摘要
堆肥化是污泥处置中的一种有效的资源回用方法,但是在堆肥化过程中N的损失可大大降低堆肥的农用价值,进而限制了污泥堆肥的使用。本文对污泥堆肥化过程中,N素的转变与损失机理采用生化反应电子计量学进行了探讨,并且讨论了固定N源、降低N素损失、提高堆肥农用价值的方法。
Composting is an effective alternative for treating sludge to recycle it as resource, but the loss of nitrogen in composting may greatly affect agricultural value of the compost, thus limiting the use of sludge as manure. In this paper, the mechanism of nitrogen loss in composting is analyzed by using electronic stoichiometry of biochemical reactions,and techniques for nitrogen conservation are explored as well.
