Abstract

The invention belongs to the technical field of algae removal and particularly relates to a preparation method of an environment-friendly algicide. The preparation method comprises the following steps: firstly, treating towel gourd vegetable sponge with hydrogen peroxide to reduce the content of crude fibers inside the towel gourd vegetable sponge; secondly, mixing the treated towel gourd vegetable sponge with acrylic acid, polyglutamic acid, N,N-methylene bisacrylamide and the like, and using potassium peroxodisulfate as an initiator to obtain towel gourd vegetable sponge-supported degradable super absorbent resin; thirdly, extracting algae removing enzyme inside neocaridina denticulate and algae removing beneficial substances in fructus xanthii and radix stemonae; mixing a carrier with extracts, and adsorbing beneficial substances in the extracts; and meanwhile, adding urea for mixing to obtain the environment-friendly algicide. The algicide prepared by the preparation method disclosed by the invention has the characteristics of stability, high removal efficiency and environment friendliness; after the environment-friendly algicide is put into a water body and is used for 40 to 60 minutes, harmful algae in the water body can be settled to the water bottom, and the algae removal rate reaches 96.2 percent or above; and in addition, after the algicide is used, secondary pollution to the water body is avoided.

Description

technical field [0001] The invention belongs to the technical field of algae removal, and in particular relates to a preparation method of an environment-friendly algae removal agent. Background technique [0002] In recent years, the eutrophication of water bodies has become very serious, and it has become a major problem in the environmental field that needs to be solved urgently. Algae flooding in rivers, lakes and seas has attracted widespread attention. Large-scale algae outbreaks have seriously damaged the balance and stability of aquatic ecosystems, not only affecting water landscapes, but also affecting the development of aquaculture. Moreover, algae toxicity has constituted a threat to human survival. environmental threats. Therefore, how to control and eliminate the explosive growth of harmful algae in eutrophic water bodies is currently a research hotspot and frontier in the field of water environment. [0003] At present, the more popular algae removal methods ...
