Problems solved by technology

The Japanese garden test formula is more general, but it still cannot avoid the growth of green algae in the nutrient solution
Although the green algae can be fished out from the water through the filter device and centrifuged, this method is costly and requires constant replacement of the filter element; and the ultraviolet germicidal lamp can also be sterilized, but it will increase energy consumption and is uneconomical; Although the use of algicides to kill algae is an exploration, and the common polyaluminum chloride is effective in purifying pond water, but aluminum can cause damage to the brain and nervous system, so it cannot be directly used in the nutrient solution of hydroponic plants

Embodiment 1

[0021] Select BG11 pre-cultured mother liquor of C. serrata (the algal species are provided by the freshwater algae library of the Institute of Hydrobiology, Chinese Academy of Sciences), the initial OD value is 0.8, and the initial algae density is about 0.0742*10 7 / mL (algal cells per milliliter). Slightly acidic electrolyzed water (pH value of 5.6-6.0, redox potential ORP of 750-800mv) with a final concentration of ACC of 0, 10, 20, 30, and 40 mg / L was used to treat the algal liquid, and the algal liquid was passed through a shaker (rotation speed 100- 200r / min) for 15S, and after the treatment, use a final volume of 10% with a concentration of 0.05% Na 2 S 2 O 3 Terminate the reaction. Ensure that the total volume of the Erlenmeyer flask for each treatment group is 100ml. After the treatment reaction was completed, the cells were cultured under artificial light plate for 24 hours, and then placed in a constant temperature shaker for 11 days.

Abstract

The invention provides a method for treating green algae based on slightly acidic electrolyzed water. The method of the present invention selects to use slightly acidic electrolyzed water as the treatment agent, which has strong redox effect, and at the same time, it will be reduced to water after interacting with the tested organism, and will dissipate quickly without causing the problem of disinfectant residue. Compared with traditional treatment agents, slightly acidic electrolyzed water is more efficient and safe, friendly to the human body and the environment, and will not cause secondary pollution; it is also conducive to the maintenance of factory production equipment and the environment. Relevant studies have shown that slightly acidic electrolyzed water will not carry microorganisms after sterilization, and its chemical properties will not change much, and it still has a good sterilization effect. It can be recycled within a certain period of time.

Description

technical field [0001] The invention relates to the technical field of environmental algal bloom treatment, in particular to a green algae treatment method based on slightly acidic electrolyzed water. Background technique [0002] With the increasing development and utilization of environmental resources by human beings, especially in the 20th century, industrialized production and urban development are mainly concentrated in some specific areas with rich water sources, and a large amount of industrial wastewater and domestic sewage containing N, P and other nutrients are discharged. To nearby lakes, rivers and reservoirs, the load of nutrients in these water bodies is increased; at the same time, the extensive use of chemical fertilizers and pesticides in agricultural production has resulted in a large number of nutrients that have not been absorbed by crops being washed and infiltrated by rainwater, and finally transported to In addition, livestock manure in animal husband...
