We determined the changes in polychlorinated biphenyl (PCB) concentrations in a mixture of sewage sludge and the organic fraction of municipal waste during composting and during anaerobic digestion. The processes were carried out on a laboratory scale. The PCBs were analyzed in the waste samples using gas chromatography-mass spectrometry. We evaluated the rates at which the PCB concentrations decreased during composting and during anaerobic digestion and compared the PCB degradation kinetics during these processes. The most important conclusion of this work is that anaerobic digestion is much more effective than composting at removing PCBs from a mixture of sewage sludge and the organic fraction of municipal waste.
我们测定了在堆肥和厌氧消化过程中，污水污泥与城市垃圾有机组分混合物中多氯联苯（PCB）浓度的变化。这些过程在实验室规模下进行。使用气相色谱 - 质谱联用仪对废物样品中的多氯联苯进行分析。我们评估了堆肥和厌氧消化过程中PCB浓度降低的速率，并比较了这些过程中PCB的降解动力学。这项工作最重要的结论是，在从污水污泥与城市垃圾有机组分的混合物中去除多氯联苯方面，厌氧消化比堆肥有效得多。
