Embodiment 1

[0023] JY-9100 Bactericidal algaecide consists of 1,3-dibromo-5,5-dimethylhydantoin 30%, trichlorinated isocyanuric acid 30%, NaHCO 3 10%, Mg(NO 3 ) 2 20%, water 10% composition.

Embodiment 2

[0025] JY-9101 Bactericidal algicide consists of 1-bromo-3-chloro-5,5-dimethylhydantoin 35%, sodium dichloride isocyanurate 35%, KNO 3 10%, MgCl 2 10%, water 10% composition.

Embodiment 3

[0027] JY-9102 Bactericidal algaecide consists of 3-bromo-1-chloro-5,5-dimethylhydantoin 40%, potassium dichloride isocyanurate 20%, NaCl 15%, MgSO 4 10%, water 15% composition.

[0028] The composite bactericide and algaecide of above-mentioned type obtained is diluted with water, and the use effect of the present invention is illustrated by the following tests. (The control fungicide is dodecyl dimethyl benzyl ammonium chloride (commonly known as 1227))

Abstract

The invention belongs to the technical field of production and application of water-treating agents, and in particular relates to a slow-release type composite sterilization algicide. The slow-release type composite sterilization algicide comprises the following components in percentage by weight: 20 to 50 percent of bromine hydantoins, 20 to 40 percent of isocyanuric acid oxidants, 10 to 20 percent of stabilizer, 10 to 20 percent of bonding agent and 10 to 20 percent of water. The preparation method comprises the following steps of: dissolving the isocyanuric acid oxidants, the stabilizer and the bonding agent into water in proportion; mixing the mixture, adding the bromine hydantoins to the mixture in proportion, and mixing the mixture to obtain the composite sterilization algicide. Thecomposite sterilization algicide has obvious sterilization and algae removal effects on bacteria, algae and the like in a water system.

Description

technical field [0001] The invention belongs to the technical field of production and application of water treatment agents, and in particular relates to a slow-release composite high-efficiency bactericidal algaecide and a preparation method thereof, which have significant bactericidal and algae-killing effects on bacteria and algae in water systems. Background technique [0002] In industrial water and civil water, eutrophication has become one of the main factors restricting water utilization. The excessive reproduction of bacteria and algae seriously affects the function of the water body. On the one hand, it will pollute the water pipeline, block the filter, and cause water supply accidents; on the other hand, it will cause the water body to stink and affect the landscape. In industry, it will cause biological slime to block heat exchange equipment, corrode metals, and affect the safe production of factories. Therefore, the control of bacteria and algae becomes the mai...
