Description

Technology Field

[0001] The present invention relates to a fermentation system, and more specifically, to an aerobic fermentation system for efficiently composting livestock manure. The system of the present invention includes an environmentally friendly composting technology designed to promote the maturation of livestock manure, reduce odors and minimize greenhouse gas emissions, and produce mature organic fertilizer. Background Technology

[0002] Composting livestock manure falls under the category of resource recovery technology within livestock manure treatment technologies. The primary reason for utilizing livestock manure through composting is to convert the organic matter and nutrients contained within it into useful fertilizer resources while minimizing their negative impact on water, soil, and atmospheric environments. Through the composting process, organic matter within the manure is stabilized, pathogenic microorganisms are eliminated, and the manure is transformed into mature compost with soil-improving effects, making it suitable for agricultural use.

[0003] However, if livestock manure is not properly composted or is managed improperly, it can lead to various environmental problems.

[0004] First, water pollution problems may arise. Livestock manure contains large amounts of nitrogen (N) and phosphorus (P), so if composting is not properly carried out, there is a high likelihood of it being washed away by rainfall. In this case, it may flow into rivers and lakes, promoting eutrophication and inducing algal blooms, thereby degrading the aquatic ecosystem.

[0005] Second, there is the issue of soil contamination. If livestock manure that has not been fully decomposed is used as compost, uncomposted organic matter can enter the soil, causing foul odors and the proliferation of harmful microorganisms. Furthermore, there is a concern that heavy metals and antibiotic residues in the manure may seep into the soil, potentially lowering the productivity of agricultural land in the long term.

[0006] Third, atmospheric environmental issues cannot be overlooked. If livestock manure is improperly treated, malodorous substances such as ammonia (NH₃) and hydrogen sulfide (H₂S) may be generated during the decomposition process. This not only adversely affects the surrounding living environment but can also cause inconvenience to residents in nearby areas. Furthermore, it has the potential to contribute to climate change by increasing the emission of greenhouse gases such as methane (CH₄) and nitrous oxide (N₂O).

[0007] As failing to properly treat livestock manure can lead to various environmental problems, the development and application of effective resource utilization technologies, including composting, are essential. In particular, aerobic fermentation is attracting attention as an environmentally friendly livestock manure treatment technology because it offers advantages such as odor reduction, rapid maturation, and reduced greenhouse gas emissions compared to anaerobic fermentation.

[0008] The aforementioned technical configuration is provided as background technology to aid in understanding the present invention and does not constitute prior art widely known in the technical field to which the present invention belongs. Prior art literature

[0009] Korean Patent Publication No. 2023-0117938 (Ian Engineering Co., Ltd.) August 10, 2023. The problem to be solved

[0010] The biggest problem in the treatment of livestock manure is the environmental and economic burden caused by odors generated during composting, prolonged maturation periods, greenhouse gas emissions, and the persistence of pathogens. Some existing composting methods are based on anaerobic fermentation, which results in severe odor generation and slow maturation rates, requiring a long time to obtain fully matured compost. Furthermore, incomplete composting raises the possibility of pathogens entering agricultural land without being eliminated, and the use of immature compost can lead to soil contamination and impaired crop growth.

[0011] To address these issues, the present invention proposes a technology that utilizes an aerobic fermentation system to promote the efficient decomposition and stable maturation of livestock manure, while minimizing environmental problems. The system of the present invention maximizes microbial activity through optimized air supply and temperature control, thereby enhancing the maturation speed and reducing odor and greenhouse gas emissions. means of solving the problem

[0049] A control method for promoting the maturation of livestock manure is described below.

[0050] The livestock manure aerobic fermentation system of the present invention includes a control method that optimizes air supply amount, supply time, temperature, humidity, and microbial activity to promote rapid and uniform maturation of livestock manure.

[0051] Air supply volume and cycle control controls the blower motor (230) of the blow unit (200) to adjust the air supply volume in real time. During the initial fermentation stage, a high-speed air supply mode is activated to promote microbial growth, and as maturation progresses, it switches to a low-speed air supply mode to ensure fermentation stability. Air supply is provided intermittently, and the supply-stop cycle (e.g., 30 minutes of operation, 10 minutes of stop) is automatically adjusted to create an optimal oxygen supply environment.

[0052] Temperature and humidity detection and control are achieved by placing temperature and humidity sensors inside the livestock manure to collect data in real time. The air supply volume is controlled by adjusting the rotation speed of the blower motor (230) so that the internal temperature is maintained within the range of 55 to 65°C. When humidity rises above a certain level (e.g., 60%), the air supply volume is increased to promote moisture evaporation and maintain an optimal fermentation environment.

[0053] Real-time monitoring and automatic control of the composting state analyzes the activity of aerobic microorganisms through an oxygen concentration sensor inside the livestock manure, and automatically increases the air supply amount when the oxygen concentration decreases to 5% or less. By utilizing a gas sensor (NH₃, H₂S detection), if an excessive amount of odorous substances is detected, the operating cycle of the blow unit (200) is adjusted to induce odor reduction.

[0054] Data-driven artificial intelligence (AI) optimization control stores and analyzes fermentation progress data to automatically generate optimal air supply patterns based on seasonal and environmental changes. By applying an AI-based control system, operating costs can be reduced and fermentation efficiency maximized by automatically adjusting the air supply volume and cycle according to the condition of the livestock manure.

[0055] The multi-air injection method for uniform maturation enables evenly distributed oxygen supply by independently controlling multiple air supply lines (140) instead of the conventional single supply method. By allowing the flow rates of the joint line (130) and individual air supply lines (140) to be individually adjusted, optimal air distribution is maintained according to the height and density of the sediment.

[0056] As such, it is obvious to those skilled in the art that the present invention is not limited to the described embodiments and can be modified and varied in various ways without departing from the spirit and scope of the invention. Accordingly, such modified or varied embodiments should be deemed to fall within the scope of the claims of the present invention. Explanation of the symbols
