垃圾焚烧过程中氯苯与二噁英排放的相关性分析

Correlation Analysis of Chlorobenzene and Dioxin Emissions from MSW Incine ration

随着中国城市化进程的加快,生活垃圾产量日益增加,垃圾焚烧将成为主要的生活垃圾处理方式。大量国外的研究发现,在实际垃圾焚烧排放中,多种氯苯类物质与二噁英毒性当量之间存在良好的相关性,本文根据2台生活垃圾焚烧炉的实际排放情况,对焚烧炉烟气净化系统后烟气中的二噁英和氯苯含量进行检测,研究了两者的排放特性和相关性,建立了氯苯和二噁英毒性当量的关联模型,对其相关性进行研究,二氯苯、三氯苯普遍能够与二噁英毒性当量表现出良好的线性关联,而高氯代氯苯关联性并不佳。

With the acceleration of China＇s urbanization process, the production of household waste increases day by day, and waste incineration will become the main waste disposal method. A large number of foreign studies have found that there are good correlations between various chlorobenzenes and dioxin toxicity equivalence in actual waste incineration emissions. This paper is based on the actual discharge of two domestic refuse incinerators. The content of dioxin and chlorobenzene in the flue gas after the flue gas purification system was tested. The emission characteristics and correlation of the two were studied. The correlation model between the chlorobenzene and dioxin toxicity equivalence was established and its correlation was studied. Dichlorobenzene and trichlorobenzene generally exhibit a good linear correlation with the dioxin toxicity equivalency, while high chlorobenzene has a poor correlation.
