摘　　要：研究土壤生物过滤去除畜禽养殖臭气,旨在为土壤生物滤体除臭装置主要结构参数和运行参数及其优化配置提供依据。建立能同时进行多个处理的生物过滤除臭实验装置,分析影响土壤生物过滤法除臭效果的环境因子。结果表明,活性滤料组合草腐土75%,珍珠岩20%,黑炭5%,滤层高度1 000 mm,滤料表面负荷18 m3/(m2.h),滤料湿度55%的条件下,主要恶臭气体和温室气体释放物NH3、CH4、H2S和CO2去除率>95%,CO和NO2去除率>85%,与畜禽臭气共同扩散的总挥发性有机物(TVOC)、可吸入颗粒物(PM10)和总悬浮物(TSP)去除率>95%,系统排出气体的臭气浓度7.5～8.0,均符合达标排放要求。系统加湿策略应控制滤料湿度(52±3)%,不会出现气道"短路"现象,除臭效果稳定。To supply basis for primary structure parameters, operating parameter and their optimizing configuration, efficacy of soil bio-filtratiou on odor removal from livestock and poultry was studied. A bio-filtration deodorization tester, which can carry through multi-treating simultaneously, was set up for analyzing environmental factors of deodorization effect of soil bio-fihration process. The results show that when filter material is 75% of humus, 20% of pearlite and 5% of black wood charcoal, filtering layer height is 1 000 ram, load factor of filter material is 18 m3/（m2 · h） , filter material humidity is 55% , the removal rate of NH3, CH4, H2S and CO2 is more than 95% , that of CO and NO2 is more than 85%. The total volatility organic substance （TVOC） , inhalable particulate matter（PMl0） and total suspended matter （TSP） diffused with odor can be removed more than 95%. Odor concentration is 7.5 - 8.0. The odor discharged by system reach the discharge standard. Control filter material humidity in （52± 3 ）0/0 , airway ＂ short circuit＂ phenomenon won＇t come out, deodorization effect will be stable.
