摘　　要：为探究二噁英(PCDD/Fs)合适的指示物,本文研究了国内两座生活垃圾焚烧电厂的两台循环流化床炉A、B的PCDD/Fs及氯苯(CBzs)排放特性.同时利用统计分析软件(SPSS)分析了PCDD/Fs浓度、TEQ浓度、CBz浓度之间的相关性.结果显示,在17种有毒PCDD/Fs中,2,3,4,7,8-P5CDF是最主要的二噁英同系物,在焚烧炉A、B中分别占毒性当量(TEQ)的28.97%—49.42%和45.56%—56.23%.氯苯的排放以二氯苯(DCBzs)、三氯苯(Tr CBzs)为主,其浓度是PCDD/Fs的几千倍.当用CBz作PCDD/Fs和TEQ的指示物进行一元线性回归分析时,发现部分指示物有很高的相关系数,R2最高可达0.8642.This paper investigated the emission characteristics of PCDD/Fs and chlorobenzenes（ CBzs） from two fluidized bed incinerators（ A and B） to find the appropriate indicators of PCDD/Fs. The correlations between PCDD/Fs concentrations,toxic equivalent（ TEQ） values and CBzs were analyzed by a Statistical Package for the Social Science（ SPSS）. The results showed that2,3,4,7,8-P5 CDF was the most important one of the 17 toxic congeners in the flue gas. It accounted for 28. 97%—49. 42% and 45. 56%—56. 23% of the TEQ in the incinerators A and B.Dichlorobenzenes（ DCBzs） and trichlorobenzenes（ Tr CBzs） were the major congeners for the CBzs emission,the concentrations of which were several thousand times that of PCDD/Fs. Linear regression analysis was performed using CBz as an indicator of PCDD/Fs and TEQ. It was found that some of the indicators had a high coefficient of determination（ R2）,up to 0.8642.
