Embodiment 1

[0013] Embodiment 1 A kind of sterilizing and algae-killing stripping agent for circulating water, the addition amount according to the volume of circulating water: isothiazolinone: 0.5%wt; Copper sulfate: 0.1%wt Dodecylbenzyl ammonium chloride: 15%wt; Glutaraldehyde: 3%wt; sulfuric acid: 0.015%wt; the balance is water.

[0014] Preparation method: Convert the above-mentioned raw materials with different concentrations in the market into pure products, weigh them according to the above-mentioned proportions, and add them to the reaction kettle. The copper sulfate needs to be dissolved in water and then added, and stirred slowly. After stirring evenly, let it stand until the foam disappears into a plastic container.

[0015] How to use: Before use, change the water in large quantities to reduce the concentration ratio of the circulating cooling water as much as possible, and maintain the highest water level. According to the amount of bacteria and algae in the circulating cooli...

Embodiment 2

[0016] Embodiment 2 A kind of sterilizing and algae-killing stripping agent for circulating water, the amount added according to the volume of circulating water: isothiazolinone: 0.5%wt; copper sulfate: 0.5%wt dodecylbenzyl ammonium bromide: 35%wt; Glutaraldehyde: 10%wt; sulfuric acid: 0.025%wt; the balance is water.

Embodiment 3

[0017] Embodiment 3 A sterilizing and algae-killing stripping agent for circulating water, the amount added according to the volume of circulating water: isothiazolinone: 3%wt; copper sulfate: 0.3%wt dodecylbenzyl ammonium chloride: 25%wt; Glutaraldehyde: 5%wt; sulfuric acid: 0.020%wt; the balance is water.

Abstract

The invention mainly relates to a sterilization and alga-killing remover and application of the in treating circulating water. The sterilization and alga-killing remover for the circulating water is characterized by comprising the following compositions in percentage by weight: 0.5 to 3 wt percent of isothiazolinone, 0.1 to 0.5 wt percent of bluestone, 10 to 35 wt percent of chlorine or dodecyl dimethyl benzyl ammonium bromide, 0 to 10 wt percent of glutaraldehyde, 0.015 to 0.025 wt percent of sulphuric acid and the balance of water. The sterilization and alga-killing remover is a non-oxidizing type disinfectant, is used for a circulating water system, has the functions of sterilization and alga removal and the function of removing alga and sludge from the surface of equipment, is fed by adopting an impact type mode and has the characteristics of quick effect, thorough sterilization and the like.

Description

technical field [0001] The invention mainly relates to a sterilizing and algae-killing stripping agent and its application in circulating water treatment. Background technique [0002] The temperature of the circulating cooling water is in the range of 10-40℃ all the year round, and it is sunny and rich in nutrients, which is a favorable environment for the growth and reproduction of microorganisms. The proliferation of microorganisms brings hidden dangers to the operation of the circulating water system. [0003] Microorganisms in circulating water can be controlled in different ways depending on their growth conditions. Such as preventing sunlight, increasing the temperature of water, using side-flow filtration, and pre-treating supplementary water, etc., but the most commonly used recently is to add biocides. [0004] According to the biocidal mechanism, it can be divided into two categories: oxidizing and non-oxidizing biocides, such as Cl 2 , NaClO, O 3 , ClO 2 Chl...
