摘　　要：集约化猪场恶臭的生物处理可以在饲养的营养技术、饲养过程和粪便处理阶段分别处理,试验表明使用含有微生物制剂等成分的除臭剂为饲料添加剂,可使猪舍氨气和硫化氢分别降低38.6%和20.6%,调节池中氨气和硫化氢分别降低14.7%和20.4%,臭气浓度降低43.8%。而在猪舍和饲养过程中使用恶臭吸附剂直接放置于猪场环境中,可降低猪舍中的氨气和硫化氢浓度29.5%和30.4%,降低调节池中的氨气和硫化氢30.2%和0%,降低臭气浓度31.9%。在猪场污水处理阶段使用雾化除臭处理设备,可以降低调节池、贮粪池和水力筛池的氨气浓度14.7%、24.6%和48.2%,分别降低硫化氢浓度18.1%、25.8%和13.0%,同时降低猪场臭气浓度82.6%。Odor pollutants can be controlled in the early, middle and late raising-stage in a scaled pig farm. Tests and experiments showed that feed additives contained deodorant microorganisms and other chemical ingredients could reduce ammonia and sulfuretted hydrogen efflux 38.6% and 20.6% in pigsty, and 14.7% and 20.4% in wastewater adjusting tank respectively, meanwhile odor concentration was remarkable reduced 43.8%. When solid odor absorbers were positioned in rows in pigsty, the ammonia and sulfuretted hydrogen concentrations were reduced 29.5% and 30.4% in pigsty, and 30.2% and 0% in wastewater adjusting tank, odor concentration also remarkable reduced 31.9%. At the piggery wastewater treatment station, the deodorant fine spray was effluented from the odor biological equipment, the concentrations of ammonia was reduced 14.7%, 24.6% and 48.2%, and sulfuretted hydrogen was reduced 18.1%,25.8% and 13.0% in wastewater adjusting tank, excrement tank and screen tank respectively, odor concentration was reduced 82.6% obviously by the equipment.
