畜禽养殖舍是重要的氨气(NH3)排放源,了解畜禽舍NH3排放特性及其减排措施对于畜禽健康生产和环境健康均具有重要意义.本文综述了国内外有关猪、鸡、牛3种主要畜禽养殖舍内的NH3排放特性,对于不同畜禽舍内影响其NH3排放的关键影响因素进行了探讨,并对3种畜禽舍的NH3排放因子进行了比较,总结了当前广泛采用的各类畜禽舍内的NH3减排技术,包括从源头的饲料优化、排泄后粪便添加剂使用、舍内空气净化处理以及外排空气过滤装置等,构建了全方位的畜禽舍NH3减排措施体系,对于了解畜禽舍NH3排放特性,以及减排措施的选择具有重要参考意义.%Livestock houses are an important ammonia ( NH3 ) emission source, understanding the ammonia e-mission characteristics and mitigation technologies is of high importance to the livestock healthy production to-gether with achieving high environmental benefits.The NH3 emission characteristics of three major livestock houses, including pig, poultry and cattle houses were reviewed in this paper, and the key influencing factors for NH3 emission in each livestock house also were discussed and compared.The commonly used in-house NH3 mitigation technologies were summarized in this review.The mitigation technologies included the feed optimiza-tion on source, using the manure additive after manure being excreted, and the air cleaning infrastructures and the exhaust air filtering devices, to build a comprehensive mitigation system for livestock house NH3 emission. The result of this study was of high importance for understanding the NH3 emission characteristics from live-stock houses, and also for a reasonable choice of mitigation technologies for livestock house NH3 emission.
