Abstract

The invention discloses a non-oxidized type compound bactericide for water treatment and a preparation method thereof. The non-oxidized type compound bactericide is prepared by the steps of weighing glutaraldehyde, acrylic acid-2-acrylamide-2-methyl propane sulfonic acid copolymer, tetradecyl benzyl dimethyl ammonium chloride, etidronic acid, water, PBTCA, a polymerization inhibitor, sulfonic acid, polyol phosphonate ester, PESA, a dispersant, sodium tungstate, bitertanol, sodium benzoate and acrylic acid-hydroxy-propyl acrylate copolymer in parts by weight, and mixing uniformly. The product is 100% water-soluble, and has a sterilizing rate of 99.9-100% to escherichia coli, staphylococcus aureus, candida albicans, neisseria gonorrhoeae, penicillium notatum, aspergillus, saprophytic bacteria and salmonella; and the sterilizing rate is 98-100% after the bactericide is placed for one month at 50-60 DEG C, the sterilizing rate is 97.9-99.9% after the bactericide is placed for half a year at 40-50 DEG C, and the sterilizing rate is 97.5-99.5% after the bactericide is placed for 1-2 years at room temperature.

Description

technical field [0001] The application belongs to the field of environmental protection reagent technology, and in particular relates to a non-oxidative compound bactericide for water treatment and a preparation method thereof which is non-toxic and has a remarkable bactericidal effect. Background technique [0002] Water treatment bactericide is also called bactericide and algicide, sludge stripper or anti-sludge agent. A class of chemicals that can inhibit the growth of bacteria, algae and microorganisms in water to prevent the formation of microbial slime and cause harm to the system. Including oxidizing fungicides, such as chlorine, sodium hypochlorite, bleaching powder, ozone, chloramine, etc.; non-oxidizing fungicides, such as dodecyl dimethyl benzyl ammonium chloride, dodecyl dimethyl benzyl bromide Ammonium, dithiocyanomethane, etc.; heavy metal compounds, such as mercuric oxide, mercuric chloride, mercuric fluoride, etc.; slime fungicides, such as rosin amine, hydr...
