With the rapid development of animal husbandry, the emission of livestock and poultry manure increases year by year, which brings great pressure to the ecological environment. According to statistics, the annual emission of livestock and poultry manure in the world is about 3.05 billion tons, but the actual treatment is less than 35%. This situation not only seriously pollutes the environment, but also wastes a large amount of valuable agricultural resources.
As an effective resource treatment method, composting has gradually become the key to solve this problem. However, traditional composting has many challenges in the treatment process. Therefore, how to improve the composting efficiency and reduce the harmful emissions has become the focus of the current research and practice of livestock and poultry manure composting.
With the rapid development of animal husbandry, the emissions of livestock and poultry manure have increased dramatically, and the traditional composting methods have been unable to meet the increasingly severe environmental requirements. Although composting, as a harmless and resourceful treatment method, can convert livestock and poultry manure into organic fertilizer and improve soil quality, it still faces many challenges in practical application.
First of all, the fermentation cycle of compost is long and the processing efficiency is low, resulting in a large amount of manure that cannot be effectively processed in a timely manner. A more prominent problem is that a large amount of malodorous gases, especially ammonia and hydrogen sulfide, are generated during the composting process, and these harmful gases not only pose a serious threat to the environment and the health of humans and animals, but also reduce the fertilizer efficiency and agricultural value of compost. The emission of malodorous gases is often difficult to control, and the spread of odor is very rapid, resulting in pollution of the surrounding environment. This problem has become the biggest bottleneck of traditional composting technology, and is also the key problem of livestock and poultry manure treatment research.
Bolong has more than 30 years of experience in livestock and poultry harmlessness, and in 2015, we independently developed our own high temperature aerobic fermentation tank, which can efficiently convert animal manure into high-quality organic fertilizer in only seven days, which greatly shortens the long period of time required for traditional composting and significantly improves the quality of compost.
Each fermentation tank is equipped with an advanced spray tower deodorization system. Utilizing the principle of water solubility, it effectively treats harmful gases such as ammonia and a small amount of hydrogen sulfide produced during aerobic fermentation, and is capable of removing most odors.
Later on, after research and development, a new gas deodorization system was developed. On the basis of ammonia solubility in water, activated carbon was added as an adsorption medium in the system, especially for substances such as hydrogen sulfide and methyl mercaptan, which are difficult to be absorbed directly by water but have strong irritating odors, and activated carbon’s powerful surface and internal pore structure was used to capture and immobilize these pollutants, which greatly enhanced the overall deodorization effect.
It is also worth mentioning that Bolong gas deodorization system integrates cutting-edge microbial deodorization technology. Specific deodorizing bacteria, carefully selected and cultivated, can efficiently convert the residual hydrogen sulfide and sulfur in methyl mercaptan in the air into odorless or low-odor compounds, thus solving the malodor problem that has plagued the industry for a long time from the root.
Since its launch, this new gas deodorization system, which integrates the dual advantages of physical adsorption and biodegradation, has received a warm response from the market.
Advanced deodorization system naturally cannot be separated from the support of energy efficient manure fermentation system. Bolong high-temperature aerobic fermenter, using aerobic microorganisms aerobic fermentation principle, so that microorganisms in the appropriate temperature, humidity and sufficient oxygen environment to rapidly multiply, decomposition of livestock and poultry manure and carcasses in the organic matter, proteins and other substances, so as to effectively harmless treatment of livestock and poultry waste.
Different from the traditional composting method, Bolong’s fermentation system can quickly convert livestock and poultry manure into high-quality organic fertilizer in just seven days, which greatly improves the efficiency of resource utilization of waste. This rapid conversion not only meets the needs of sustainable development of modern agriculture, but also promotes the practice of green agriculture.
In addition, Bolong’s highly efficient and environmentally friendly fermenters are equipped with an innovative heat exchange system. In this system, the exhaust gases are condensed by a special device, which reduces the emission of harmful gases. The remaining exhaust gases then enter our deodorization system for further treatment.
The heat released during the condensation process is efficiently recovered and reintroduced into the fermentation system, promoting internal heat recycling. This recycling mechanism avoids the wastage of electrical energy caused by the prolonged operation of the heating fan, and further reduces energy consumption, achieving the double effect of energy saving and environmental protection.
With the innovative gas deodorization technology and energy efficient fermentation system, Bolong has broken through the major challenges faced by traditional composting in the treatment of livestock and poultry manure. Whether it is the removal of malodorous gases or the rapid conversion of waste, Bolong provides a sustainable, environmentally friendly and efficient solution.
