吸附剂XF-4对不同季节奶牛舍中NH_3和CO_2的吸附效果

Adsorption Capacity of Adsorbent XF-4 to NH_3 and CO_2 in Cowshed

为吸附剂XF-4在养殖生产上控制空气污染的推广应用提供参考,进行了吸附剂XF-4对不同季节奶牛舍中NH3和CO2的吸附效果试验。结果表明：1kg吸附剂XF-4吸附NH3、CO2的量春季分别为15.69g和2.30g,夏季为10.24g和1.70g,秋季为18.36g和3.29g,冬季为20.65g和4.38g。吸附剂XF-4吸附NH3、CO2的重量分别与pH值呈极显著和显著正相关,与湿度呈显著和极显著正相关,与温度呈极显著和显著负相关。吸附剂XF-4在悬挂47h吸附效果最好,悬挂31h需要更换吸附剂。

To provide references for popularization and application of adsorbent XF-4for controlling air pollution in livestock production,the absorption efficiency of XF-4was tested to NH3 and CO2in cowshed in different seasons.Results：The absorption amount of 1kg XF-4 to NH3 and CO2 was respectively15.69 gand 2.30 g in Spring,10.24 g and 1.70 g in Summer,18.36 g and 3.29 g in Autumn and 20.65 g and 4.38 g in Winter.The weight of NH3 and CO2 was of very significant and significant positive correlation with pH respectively,significant and very significant positive correlation with humidity,very significant and significant negative correlation with temperature.The best adsorbent time of XF-4 was suspension for 47h,XF-4should be replaced after suspension for 35 h.
