摘要

摘要: 将陈腐垃圾与生活垃圾协同焚烧是妥善腾退填埋场、缓解城市土地资源紧缺的重要方式之一。利用生活垃圾焚烧设施开展掺烧陈腐垃圾试验,按照0、10%、20%、25%、30%掺烧比例,分析掺烧对烟气中二噁英及其他污染物的排放影响。结果表明:颗粒物、SO₂、HCl、NO_x和二噁英浓度均随陈腐垃圾掺烧比例提高而逐渐上升。当掺烧30%时,PCDD/Fs毒性当量浓度约为0.13 ng-TEQ/m³,超过GB 18485-2014《生活垃圾焚烧污染控制标准》中排放限值。掺烧比例从0提高至20%,炉内PCDD/Fs生成量增加,处理设施入口毒性当量浓度升高14%,而烟气处理工艺对其去除率仍超过99%。掺烧陈腐垃圾在一定程度上促进了从头合成(De novo)反应。为确保掺烧烟气中污染物达标排放,应充分考虑陈腐垃圾的填埋时间、性质、热值、垃圾焚烧及污染防治技术等因素。

Abstract: Co-incineration of aged refuse and domestic waste is one of the important ways to properly vacate the landfill and alleviate the shortage of urban land resources.The domestic waste incineration facility was used to carry out the test of co-incineration of aged refuse and domestic waste.According to the aged refuse proportion of 0,10%,20%,25%,and 30%,the impact of co-incineration on the emission of dioxin and other pollutants in the flue gas was analyzed.The results showed that the concentrations of particulate matter,SO₂,HCl,NO_x,and dioxin gradually increased with the increase of aged refuse co-incineration proportion,but they all met the standard limit.When mixed with 25% and 30% of aged refuse,the toxic equivalent concentration of PCDD/Fs was close to 0.1 ng-TEQ/m³and 0.13 ng-TEQ/m³ respectively.The proportion of mixed combustion increased from 0 to 20%,the generation of PCDD/Fs in the furnace increased,the concentration at the inlet of the treatment facility increased by 14%,and the removal rate of flue gas treatment process exceeded 99%.The De novo reaction was promoted,to some extent,by burning aged refuse.In order to ensure that the pollutants in the mixed combustion flue gas complied with the standard,factors such as the landfill age,nature and calorific value of the aged refuse,incineration and pollution prevention technology should be fully considered.
