Controlling ventilation is a critical aspect of the aerobic fermentation process used in the production of bio-organic fertilizer from animal waste and other organic materials. This process relies heavily on proper air circulation to maintain optimal conditions for microbial activity. Oxygen supply and airflow are essential elements that directly influence the efficiency and quality of the final compost product. The required ventilation rate depends on factors such as the organic content, volatility, and degradability of the raw materials used.
The primary functions of ventilation include: 1) supplying oxygen to support microbial metabolism and speed up the decomposition process; 2) regulating the temperature within the compost pile to prevent overheating or cooling; and 3) reducing moisture levels by removing excess water vapor. Insufficient ventilation can lead to poor microbial activity, lower temperatures, and incomplete breakdown of organic matter. On the other hand, excessive ventilation may cause rapid heat loss, which could slow down the fermentation process and reduce the effectiveness of pathogen elimination.
In practice, the recommended forced ventilation rate typically ranges from 0.05 to 0.2 cubic meters per minute per cubic meter of compost material. This range ensures a balance between maintaining adequate oxygen levels and preventing unnecessary heat loss.
To achieve effective ventilation control, several methods are commonly used: 1) natural aeration through open spaces or wind; 2) inserting ventilation pipes into the compost reactor; 3) using specialized turning machines to mix and aerate the pile; and 4) employing fans for forced air supply. Each method has its own advantages and is chosen based on the scale, type of materials, and desired outcome of the composting process.
