Description
Technical Field
The invention relates to the field of preparation of bactericides for water treatment, in particular to a non-oxidizing bactericide applied to a double-membrane method circulating water treatment process and a preparation method thereof.
Background
Along with the increasing shortage of water resources, the industrial water is stressed, and the sewage recycling is particularly important, wherein the double-membrane method recycling technology is a hot spot for current research and application, and compared with a common double-membrane method system, the double-membrane method recycling technology comprises a desalted water system, a sewage recycling water system and a high-salt water system. The double-membrane method is a process combining different membrane technologies, has compact structure, small occupied area, low medicament consumption, stable treatment effect and safe and reliable operation management, can achieve the purposes of saving resources and reducing cost when being used for sewage regeneration, and has obvious economic and social benefits.
However, the microbial growth can be promoted for different water quality, water temperature and system environment, so that one of the most effective and most common methods for microbial growth in a double-membrane circulating cooling water system is to add bactericides. According to the principle of economy and practicality, the oxidizing bactericide is commonly used as a strong oxidant, and the aim of sterilization is mainly achieved through the oxidation with metabolic enzymes in bacteria. However, as the polyamide separation layer of the reverse osmosis membrane element in some double-membrane systems does not have oxidation resistance, the use of the oxidizing bactericide is limited, and the requirements for the non-oxidizing bactericide in the operation of more and more double-membrane systems are larger and more, so that the market share is high. Common non-oxidizing biocides are: quaternary ammonium salts, chlorophenols, organosulfur compounds, organotin compounds, organobromine compounds, isothiazolinones, glutaraldehyde, quaternary phosphonium salts, and the like. The non-oxidative germicides do not kill microorganisms by oxidation, but act as a toxicant on specific sites of microorganisms, thereby achieving the goal of killing microorganisms. CN107410358a discloses a non-oxidizing bactericide for water treatment, the formula of the patent comprises 1-10% by weight of isothiazolinone; 1-5% by weight glutaraldehyde; 10-50% by weight of water; 1-4% by weight sodium bromide; 1-6% by weight of organic bromine; 1-8% by weight of SQ8 bactericide; 1-5% by weight of dicyanomethane; 1-10% by weight of an organic amine bactericide. In summary, the patent publications all have the technical effects of remarkable difficulty in generating drug resistance, low toxicity, low environmental hazard and the like, but the bactericidal substances such as bromide, organic amine, glutaraldehyde and the like contained in the formula have the advantages that the bromide cost is high, peroxide and ozone are easy to decompose, glutaraldehyde is easy to react with ammonia or amine compounds and is invalid, so that the prepared non-oxidative bactericide has short bactericidal duration and low bactericidal efficiency.
