Description

Technical Field

[0001] The invention belongs to the technical field of animal husbandry, and particularly relates to a method for preparing a duck farm deodorizing agent. Background Art

[0002] The ammonia concentration in the duck house is too high. This is produced when nitrogen-containing organic matter in the feces is fermented and decomposed by bacteria. It is highly irritating, especially to the mucous membranes, and often causes congestion and edema of the duck's conjunctiva and upper respiratory tract mucosa. It is not only easy to induce respiratory diseases, but also has adverse effects on the growth and development of ducks and egg production. Especially in winter, when ventilation and insulation conflict, many farmers ignore ventilation in the duck house in order to keep warm, resulting in excessively high ammonia concentrations in the duck house; in high temperature seasons, ammonia is also prone to increase, which not only induces various diseases, but also brings difficulties to the treatment of other diseases. Therefore, it is important to eliminate ammonia in the duck house and keep the air fresh for the health of ducks. At the same time, a large amount of odor substances are produced, and the fishy smell of duck manure is more likely to cause complaints from the surrounding people. How to eliminate the harmful gases that have been produced has become a very headache for many duck farmers. At present, there are many methods for deodorizing duck farms on the market, such as feed improvement, activated carbon adsorption, etc., but the effect is not as significant as the current new duck farm deodorizer. Our new duck farm deodorizer uses a physical contact deodorization method to quickly capture, absorb and decompose odor molecules such as ammonia, hydrogen sulfide, and methyl mercaptan in odorous gases, degrading them into water and carbon dioxide, thereby achieving the purpose of long-term deodorization. The use of this commonly used duck farm deodorizer can greatly improve the economic benefits of duck farming and effectively solve the problems caused by odor. Duck farms can bring huge economic benefits. Therefore, the development of scientific and reasonable breeding industry (duck farms) can truly realize ecological breeding as long as it follows the requirements of environmental protection and ecological principles, adheres to scientific planning, reasonable layout, protects in development, develops in protection, and protects while developing, so that duck farming and agricultural production form a virtuous ecological cycle, and achieve the synchronous development of economic development and ecological environment protection. Summary of the invention

[0003] In order to solve the above problems, the present invention discloses a method for preparing a duck farm deodorizing agent.

[0004] To achieve the above object, the technical solution of the present invention is as follows: The present invention provides a method for preparing a duck farm deodorizing agent, comprising the following steps: S01, add sodium bicarbonate solution to EDTA chelated zinc, heat to 50-80°C, stir for 1h-3h, and obtain solution A; S02, grind ferrous sulfate, sodium carbonate, boric acid and magnesium sulfate into 500-700 mesh powders respectively, add surfactant after mixing, continue grinding for 5h-7h, then add deionized water, stir for 2h-4h and filter, and retain the solution as solution B; S03. After stirring and mixing solution A and solution B, add malic acid, plant extract and water, stir at a temperature of 65-85° C. for 2 h-4 h, and obtain a duck farm deodorant after cooling.

[0005] Furthermore, in step S01, the mass ratio of sodium bicarbonate to EDTA chelated zinc in the sodium bicarbonate solution is 99-95:1-5.

[0006] Furthermore, the concentration of the sodium bicarbonate solution is 1000-5000 mg / L.

[0007] Furthermore, in step S02, the mass ratio of ferrous sulfate, sodium carbonate, boric acid, magnesium sulfate, surfactant and water is 1-5:1-5:1-5:1-5:1-10:95-70.

[0008] Furthermore, in step S02, the stirring temperature is 50-70°C.

[0009] Furthermore, in step S02, the surfactant is one or more of cocamidopropyl betaine and coconut oil fatty acid diethanolamide.

[0010] Furthermore, in step S03, the mass ratio of malic acid, plant extract and water is: 1-5:0.1-0.5; the volume ratio of solution A to solution B is 1-5:9-5.

[0011] Furthermore, in step S03, the mass ratio of malic acid to solution A is 1-5:99-95.

[0012] Furthermore, the plant extract is mint essence.

[0013] The beneficial effects of the present invention are: (1) The present invention uses EDTA chelated zinc as a raw material to prepare a duck farm deodorant with fast reactivity, enhanced activity, and a large specific surface area. It can induce the generation of hydroxyl free radicals and active oxygen ions ROS with reducing effects, forming a good deodorizing activity. The zinc atoms in the deodorant can not only react with hydrogen sulfide and ammonia in the odor, but also react with -NH, -COOH, -SH and the like in bacteria, thereby destroying the structural composition of the cells, preventing their reproduction, and achieving the effect of killing bacteria and molds; the duck farm deodorant exhibits excellent decomposition activity, can quickly decompose hydrogen sulfide, ammonia, methyl mercaptan and other odor molecules in duck manure in the duck farm to react and generate odor-free molecules, achieve a fast and efficient deodorizing effect with the assistance of malic acid, and achieve the effect of quickly repelling flies and mosquitoes with the assistance of mint essence.

[0014] (2) The surfactant used in the present invention can improve the stability of the duck farm deodorizer, and can make the duck farm deodorizer non-stratified, non-agglomerated, non-precipitated, and transparent in color, while ensuring that the deodorizing properties of the duck farm deodorizer are long-lasting and stable.

[0015] (3) The deodorant for duck farms of the present invention is practically non-toxic, has a long-lasting deodorizing effect, and is non-irritating to mucous membranes. It can quickly decompose the toxic and harmful gases produced by duck manure in the duck farm, and can refresh and purify the air in the duck farm if used for a long time. DETAILED DESCRIPTION

The olfactory sensory evaluation results of the duck farm deodorizer prepared without changing other components and processes are shown in Table 3, and the results of the deodorization test are shown in Table 4. Test Example 1

[0032] The olfactory test was used to evaluate the deodorizing effect. The olfactory test method is a method for evaluating the odor intensity and suitability based on human sense of smell, and determining the characteristic parameters of malodor (smell threshold or concentration, sensory intensity, etc.). A 6-person olfactory test team (18-45 years old, non-smokers, normal sense of smell) was set up. The effect evaluation index of duck manure after being treated with the duck farm deodorant prepared in Examples 1-5 was divided into five indicators: significant 4 points, good 3 points, general 2 points, poor 1 point, and invalid 0 points. There were five groups in total, and the average score of each group was statistically averaged, that is, the best was 4 points and the worst was 1 point. After the test group was evaluated, the evaluation index of more than 4 people could be used as the test conclusion, otherwise it would be re-evaluated. The specific results are shown in Table 1 below.

[0033] Table 1 Olfactory sensory evaluation results of the simulated duck farm deodorization test

[0034] It can be seen from the data in Table 1 that the duck farm deodorizing agents prepared in Examples 1-4 can effectively deodorize, among which the duck farm deodorizing agent prepared in Example 5 can more effectively deodorize duck manure in the duck farm and has the best effect. Test Example 2

[0035] Select 5 enclosed spaces, each of which is 1 m 3 , put a bucket of duck manure from a duck farm that has produced a foul odor in each space, each bucket of duck manure weighs 5 kg, the indoor temperature is controlled at 30-35°C, select 5 spaces as the deodorizing test of the duck farm deodorizer prepared in Examples 1-5, and spray the duck farm deodorizer directly on the duck farm duck manure; after the duck farm deodorizer is sprayed, the ammonia, hydrogen sulfide concentration, methyl mercaptan concentration, and methyl sulfide concentration in the room are detected every 5 days, and the removal rates of ammonia concentration, hydrogen sulfide concentration, and odor concentration are calculated respectively with the blank room as the control, and the monitoring time is 30 days. The specific results are shown in Table 2 below. The detection methods used include GB / T14678-1993 Air Quality-Determination of Hydrogen Sulfide, Methyl Mercaptan, and Methyl Sulfide-Gas Chromatography, GB / T14675-199 Air Quality-Determination of Malodor-Three-Point Comparison Stink Bag Method.

[0036] Table 2 Results of the deodorant test in a simulated duck farm

[0037] As can be seen from the data in Table 2, the duck farm deodorizers prepared in Examples 1-4 have certain deodorizing effects, and the duck farm deodorizer in Example 5 has the best effect, with the average removal rates of ammonia, hydrogen sulfide, methyl mercaptan, and methyl sulfide being 96.63%, 96.7%, 95.45%, and 95.76% for 30 days, respectively. The duck farm deodorizer of the present invention has excellent deodorizing effects, such as removing toxic and harmful gases such as ammonia and hydrogen sulfide. And the deodorizing duration can reach at least 30 days. Test Example 3

[0038] The olfactory test is also used to evaluate the deodorization effect. The olfactory test method is a method to evaluate the intensity and suitability of odors based on human sense of smell, and to determine the characteristic parameters of malodors (smell threshold or concentration, sensory intensity, etc.). A 6-person olfactory test team (18-45 years old, non-smokers, normal sense of smell) was established. The effect evaluation index of duck manure after being treated with the duck farm deodorant prepared in comparative examples 1-5 was divided into five indicators: significant 4 points, good 3 points, general 2 points, poor 1 point, and ineffective 0 points. There were five groups in total, and the average score of each group was calculated, that is, the best was 4 points and the worst was 1 point. After the test group was evaluated, the evaluation indicators of more than 4 people could be used as the test conclusion, otherwise it would be re-evaluated. The specific results are shown in Table 1 below.

[0039] Table 3 Olfactory sensory evaluation results of the simulated duck farm deodorization test

[0040] It can be seen from the data in Table 3 that the duck farm deodorizing agents prepared in Comparative Examples 1 to 5 have poor deodorizing effects, which is mainly due to the fact that less corresponding components are added during the preparation process, resulting in the poorest deodorizing effect of the duck farm deodorizing agents on duck manure in duck farms. Test Example 4

[0041] Similarly, five enclosed spaces are selected, each of which is 1 m 3 , put a bucket of duck manure from a duck farm that has produced a foul odor in each space, each bucket of duck manure weighs 5 kg, the indoor temperature is controlled at 30-35°C, select 5 spaces as the deodorization test of the duck farm deodorant prepared in Comparative Examples 1-5, and spray the duck farm deodorant directly on the duck farm duck manure; after the duck farm deodorant is sprayed, the ammonia, hydrogen sulfide concentration, methyl mercaptan concentration, and methyl sulfide concentration in the room are tested every 5 days, and the removal rates of ammonia concentration, hydrogen sulfide concentration, and odor concentration are calculated respectively with the blank room as the control, and the monitoring time is 30 days. The specific results are shown in Table 2 below. The detection methods used include GB / T14678-1993 Air Quality-Determination of Hydrogen Sulfide, Methyl Mercaptan, and Methyl Sulfide-Gas Chromatography, GB / T14675-199 Air Quality-Determination of Malodor-Three-Point Comparison Stink Bag Method.

[0042] Table 4 Results of the deodorant test in a simulated duck farm

[0043] From the data in Table 4, it can be seen that the deodorizing effects of the duck farm deodorizers prepared in Comparative Examples 1 to 5, such as removing toxic and harmful gases such as ammonia and hydrogen sulfide, are not ideal. Compared with Table 2, the overall deodorizing effect is quite different.
