preparation example Construction

[0046] A preparation method for an inhibitor of Microcystis aeruginosa control, mainly comprising the following steps:

[0047] Step 1, picking and washing the leaves of Buxus poplar, drying them until the water content is 5-8%, and crushing the dried leaves to 50-100 mesh to obtain leaf powder of Box poplar;

[0048] Step 2, taking 5-10 parts by weight of the leaf powder of Populus cuspidatum and adding it into 500-1000 parts by weight of sterile distilled water, stirring evenly and heating to boiling for 1 hour, then suctioning and filtering the supernatant to obtain a crude leaf extract;

[0049] Step 3, adding 0.08-0.3 parts by weight of sodium carbonate to the leaf crude extract, stirring evenly, and filtering the precipitate to obtain a secondary leaf crude extract;

[0050] Step 4, adding 0.1-0.4 parts by weight of sodium nitrate and 0.08-0.3 parts by weight of flocculant to the crude extract of the secondary leaves, stirring until the sodium nitrate and flocculant are ...

Abstract

The invention discloses an inhibitor for microcystis aeruginosa control. The inhibitor is mainly prepared from the following raw materials in parts by weight: 75-90 parts of buxus sinica water extract, 3-8 parts of sodium nitrate, 3-5 parts of sodium carbonate and 3-5 parts of flocculant, and has a pH value of 8.5. The main component of the inhibitor is extracted from leaves of buxus sinica with low cost and quick response, has a remarkable effect for inhibiting microcystis aeruginosa, does not pollute the water body, and is safe and environment-friendly. Furthermore, in the preparation method of the inhibitor, the leaves of buxus sinica are dried, ground and extract, and are mixed with other raw materials, and the preparation method is simple and easy to understand, and is suitable for large-scale production and application. Furthermore, a certain amount of traditional Chinese medicinal ingredients are added into the inhibitor, so that the water can be sterilized and purified while the effect for inhibiting microcystis aeruginosa is improved.

Description

technical field [0001] The invention relates to the technical field of preparation of algae inhibitors, in particular to an inhibitor used for the control of Microcystis aeruginosa and its preparation method and use method. Background technique [0002] In recent years, in order to improve the cultural environment and enhance the city's taste, artificial lakes have become the primary choice in urban planning and development. However, after the artificial lake was built, human activities made the water body eutrophic, causing excessive algae growth, deteriorating water quality, and "water blooms", which not only failed to beautify life, but seriously affected people's life. Bloom algae such as Microcystis viridis, M. wesenbergii, Anabaena, Nostoc, Oscillatoria, etc. can also produce algal toxins, of which micro Cystin (MC) is the most widely distributed and most harmful toxin. It is hepatotoxic and can cause acute poisoning in animals and humans. Long-term exposure can induc...
