Analysis of the Control Effect of Volatile Gas during Chicken Manure Composting
摘要
Abstract
To reduce the volatile organic compounds released from the composting and decrease its odor effectively, two methods of adding conditioner to the composting material such as chicken ma⁃nure and combination absorption system were utilized in this study. Results showed that the early stage of the chicken manure compositing which possesses the highest releasing rate of the ammonia was the most critical period of controlling the loss of nitrogen element. During this stage, the calcium superphosphate was added into the compositing. The highest releasing rate of the ammonia decreased by 16�8% and 28�1% respectively when the concentration of the calcium superphosphate added was 1% and 2%. Meanwhile, the compositing products of total nitrogen content and available phosphorus content increased, which improved compost quality significantly. During the chicken manure com⁃positing, the releasing gases were treated with three kinds of absorption solution and activated carbon adsorbent, and the removal rate of the volatile organic compounds reached 99�7%. Accordingly, this technology could be applied to remove malodorous gas in factory composting system.关键词
