2. The effective concentration of bromine biocides is far lower than that of chlorine biocides
[0008] Even so, chlorine-based biocides are still widely used because of their economy and good effect at low pH values, while bromine-based biocides are restricted due to their high price.

example 1

[0030] Prepare 1 ton of the medicament of the present invention according to the ratio of sodium hypochlorite: sodium bromide: dimethyl hydantoin: sulfamic acid = 65: 20: 10: 5. First mix 50kg of sulfamic acid and 200kg of sodium bromide in a solid mixer for 20 minutes before pouring out for later use, then mix 650kg of sodium hypochlorite and 20kg of dimethylhydantoin in a solid mixer for 30 minutes, and finally add the pre-mixed The mixture of sodium bromide and sulfamic acid was stirred for another 30 minutes, then weighed and packaged for sealed storage.

Embodiment 2

[0032] In the circulating water field of a ketone-benzene unit in an oil refinery, Euchlorozine was used as an oxidizing fungicide in the past, and dodecyl dimethyl benzyl ammonium chloride (1227) was used as a non-oxidizing fungicide for sterilization. Bacteria control in the system not only has large ups and downs, but the bacteria recover quickly after sterilization, resulting in a low compliance rate, and the bactericidal effect gradually decreases, resulting in drug resistance. In order to control bacteria, on the one hand, increase the concentration of betachlorine, and on the other hand, shorten the dosing The cycle has brought negative effects to the system, and the corrosion rate has increased significantly, resulting in a vicious circle.

Embodiment 3

[0043] In a swimming pool with a water storage capacity of 1,000 tons, chlorine products such as sodium hypochlorite were used for sterilization and disinfection. It is difficult to ensure that the bacteria meet the standard with low doses. Increase the dosage, and the smell of chlorine in the water is too strong, which affects the flow of passengers. Bromclocarb was used instead, and 5kg of compound three agents were added every day for two weeks, the qualified rate of bacteria index reached 100%, and the chlorine smell was greatly reduced.

Abstract

A bromine-contained biocide used for public place and sewage treatment contains chlorine supplying agnet, bromide and stabilizer of bromine and chlorine in ratio of (50-85):(10-45):(5-15). Its advantages are long acting period, good corrosion inhibiting effect.

Description

technical field [0001] The present invention is an oxidized bromine-containing composite biocide, broclocarb, which is applied in the field of industrial water and public places, such as swimming pools, hotel toilets, and the field of sewage reuse widely developed at present. Background technique [0002] In the field of oxidizing biocides, chlorine and bromine biocides are dissolved in water, and the biocidal mechanism is similar. The bactericidal effect of chlorine and bromine in water is realized by the hypochlorous acid (HCLO) and hypobromous acid (HBrO) generated by their hydrolysis reaction in water. The hydrolyzed hypohalous acid has considerable activity and is easy to combine with the protoplasm in the microorganisms in the water, and then form a stable nitrogen-halogen bond with the protein protein, thereby interfering with the metabolic process of the microorganisms and causing the death of the microorganisms by poisoning. But the bactericidal effects of the two ...
