CA-1生物除氨节能净化机除氨效果的观察研究

Observation on ammonia removal effect of CA-1 biological ammonia removal energy saving purifier

目的观察CA-1生物除氨节能净化机对比格犬饲养室内的除氨净化效果,为大动物饲养环境控制提供理论依据。方法将16只普通级比格犬随机分成两组,分别饲养于约15 m2的普通饲养室内。将配置CA-1生物除氨节能净化机的饲养室作为实验组,另一饲养室作为对照组。根据饲养室设定的不同换气及冲洗次数观察生物除氨节能净化机的除氨效果,试验期为27 d。结果在换气次数设定为5次/h的情况下,实验组的平均氨气浓度均低于对照组,差异有统计学意义(P=0.0 037<0.05)。在换气次数设定为10次/h,每天冲洗1次和2次的情况下,实验组的平均氨气浓度均低于对照组,差异有统计学意义(P=0.0 079<0.05)。在换气次数设定为20次/h,每天冲洗1次的情况下,实验组的平均氨气浓度均低于对照组,差异有统计学意义(P=0.031<0.05)。结论 CA-1生物除氨节能净化机可以在一定程度上降低大动物饲养室内的氨气浓度。

Objective To observe the ammonia removal effect of CA-1 biological ammonia removal energy saving purifier,and provide a theoretical basis for the control of large animal feeding environment. Methods A total of 16 beagle dogs were randomly divided into two groups and fed in two 15 m2 ordinary feeding rooms. The feeding room with a CA-1 biological ammonia saving purification machine was taken as the experimental group,the other feeding room as the control group. The ammonia removal effect of the biological ammonia removal energy-saving purifier was observed according to the different ventilation and washing times set in the breeding room. The total observation was 27 days. Results The average ammonia concentration of the experimental group was significantly lower than that of the control group when the ventilation frequency was set to 5 times per hour,and the difference was statistically significant（ P = 0. 0 037 0. 05）. When the air exchange rate was set 10 times per hour and the room was washed 1 or 2 times,the average ammonia concentration in the experimental group was significantly lower than that in the control group,and the difference was statistically significant（ P = 0. 0 079 0. 05）. When the air change frequency was set 20 times per hour and the room was washed only once,the average ammonia concentration in the experimental group was significantly lower than that in the control group,and the difference was statistically significant（ P = 0. 031 0. 05）. Conclusion The CA-1 biological removal ammonia energy purification machine can reduce the ammonia concentration in the large animal feeding room to some extent.
