摘要
好氧堆肥是通过微生物活动将畜禽粪便降解转化为有机肥料的过程。氨挥发是造成堆肥氮素损失的重要途径,不仅会降低有机肥的肥效而且会造成臭气扩散、雾霾、气候变化等环境问题。因此,采取措施防止好氧堆肥过程中氨的挥发至关重要。综述了好氧堆肥过程中氮素转化的微生物机制和影响因素以及不同措施对氨挥发的影响,为优化堆肥工艺,减少氨挥发和提高资源回收效率提供理论依据,并指出了不同措施可能存在的问题以及未来的研究方向。
Aerobic composting can degrade and convert livestock and poultry manure through microbial activities to produce organic fertilizers.Ammonia volatilization is an important route of nitrogen losses during composting,which will not only reduce the quality of organic fertilizers,but also cause environmental problems such as odor diffusion,haze,and climate change.Therefore,it is very important to take measures to prevent ammonia volatilization during aerobic composting.The microbial mechanisms and influencing factors of nitrogen transformation during aerobic composting and the effects of different measures on ammonia volatilization were reviewed,which provided a theoretical basis for optimizing composting process,reducing ammonia volatilization,and improving resource recovery efficiency.The possible problems of different measures and future research directions were pointed out.
