| 摘 要： | 与复杂的混合生活垃圾相比,厨余垃圾成分较单一,需要针对性的采样方法.本研究基于生活垃圾分类背景,在《生活垃圾采样和分析方法》(CJ/T 313—2009)的基础上,就采样位点和采样节点数对分类存放的厨余垃圾采样的影响展开研究.研究结果表明,仅采集垃圾桶中间位点的样品不具有代表性,不同情景应有不同的采样策略.当厨余垃圾流节点数少于2时需采集所有节点,当厨余垃圾流节点数为3~7时需采集2个节点,而当厨余垃圾节点数为8~18时需采集3个节点,均少于CJ/T 313—2009中要求的采样节点数.厨余垃圾的总量增大,则其最少采样节点数相应上升,但最少采样点受到厨余垃圾流节点数的制约.

| Abstract: | Compared with the complicated mixed domestic waste, kitchen waste needs a designated sampling method due to its single composition. Based on the background of domestic waste classification and the standard sampling and analysis methods for domestic waste (CJ/T 313-2009), this study was carried out to investigate the effect of sampling points and positions on the classified kitchen waste's nature. It is indicated that the sample only from the middle position of container is not representative, and sampling strategy should differ with the kitchen waste points. Namely, all points should be sampled when the kitchen waste is no more than two, only two points should be sampled when it is 3 to 7, while three points must be sampled when it is 8 to 18. The sampling points are obviously less than the same scenarios defined in CJ/T 313-2009. The minimal sampling points increases with the increasing of kitchen waste amount, but the sampling position still depends on the sampling points. |
