Problems solved by technology

The disadvantage of this method is that it needs to invest in anti-ultraviolet radiation equipment, and sometimes it is necessary to add a catalyst. In addition, due to the nature of the cells themselves, sometimes they cannot be killed by ultraviolet rays, which will cause variation and cause more serious pollution; oxidative sterilization is harmful to bacteria and algae. It has a very good effect, but if there is an operation problem, it is easy to cause the oxidant to enter the cooling system and cause irreversible damage to the cooling pipe; the toxicological sterilization effect on bacteria and algae is very obvious. If a single use of fungicides will affect the circulating cooling water The system causes secondary pollution, but if the fungicides are properly proportioned, the circulating cooling water system will not cause secondary pollution when the fungicides are used

Embodiment 1

[0028] 2g sulfamic acid is dissolved in 10g deionized water earlier in the compound bactericidal algicide process of preparing the present invention, then in sulfamic acid solution, add 40g dodecyl dimethyl benzyl ammonium chloride, through conventional stirring Make it mix evenly to form a mixed solution, then add 30g of glutaraldehyde into the mixed solution, and make it mix evenly through conventional stirring.

Embodiment 2

[0030] 4g sulfamic acid is dissolved in 13g deionized water earlier in the compound bactericidal algicide process of preparing the present invention, then in sulfamic acid solution, add 50g dodecyl dimethyl benzyl ammonium chloride, through conventional stirring Make it mix evenly to form a mixed solution, then add 40g of glutaraldehyde into the mixed solution, and make it mix evenly through conventional stirring.

Embodiment 3

[0032] 5g sulfamic acid is dissolved in 15g deionized water earlier in the compound bactericidal algicide process of preparing the present invention, then in sulfamic acid solution, add 60g dodecyl dimethyl benzyl ammonium chloride, through conventional stirring Make it mix evenly to form a mixed solution, then add 50g of glutaraldehyde into the mixed solution, and make it mix evenly through conventional stirring.

[0033] Above-mentioned embodiment carries out sterilizing performance comparative experiment with bactericides such as glutaraldehyde, lauryl dimethyl benzyl ammonium chloride, organic bromide, and test result is as follows:

[0034]

[0035] The above comparative experiments can be obtained that the bactericidal algicide according to the present invention has a better bactericidal effect than a single agent when the same dosage is used, and the ratio of the embodiment 2 has a better bactericidal effect.

[0036] The slime stripping experiment was carried out us...

Abstract

The invention relates to the technical field of industrial circulating water treatment, and in particular relates to a complex germicidal and algicidal agent. The complex germicidal and algicidal agent is characterized by consisting of the following components in parts by weight: 30-50 parts of glutaraldehyde, 40-60 parts of dodecyl dimethyl benzyl ammonium chloride, 2-5 parts of aminosulfonic acid and 10-15 parts of de-ionized water. The complex germicidal and algicidal agent, in comparison with a simple agent, has a beneficial effect that the germicidal and algicidal agent has a remarkable germicidal and algicidal effect, and in comparison with an existing corresponding germicide, the complex germicidal and algicidal agent, which is prepared from dodecyl dimethyl benzyl ammonium chloride, glutaraldehyde and aminosulfonic acid, is low in dosage, more excellent in germicidal effect, and more remarkable in sludge stripping effect due to addition of the aminosulfonic acid; and the germicidal and algicidal agent is free from secondary pollution to a circulating cooling system on the premise that various components are within use concentration range. The complex germicidal and algicidal agent is simple to prepare, low in dosage, low in cost, and good in germicidal, algicidal and sludge stripping effects.

Description

technical field [0001] The invention relates to the technical field of industrial circulating water treatment, in particular to a compound bactericide and algicide. Background technique [0002] With the rapid development of the economy and the increasingly serious environmental pollution, the problem of water shortage and water quality deterioration has become increasingly prominent, and water conservation has become a relatively large issue. The existing better method is to recycle cooling water, but due to industrial discharge The quality of the water is different, so that the water cannot be recycled directly, and must go through a series of treatment processes before it can be used in production again. [0003] With the continuous advancement of water treatment technology, the application of cooling circulating water has become popular. Since cooling circulating equipment is mostly made of steel or copper, preventing the cooling system from being damaged by bacteria and...
