Chinese herbal medicine algaecide as well as preparation method and application thereof

Abstract

The invention discloses Chinese herbal medicine algaecide as well as a preparation method and an application thereof. The preparation method comprises the following steps: a, soaking radix glycyrrhizae in water and then filtering to obtain radix glycyrrhizae leaching liquor; b, soaking momordica grosvenori in water and then filtering to prepare Momordica grosvenori leaching liquor; c, mixing the radix glycyrrhizae leaching liquor with the momordica grosvenori leaching liquor to prepare the Chinese herbal medicine algaecide. The Chinese herbal medicine algaecide prepared by the preparation method disclosed by the invention has a high inhibition ratio and low dosage.

Description

technical field [0001] The invention relates to a Chinese herbal medicine anti-algae agent, a preparation method thereof and an application of the Chinese herbal medicine anti-algae agent in inhibiting the growth of algae. 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 i...

AI Technical Summary

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
