Embodiment 1

[0019] An industrial water treatment fungicide consists of three components: alkyl quaternary phosphonium salt, quaternary ammonium salt, and tributyltin chloride, in parts by mass:

[0020] 30 parts of alkyl quaternary phosphorus salt

[0021] 25 parts of quaternary ammonium salt

[0022] 8 parts of tributyltin chloride

[0023] In this embodiment, the alkyl quaternary phosphorus salt is tetradecyl tributyl phosphorus chloride.

[0024] In this embodiment, the quaternary ammonium salt is dodecyl dimethyl benzyl ammonium chloride.

Embodiment 2

[0026] An industrial water treatment fungicide consists of three components: alkyl quaternary phosphonium salt, quaternary ammonium salt, and tributyltin chloride, in parts by mass:

Abstract

An industrial water treatment bactericide consists of three ingredients of alkyl quaternary phosphonium salt, quaternary ammonium salt and tributyltin chloride, wherein the alkyl quaternary phosphonium salt is one of or a composition of tributyltetradecylphosphonium chloride and tetrakisphosphonium sulfate; the quaternary ammonium salt is one of or a composition of dodecyl dimethyl benzyl ammonium chloride and 12-alkyl dimethyl ammonium chloride.

Description

technical field [0001] The invention belongs to the field of water treatment agents, in particular to a fungicide for industrial water treatment. Background technique [0002] With the development of the world economy and society, the problem of water resources is becoming more and more serious, and solving the problem of water resource shortage has become a common topic worldwide. China's fresh water only accounts for 7% of the world's total. In order to achieve sustainable economic development, industrial water treatment and recycling are necessary. The pollution of industrial circulating water system is mainly caused by microorganisms. The formation of organic deposits in industrial circulating water systems is mainly caused by the growth of microorganisms. Microorganisms in circulating water generally refer to bacteria and algae. In fresh water, there are fewer bacteria and algae, but in circulating water, due to the concentration and enrichment of nutrients, the rise...
