中文摘要:NH3排放系数是对规模化养殖场NH3排放量估算、NH3减排方法与技术应用效
果评估的有效方法之一。通过在模拟实际生产动物人工气候室对3种不同地面结构的育肥猪
舍NH3排放相关数据的连续在线检测,研究了不同地面类型猪舍内NH3排放与主要影响因
子的相关性及其排放系数。研究得出半缝隙地面猪舍、实心地面猪舍、生物发酵床猪舍内NH
3排放系数分别为:(947±709)、(1123±423)、(427±209)g/(d
pig)。 |

Abstract:Ammonia (NH3) and other air pollution emissions from concentrated animal fee
ding operations (CAFOs) are becoming more and more serious with the rapid develo
pment of livestock and poultry production in recent years. The ammonia emission
factor is one of the effective methods for estimating ammonia emissions from CAF
Os and evaluating of emission reduction technologies. A continual monitoring sys
tem of the NH3 concentration and environmental parameters is used in this rese
arch, and the ammonia emission factors and impact factors of the three types of
floor systems in the pig buildings are studied. Mean daily emissions per pig fat
tened on the semi slatted floor system, concrete floor system, and deep litter
system are (947±709), (1123±423), (427±209)g/(d?pig), respectively. |
Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
