The concentration of volatile organic compounds (VOCs) during the composting of kitchen waste and pruning residues, and the abatement of VOCs by different compost biofilters was studied. VOCs removal efficiencies greater than 90% were obtained using composts of municipal solid waste (MSW) or MSW-pruning residue as biofilter material. An electronic nose identified qualitative differences among the biofilter output gases at very low concentrations of VOCs. These differences were related to compost constituents, compost particle size (2-7 or 7-20mm), and a combination of both factors. The total concentration of VOCs determined by a photoionization analyser and inferred from electronic nose data sets were correlated over an ample range of concentrations of VOCs, showing that these techniques could be specially adapted for the monitoring of these processes.
研究了在厨房垃圾和修剪残渣堆肥过程中挥发性有机化合物（VOCs）的浓度，以及不同堆肥生物滤器对 VOCs 的去除效果。使用城市固体废物（MSW）或 MSW-修剪残渣作为生物滤器材料，VOCs 的去除效率大于 90%。电子鼻在 VOCs 的极低浓度下识别出生物滤器输出气体之间的定性差异。这些差异与堆肥成分、堆肥颗粒大小（2-7 或 7-20mm）以及这两个因素的组合有关。光离子化分析仪测定的 VOCs 总浓度和电子鼻数据集推断的浓度在 VOCs 的广泛浓度范围内相关，表明这些技术可以特别适用于这些过程的监测。
