摘要
在规模化养猪业快速发展的同时产生了大量臭气,影响周围居民生活环境,危害人畜健康。目前,规模化猪场臭气治理技术主要集中在饲养管理技术、营养技术与集中收集处理技术。作者查阅了大量文献,联系实际生产,分析了臭气的主要成分、生成途径及臭气产生的主要影响因素,着重描述了氨气、硫化氢和粪臭素的危害;介绍了低蛋白质饲粮、低硫饲粮、低可发酵碳水化合物饲粮和不同类型的饲料添加剂对猪场臭气产生的影响,并将其对猪肠道臭气产生的控制机制进行了简要归纳;提出了改进饲养管理方法和智能收集处理系统对猪舍内臭气扩散过程的控制;概述了猪舍末端气体、固体和液体污染物的臭气集中管控处理技术,并对源头减排、过程控制、末端治理综合除臭技术的应用及臭气减排智能化管控技术进行了展望,旨在为规模化猪场臭气减排提供参考。
With the rapid development of large-scale pig farming,a large amount of odor is generated,which affects the living environment of surrounding residents and poses a threat to human and animal health.At present,the odor control technology of large-scale pig farms mainly focuses on feeding management technology,nutrition technology,and centralized collection and treatment technology.This article comprehensively references a large number of literature and combines practical production to analyze the sources,components,hazards,and influencing factors of odor.It introduces the dietary additives used to reduce the generation of odor in pig houses and the method of adjusting the proportion of dietary nutrients to promote the reduction of intestinal odor in live pigs.It proposes feeding management methods and intelligent processing systems for reducing odor in pig houses,and outlines centralized control and treatment technologies for reducing gas,solid,and liquid pollutants at the end of pig houses,and prospects were made for the application of comprehensive deodorization technologies for source reduction,process control,and end treatment,as well as intelligent control technologies for odor reduction,with the aim of providing reference for large-scale pig farm odor reduction.
