Algicide production method based on moss extraction liquid and application of algicide

Abstract

The invention discloses an algicide production method based on moss extraction liquid and application of algicide. Traditional algal inhibition methods mainly comprise a physical method, a chemical method and a biological method, however, all the methods have the disadvantages that the cost is high, ecological hazards are large, and the like. The algicide production method based on the moss extraction liquid comprises the following steps of (1) taking moss for grinding and crushing, and drying the moss to a constant weight to obtain moss powder; (2) dividing the moss powder into two parts, andperforming separate extraction by using an ethanol solution and deionized water to obtain an ethanol extract and a deionized water extract; (3) concentrating and filtering the ethanol extract to obtain concentrated paste; (4) adding the concentrated paste into the deionized water extract to obtain moss mixed extraction liquid; (5) conducting centrifugal shearing treatment on the moss mixed extraction liquid, and mixing the material subjected to centrifugal shearing treatment and a sodium alginate solution to obtain an algal inhibition core solution; (6) producing an inorganic forming agent; and (7) adding the algal inhibition core solution into the inorganic forming agent to obtain the algicide. According to the algicide production method based on the moss extraction liquid, the moss extraction liquid is adopted as a raw material for producing the algicide, so that the algicide has small effects on water bodies, and is liable to be degraded.

Description

technical field [0001] The invention belongs to the technical field of algae inhibitors, and in particular relates to a method for preparing an algae inhibitor based on a moss extract and an application thereof. Background technique [0002] In recent years, the phenomenon of eutrophication in water bodies has intensified, resulting in frequent occurrence of algal blooms. The algae in the waters where the algal blooms explode consume a large amount of dissolved oxygen in the water, causing a large number of aquatic organisms to die, which not only seriously deteriorates the water quality, destroys the balance and self-regulation ability of the ecosystem, but also produces and releases toxins to the water body. These highly toxic algal secretions not only poison aquatic organisms, affect fishery production, but even pass through the food chain, threatening human health. The economic loss caused by a serious algae bloom or red tide exceeds several million dollars, and there a...

Problems solved by technology

While phytoallelopathy inhibits algae, it can significantly reduce the content of algae toxins in water, which is impossible by other methods. The final results of other methods are very likely to release a large amount of algae toxins, which will pose a threat to drinking water safety. great threat
