Environmentally-friendly biocide and preparation method thereof

Abstract

The invention relates to the technical field of water processing, and especially relates to an environmentally-friendly biocide and a preparation method thereof. The biocide comprises, by weight, 20-40 parts of isothiazolinone, 10-25 parts of glutaraldehyde, 8-12 parts of benzylhexadecyldimethylammonium chloride and 80 parts of distilled water. Compared with traditional biocides, the biocide of the invention has the characteristics of excellent environment performance, environmental protection benefiting because of discontinuous existence in the environment, high biological killing efficiency, good degradability, no residual generation, safe operation, good compatibleness, strong stability, low use cost and the like.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an environment-friendly biocide and a manufacturing method thereof. Background technique [0002] The environment of the circulating cooling water system provides excellent conditions for the reproduction of microorganisms. Water temperature suitable for microbial growth (generally 25-40°C); saturated dissolved oxygen; moderate Ph value; rich nutrient sources (N, P, C, etc.); increased concentration ratio and increased salt content; process medium Leakage; addition of chemicals; a large number of bacteria in the air and water; and sufficient sunlight all create an ideal environment for the growth of microorganisms in circulating cooling water. Therefore, it is inevitable for microorganisms to reproduce in large numbers in circulating water. However, the harm caused by microorganisms to circulating water is extremely great. A large amount of slime produced by it causes i...

Problems solved by technology

However, the harm caused by microorganisms to circulating water is extremely great. A large amount of slime produced by it causes induced corrosion in circulating water, and the slime covers the metal anode, resulting in oxygen concentration corrosion of the battery, and iron is dissolved; Aggregation, scaling, impeding heat conduction, serious blockage of pipes, increased energy consumption, and deterioration of water quality
