为减轻大量禽畜废弃物中氨气流失对环境的污染,研究和优化了微生物与秸秆等辅料对氨气释放量的影响。结果表明,F468、M1?M9等除臭微生物能显著降低氨气的释放量,其中F468是最优微生物,其它微生物与F468的配伍并没有显著增强F468降低氨气释放量的能力,有些微生物还降低了其能力,因此选择单一微生物法降低氨气释放量。单独添加辅料对降低氨气的释放影响较小,辅料与微生物的配伍可大量降低氨气的释放量。5%的F468与10%的秸秆配伍在1?5 d降低88%的释放量。应用微生物与秸秆不仅降低氨气挥发对环境的危害,也是秸秆资源化利用的有效途径之一。
In order to reduce the environmental pollution caused by the loss of ammonia in a large amount of livestock waste, the effects of microorganisms, straw and other excipients on the release of ammonia were studied and optimized. The results showed that the deodorizing microorganisms such as F468 and M1? M9 could significantly reduce the release of ammonia, of which F468 was the optimal microorganism. The compatibility of other microorganisms with F468 did not significantly enhance the ability of F468 to reduce the release of ammonia. Some microbes also Reduce its ability, so choose a single microbial method to reduce ammonia emissions. Add accessories alone to reduce the release of ammonia has little effect, accessories and microorganisms compatibility can greatly reduce the release of ammonia. The compatibility of 5% F468 with 10% straw reduced the release by 88% after 1? 5 days. Application of microorganisms and straw not only reduce the harm of ammonia volatilization to the environment, but also one of the effective ways for straw utilization.
