms.

Detailed Implementation

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, all raw materials and equipment used in this application can be purchased on the market or prepared by existing methods. The following specific embodiments will further describe the present invention in detail.

[0052] To address the shortcomings of existing technologies, such as fixed enclosures that isolate the target area and the inaccurate and uneven application of algaecides by manual application, this invention uses standardized enclosure panels with uniform structures. Based on monitoring results from devices within the enclosure, a cloud-based processing platform automatically calculates and adjusts the dosage and location of the algaecide application, achieving precise application. This precise application method not only improves algae control efficiency but also significantly reduces the amount of algae used and its potential environmental impact.

[0053] This invention provides a rapid emergency intelligent treatment system for lake algal blooms, including containment, unmanned vessels, and a cloud processing platform.

[0054] The enclosure is formed by connecting multiple long, standard enclosure panels 10 end to end, creating a complete ring around the area where the algal bloom occurred. The specific shape is not limited and is determined based on the actual shape of the algal bloom area; it can be square, circular, polygonal, or even a ring along the entire lakeshore. The structure of each standard enclosure panel 10 is as follows: Figure 1 As shown, it includes a long strip-shaped partition cloth 2, an inflatable airbag 1 set at the top of the partition cloth 2, and a stainless steel anchor chain 3 set at the bottom of the partition cloth 2. The top of both ends of the partition cloth 2 are provided with connecting ropes 4, and the top and bottom ends of the partition cloth 2 are respectively provided with magnetic suction parts 5 with opposite magnetic properties. The magnetic suction parts 5 are strips set along the width direction of the partition cloth 2. Figure 1 The left-right direction is the length direction of the standard partition 10, and the up-down direction is the width direction of the standard partition 10. Each standard partition 10 is 1.5-2 meters long and 0.4-0.8 meters wide. The partition fabric 2 is preferably PVC fabric, and the inflatable airbag 1 is made of rubber.

[0055] Each standard partition 10 has one end as the beginning and the other end as the end along its length. The magnetic attraction parts 5 at the beginning and end are opposite in magnetism. The magnetic attraction parts 5 at the beginning of all standard partitions 10 are magnetically positive / negative, while the magnetic attraction parts at the end are magnetically negative / positive. Therefore, when two standard partitions 10 are assembled and connected, the magnetic attraction parts 5 at the beginning of one standard partition 10 and the magnetic attraction parts 5 at the end of the other standard partition 10 are attracted by opposite magnetism and thus fit together.

[0056] In some preferred embodiments, the connecting ropes 4 at both ends of the partition fabric 2 are formed by a single long rope that runs the length of the partition fabric 2 with both ends exposed. The inflatable airbag 1 and the stainless steel anchor chain 2 are both arranged along the length of the partition fabric 2, and the magnetic part 5 extends from the upper end to the lower end of the partition fabric 2 along its width. Standard partition panels 10 are assembled into a partition as shown. Figure 2 As shown, the connecting ropes 4 at the beginning and end of the two adjacent standard partitions 10 are connected to each other, the magnetic parts 5 are attached to each other, and the stainless steel anchor chains 3 are connected by buckles.

[0057] Monitoring devices 20 are installed on the inner walls of the enclosure. There may be one or more monitoring devices 20, but in some preferred embodiments, there are multiple devices. These are installed on the inner walls of standard enclosure panels 10 at selected intervals, such as square enclosures, with one monitoring device 20 on each side. The installation method of the monitoring devices 20 can be as follows: Figure 1 As shown, an installation part 6 is provided on the inner wall of the partition cloth 2, and the monitoring device 20 is detachably connected to the installation part 6, for example, magnetically attached to the installation part 6.

[0058] like Figure 3 As shown, the monitoring device 20 includes a sensor module 21 that can measure chlorophyll concentration, a positioning module 22 that can acquire geographical location information, and a data processing and communication module 23 that can process and transmit the signals from the sensor module 21 and the positioning module 22.

[0059] The unmanned surface vessel in this invention includes a hull and a dispensing device installed on the hull.

[0060] In this invention, the cloud processing platform is signal-connected to the data processing and communication module 23 to receive geographical location information and chlorophyll concentration information; the cloud processing platform is signal-connected to the unmanned vessel to control the vessel's movement and the opening and closing of the dispensing device.

[0061] like Figure 4 As shown, the method for rapid emergency intelligent handling of lake algal blooms using the above system includes the following steps:

[0062] Step 1: When an algal bloom occurs in a local area of ​​the lake, immediately conduct an on-site survey, transport multiple long strip standard enclosure panels 10 to the site, and assemble them into enclosures.

[0063] The specific assembly process is as follows: connect the connecting ropes 4 at the beginning and end of the two standard enclosures 10, attach the magnetic parts 5 to each other, and connect the stainless steel anchor chains 3 with buckles. The magnetic parts 5 can ensure that the two adjacent standard enclosures 10 are tightly attached vertically to prevent blue-green algae from escaping from the gaps. Some standard enclosures 10 are also equipped with corresponding monitoring devices 20 until all standard enclosures 10 are connected end to end to form a complete circle of enclosures.

[0064] Next, inflate the airbags 1 of all standard enclosure panels 10. This can be done individually or by connecting all the airbags 1 together and inflating them all at once. This allows the top of the enclosure to rapidly expand above the water surface and reach the predetermined shape and size, quickly forming an isolation zone that surrounds the area of ​​the algal bloom. The vertical distance between the standard enclosure panels 10 and the bottom of the water body is half the water depth, facilitating free flow of the water below.

[0065] Step 2: Use the monitoring device inside the enclosure to obtain geographical location information and water chlorophyll concentration information and transmit them to the cloud processing platform. The cloud processing platform plans the unmanned vessel's route based on the geographical location information provided by the monitoring device 20, and determines the dosage of flocculant and biological inhibitor based on the chlorophyll concentration.

[0066] The variation range of chlorophyll concentration in the water body is detected by monitoring devices 20 located at different positions within the enclosure. The data is transmitted to a cloud processing platform, which calculates the dosage of each agent (flocculator and bio-inhibitor) based on the chlorophyll concentration. When multiple monitoring devices are available, the cloud processing platform uses the maximum chlorophyll concentration as C. (chl) Calculate the dosage.

[0067] Flocculants can adsorb algal cells and other organic and inorganic particles suspended in water, causing these particles to aggregate into larger clumps through charge neutralization or bridging. These clumps quickly sink to the bottom of the water due to gravity, thus removing surface algae. The algae that sink to the bottom are killed by biological inhibitors that specifically infect algal cells, inhibiting their growth and reproduction. In this invention, the effective component of the flocculant is one or more of polyaluminum chloride, polyacrylamide, and chitosan, and the content ω of the effective component in the flocculant is generally 10-30% (mass fraction); the biological algaecide is one or more of algae-inhibiting bacteria and cellulase.

[0068] The dosage of flocculant can be calculated using formula (1):

[0069] C (chl) ×H×A×Z×10 3 =M×ω(1)

[0070] Among them, C (chl) The chlorophyll concentration of the water to be treated is expressed in μg / L.

[0071] H represents the vertical distribution distance of cyanobacteria in the surface water, in meters (m).

[0072] A represents the area of ​​the enclosed region, in meters (m²). 2 ;

[0073] Z represents the cyanobacteria flocculation and sedimentation rate, which is generally taken as 0.92 to 0.98.

[0074] M represents the dosage of flocculant, in grams.

[0075] ω represents the mass percentage of the effective component in the flocculant, which is generally taken as 10-30%.

[0076] The biological inhibitor is added one day after the flocculant is added, and the dosage can be calculated using formula (2):

[0077] W = M × B × h × C (2)

[0078] Where W represents the dosage of the biological inhibitor, in grams;

[0079] M represents the flocculant dosage, in grams.

[0080] B represents the surface area of ​​cyanobacteria precipitation per gram of flocculant, ranging from 200 to 1000 m². 2 / g;

[0081] h represents the thickness of the flocculent at the bottom of the water, ranging from 0.1 to 0.2 m.

[0082] C represents the tolerance concentration of cyanobacteria to bioinhibitors, ranging from 0.01 to 0.05 mg / L.

[0083] Step 3: The flocculant and biological inhibitor (according to their respective determined dosages) are loaded separately in two stages onto the unmanned surface vessel's (USV) dispensing device. After each loading, the cloud processing platform sends a travel route to the USV. The vessel enters the enclosure according to the route and is controlled to travel in a direction that gradually decreases the chlorophyll concentration within the enclosure. After the vessel enters the enclosure, the cloud processing platform activates the dispensing device to dispense the flocculant according to the determined dosage. After dispensing is complete, the platform controls the vessel to return along the same route. The biological inhibitor is added one day after the flocculant is added.

[0084] Example 1

[0085] Taking a lake in Wuhan as an example, after a prolonged period of high temperatures in summer, a blue-green algae bloom occurred in the lake. A rapid emergency intelligent treatment method for lake algal blooms was implemented, including the following steps:

[0086] Step 1: When an algal bloom occurs in a local area of ​​the lake, immediately conduct an on-site survey, transport multiple long strip standard enclosure panels 10 to the site, and assemble them into enclosures.

[0087] Technicians immediately conducted an on-site investigation and determined that the water depth in the area of ​​the cyanobacteria outbreak was 1.2 meters and the area A = 1000 m². 2 The dimensions of a single standard enclosure 10 are determined to be 1.5 meters long and 0.6 meters wide. Adjacent standard enclosures 10 are connected end-to-end by connecting ropes 4, magnetic attachment parts 5, and stainless steel anchor chains 3. Multiple monitoring devices 20 are magnetically fixed to the mounting parts 6 of the standard enclosure 10. Then, the inflation device is connected to the inflation airbag 1 and inflated to a pressure of 3 atmospheres. After inflation, the enclosure rapidly expands on the water surface and reaches the predetermined shape and size, forming an isolation zone. The vertical distance between the standard enclosure 10 and the bottom of the water body is 0.6 meters (half the water depth).

[0088] Step 2: Use the monitoring device 20 inside the enclosure to obtain geographical location information and water chlorophyll concentration information and transmit them to the cloud processing platform. The cloud processing platform plans the route according to the geographical location information provided by the monitoring device 20 and determines the dosage of flocculant and biological inhibitor according to the chlorophyll concentration.

[0089] Monitoring devices 20 at different locations detected chlorophyll concentrations in the water ranging from 60 to 120 μg / L. After transmitting the data to a cloud processing platform, analysis showed that the chlorophyll concentration in the downwind water was higher than that in the upwind water due to wind direction. The maximum chlorophyll concentration, C, was taken. (chl) =120μg / L, vertical distribution distance of cyanobacteria in water H=0.4m, cyanobacteria flocculation sedimentation rate Z=0.95, calculated, the mass percentage of effective component (polyaluminum chloride) in the flocculant ω=25%, and the surface area of ​​cyanobacteria sedimentation per gram of flocculant B=500m² 2 / g, the thickness of the floc at the bottom of the water is h=0.1m, and the tolerance concentration of the cyanobacteria to the biological inhibitor is C=0.01mg / L.

[0090] Calculations based on the cloud processing platform show that the amount of flocculant applied to the enclosure area is M = 182.4 kg, and the amount of biological inhibitor applied is W = 91.2 kg.

[0091] Step 3: Load the flocculant and bio-inhibitor sequentially onto the unmanned surface vessel's (USV) dispensing device according to their respective dosages (first loading: flocculant M = 182.4 kg; second loading: bio-inhibitor W = 91.2 kg). After each loading, the cloud processing platform sends the navigation route to the USV. The vessel enters the enclosure according to the planned route and is controlled to move in a direction that gradually decreases the chlorophyll concentration within the enclosure. After the vessel enters the enclosure, the cloud processing platform activates the dispensing device to dispense the agents according to the determined dosages (flocculinant M = 182.4 kg; bio-inhibitor W = 91.2 kg), and controls the vessel to return after dispensing is complete. The bio-inhibitor is added one day after the flocculant is added.

[0092] The treatment results are shown in Table 1 below.

[0093] Table 1 Comparison of data before and after treatment

[0094]

[0095] As can be seen from Table 1 above, after 7 days of application of all the agents, the chlorophyll concentration dropped to about 1 / 5 of that before treatment, and the transparency was about twice that before treatment, indicating a significant algae removal effect.
