Problems solved by technology

Algae inhibitors can be divided into physical algae inhibitors, chemical algae inhibitors and biochemical algae inhibitors. The properties of these algae inhibitors are as follows: 1) Physical algae inhibitors: the effect of algae inhibition is remarkable, but it takes a long time It takes time to take effect, and metal ions such as iron and aluminum will be introduced into the water body. Although the pollution is low, there is still pollution; 2) Chemical algicide: quick effect, and it is also toxic to aquatic organisms while killing algae. There is a hidden danger of secondary pollution; 3) Biological algicide: low toxicity and low cost, so it has become the research direction of current water environment treatment technology
[0004] The existing biological algicides either have an inhibition rate below 50%, or use a large amount of algaecides

preparation example Construction

[0024] The invention provides a method for preparing an algastatic agent from Luo Han Guo extract, the preparation method comprising:

[0025] a, crushing Luo Han Guo to make Luo Han Guo powder;

[0026] b. Mixing Luo Han Guo powder, alcohol and water to prepare Luo Han Guo suspension;

[0027] c. Concentrating the Luo Han Guo suspension to prepare the algae inhibitor of Luo Han Guo extract.

[0028] In the preparation method provided by the present invention, the particle size of Luo Han Guo powder can be selected in a wide range, but in order to make the algae inhibitor of the prepared Luo Han Guo extract have a more excellent effect of inhibiting algae growth, preferably, Luo Han Guo powder The particle size is not less than 150 mesh.

[0029] In the preparation method provided by the present invention, the consumption of Luo Han Guo powder and water can be selected in a wide range, but in order to make the prepared Luo Han Guo extract liquid algicide have a more excellen...

Embodiment 1

[0038] a, smashing Luo Han Guo and passing through a 150-mesh sieve to obtain Luo Han Guo powder;

[0039] b. Soak the Luo Han Guo powder in water for 3 days at 25°C to prepare the Luo Han Guo suspension; wherein, the mass ratio of the Luo Han Guo powder to the aqueous solution is 1:20.

[0040] c. Concentrate the above-mentioned Monk Fruit suspension until the solid-to-liquid weight ratio is 1:10 to prepare Monk Fruit extract algae inhibitor A1.

Abstract

The invention discloses an algae inhibitor of Luo Han Guo extract and its preparation method and application. The preparation method comprises: a. crushing Luo Han Guo to make Luo Han Guo powder; b. mixing Luo Han Guo powder, alcohol and water to prepare Luo Han Guo suspension turbid liquid; c, concentrating the Luo Han Guo suspension to obtain the algae inhibitor of Luo Han Guo extract. The algae-inhibiting agent prepared by the method can effectively inhibit the growth of algae.

Description

technical field [0001] The invention relates to an algae inhibitor, in particular to an algae inhibitor from Luo Han Guo extract and its preparation method and application. Background technique [0002] Algae bloom is a disaster phenomenon that frequently occurs in seawater and freshwater waters. It is called red tide in the ocean and algae bloom in freshwater. The algae that can form water blooms are mainly species in Cyanophyta and Chlorophyta. In eutrophic freshwater, Microcystis aeruginosa and Anabaena are the most common cyanophyta. [0003] Preventing and controlling algal blooms has become a top priority. Algae inhibitors can quickly exert their anti-algae effect to relieve water blooms, so they have become one of the emergency treatment methods for water blooms. Algae inhibitors can be divided into physical algae inhibitors, chemical algae inhibitors and biochemical algae inhibitors. The properties of these algae inhibitors are as follows: 1) Physical algae inhibi...
