Embodiment 1

[0027] The fungicide includes the following components by weight: 15 parts of isothiazolinone, 2 parts of copper sulfate, 6 parts of dodecyldimethylbenzyl ammonium bromide, 3 parts of water-soluble sterol oil, diiodomethyl p-formaldehyde 4 parts of phenyl sulfone, 90 parts of water, 15 parts of ethanol, 0.075 part of fluorinated alkyl phosphate and 0.04 part of sodium tripolyphosphate;

[0028] The preparation method of the bactericide is as follows: 1) 90% water is taken from the total water and added into the reaction kettle, and ethanol, isothiazolone, copper sulfate, dodecyldimethylbenzyl ammonium bromide, Water-soluble sterol oil, diiodomethyl p-methylphenyl sulfone, fluorinated alkyl phosphate and sodium tripolyphosphate are pumped into the reactor, and finally the remaining water is pumped into the reactor; 2) The materials are stirred for 35 minutes after pumping , when the mixed solution is clear and transparent, the bactericide is prepared.

Embodiment 2

[0030] The fungicide includes the following components by weight: 10 parts of isothiazolinone, 1 part of copper sulfate, 2 parts of dodecyldimethylbenzyl ammonium bromide, 1 part of water-soluble sterol oil, diiodomethyl p-formaldehyde 2 parts of phenyl sulfone, 80 parts of water, 10 parts of ethanol, 0.05 part of fluorinated alkyl phosphate and 0.02 part of sodium tripolyphosphate;

[0031] The preparation method of the bactericide is as follows: 1) 90% water is taken from the total water and added into the reaction kettle, and ethanol, isothiazolone, copper sulfate, dodecyldimethylbenzyl ammonium bromide, Water-soluble sterol oil, diiodomethyl-p-tolylsulfone, fluorinated alkyl phosphate and sodium tripolyphosphate are pumped into the reactor, and finally the remaining water is pumped into the reactor; 2) The materials are stirred for 30 minutes after pumping , when the mixed solution is clear and transparent, the bactericide is prepared.

Embodiment 3

[0033] The fungicide includes the following components by weight: 20 parts of isothiazolinone, 3 parts of copper sulfate, 10 parts of dodecyl dimethyl benzyl ammonium bromide, 5 parts of water-soluble sterol oil, diiodomethyl p-formaldehyde 6 parts of phenyl sulfone, 100 parts of water, 20 parts of ethanol, 0.1 part of fluorinated alkyl phosphate and 0.06 part of sodium tripolyphosphate;

[0034] The preparation method of the bactericide is as follows: 1) 90% water is taken from the total water and added into the reaction kettle, and ethanol, isothiazolone, copper sulfate, dodecyldimethylbenzyl ammonium bromide, Water-soluble sterol oil, diiodomethyl p-methylphenyl sulfone, fluorinated alkyl phosphate and sodium tripolyphosphate are pumped into the reactor, and finally the remaining water is pumped into the reactor; 2) The materials are stirred for 40 minutes after pumping , when the mixed solution is clear and transparent, the bactericide is prepared.

Abstract

The invention relates to a water treatment bactericide and relates to the technical field of water treatment. The water treatment bactericide is prepared from the following components in parts by weight: 10 to 20 parts of isothiazolinone, 1 to 3 parts of copper sulfate, 2 to 10 parts of dodecyl dimethyl benzyl ammonium bromide, 1 to 5 parts of water-soluble sterol oil, 2 to 6 parts of diiodomethylp-methyl phenyl sulfone, 80 to 100 parts of water, 10 to 20 parts of ethanol, 0.05 to 0.1 part of an antifoaming agent and 0.02 to 0.06 part of a stabilizing agent. The water treatment bactericide has the effect of improving the defect of low sterilization rate of a single non-oxidizing bactericide.

Description

technical field [0001] The present application relates to the technical field of water treatment, in particular to a water treatment bactericide. Background technique [0002] The circulating water system is a special and complex ecological environment, which is suitable for the growth of various microorganisms. The growth of microorganisms will cause the cooling tower pool to be covered with green algae, and a large amount of slime will be generated inside the cooling water pipe. Algae and slime will cause blockage and corrosion of equipment pipes, affect the heat transfer efficiency of the heat exchanger and lead to deterioration of water quality. Huge economic losses have been caused to industrial production. Therefore, bactericides are usually used in circulating water systems to kill or inhibit the growth of microorganisms. [0003] Water treatment fungicides are a class of chemicals that can inhibit the growth of bacteria, algae and microorganisms in water to prevent...
