| 摘 要： | 畜禽粪便高温好氧堆肥过程中氨气的排放不仅污染环境,而且会降低有机肥氮素含量。因此,控制好氧堆肥过程中氨挥发是降低氮损失及减少堆肥周边环境恶臭的关键。为研究膜覆盖对畜禽粪便好氧堆肥过程氨气挥发的影响,以猪粪和小麦秸秆为试验原料,采用具有选择渗透性的Gore膜作为覆盖材料,在实验室好氧堆肥反应器系统中进行了为期27 d的好氧堆肥试验。试验设置覆膜组和对照组,采用开启1 h、关闭1 h间歇通风方式,通风速率为3 L/min,重点监测堆肥过程堆体温度、氧浓度和NH3排放速率等。研究表明:覆膜组比对照组高温期持续时间略长,更有利于杀死堆体有害病原菌;相比于对照组,覆膜组NH3排放量减少18.87%;相比于温度峰值出现的时间,两组试验NH3峰值出现时间均延后,且覆膜组延后时间更长。

| Abstract: | The emission of ammonia in manure high temperature aerobic composting not only polluted the air but also reduced the nitrogen content of organic fertilizer. Therefore, the control of composting process of ammonia volatilization is the key of reducing nitrogen loss and environment ordor emission. In order to study the effect of membrane covered on reducing the emission of ammonia in manure aerobic composting, pig manure and wheat straw were used as experimental materials, and Gore film with selective permeability was used as covering material, the aerobic composting trial was carried out in a lab-scale intelligent membrane-covered aerobic composting reactor system for 27d. There were membrane-covered treatment and control treatment in this trial. Air blown at an hourly interval (flow velocity of 3L/min through the pipe at the bottom of the reactor diffused through the composting material to maintain aerobic conditions. The composting temperature, oxygen content and ammonia concentration were measured during the composting. The results showed that the high temperature duration of the membrane-covered group was longer than that of the control group, and it was more beneficial to kill the harmful pathogens. Compared with the control group, the NH3 emission in the membrane-covered group was decreased by 18.87%. Compared with the peak time of the temperature, the peak time of NH3 peak in both groups was delayed, and the delay time of the membrane-covered group was longer, and the phenomenon that peak value of NH3 lagged temperature was further revealed. |
