With the arrival of summer, the stench of the farm is getting heavier, making everyone feel very uncomfortable. In fact, many farms are usually like this. It’s just that in the high temperature in summer, some volatile substances volatilize faster and the concentration of odorous substances formed is higher, so it is more intolerable.
With the expansion and intensification of animal husbandry production, a large number of livestock and poultry will be produced at the same time, and a large number of odors will also be discharged. These odors not only endanger the health of livestock and poultry, reduce their resistance, hinder production performance, but also It will affect the health of the breeders, and it will also pollute the environmental pig farms. So how can the farm get rid of this stench? Let’s take a look together.
1. The main hazards of farm odor:
Malodorous substances can cause different degrees of toxicity to the respiratory, digestive, cardiovascular, endocrine and nervous systems of animals and breeders.
a) Breeding animals: With the increasing degree of intensive breeding and the increasing density of breeding, the “health-care drugs” for the respiratory tract and digestive tract of farmed animals have risen sharply. In the “health care plan” recommended by many veterinary drug manufacturers, the types and doses of antibiotics are constantly increasing. This is a huge food safety hazard or hazard for both raising animals and people consuming the animal products. The cost of farm “health programmes” is also increasing.
b) Breeding staff: For the operators in the animal house, the first is to endanger the health of the breeding staff, and the harmful gases have the greatest impact on the respiratory tract and nervous system of the staff; Hurry up and leave this environment, without the intention to carefully operate and observe. Therefore, many feeding and management work cannot be in place.
c) Surroundings: Many farms can feel their presence from far away because the smell is too great. It has a great impact on many surrounding environments, and it is also the most complained aspect of the farm.
Second, the current main deodorization methods:
a) Ventilation of the livestock house: When some technical means have not been developed in the past, our frequent suggestion is to keep the livestock house dry and keep the livestock house well ventilated. In fact, this is mainly to use natural, artificial assistance and other means to “dilute the odor” to spread it into a larger environment and reduce the concentration of odor in the local area. But winter insulation and so on become a problem.
b) Deodorization of airtight animal houses: use positive pressure and negative pressure fans, and adopt forced ventilation to remove stench in the animal house. With this method, most of the harmful gases in the livestock house are diluted, but the foul smell is often permeated around the farm. This method is actually a simple method of “diluting the concentration of harmful gases”, rather than fundamentally solving the problem of odor.
c) Rinse method: Rinse with a lot of water, which is actually a kind of “dilution” method. The effect, each farm has its own conclusion. The key is that the discharge of flushing wastewater becomes a larger pollutant.
d) Deodorization equipment: Some equipments using the principle of ozone and OH- ion generation have a good decomposition effect on various odor substances. However, in the use of farms, equipment costs and operating costs are the biggest obstacles. Some water shower + chemical deodorant facilities also have cost barriers.
3. Recommended deodorization scheme for farms
Use deodorant pads
The wet curtain adopts new materials and space cross-linking technology, which has high absorption, high water resistance, mildew resistance, corrosion resistance and long service life.
“Livestock and poultry house purification and deodorization system” is an air purification device specially developed by Wusen Agriculture and Animal Husbandry Environmental Protection for intensive animal husbandry. Provide tailor-made services for farms in different regions. The deodorization system of pig farms consists of multiple devices such as deodorization filter blocks, circulating spray, circulating water treatment, and intelligent control. The removal rate of ammonia gas reaches 70-95%. , The removal rate of odor such as hydrogen sulfide can reach 40-75%, and the dust removal rate can reach 45-80%. The deodorizing equipment is modular in design and can be quickly installed on site.
