    猪粪堆肥过程中NH3和H2S的释放及除臭微生物的筛选研究

    caracteristics of ammonia and hydrogen sulfide volatilization during composting of pig manure and screening of deodorizing microorganisms

    • 摘要: 为了治理粪便臭气污染,测定了猪粪好氧堆肥过程中NH3和H2S的释放量以及堆肥温度、pH值、含水率、水溶性铵态氮等指标。结果表明,NH3在前20天释放量占总释放量的84.6%、H2S在前13天释放量占总释放量的100%。因此,在堆肥初期的前20天是控制臭气的最佳时期。并从畜禽粪便、垃圾、土壤和堆肥中分离、纯化了一些微生物,经过初筛得到能利用NH3的微生物41株,经过复筛得到脱除H2S较好的细菌一株,与对照相比其去除率达85.7%,经鉴定该菌是松鼠葡萄球菌。

       

      Abstract: In order to alleviate pollution of manure odor, we determined the amount of NH3 and H2S emission, temperature, pH value, moisture content and water soluble NH4+-N content during aerobic composting of swine manure. The results suggest that the quantity of NH3 emission in the first 20 days accounts for 84.6% of the total NH3 emission,and the quantity of H2S emission in the first 13 days accounts for 100% of the total H2S emission. Consequently, the initial 20 days is an ideal period to control odor gas volatilization. Some microorganisms were isolated and purified from animal manure, garbage, soil and compost. Using selective medium, we screened primarily out 41 strains which could directly utilize NH3. One bacteria out of 41 strains which had a better capability of absorbing H2S was identified as StapHylococcus sciuri via second screening,which could reduce 85.7% of H2S emission compared with control.
