蛋鸡舍冬季CO_2浓度控制标准与最小通风量确定

中国现行的蛋鸡舍内CO2浓度控制的农业行业标准为1 500 mg/m^3,主要适用于传统的刮板式清粪鸡舍。目前新建、改建鸡舍都采用传送带清粪方式,鸡舍内的相对湿度和氨气等有害气体浓度均明显减少,其冬季最小通风量和舍内CO2浓度参数标准均有待重新研究。该文通过总结分析国内外相关学者对不同清粪方式蛋鸡舍内NH3、CO2浓度的测试数据,提出传送带清粪蛋鸡舍内CO2浓度取值建议,并根据CO2浓度平衡原理,提出该类蛋鸡舍冬季最小通风量的取值建议。结果表明：传送带清粪蛋鸡舍内CO2浓度参数控制标准建议可取5 000 mg/m^3;蛋鸡舍冬季连续通风最小通风量为0.40～0.50 m^3/（h·kg）。该研...

Summary:中国现行的蛋鸡舍内CO2浓度控制的农业行业标准为1 500 mg/m^3,主要适用于传统的刮板式清粪鸡舍。目前新建、改建鸡舍都采用传送带清粪方式,鸡舍内的相对湿度和氨气等有害气体浓度均明显减少,其冬季最小通风量和舍内CO2浓度参数标准均有待重新研究。该文通过总结分析国内外相关学者对不同清粪方式蛋鸡舍内NH3、CO2浓度的测试数据,提出传送带清粪蛋鸡舍内CO2浓度取值建议,并根据CO2浓度平衡原理,提出该类蛋鸡舍冬季最小通风量的取值建议。结果表明：传送带清粪蛋鸡舍内CO2浓度参数控制标准建议可取5 000 mg/m^3;蛋鸡舍冬季连续通风最小通风量为0.40～0.50 m^3/（h·kg）。该研究为中国新建、改建传送带清粪模式蛋鸡舍CO2浓度参数标准的取值以及调控蛋鸡舍冬季通风与保温矛盾等问题提供了参考依据。

The CO2 concentration is required to be below 1500 mg/m^3（Environmental Quality Standards for the Livestock and Poultry Farm of China, published in 1999） in layer hen houses where the manure is disposed by powered scraper, the litters generally need to remind and the drinking device has water leak. Consequently, moisture and NH3 levels in such barns are much high. Also, air temperature is much lower in winter, because the minimum ventilation rate is large in winter. However, the manure is cleaned daily in new poultry house with manure convey belt. Meanwhile, the aerial pollutants（CO2 and NH3） are reduced and the relative humidity is decreased. Indoor air quality in this kind of poultry house is dramatically improved. A new standard of CO2 concentration and the minimum ventilation rate of layer house with manure convey belt should be reconsidered. Determining the CO2 concentration standards for the manure conv
