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O<sub>8</sub>CDD和O<sub>8</sub>CDF;危险废物焚烧烟气中较大的是2,3,4,7,8-P<sub>5</sub>CDF、2,3,7,8-T<sub>4</sub>CDD和1,2,3,7,8-P<sub>5</sub>CDD;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-P<sub>5</sub>CDF,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-P<sub>5</sub>CDF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。

Study on Emission Characteristics of Dioxins from Domestic Waste and Hazardous Waste Incineration

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, O<sub>8</sub>CDD and O<sub>8</sub>CDF 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 P<sub>5</sub>CDF, 2,3,7,8 T<sub>4</sub>CDD and 1,2,3,7,8 P<sub>5</sub>CDD. Regardless of whether it is domestic waste or hazardous waste incineration, the dioxin monomer 2,3,4,7,8 P<sub>5</sub>CDF 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 P<sub>5</sub>CDF 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.
