Problems solved by technology

[0004] The existing algaecides have incomplete dehydration function and are easy to pollute the water body, which is not only unfavorable for the growth of fish, shrimp, and crabs, but also seriously threatens the health of fish, shrimp, and crabs, and then threatens human life and health. Therefore, It is imminent to develop an algaecide that can not only completely remove algae, but also reduce water pollution, effectively increase the concentration of trace elements in water, and promote the healthy growth of fish, shrimp, and crabs.

Abstract

The invention discloses a multifunctional slow-release algaecide which is composed of the following components in parts by weight: 30-100 parts of biodegradable polymer, 6-15 parts of yeast polypeptide, 1-2 parts of ethoxylated fatty acid methyl ester, 3-8 parts of pine needle extract, 1-10 parts of sodium polyacrylate, 1-4.2 parts of carfentrazone-ethyl, 0.5-3 parts of alkyl ether sulfate and 10-22 parts of hectorite powder. The yeast polypeptide, pine needle extract and carfentrazone-ethyl can inhibit the growth of algae. The hectorite powder dissolved in water can form a gel, and the gel has the advantages of favorable suspension stability, stable chemical properties and no toxicity. The ethoxylated fatty acid methyl ester has favorable surface activity and cleaning function. By utilizing the slow-release action of the biodegradable polymer, after the algaecide is added into a water body, the alga removal component can not be quickly diluted by water, so the local concentration of the packed algaecide is higher. Besides, the algaecide has high safety, and can reduce the water body pollution.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a multifunctional slow-release algicide. Background technique [0002] A large amount of domestic sewage and industrial wastewater rich in N and P are discharged into rivers and lakes, and then collected into the ocean, causing eutrophication of the water body, causing algae and other plankton to multiply rapidly and causing serious environmental disasters. It occurs frequently in various lakes, rivers and sea areas in my country. The massive reproduction of algae not only seriously hinders the water surface traffic, but also seriously damages the water environment and endangers the safety of the ecological environment. [0003] After long-term research and practice, three main types of algae removal technologies have been formed by means of physics, chemistry and biology. Physical methods can be divided into removal method and killing method. The former is to d...
