Description
Technical Field
The invention relates to a disinfection deodorant, in particular to a disinfection deodorant for eliminating stink and pathogenic microorganisms in livestock and poultry farms and a preparation method thereof, belonging to the technical field of disinfection and deodorization.
Background
Malodorous gases (including methane, ammonia gas, hydrogen sulfide, mercaptan, amines and the like) in livestock and poultry farms are mainly generated by decomposing animal excreta by microorganisms in poultry houses. The malodorous gas is toxic and harmful, and the excessive ammonia gas can cause the animals to become restless, reduce appetite, lose weight, even cause bleeding of respiratory mucosa, cause respiratory diseases and the like. The mercaptan malodor can cause nervous disorder, headache, nausea, vomiting and even paralysis and death of livestock and poultry. The emission standards of 9 kinds of malodorous pollutants are strictly defined in the emission standards of malodorous pollutants (GB-14554-93) issued by the ministry of environmental protection as early as 1993. In addition, according to the reports of Chinese academy of agricultural sciences, the types of pathogenic bacteria in livestock and poultry farms are as high as 18, and various pathogenic bacteria can cause animals to generate various diseases, for example, pasteurella multocida can cause livestock and poultry to generate hemorrhagic septicemia and the like. The foul gas in the livestock and poultry farm is diffused, various harmful germs are bred, the normal growth of the livestock and poultry is seriously harmed, the economic benefit of the livestock and poultry is influenced, and meanwhile, the health of breeding personnel and surrounding residents is harmed.
Aiming at the treatment of malodorous gas in livestock and poultry farms, the current main methods comprise an absorption method, an adsorption method and a biological method. The absorption method is to absorb malodorous gas by water, acid (alkali) liquid and the like, and the absorption method is to absorb malodorous gas by using active carbon, zeolite and the like as materials, but the malodorous gas can be effectively controlled by the absorption method and the adsorption method, but the malodorous gas can not be fundamentally eliminated, and the absorption method also has the defects of large consumption of absorption liquid or adsorbent, difficult advanced treatment of generated waste liquid and solid waste and the like. The biological method applies microorganisms to catalyze and decompose malodorous substances, is an efficient and green treatment method, but has the defects of complicated growth control conditions of accessed microorganisms and high input cost, so that the method is limited. In addition, the elimination of pathogenic microorganisms in livestock and poultry breeding mainly depends on spraying disinfectants, which mainly comprise aldehydes, alcohols, heterocycles, phenols, chlorines, iodines, peroxides and the like.
It is worth noting that there is currently very little research on the ability to treat malodorous gases and pathogenic microorganisms simultaneously. It is reported that the peroxide is concerned about the characteristics of high sterilization efficiency, no pollution residue and the like, and meanwhile, the peroxide has strong oxidative decomposition effect on malodorous gas. However, a single inorganic peroxide cannot effectively remove various complicated malodorous gases. For example, chinese patent publication No. CN 104784730A discloses an enzyme deodorant, which mainly comprises calcium peroxide, sodium percarbonate, and horseradish peroxidase, and maintains the removal efficiency of ammonia gas, hydrogen sulfide, and malodor intensity at about 50%, and the efficiency is low. Aiming at the problems, the invention provides a disinfection deodorant which can efficiently remove complex malodorous gas and kill pathogenic microorganisms, is safe and reliable, and meets the requirements of safety, greenness and no pollution.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a disinfection deodorant which can simultaneously eliminate complex malodorous gas efficiently and safely and kill pathogenic microorganisms.
Another object of the present invention is to provide a method for producing a disinfectant deodorant.
The main components of the disinfection deodorant provided by the invention are sodium percarbonate, calcium peroxide, sodium persulfate, peroxybenzoic acid, malic acid, hydroxypropyl methylcellulose and sodium hexametaphosphate.
The main components comprise 400 portions of sodium percarbonate 200-.
Further, the main components comprise 350 parts of sodium percarbonate 280-containing material, 250 parts of calcium peroxide 180-containing material, 80-100 parts of sodium persulfate, 80-100 parts of peroxybenzoic acid, 60-80 parts of malic acid, 20-35 parts of hydroxypropyl methylcellulose and 250 parts of sodium hexametaphosphate 150-containing material.
Furthermore, the main components are prepared from 320 parts of sodium percarbonate, 200 parts of calcium peroxide, 90 parts of sodium persulfate, 89 parts of peroxybenzoic acid, 75 parts of malic acid, 30 parts of hydroxypropyl methylcellulose and 180 parts of sodium hexametaphosphate.
The invention also provides a preparation method of the disinfection deodorant, which comprises the following steps:
(1) weighing sodium percarbonate, calcium peroxide, sodium persulfate and peroxybenzoic acid according to the weight ratio, and crushing and sieving to obtain a component 1;
(2) weighing malic acid, sodium hexametaphosphate and hydroxypropyl methyl cellulose according to the weight ratio, and crushing and sieving to obtain a component 2;
(3) adding the component 2 into the component 1, fully and uniformly mixing, and then adding safe and available auxiliary materials to prepare the composition.
The preparation form of the disinfection deodorant prepared by the preparation method can be as follows: powder, granule, and solution.
The components used in the invention are safe and environment-friendly, have no toxic or side effect on human beings and animals, have no residue, and are repeatedly verified through a large number of animal tests. The disinfection deodorant has the effects of small dosage, long-acting slow release, long-term keeping of fresh air in the environment of livestock and poultry farms and killing of pathogenic microorganisms.
The disinfection deodorant of the invention has the advantages and positive effects that:
(1) hydrogen peroxide is a safe and effective environmental disinfectant raw material recognized in the world at present, and a diluent of the hydrogen peroxide is widely applied to environmental disinfection. The hydrogen peroxide is a strong oxidant, and can form active oxygen (O) and hydroxyl free radical (OH) with strong oxidizing capability besides the self-oxidizing function, and can gradually oxidize complex and various malodorous gases into non-toxic salts, carbon dioxide and water. The microorganism can also be killed by destroying enzyme, protein and DNA in the pathogenic microorganism, thereby achieving the purposes of eliminating malodor and killing pathogenic microorganism.
(2) Sodium percarbonate is called solid hydrogen peroxide, is dissolved in water to release hydrogen peroxide, has the function of hydrogen peroxide disinfection, is convenient to store, transport and use, and converts the hydrogen peroxide into solid sodium percarbonate crystals, and is widely used in the fields of household and industrial washing, bleaching, bactericides and the like. The calcium peroxide is dissolved in dilute acid to generate hydrogen peroxide, and the hydrogen peroxide can be gradually and slowly decomposed in wet air or water, so that active oxygen groups can be released for a long time, and the long-acting sterilization and deodorization effects are achieved. Calcium peroxide is non-toxic and does not pollute the environment, and is widely applied to the field of disinfection.
(3) Sodium persulfate originally used as a digestion substance for testing total nitrogen and total phosphorus in water samples was later found to generate strongly oxidizing sulfate radicals (. SO) under thermal activation and transition metal activation4). Sulfate radicals are similar to hydroxyl radicals, have strong oxidizability, and can destroy most organic pollutant molecules. Relevant researches show that sulfuric acid, free radicals and hydroxyl free radicals are combined for use, and the organic pollutant molecules are strongly and efficiently oxidized and eliminated.
(4) Perbenzoic acid is used as an organic peroxy acid, on one hand, unsaturated olefin substances in malodorous gas can be oxidized into oxygen-containing organic substances, so that active oxygen groups can be conveniently oxidized and destroyed further; on the other hand, the peroxybenzoic acid can be cooperated with malic acid, and not only can regulate and control the decomposition rate of calcium oxide by adjusting and stabilizing the pH value of the disinfection deodorant during the action, but also can cooperate with sodium percarbonate to enable the disinfection deodorant to efficiently and durably disinfect and deodorize to the maximum, and maintain the environment clean.
(5) In the invention, the hydroxypropyl methyl cellulose and the sodium hexametaphosphate can enhance the caking property among the components of the disinfection deodorant and increase the stability among solid mixtures. The sodium hexametaphosphate also helps the components to be uniformly dispersed and distributed, and can effectively prevent light and heat from decomposing and disinfecting the deodorant.
(6) The disinfection deodorant prepared by the invention is prepared by mixing sodium percarbonate, calcium peroxide, sodium persulfate, peroxybenzoic acid, malic acid, hydroxypropyl methylcellulose, sodium hexametaphosphate and the like according to the formula proportion strictly, so as to achieve the optimal disinfection and deodorization effects.
(7) The contents of all components of the product are controlled in a non-toxic and harmless range, and no secondary pollution is generated after the product is used, so that the product is a green and environment-friendly product.

In order to verify the effect of the disinfection deodorant of the invention on removing malodorous gases and pathogenic microorganisms, the following test examples are provided to illustrate the efficacy of the disinfection deodorant of the invention.
Test example 1
1.1 test materials
In order to ensure the scientificity of the test, the disinfectant and deodorant of the present invention used in test example 1 was modified as follows: the components and proportions of examples 1, 2, 3, 4, 5, and 6 were kept constant, but the powders were prepared uniformly for this test.
1.2 test set-up
Several sealed hollow plastic cubes with length, width, height =1m 2m were prepared in the laboratory, each cube being equipped with two spray generators. Each cube was numbered, hollow cubes No. 1-6 as test groups and 0 as control group. Equal amounts of pig faeces were dosed into each cube: 1kg of feces and 1L of urine, and the malodorous environment was left standing for 12 hours. Then, according to the principle of single-factor experimental design, 6 kinds of disinfection deodorant (powder) are respectively obtained according to the component ratios used in examples 1-6, 1g of the 6 kinds of disinfection deodorant (powder) is respectively weighed, and the 6 kinds of disinfection deodorant (powder) are respectively and fully dissolved and then sprayed into plastic cubes with corresponding numerical numbers through a spray generator according to the using method described in examples 1 and 3, and the same amount of tap water is sprayed into a No. 0 closed cube, and the spraying time and the steam outlet rate of each group are kept consistent. Three replicates were set for each group. The test period was 1 week. The experimental design is shown in table 1:
1.3 detection instruments and indexes
And respectively detecting each index of the odor and the number of the pathogenic bacteria by using a portable odor detector and an ATP microbial fluorescence detector. Each indicator of malodor includes ammonia concentration (NH)3) Hydrogen sulfide concentration (H)2S), Total Volatile Organic Compounds (TVOC), and composite malodor intensity value (OU). All indexes are detected after 3 hours (h), 1 day (d), 3 days, 5 days and 7 days after the disinfection and deodorization powder is used, the detection indexes of each plastic cube are repeatedly detected for three times, an average value is obtained, and data obtained by parallel sample detection are integrated to obtain a detection result.
1.4 results and analysis
By calculation, the percentage of ammonia concentration reduction in each group with increasing exposure time after spraying compared to before spraying was obtained, as shown in figure 1.
As can be seen from Table 2 and FIG. 1: the ammonia concentration in control group 0 varied very little before and after spraying except on the day of spraying. The reduction of ammonia concentration on the day of spraying is caused by the fact that ammonia is very soluble in water. After 3 hours of the test group using the disinfection deodorant of the invention, the ammonia concentration is obviously reduced, and the reduction efficiency is between 67.5 percent and 94.4 percent. On the whole, in each test group, the ammonia removal efficiency of the disinfection deodorant is increased and then reduced in the next week, and the ammonia removal efficiency is higher than 60%. The disinfection deodorant can rapidly and obviously reduce the concentration of ammonia gas, and the efficacy can last for one week in the closed environment.
In addition, as is apparent from fig. 1, the test group 5 has the best ammonia removal effect, and the ammonia removal efficiency is over 91.7%, which indicates that the formula of the synthetic raw material in example 5 is the best.
The percentage of hydrogen sulfide concentration reduction in each group with increasing exposure time after spraying compared to before spraying was calculated and is shown in figure 2.
As can be seen from Table 3 and FIG. 2: the hydrogen sulfide concentration in control 0 varied very little before and after spraying. After the disinfectant deodorant disclosed by the invention is used for 3 hours, the concentration of hydrogen sulfide in each test group is remarkably reduced, and the reduction efficiency is between 69.1% and 88.6%. Overall, the efficiency of the disinfectant and deodorant to remove hydrogen sulfide in each test group increased and then decreased in the next week, and the removal efficiency was higher than 59%. The disinfection deodorant of the invention can rapidly and obviously reduce the concentration of hydrogen sulfide, and the efficacy can last for one week in the closed environment.
In addition, as is apparent from fig. 2, the hydrogen sulfide removal effect of test group 5 and test group 6 is optimal, and the removal efficiency is above 87%, which indicates that the synthetic raw material formulations in example 5 and example 6 are both desirable.
By calculation, the percentage of the reduction in TVOC concentration in each group with the increase in the action time after spraying compared to before spraying was obtained, as shown in fig. 3.
As can be seen from Table 4 and FIG. 3: the TVOC concentration in control group 0 was substantially unchanged before and after spraying. After 3 hours of using the disinfection deodorant of the invention, the TVOC concentration in each test group is obviously reduced, and the reduction efficiency is between 57.9 percent and 87.5 percent. Overall, the removal TVOC efficiency of the disinfecting and deodorizing agent in each test group increased and then decreased during the next week, but the removal efficiency was higher than 43%. The disinfection deodorant can rapidly and obviously reduce the TVOC concentration, and the efficacy can last for one week in the closed environment.
In addition, as can be seen from fig. 3, test group 5 has the best effect of removing TVOC, and the removal efficiency is above 84.6%, which indicates that the formulation of the synthetic raw material in example 5 is the best.
The percentage of the decrease in the composite malodor intensity values in each group with the increase in the post-spray exposure time compared to before spraying was obtained by calculation, as shown in fig. 4.
As can be seen from Table 5 and FIG. 4: in the day of spraying, the composite odor intensity in the control group 0 was changed little before and after spraying, and the odor intensity was reduced little in the day of spraying, mainly because the ammonia gas in the malodorous gas is very soluble in water. After the disinfection deodorant disclosed by the invention is used for 3 hours, the stink intensity in each test group is obviously reduced, and the reduction efficiency is 65.2% -98.1%. Overall, the deodorizing efficiency of the disinfecting deodorant in each test group increased and then decreased in the next one week period, but the deodorizing efficiency was higher than 50%. The disinfection deodorant of the invention can rapidly and obviously reduce the strength, and the efficacy can last for one week in the closed environment.
Further, as can be seen from fig. 4, test group 5 showed the best deodorizing effect and the decreasing efficiency of the malodor intensity was 94.2% or more, and test group 6 showed only the second time, and it was preferable to explain the formulation of the synthetic raw material in example 5 or example 6.
The percentage of the decrease in the composite malodor intensity values in each group with the increase in the post-spray exposure time compared to before spraying was obtained by calculation, as shown in fig. 5.
As can be seen from Table 6 and FIG. 5: the number of pathogenic microorganisms in the control group was reduced on the day after spraying, mainly due to the fact that the inner surface of the box was washed by spraying to wash off the pathogenic microorganisms adhered thereto, and after 1 day, the number of pathogenic microorganisms returned to the value before spraying and was always maintained at the value. After the disinfection deodorant disclosed by the invention is used for 3 hours, the number of pathogenic microorganisms in each test group is remarkably reduced, and the reduction efficiency is 65.2% -98.1%. Overall, the efficiency of the disinfection and deodorisation agent in killing pathogenic microorganisms in each test group increased and then decreased in the next week, but the removal efficiency was higher than 50%. The disinfection deodorant has obvious and rapid killing effect on pathogenic microorganisms, and the efficacy can last for one week in the closed environment.
In addition, as can be seen from fig. 5, the test group 5 exhibited the best effect of removing pathogenic microorganisms, and the sterilization efficiency was 89.0% or more, indicating that the formulation of the synthetic raw material in example 5 was the best.
The experimental results can be summarized as follows: the disinfection and deodorization powder has high-efficiency removal effect on malodorous gas and pathogenic microorganisms in a closed environment, can be used for quickly disinfecting and deodorizing, and can maintain the effect for more than one week. The formulation of the synthetic raw materials selected in example 5 was optimized in the disinfection and deodorization powder in accordance with the change of each detection index.
Test example 2
11 months in 2017, the method is carried out in a fattening pig house in a certain Haerbin pig farm, and a test for removing effects of the disinfection deodorant on malodorous gases and pathogenic microorganisms in an actual livestock house is researched. The test is divided into a test group and a control group, the internal structures of the two pigsties are the same, the breeding areas are the same, the number of fattening pigs is the same, the weight of each pig is 80-100 kg, and the type, the weight and the feeding time of the feed are respectively kept consistent during the test period. Before the experiment, the human body can sense the odor in the two piggeries, the odor is very big, the eyes of some pigs can be obviously observed to be red, the pigs are violent and easy to move, and the workers can hardly stand in the piggeries for a long time.
2.1 test method A proper amount of the disinfectant and deodorant of the present invention (prepared by the method of example 5) was dissolved in water at a ratio of 1g:1000mL, atomized by a sprayer, and sprayed all around the pigsty of the test group, and the control group was sprayed with tap water in an amount equivalent to that of the test group without using the product.
2.2 before the test of detection point and detection index, evenly arrange 10 detection position in two pig houses, the detection position of two pig houses is corresponding the same. And (3) detecting the malodor values and the pathogenic microorganisms at each detection position, and comparing and selecting the position with larger malodor value and larger bacterial number as a detection point during the test. During each detection, after the odor value of the point to be detected is relatively stable, 3 values are selected for recording, and the number of the pathogenic bacteria microorganisms in the point is detected for three times. The total test time is one week, and the detection time of each index is 12 at noon: measured in the time of 00-13: 00.
2.3 results and results of the assay and control groups are shown in the following table:
from table 7, it can be seen: the odor intensity and the number of pathogenic microorganisms are reduced within one day after the tap water is sprayed on the control group, because the ammonia gas in the malodorous gas is very soluble in water, and part of pathogenic microorganisms are washed off from the piggery apparatus. However, after one day, the control group had a sudden increase in the intensity of malodor and the number of pathogenic microorganisms. After the sterilizing deodorant is sprayed to a fattening pig house of a test group for 3 hours, the composite odor intensity and the number of pathogenic microorganisms in the pig house are obviously reduced, and the sterilizing deodorant has long-acting effect for more than 5 days, so that the composite odor intensity value of the environment is not rebounded, and the number of pathogenic microorganisms is not increased violently. After spraying the disinfectant deodorant, the worker clearly felt that the foul smell in the pigsty of the test group became weak, and at the same time, the pig was observed to be clearly calm down. The test example shows that the disinfection deodorant of the invention has the function of efficiently removing the malodor and pathogenic microorganism in the actual livestock and poultry breeding environment.
Test example 3
Experiments are carried out on a certain chicken farm in He Bei Handan Quzhou county in 2018 and 3 months, and experiments on the removal effect of the disinfection deodorant of the invention on malodorous gases and pathogenic microorganisms in an actual livestock and poultry house are researched. The test is divided into a test group henhouse and a control group henhouse, the internal structures of the two henhouses are the same, the breeding areas are equal, 14810 henhouses are bred in the control group henhouse, and 14606 henhouses are approximately equal. The weight of each chicken is between 2 and 3 kilograms, and the type, weight and feeding time of the feed are respectively kept consistent during the test period.
3.1 test method A proper amount of the disinfectant and deodorant of the present invention (prepared by the method of example 5) was dissolved in water at a ratio of 1g to 1000mL, atomized by a sprayer, and sprayed all around the test chicken coop, and the control group was sprayed with tap water in an amount equivalent to that of the test group without using the product.
3.2 before the test of the detection points and the detection indexes, 10 detection positions are uniformly arranged in the two henhouses, and the detection positions of the two henhouses are correspondingly the same. And (3) detecting the malodor values and the pathogenic microorganisms at each detection position, and selecting the position with larger malodor value and larger bacterial number as a detection point during the test. During each detection, after the odor value of the point to be detected is relatively stable, 3 values are selected for recording, and the number of the pathogenic bacteria microorganisms in the point is detected for three times. The total test time is one week, and the detection time of each index is 12 at noon: measured in the time of 00-13: 00.
3.3 results and assay test and control test results are shown in the following table:
from table 8, it can be seen: the control group had decreased odor intensity and pathogenic microorganism count within one day after spraying the same amount of water, which was probably caused by the ammonia in the malodorous gas being very soluble in water and some pathogenic microorganisms being washed off from the detection point. However, after one day, the control group had a sudden increase in the intensity of malodor and the number of pathogenic microorganisms. After the disinfection deodorant is sprayed for 3 hours, the odor intensity and the number of pathogenic microorganisms of a test group are obviously reduced, the long-acting effect of the disinfection deodorant reaches more than 5 days, and the composite odor value of the environment and the number of the pathogenic microorganisms are not increased violently. After the disinfectant deodorant is sprayed, workers obviously feel that the odor of the test group is greatly weakened. The test results show that the disinfection deodorant of the invention has high-efficiency removal effect on malodorous gas and pathogenic microorganisms in the actual livestock and poultry environment.
