摘要
目前我国有机固废产量大、处理时间长,好氧堆肥是有机固废资源化利用的有效技术手段。氮素转化与损失是影响堆肥质量的关键,降低氮素损失有助于提高堆肥产品的质量。阐述了氮素转化原理,总结了厨余垃圾、剩余污泥及畜禽粪便等有机固废好氧堆肥中氮素转化的研究现状,并对控制氮素损失的研究提出了展望。
At present,our organic solid waste is produced in large quantities and takes a long time to process,aerobic composting is an effective technical tool for the resourceful use of organic solid wastes.Nitrogen transformation and losses are keys to compost quality,and reducing nitrogen losses will help to improve the quality of the compost product.This paper describes the principles of nitrogen transformation,concludes the current status of research on nitrogen transformation in aerobic composting of organic solid waste such as food waste,waste activated sludge and livestock manure,and presents an outlook on research to control nitrogen losses.
