Description
Technical Field
The invention relates to the technical field of disinfectants, in particular to a chlorine dioxide disinfectant.
Background
Chlorine dioxide is a new generation of safe, efficient and broad-spectrum sterilizing, fresh-keeping and deodorizing agent internationally acknowledged at present, is the most ideal substitute of a chlorine preparation, and has been widely applied in developed countries.
Chlorine dioxide has been approved and recommended in the united states, canada, japan, western europe, etc. for disinfection, deodorization, mold prevention, preservation of food, disinfection of food processing industry, pharmaceutical industry, hospitals, public environments, etc., and the like. The World Health Organization (WHO) has also listed chlorine dioxide as A1Safe and efficient disinfectant. In order to control the generation of 'three-causing substances' (teratogenicity, carcinogenesis and mutation) in drinking water, chlorine dioxide is widely popularized and applied to replace chlorine to disinfect drinking water in developed countries in Europe and America. In recent years, China also pays attention to popularization and application of chlorine dioxide, products are continuously appeared, and the national ministry of health also approves that chlorine dioxide is used as a disinfectant and a novel food additive.
Among the diseases causing death of aquaculture animals, more than 70% are infectious diseases caused by infectious pathogens such as viruses, bacteria, fungi and unicellular algae. At present, in the aquaculture process, the most application is to perform chlorination disinfection by using a chlorine preparation which has strong bactericidal power and is convenient to use so as to kill various harmful microorganisms and prevent and treat the occurrence and the prevalence of various infectious diseases. Such as chlorine, bleaching powder, strong chlorine, dichloro or trichloro-iso-uric acid, bromochlorohydantoin, etc., however, as the water quality of the aquaculture water is gradually worsened and the awareness of pollution-free safety, sanitation and health of people is enhanced, the side reaction of chlorination and the limitation thereof are gradually revealed. Therefore, the superiority of chlorine dioxide as a substitute of chlorine preparations is increasingly highlighted.
Disclosure of Invention
The invention provides stable chlorine dioxide to replace the existing chlorine preparation product.
The technical scheme of the invention is as follows:
a chlorine dioxide disinfectant is characterized in that:
the component A is as follows: sodium chlorite: 180-235 parts of anhydrous sodium sulfate or zeolite powder: 165-220 parts;
and (B) component: citric acid or sodium hydrogen sulfate: 300-500 parts;
mixing sodium chlorite in the component A with anhydrous sodium sulfate or zeolite powder, and independently assembling; the component B is independently assembled; A. the component B and the component A are separately placed, when in use, the component A and the component B are respectively dissolved in a container filled with clear water, the mixture is stirred to be completely dissolved, and then the solution of the component A is slowly poured into the solution of the component B under stirring, the solution is yellow, and at the moment, chlorine dioxide is generated.
Because the raw material sodium chlorite of theproduct is dangerous, A, B two components should not be put together and should be placed separately during preparation, and the obtained chlorine dioxide has the effect of disinfection and sterilization after being sprinkled into water.
Characteristics of chlorine dioxide disinfectant raw materials
Sodium chlorite: sodium chlorite is a white crystal, and often contains chlorine dioxide, which is yellowish green. The product has two forms of anhydrous substance and trihydrate, and has a transfer temperature of 38 deg.C, slight hygroscopicity, and stability at room temperature. Industrial sodium chlorite contains water and other impurities, and when heated to 130-140 ℃, it decomposes to release oxygen even at lower temperatures. Dissolved in water and alcohol, and especially has high solubility in water. An alkaline aqueous solution of sodium chlorite is stable to light; the acidic aqueous solution is liable to release chlorine dioxide gas and to cause explosive decomposition. Sodium chlorite is a highly effective oxidant and excellent bleaching agent. The available chlorine content of pure sodium chlorite is 157%, and the purity of industrial product is above 80% and also can be up to 130%. The bleaching powder is 7 times that of bleaching powder and 2 times that of bleaching powder.
Since sodium chlorite is alkaline and is adjusted to be acidic at the time of use, an acidifying agent, also referred to as an activator, must be added. Citric acid or sodium bisulfate is used as an activator in the present aspect. The acid activation can cause a large amount of chlorine dioxide to escape, the bleaching effect is intensified, and the disinfection effect is better.
The reaction principle is as follows:
chlorine dioxide belongs to an oxidation disinfectant and is applied to aquaculture. The chlorine dioxide is considered as a A1-grade new-generation chemical disinfectant by international organization, and can effectively prevent and treat diseases such as gill rot, red skin, enteritis, fin rot, scale rot, tail rot, bleeding, shrimp and crab rotten limbs, rotten shell, black gill, trembling and the like of fishes when the chlorine dioxide is applied to aquaculture.
Firstly, the disinfection effect is good. Has strong oxidizability, and can kill various bacteria, viruses, moulds, fungi, algae, bacterial spores and the like in a small dosage. The low concentration has strong diffusion speed and permeability in water, the sterilization rate is 90 percent after 5 minutes of action of 5 mg/L chlorine gas, and 100 percent of various microorganisms can be killed by only 30 seconds of action of 2 mg/L chlorine dioxide.
Secondly, the disinfection effect is not influenced by factors such as PH value and the like. At pH 6-10, the disinfecting effect of the chlorine preparation decreases with increasing pH, and chlorine dioxide is stable. Under the condition of pH8.6, chlorine dioxide with the concentration of 0.5 mg/L and chlorine react for 12 hours, the sterilizing efficiency of chlorine dioxide is kept above 99%, while the chlorine can only reach 75%, and the sterilizing efficiency can only reach above 90% when the concentration is increased to 1 mg/L. In addition, since chlorine dioxide does not react with ammonia and amine, the sterilizing effect is not affected by the concentrations of ammonia and amine in the water.
And thirdly, the generation of THMS harmful substances can be avoided. The THMS compound as a by-product is generated in the chlorination disinfection process, the problem of carcinogenesis exists, and the chlorine dioxide disinfection cannot occur. The method comprises the following steps: the content of THMS in the peripheral water sterilized by chlorine preparation in the same water source is 0.5-124.6 microgram/liter, and no THMS compound is detected by using chlorine dioxide for sterilization.
Fourthly, the harmful substances in the water body can be decomposed. The chlorine dioxide can remove excessive inorganic pollutants such as Fe2+, Mn2+, S2+, CN<-> and organic pollutants such as phenols and humus in the water body. Chlorine dioxide oxidizes hydrogen sulfide to ferric sulfate at a pH of 5-9. Has strong effect in removing musty and fishy smell, and can improve water quality
