Description

A kind of micro-ecological preparation spraying method for eliminating stench in livestock and poultry farms

technical field

The invention relates to a method for micro-ecological deodorization and air purification, in particular to a method for spraying micro-ecological preparations to remove stench from livestock and poultry farms.

Background technique

Odor is a kind of sensory pollution, and the main components of odorous gases that are harmful to human health are ammonia and hydrogen sulfide. Many countries classify odor pollution as air pollution and separately list it as a public hazard, and carry out special legislation to implement prevention and control. Due to the limitation of excrement and other equipment, traditional poultry and livestock farms are often subject to serious odor pollution, and an effective and harmless air purification method is urgently needed. Many physical or chemical air purification methods just cover up the sense of smell, or cause secondary pollution or high cost, while using microecological preparations to create a self-purifying air microecological system with low cost and no pollution is suitable for large-scale long-term use in farms. Has become a popular new deodorization method.

Contents of the invention

The object of the present invention is to provide a method for eliminating the stench of livestock and poultry farms by spraying micro-ecological preparations with quick effect, wide area, low cost and no pollution.

The purpose of the present invention is achieved through the following technical solutions:

A method for removing the stench of livestock and poultry farms by spraying micro-ecological preparations: introducing the micro-ecological preparations into a pipeline with a nozzle, and using the nozzle to spray the micro-ecological preparations from above the odor source of the livestock and poultry farms into a fine mist, and the micro-ecological preparations The fine mist fully contacts and absorbs the malodorous gas during the landing process to achieve rapid deodorization; spray at least twice a day, each time lasts 10 minutes, and the interval between the two times is at least 6 hours. The total daily dosage for the first 3 days is 0.5-1.5 kg per Cubic meters, and then maintain the daily dosage of 0.2 to 0.5 kg per cubic meter.

In parts by weight, the formula of the probiotics consists of the following components: 20-60 parts of water, 10-20 parts of bacillus, 10-20 parts of lactic acid bacteria, 10-20 parts of nitrifying bacteria and 10-20 parts of photosynthetic bacteria. 20 servings.

In order to further realize the object of the present invention, the bacillus is bacillus subtilis and bacillus licheniformis, wherein contains bacillus subtilis 40～60% (weight), bacillus licheniformis 40～60% (weight).

The lactic acid bacteria is Lactobacillus acidophilus.

The nitrifying bacteria are ammonia oxidizing bacteria and nitrite oxidizing bacteria, wherein 50-80% (weight) of ammonia oxidizing bacteria and 20-50% (weight) of nitrite oxidizing bacteria.

The photosynthetic bacterium is Rhodospirillum.

The malodorous gas _NH3 in livestock and poultry farms is less than the specific gravity of the air, and it will rise continuously from the source of the odor after it is produced. The method of the present invention is to spray the micro-ecological agent in the form of fine mist from above to absorb and degrade the odor and harmful gases in the air. To achieve the purpose of deodorization and disinfection.

Compared with the prior art, the present invention has the following advantages and beneficial effects:

(1) The area is wide. The present invention adds probiotics to the transfusion tank, sprays the fine mist of the preparation from the top of the odor source through the delivery pipe and the nozzle, and waits for it to slowly fall in the air, and the living microorganisms therein will quickly absorb the malodorous gas (such as NH3, _H2 S, etc.), use the SHWESER121 hollow nozzle, the aperture is greater than 0.3mm, and the maximum atomization angle is 120 degrees, which can cover a large area, further improve the contact efficiency of microorganisms and air, and quickly deodorize.

(2) quick effect. The method for spraying and deodorizing the probiotic preparation of the present invention can obviously deodorize within one day, and the ammonia content is degraded by 60% to 70% within one day, and completely degraded within three days.

(3) Environmental protection. The microorganisms in the preparation have strong degradability at room temperature, and will die out after the pollutants are decomposed, decomposing into carbon dioxide, water and non-toxic cell residues, which can be safely discharged into the soil, with a high degree of dispersion, and are non-toxic to humans and animals Harmless, will not cause secondary pollution.

Detailed ways

The present invention will be further described below in conjunction with the examples. It should be noted that these examples do not constitute a limitation to the protection scope of the present invention.

As shown in FIG. 1 , a device for spraying probiotics to remove odor from livestock and poultry farms includes an infusion tank 1 , a delivery pump 2 , a delivery pipeline 3 and a nozzle 4 . The infusion tank 1 is connected to the delivery pump 2, the delivery pipeline 3 is connected to the delivery pump 2, and the nozzle 4 is arranged on the delivery pipeline 3, which is located at about 2 meters above the odor source. When in use, add the micro-ecological preparation to the infusion tank 1, turn on the delivery pump 2, and turn on the nozzle 4 for about 10 minutes. The fine mist of the micro-ecological preparation fully contacts and absorbs the malodorous gas during the falling process, and the odor is obviously weakened after two hours. If the smell is particularly strong, you can start spraying again after an interval of two hours, and then repeat the cycle several times after an interval of two hours. Spraying needs to use fresh micro-ecological preparations, the amount of use can be added or subtracted according to the actual situation, and it can be used up once one sample is added, and it cannot be stored in the pipeline for a long time. Generally, the effect is obvious within two hours, and the odor will disappear after continuous use for a week, which is suitable for long-term use in farms.
