Abstract
The invention discloses an inorganic bromine disinfectant. The inorganic bromine disinfectant contains following raw materials in parts by weight: 1-30 parts of an effective bromine source, 1-25 parts of an effective bromine carrier, 0.5-10 parts of an effective bromine passivant and 40-97.5 parts of water. The inorganic bromine disinfectant is more environment-friendly than a chlorine preparation and is green and safe; the efficiency of killing blue-green algae by the inorganic bromine disinfectant is better than that of the chlorine preparation; the inorganic bromine disinfectant disclosed by the invention is better than a traditional algaecide in the aspect of damaging a water body system.
Description
Technical field
The present invention relates to sterilization field, be specifically related to a kind of inorganic bromine disinfectant and its preparation method and application.
Background technology
Along with the growth at aqueous systems age, the eutrophication of aqueous systems will become more and more serious problem.The a lot of aqueous systems of China is all faced with such challenge now, Taihu Lake, how Poyang Lake and have throughout the year the Dian Chi of blue-green algae problem to be all faced with such problem, be effectively controlled to the problem for more and more scientists' researchs to algae in the situation that not affecting aqueous systems.China is existing, and what the blue-green algae in Drinking Water water source was killed to use is clorox, but chlorinated product is more and more valued by the people the impact of environment and health.
Summary of the invention
Goal of the invention: first technical problem to be solved of invention has been to provide a kind of inorganic bromine disinfectant.Second technical problem to be solved of invention has been to provide the preparation method of above-mentioned inorganic bromine disinfectant.The 3rd technical problem to be solved by this invention has been to provide the application of above-mentioned inorganic bromine disinfectant.The present invention relates to a kind of inorganic bromine class disinfectant that can be used for aqueous systems blue algae killing, utilize the alternative inorganic chlorine preparation of disinfectant of inorganic bromine class to kill blue-green algae.Through evidence, inorganic bromine class disinfectant involved in the present invention is better than inorganic chlorine preparation 20% to the killing effect of algae, and environmental protection.
Technical scheme: for achieving the above object, the present invention is achieved through the following technical solutions: a kind of inorganic bromine disinfectant, comprises following raw material composition according to parts by weight: effectively bromine bromine source 1-30 part, effective bromine carrier 1-25 part, effective bromine passivator 0.5-10 part, water 40-97.5 part.
Wherein, above-mentioned effective bromine bromine source is simple substance bromine, liquid chlorine, sodium bromide, potassium bromide, calcium bromide, one or several compositions in magnesium bromide.
Wherein, the carrier of above-mentioned effective bromine is urea and sodium hydroxide.
Wherein, above-mentioned effective bromine passivator refers to by sodium phosphate, sodium dihydrogen phosphate, one or more compositions in sodium hydrogen phosphate.
The preparation method of above-mentioned inorganic bromine disinfectant, comprises the following steps: first effective bromine carrier is dissolved in water, then in 0-100 DEG C, adds effective bromine bromine source, stirring and dissolving, then add effective bromine passivator in room temperature, after fully dissolving, stir 30 minutes.
Above-mentioned inorganic bromine disinfectant is being killed the application of preparing aspect blue algae killing disinfectant.
Beneficial effect: compared with prior art, advantage of the present invention is as follows: the disinfectant of inorganic bromine class of the present invention is more better than chlorinated product, green safety in environmental protection; The efficiency of the disinfectant of inorganic bromine class on blue algae killing is better than chlorinated product; The disinfectant of inorganic bromine class of the present invention on the destruction of aqueous systems than good many of traditional algicide.
