A process for controlling the composting air in a composting system, which comprises an aerobic composting reactor (101), consists of the following steps. The composting air is sucked out of the composting reactor (101), is pressed into an air washer (121), which cools the composting air with washing water, and then part of the composting air is withdrawn and the rest of the composting air is throttled, is mixed with fresh air and is recirculated to the composting reactor (101). This control ensures a very high degradation rate by controlling the supply of oxygen for the composting and the water content in the organic material, which results in a considerable generation of composting heat and evaporation of ammonia. The composting heat is transferred to a heating system via a heat exchanger and the ammonia is collected and used as a soil conditioner. |
