The production and emission of volatile organic compounds (VOCs) were studied using an online monitoring method in a well-operated sludge composting plant. Results indicated that VOC production within the pile was different from emission at the pile surface. The total mass of VOC production was 1.09gCkgDM(-1), which was 2.3 times as high as the total mass of emission. The maximum production and emission masses occurred in the mesophilic phase of composting and were 444 and 202mgkgDM(-1)d(-1), respectively. VOC production and emission rates also varied rapidly at different times. The relationship of VOC production rates and time in an on/off aeration cycle at different periods could be expressed as a quadratic equation, while the emission rate could be expressed as a linear equation.
采用在线监测方法研究了挥发性有机化合物（VOCs）的产生和排放，该方法在一个运行良好的污泥堆肥厂中使用。结果表明，堆内 VOC 的产生与堆表面的排放不同。堆内总 VOC 产生量为 1.09gCkgDM(-1)，是排放量的 2.3 倍。最大的产生和排放质量出现在堆肥的中温阶段，分别为 444 和 202mgkgDM(-1)d(-1)。VOC 的产生和排放速率在不同时间也迅速变化。不同时期的开/停曝气周期中 VOC 产生速率与时间的关系可以用二次方程表示，而排放速率可以用线性方程表示。
