Abstract

The invention relates to the technical field of water treatment, in particular to a non-oxidizing bactericide for water treatment. The non-oxidizing bactericide for water treatment comprises the following components in percentages by weight: 1-10% of isothiazolinone, 1-5% of glutaraldehyde, 10-50% of water, 1-4% of sodium bromide, 1-6% of organic bromide, 1-8% of a SQ8 bactericide, 1-5% of methylene dioxycyanate and 1-10% of an organic amines bactericide. The invention provides the non-oxidizing bactericide for water treatment. In the non-oxidizing bactericide for water treatment, several substances are compounded according to a certain mass ratio, the circulating water sterilizing effect of the compounded substances is obviously higher than that of independently used one of the several substances, chemical agent resistance cannot be caused easily, the toxicity is small, the environmental hazard is low, and therefore, the non-oxidizing bactericide for water treatment is a bactericide which meet the requirement of sustainable development.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a non-oxidizing fungicide for water treatment. 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 peroxide, and guanidine polymers, etc. [0003] The non-oxidative bactericidal algicide in the water treatment fungicide does not ...
