Abstract

The invention discloses a water treatment ternary copolymerization bactericide and a preparation method thereof. The preparation method comprises the following steps: weighing glutaraldehyde, AMPS, crylic acid, isopropanol, water, sodium hydroxide, a polymerization inhibitor, sodium hypophosphite, maleic anhydride, ammonium persulfate, a dispersing agent, phosphorus trichloride, N,N-dimethylformamide, L-aspartic acid and glutamic acid according to parts by weight, and uniformly mixing the materials to prepare the bactericide. The scale inhibiting ratio of the bactericide is 85.5-98.5%; the density is 1.15-1.35 g / cm<2>; after the bactericide is stored at 50-60 DEG C for one month, the bactericidal rate is 98.5-99.5%; after the bactericide is stored at 40-50 DEG C for half a year, the bactericidal rate is 97-99%; after the bactericide is stored at the room temperature for 1-2 years, the bactericidal rate is 96-98%; when the bactericide is applied to escherichia coli, staphylococcus aureus, streptococcus albus, gonococcus, penicillium, aspergillus, saprophytic bacteria and salmonella, the bactericidal rate is 98.8-99.8%.

Description

technical field [0001] The application belongs to the field of environmental protection reagent technology, and in particular relates to a non-toxic, tertiary copolymerization bactericide for water treatment with remarkable bactericidal effect and a preparation method thereof. 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, hydrogen perox...
