Problems solved by technology

However, its treatment cost is higher than that of oxidative bactericide and algicide, and it is easy to cause environmental pollution, and microorganisms in water are prone to produce drug-resistant forms
In addition, there are some compound modified bactericides and algicides with more ingredients, and the preparation process is correspondingly complicated, which is not suitable for large-scale application, and the cost is relatively high.

Embodiment 1

[0022] A preparation method of a power plant bactericidal algicide is characterized in that it comprises the following steps:

[0023] (1) The weight ratio is 1% of trimethylamine, 0.1% of oxychloropropane, 25% of 12 / 14 tertiary amine, the quaternary tetrakis hydroxymethyl phosphorus sulfate, and its mass ratio is 1:1.2-1.8, 1%, isothiazole Phosphoketone 03%, stirring;

[0024] (2) Place 1% hydrochloric acid and remainder deionized water in the uniformly stirred product described in step (1), so that its pH value is 7.

[0025] (3) inspection canning of the product obtained in step (2).

Embodiment 2

[0027] A preparation method of a power plant bactericidal algicide is characterized in that it comprises the following steps:

[0028] (1) The weight ratio is 25% of trimethylamine, 10% of chloropropane oxide, 10% of 12 / 14 tertiary amine, 1% of tetradecyl tributyl phosphorus chloride, and 10% of dodecyl tributyl phosphorus chloride , its mass ratio is 1:1.2, isothiazolone 4%, stirs;

[0029] (2) 4% hydrochloric acid and remainder deionized water are placed in the uniformly stirred product described in step (1), so that its pH value is 8.

[0030] (3) inspection canning of the product obtained in step (2)

Embodiment 3

[0032] A preparation method of a power plant bactericidal algicide is characterized in that it comprises the following steps:

[0033] (1) The weight ratio is 30% of trimethylamine, 15% of chloropropane oxide, 20% of 12 / 14 tertiary amine, 1-25% of dodecyl tributyl phosphorus chloride, 4% of isothiazolone, and carry out stir;

[0034] (2) Place 6% hydrochloric acid and remainder deionized water in the uniformly stirred product described in step (1), so that its pH value is 6.

Abstract

The invention discloses a sterilization algicide for power plants and a preparation method of the sterilization algicide, and belongs to the field of environment treatment. The power plant sterilization algicide with good stability comprises the following raw materials in parts by weight, 1-30% of trimethylamine, 0.1-15% of chloropropane oxide, 1-25% of 12 / 14 tertiary amine, 1-25% of a quaternaryphosphonium salt, 0.5-8% of isothiazolinone, 1-10% of hydrochloric acid and balance of deionized water.. The preparation method is simple, easy to operate, capable of achieving industrialization, goodin using effect and free of harm to the human body and secondary pollution.

Description

technical field [0001] The invention relates to the field of beverages, and in particular to a bactericidal algicide for power plants and a preparation method thereof. Background technique [0002] In the circulating cooling water system of waste incineration power plants, a suitable living environment and sufficient nutrients are conducive to the proliferation of microorganisms, and biological slime such as rubbery deposits, sticky substances, gelatinous films or colored slime groups are produced. class of substances. Due to the fast adhesion of slime (the amount of adhesion can reach several millimeters within a month), the thermal efficiency of the circulating cooling water system will be reduced, which is even more serious than the reduction in thermal efficiency caused by corrosion products and attached scale. Specifically, slime is easy to deposit on the metal surface, especially in the high-temperature and low-velocity areas of the water circulation system. In additi...
