几种新型除臭剂对氨气去除效果的比较研究

Comparative Study on Ammonia Removal Effect of Several New Deodorants

摘要: 目的：探讨几种新型除臭剂对氨气去除效果及机制，以期为除臭剂的推广使用提供参考依据。方法：向充满氨气的密封装置内分别喷洒三种除臭剂，用氨气检测仪持续监测装置内氨气的浓度变化。比较三种除臭剂的除臭效果，采用高通量测序技术对三种菌剂进行测序，比较各组菌群的多样性及丰度。结果：3种除臭剂对氨气的去除效率由高到低依次为和润产品3 (hr3)、和润产品2 (hr2)、和润产品1 (hr1)；hr1的物种数量最多，物种多样性最高；hr2的物种数量最少，物种多样性最低；hr3居中；hr3菌群中厚壁菌门的乳杆菌属含量较高。结论：和润公司提供的三种除臭剂均能高效的去除氨气，以hr3的除臭效率最高；hr3除臭效率高的可能原因是乳杆菌属含量较高。

Abstract: Objective: To investigate the effect and mechanism of several new deodorants on ammonia removal, in order to provide reference for the promotion and use of deodorant. Method: Three kinds of deo-dorizers were sprayed into the sealed device which is filled with ammonia gas, and the ammonia gas concentration in the device was continuously monitored by the ammonia gas detector. Comparing the deodorizing effects of three kinds of deodorants, three kinds of microbial agents were sequenced by high-throughput sequencing technology, and the diversity and abundance of each group were compared. Results: The removal efficiency of ammonia from three deodorants was from Herun 3 (hr3), Herun 2 (hr2), and Herun 1 (hr1); hr1 has the largest number of species and the highest species diversity. hr2 has the lowest number of species and the lowest species diversity. hr3 is in the middle. The content of lactobacillus in firmicutes was higher in hr3. Conclusion: The three deodorants provided by herun company can remove ammonia gas efficiently, and hr3 has the highest deodorization efficiency. The possible reason for hr3’s high deodorization efficiency is the high content of lactobacillus.
