摘要:

对某省52家焚烧企业（21家生活垃圾和31家危险废物）排放烟气数据进行了分析，结果表明，两类焚烧企业二噁英类17种单体分布有所不同，生活垃圾焚烧烟气中浓度较高的是O₈CDD和O₈CDF；危险废物焚烧烟气中较大的是2，3，4，7，8-P₅CDF、2，3，7，8-T₄CDD和1，2，3，7，8-P₅CDD；两类焚烧企业二噁英类单体对I-TEQ贡献最高的都是2，3，4，7，8-P₅CDF，贡献率分别为0.7%～45%和10%～67%；两者的17种二噁英类与I-TEQ的相关性分析表明，1，2，3，7，8-P₅CDF在2类焚烧炉中与I-TEQ均存在较高的相关性，其相关系数分别0.932和0.927，可以作为潜在的测定指示物。

Abstract:

The emission data of flue gas firn 52 incineration(21 domestic waste and 31 hazardous waste) in a province were analyzed, we found that the distribution of 17 monomers of dioxins in the two types of incineration enterprises was different, O₈CDD and O₈CDF showed higher concentrations in the flue gas produced by incineration of domestic waste, while the larger ones in the hazardous waste incineration flue gas were 2,3,4,7,8 P₅CDF, 2,3,7,8 T₄CDD and 1,2,3,7,8 P₅CDD. Regardless of whether it is domestic waste or hazardous waste incineration, the dioxin monomer 2,3,4,7,8 P₅CDF contributed the highest to I TEQ, with the contribution rates of 0.7 % to 45 % and 10 % to 67 %, respectively. The correlation analysis between the 17 dioxins and I TEQ of the two showed that 1,2,3,7,8 P₅CDF had a high correlation with I TEQ in the 2 incinerators, and the correlation coefficients were 0.932 and 0.927, respectively, showing that it can be used as a potential indicator of measurement.
