Problems solved by technology

[0003] The single fungicides currently used in my country are mainly hypochlorous acid, quaternary ammonium salts, organic sulfur compounds, hybrid compounds and other fungicides, among which quaternary ammonium salts are highly efficient and low-toxic, and can kill sulfate-reducing bacteria growing under slime , and has good synergistic performance with other water treatment agents, strong stability to chlorine, and effective corrosion and scale inhibition, low phosphine content, less environmental pollution and no emission restrictions; Large, and the organisms are prone to drug resistance and cannot have an obvious bactericidal effect, so a variety of fungicides are required to be used in combination in order to have a more obvious synergistic effect

Abstract

The invention relates to the technical field of chemical engineering, and relates to a bactericide for petrochemical circulating water, and in particular relates to a compound bactericide which can be used for remarkably reducing corrosion of a petrochemical circulating water pipeline and reproduction of phycomycetes. The bactericide mainly consists of organic alkali, pypocholoride, a surfactant, alkyl benzyl ammonium chloride and water which are uniformly mixed. The bactericide in the proportion has a remarkably inhibiting effect and sterilizing property on microorganisms such as sulfate reducting bacteria and iron bacteria of a using system, can be used for remarkably reducing the general amount of bacteria in the circulating water, that is to say, prolonging the service life of equipment, improving the repeating utilization factor of the cooling water and reducing the consumption of water resources.

Description

technical field [0001] The invention relates to the technical field of chemical industry, and relates to a cooling water composite fungicide, in particular to a high-efficiency composite fungicide capable of significantly reducing the number of bacteria in the cooling water of a petrochemical system and inhibiting the reproduction of microorganisms. Background technique [0002] In the petrochemical industry, circulating cooling water accompanies the whole process of production, accounting for 70% to 80% of the total water consumption. Due to the continuous evaporation and concentration of the circulating cooling water, the scale and corrosion of the circulating cooling water are relatively serious, and it is easy to breed bacteria and algae, which will affect the heat transfer effect of the equipment and reduce the service life of the equipment. Therefore, to improve the reuse rate of industrial water, it is necessary to carry out water quality treatment on circulating cool...
