In the rapid development of the farming industry today, air quality issues are becoming a key challenge that more and more farmers cannot ignore. Chicken coops, pigsties, cowsheds and other enclosed or semi-enclosed places, with the accumulation of manure, it is easy to release a large amount of ammonia, hydrogen sulfide, methyl mercaptan and other irritating gases, which not only seriously affects the health of the workers and the welfare of the animals, but also may trigger complaints from the surrounding residents, and even affects the brand image and long-term development of the farm.
In this context, large deodorizing composting tanks are being adopted by more and more modern farms as an integrated solution for farm waste treatment and deodorization.
Elevated health risks for employees: long-term exposure to high concentrations of ammonia and hydrogen sulfide makes workers susceptible to respiratory irritation, dizziness and other discomforts, and in severe cases may even lead to occupational diseases.
Neighborhood deterioration and frequent complaints: The odor not only affects the farm itself, but may also spread to the surrounding residential areas, bringing public opinion pressure and the risk of environmental penalties.
Damage to brand reputation and loss of cooperation opportunities: In today’s increasingly important green agriculture, farms with substandard environmental protection are often excluded from government support or cooperation with large customers.
Therefore, the introduction of high-efficiency deodorizing composting tanks has become a “necessity” for the development of farms.
In order to solve the above problems, the large deodorizing composting tank independently developed by Bolong Group combines high-temperature aerobic fermentation and three-stage deodorization process to achieve more than 90% odour removal rate, which is especially suitable for the harmless treatment of high-concentration organic wastes such as livestock manure and kitchen waste.
Ammonia gas is dissolved in water and converted into stable ammonium hydroxide through multi-stage water washing device, weakening the pungent odor from the source.
For hydrogen sulfide, methyl mercaptan and other odor molecules that are difficult to dissolve in water, industrial-grade activated carbon is used for strong adsorption, which is stable and efficient.
Selected beneficial bacterial species decompose sulfur into low odor or odorless compounds, realizing the real “eating odor from the source”.
This system has been widely used in many large-scale farms and organic fertilizer production lines across the country, with stable operation, easy maintenance, and suitable for all kinds of harsh environments, which is truly “intelligent and environmentally friendly compost processing equipment”.
In addition to deodorizing performance, large deodorizing composting tanks also have the following advantages:
Fully closed tank, effectively preventing odor leakage and avoiding secondary pollution; at the same time, the wall of the tank adopts the broken bridge insulation technology, which has excellent corrosion resistance and can effectively isolate the temperature difference between inside and outside to enhance the stability of fermentation.
Built-in automatic temperature and oxygen control device, real-time monitoring and adjustment of fermentation conditions to ensure that the microorganisms are in the best active state, thus improving the efficiency and quality of composting.
The heat exchange device recovers heat energy generated during the fermentation process, which not only continuously maintains the required high-temperature environment, but also realizes energy recycling and significantly reduces operating energy consumption.
The whole composting process is carried out in a high temperature environment, which can effectively kill pathogenic microorganisms, realize the harmlessness of manure treatment, and ensure product safety and environmental protection.
5.High quality organic fertilizer output
The total content of nitrogen, phosphorus and potassium of organic fertilizer produced by Bolong composting tank is up to 12%, which is far more nutritious than common organic fertilizer, widely used in agricultural production, and it is the preferred fertilizer source for efficient green planting.
In 2024, a large-scale egg farm in Vietnam was interviewed by the environmental protection department several times because of the odor nuisance. After the introduction of Bolong’s large deodorizing composting tanks, the odor concentration in the fermentation area dropped by more than 80%, and the satisfaction of the residents was greatly improved. The project also passed the environmental protection acceptance, and was listed as the “Green Breeding Demonstration Project” by the local community.
At present, the environmental protection policy is becoming increasingly strict, the masses of environmental protection awareness is rapidly awakening, the breeding industry has entered the “air treatment just need” era. Choose a set of efficient, intelligent, environmentally friendly large deodorizing composting tanks, not only to protect the basis of compliant operation, but also an important step towards modernization and intelligent development of the farm.
