筒仓式堆肥反应器不同通风量对堆肥效果的影响
Composting effects of using pilot silo reactor by different ventilation rate
摘要
Abstract
In this research, a pilot silo composting reactor and chicken manure with 70％ moisture content were used as raw materials for a composting trial.The focus of the study was on the effect of different ventilation rates on composting.Three different ventilation rates (12, 6, and 2.4) m3 · min-1 were used to pass air into the compost.The results of the research are as follows.A reasonable ventilation rate could effect a rapid composting fermentation process and the ventilation rate of 12 m3 · min-1 had the best composting effect.The TN content of the compost pile was decreased at treatment ventilation rates of (6 and 2.4) m3 · min-1.The results proved that both the latter ventilation rates could not meet the oxygen demand for fast composting fermentation, which led to anaerobic fermentation during the composting process.The ventilation rate of 6 m3 · min-1 achieved the largest increase of TP content, which shows that this experimental treatment reduced the loss of phosphorus and increased the amounts of effective phosphorus in the material.Compared with the other two experimental treatments, the ventilation rate of 12 m3 · min-1 produced a longer high temperature period (≥50 ℃), a greater amount of organic matter degradation, a higher increase of TP and TN content, and a higher rate of seed germination.All these results prove that the ventilation rate of 12 m3 · min-1 has the best composting effect.关键词
