Co-composting of chicken manure, straw and dry grasses was investigated in a forced aeration system to estimate the effect of aeration rates on NH(3), CH(4) and N(2)O emissions and compost quality. Continuous measurements of gas emissions were carried out and detailed gas emission patterns were obtained using an intermittent-aeration of 30 min on/30 min off at rates of 0.01 (A1), 0.1 (A2) and 0.2 (A3) m(3)min(-1)m(-3). Concentrations of CH(4) and N(2)O at the low aeration rate (A1) were significantly greater than those at the other two rates, but there was no significant difference between the A2 and A3 treatments. CH(4) and N(2)O emissions for this mixture could be controlled when the composting process was aerobic and ammonia emissions were reduced at a lower aeration rate. Comparison of CH(4), N(2)O, NH(3) emissions and compost quality showed that the aeration rate of the A2 treatment was superior to the other two aeration rates.
鸡粪、秸秆和干草的共堆肥在强制通风系统中进行了研究，以评估通风速率对 NH(3)、CH(4) 和 N(2)O 排放和堆肥质量的影响。采用 0.01（A1）、0.1（A2）和 0.2（A3）m(3)min(-1)m(-3)的间歇通风（30 min 通气/30 min 停气），对气体排放进行了连续测量，并获得了详细的气体排放模式。低通气率（A1）下的 CH(4) 和 N(2)O 浓度明显大于其他两种通气率下的浓度，但 A2 和 A3 处理之间没有显著差异。当堆肥过程为好氧时，可以控制该混合物的 CH(4) 和 N(2)O 排放，并且在较低的通气率下减少氨排放。CH(4)、N(2)O、NH(3)排放和堆肥质量的比较表明，A2 处理的通气率优于其他两种通气率。
