摘　　要：针对生活垃圾焚烧企业烟气排放烟囱6个断面单点采样的试验结果,分析按照《固定污染源排气中颗粒物测定与气态污染物采样方法》(GB/T 16157—1996)多断面点采样与单一固定断面点采样对监测结果的影响。试验表明,烟道气在不同断面点质量浓度分布差异较大,相对于样品实际监测值,各断面点二噁英毒性当量浓度最大正偏差达到+306%,最大负偏差达到-96%,测定的18个断面点样品,只有2个样品与实际样品监测值相近。In this study,the influences of multi-sites sampling and fixed single site sampling for flue gases emitted from household waste incinerators was analyzed according to 'The determination of particulates and sampling methods of gaseous pollutants emitted from exhaust gas of stationary source'( GB / T 16157—1996).The results of six-sites sampling showed that spatial distribution of PCDD / Fs in flue gases varied considerably.The maximum of positive deviation was up to + 306% and the maximum of negative bias was- 96% compared with practical sample monitoring. Of all the 18 sites,only 2 had approximate results to practical samples.
