Description

Technical Field

[0001] This invention relates to the field of algae management technology, specifically a method for effectively managing algae in water bodies. Background Technology

[0002] Algae are a type of eukaryote (some are also prokaryotes, such as cyanobacteria) in the protist kingdom. They are primarily aquatic, lack vascular bundles, and are capable of photosynthesis. They vary greatly in size, from tiny single-celled flagellates only 1 micrometer long to large brown algae reaching 60 meters in length. Some leading experts continue to classify algae as plants or plant-like organisms, but algae lack true roots, stems, and leaves, and also lack vascular bundles. This is similar to bryophytes.

[0003] When applying for this invention, the applicant, after searching, discovered a Chinese patent disclosing a "Comprehensive Treatment Method for Eutrophic Waters," application number "200510092905.7." This patent mainly uses mechanized methods to quickly remove floating debris, including algal blooms, from the water surface, significantly reducing nitrogen and phosphorus content by removing large amounts of algae particles from the water; b) a water flow promotion step: directly setting up water flow creation equipment in the water area to drive water flow and create a dynamic water environment to disrupt excessive algal growth; c) a biofilm cultivation step: directly setting up microbial carriers in the water area to cultivate a large number of indigenous microorganisms to form a biofilm, using the biofilm to intercept and prey on algae and comprehensively degrade pollutants. However, mechanized cleaning is relatively troublesome, and the use of water flow creation equipment to drive water flow cannot be used for specific water areas. If forced to use it, it would consume a lot of money and energy. Therefore, based on the applicant's invention, a method that can effectively treat algae in water areas and save labor and costs has been invented, solving the problem of high cost and energy consumption of some treatment methods. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of existing technologies, this invention provides an effective method for controlling algae in water bodies, which solves the problem that some control methods require a large amount of funds and energy.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a method for effectively controlling algae in water bodies, comprising the following steps:

[0008] Step 1: Weighing quicklime: Take out quicklime and weigh it, then put the weighed quicklime into the lime slaking machine;

[0009] Step 2: Making slaked lime: Add an appropriate amount of water to the lime slaked machine, stir the refined lime milk together, and test the concentration of the lime milk;

[0010] Step 3: Trial feeding of algae-eating fish: Place several algae-eating fish of similar health status in several water cages, attach a pH meter to the water cages, and immerse them in the water to be treated, keeping them at a distance from each other, and feed them the same amount of food at regular intervals every day.

[0011] Step 4: Quantitatively add quicklime milk, chitosan oligosaccharide and artemisia argyi water extract: Take a quantitative amount of quicklime milk, chitosan oligosaccharide and artemisia argyi water extract, and take a quantitative amount of silt from the water area to mix with quicklime milk, chitosan oligosaccharide and artemisia argyi water extract, and evenly add the mixed materials into the water area.

[0012] Step 5: Check the status: After feeding the algae-eating fish, check their health status. If their health status is good and the pH value displayed by the pH meter does not exceed the pH value that the algae-eating fish can accept, continue feeding. If the health status of the algae-eating fish or the pH value displayed by the pH meter is abnormal, stop feeding.

[0013] Step Six: Release Algae-Eating Fish in Appropriate Amounts: Release different types of algae-eating fish into different areas.

[0014] Preferably, step one: weighing quicklime: take out quicklime and weigh it. The weight of quicklime is 20-30 kg. Put the weighed quicklime into the lime slaking machine.

[0015] Preferably, in step two: preparing slaked lime: An appropriate amount of water is added to the lime slaker, the amount depending on the quantity of quicklime. The final concentration of the lime slurry is controlled at 80%-90%. The prepared lime slurry is stirred, and its concentration is monitored. The final lime slurry is then stirred and mixed. This method uses lime slurry to inhibit algae growth. Lime slurry is inexpensive, saving on algae control costs. The calcium ions in the lime slurry are beneficial to the growth and development of fish and shrimp, providing a favorable environment for subsequent algae-eating fish growth, thus accelerating algae removal. Adding lime slurry in small, multiple batches avoids affecting the pH of the water body, preventing pH levels from being unsuitable for certain algae-eating fish. Multiple types of algae-eating fish can cope with different types of algae, increasing the method's applicability. Regional release based on the species of algae-eating fish and algae aggregation points allows for rapid reproduction of all species in the initial period, preventing cannibalism and improving the overall algae removal speed.

[0016] Preferably, step three, the trial introduction of algae-eating fish, involves placing several algae-eating fish of similar health conditions into multiple cages. The types of algae-eating fish include plecos, algae-eating mice, black mollies, black-striped flying foxes, and kissing bass. Different species of algae-eating fish are separated within the cages. A pH meter is attached to each cage, and the cages are then immersed in the water to be treated, with the cages kept separate. The same amount of food is fed to each cage at regular intervals daily. This process ensures that the final pH value of the water is suitable for the survival of these algae-eating fish, providing them with a suitable living environment and thus accelerating the algae removal process.

[0017] Preferably, step four involves the quantitative addition of slaked lime milk, chitosan oligosaccharide, and Artemisia argyi water extract: Weigh 15-35 kg of slaked lime milk, 1-3 kg of chitosan oligosaccharide, and 1-10 kg of Artemisia argyi water extract, and mix 10-20 kg of silt from the water with the above-mentioned slaked lime milk, chitosan oligosaccharide, and Artemisia argyi water extract to form a mixture. One portion of this mixture is then added to each acre of water. Chitosan oligosaccharide and Artemisia argyi water extract significantly enhance the algae-removing effect of slaked lime milk. Experiments have shown that adding chitosan oligosaccharide and Artemisia argyi water extract significantly improves the algae removal effect compared to adding slaked lime milk alone. Simultaneously, adding the mixture in small, multiple batches avoids the pH value in the water affecting the health of algae-eating fish and prevents situations where the pH value is unsuitable for the growth of a particular algae-eating fish. Furthermore, the mixture of silt and water improves the bottom soil quality, increases soil fertility, and enhances the mineral elements in the water, effectively acting as a direct fertilizer.

[0018] The extraction method of the mugwort water extract is as follows: Mugwort is chopped into small pieces, and the small pieces are added to deionized water at a solid-liquid mass ratio of 1:30 to form an extraction mixture. The extraction mixture is kept at a constant temperature of 80±5℃ in a water bath for more than 10 hours. During the heat preservation process, the mixture is refluxed and cooled to room temperature. The solid and liquid are separated, and the liquid phase is concentrated under reduced pressure to 1 / 4 of the original volume to obtain the mugwort water extract.

[0019] Preferably, in step five: monitoring status: After daily quantitative feeding, check the health status of the algae-eating fish every 7-8 days. If their health is good and the pH value displayed by the pH meter does not exceed the pH value acceptable to the algae-eating fish, continue feeding. If the health of the algae-eating fish or the pH value displayed by the pH meter is abnormal, stop feeding. This maximizes the inhibition of algae growth while avoiding the impact of pH on the algae-eating fish, achieving the best algae-clearing effect.

[0020] Preferably, step six: releasing an appropriate amount of algae-eating fish: different types of algae-eating fish are released into different areas, and the algae-eating fish are released into areas where that type of algae grows abundantly, according to the type of algae they feed on. The stocking density is 1-7 g / m³. 3By releasing algae-eating fish into different areas based on their species and algae aggregation points, all species of algae-eating fish can reproduce rapidly in the initial period, while avoiding cannibalism among them in the early stages, thus improving the overall algae clearing speed.

[0021] Working principle: Weigh 20-30 kg of quicklime and add it to a lime slaker. Add an appropriate amount of water, the amount depending on the quantity of quicklime, to maintain a lime slurry concentration of 80%-90%. Stir the lime slurry and monitor its concentration. Mix the final lime slurry. Place several algae-eating fish of similar health in separate cages. The algae-eating fish species include plecos, algae-eating loaches, black mollies, black-striped flying foxes, and chub. Separate the different species within the cages. Attach a pH meter to each cage and then immerse it in the water to be treated. The cages and water cages are separated, and the same amount of food is fed to the fish at fixed times every day. The mixture of quicklime milk, chitosan oligosaccharide, and Artemisia argyi water extract is weighed and mixed with silt from the water area. This mixture is then added to the water. After daily feeding, the health of the algae-eating fish is checked every 7-8 days. If the fish are healthy and the pH level shown on the pH meter does not exceed the acceptable pH level for the algae-eating fish, feeding continues. If the fish's health or the pH level shown on the pH meter is abnormal, feeding is stopped. Different types of algae-eating fish are released into different areas, according to the type of algae they consume, into areas where that type of algae grows abundantly. The stocking density is 1-7 g / m². 3 .

[0022] (III) Beneficial Effects

[0023] This invention provides an effective method for controlling algae in water bodies. It has the following beneficial effects:

[0024] 1. Quicklime is used to inhibit algae growth, preventing it from affecting the survival of algae-eating fish. Quicklime is also inexpensive, reducing the cost of water treatment. Adding chitosan oligosaccharides and Artemisia argyi water extract significantly improves algae removal compared to adding slaked lime alone. Simultaneously, the mixture of sludge and lime improves the pond bottom soil, increases soil fertility, and enhances the mineral content of the water, acting as a direct fertilizer and providing favorable conditions for the survival of algae-eating fish.

[0025] 2. By adding lime slurry in small amounts multiple times, the pH value of the water can be adjusted to avoid affecting the health of algae-eating fish and prevent the pH value from being unsuitable for the growth of a particular algae-eating fish. At the same time, the method can be used to feed a variety of algae-eating fish to different types of algae, which increases the applicability of the method. Only the addition and monitoring of the lime slurry are required, which avoids energy consumption and an increase in the workload of the staff.

[0026] 3. Algae-eating fish species are released in designated areas based on algae aggregation points. Since fish naturally prefer to eat food within their suitable living environment, this targeted release further selects a suitable living environment for the algae-eating fish. With sufficient food, all species of algae-eating fish can reproduce rapidly in the initial period, while avoiding cannibalism among algae-eating fish in the early stages, thereby improving the overall algae clearing speed.

[0062] Results of algae removal rates in the above embodiments: After treating algae in the water area according to the methods described in the above embodiments for 6 days, the algae removal results were tested, and the algae removal rate was calculated. The water area without any treatment served as the control group. Algae removal rate = (number of algae cells in the control group - number of algae cells in the embodiment group) ÷ number of algae cells in the control group × 100%. The results are as follows: Figure 2 As shown. By Figure 2 It can be seen that chitosan oligosaccharide and Artemisia argyi water extract have a significant synergistic promoting effect on the algae removal effect of quicklime milk.
