Problems solved by technology

[0007] 2. After domestic animals and wild animals drink water containing algae toxins, symptoms such as diarrhea, fatigue, vomiting, lethargy, and even death will occur.
Cyanobacteria can release secondary metabolites of biological toxins. Water bodies containing a certain concentration of algal toxins can cause fish eggs to mutate, fleas to die, fish behavior and growth to be abnormal, and algal blooms often cause a large number of aquatic organisms to die; Algal toxins accumulated in vertebrates and invertebrates, including fish, shellfish and zooplankton, may endanger human health through the cumulative effect of the food chain
[0009] 4. The migration of toxin-containing cyanobacteria cells in the water body, such as co-precipitation with clay, or precipitation with their granular excrement after being preyed on by aquatic organisms, causes the accumulation of toxins and stays in the substrate, which may have continuous effects on the water environment. Impact
[0010] 5. When the algae bloom occurs, the water surface is covered by thick blue-green lake indigo, and even accumulates on the shore. When the algae die, they will emit a foul smell and seriously damage the landscape.
[0019] In summary, the ultrasonic method in the physical algae removal method is simple and easy to implement, but it consumes a lot of energy and will affect the plants, microorganisms and fish in the water body. The ultrasonic diffusion range is limited and is not suitable for large-scale algal bloom water bodies; It is easy to operate, but the filter screen will be clogged if the filtration time is long, and the filter screen needs to be cleaned regularly, and the algae bloom cannot be cured, so it is not suitable for large-scale algal bloom water bodies; the dehydration method is more economical, but it is also not suitable for large-scale algal bloom water bodies
[0020] Chemical algae removal methods such as using herbicides, algicides and metal salts to control algae are simple and fast, suitable for treating large-scale algae blooms, and have good algae removal effects, but chemical algae removal agents may cause secondary pollution to the environment and are easy to pass through The food chain endangers human health
[0021] The biological manipulation method in the biological algae removal method will not damage the water body environment, but it is believed that creating a food chain requires many implementation links, which is cumbersome and costly, and the results are slow; the microbial algae removal method can efficiently and specifically remove algae, and can die and degrade naturally after the algae are killed, and do not harm the environment. When the concentration of cyanophage is lower than a certain threshold, the inactivation rate of cyanophage will exceed its contact rate with the host, resulting in a decline in the number of viruses , and in large water bodies, it is more difficult to keep the titer of the virus above a certain threshold, which hinders the development of cyanophages in the control of water blooms
Therefore, the method of biological algae removal still needs further research.

[0048] Example 1: Killing Microcystis aeruginosa DS by using antibacterial and deodorant fiber fabric

[0049] 1. Take Microcystis aeruginosa DS1000mL (biomass: chlorophyll a content 5.97mg / L) in the logarithmic growth phase cultivated in the laboratory with BG11 medium, add antibacterial and deodorant fiber fabric cloth cut into 2.5cm×8cm size Bar 10 carry out algae killing.

[0050] 2. Extract chlorophyll a from algae liquid every day to measure the biomass of Microcystis aeruginosa DS, and observe the change of biomass of Microcystis aeruginosa DS after algae killing by antibacterial and deodorant fiber fabric.

[0051] 3. From the 3rd day after the antibacterial and deodorant fiber fabric was put in, the biomass of Microcystis aeruginosa DS decreased, and the algal cells died, cracked and suspended in water or sank to the bottom of the bottle. After that, the biomass of Microcystis aeruginosa DS decreased day by day, and all algal cells died on the 21st day. please see ...

Abstract

The invention discloses the application of antibiotic and odor resistant fiber fabric for killing water bloom algae, which uses modified acrylic composite fiber in combined sub copper ions and basic green groups to be safe and has no harm to aquatic animals and plants formed during chemical treatment for killing the water bloom algae. The method comprises the following processes: the antibiotic and odor resistant fiber fabric is placed in water with the water bloom algae (or the antibiotic and odor resistant fiber fabric is used directly, made into cloth or membrane, weaved into mesh, or weaved into float grass, etc.) and floats in the water with the water bloom algae, thus causing the antibiotic fiber to have the function for cells of water bloom algae and killing the cells of the water bloom algae, so as to result in the recovered clear and transparent water. The application of antibiotic and odor resistant fiber fabric for killing water bloom algae has the advantages of simple operation, convenient implementation in vireos water with the water bloom algae, easy claiming and clearing, high efficiency in killing algae, complete treatment for water bloom, fast function, and no environment pollution.

Description

technical field [0001] The invention relates to the technical field of biological algae removal, and more specifically relates to the use of an antibacterial fiber fabric in killing algae, and is especially suitable for the control of blue-green algae blooms. Background technique [0002] At present, with the acceleration of the industrial process and the rapid development of the economy, the discharge of a large amount of industrial and agricultural wastewater, the discharge of domestic sewage and the self-pollution of the artificial breeding industry have led to the increasingly serious phenomenon of eutrophication in water bodies, which has become a problem faced by countries all over the world. Major environmental issues have also become the most pressing environmental issues in our country. According to a recent survey, 53%, 28%, 48% and 41% of the lakes in Europe, Africa, North America and South America have different degrees of eutrophication, and 54% of the lakes in ...
