| 摘 要： | 对流化床垃圾焚烧炉中PAHs的排放特性进行了研究 .结果表明 ,烟囱烟气为流化床垃圾焚烧炉PAHs排放的主要途径 ,日排放量要高于其它途径 1— 2个数量级 ,且以低分子量物质为主 .脱除剂的添加对烟气中PAHs有减少的作用 ,但却增加了循环出口水中PAHs含量 .不同工况时PAHs环境排放毒性有变化 ,垃圾与煤混烧大于全煤 ,添加脱除剂大于未添加工况 ,但少于垃圾比例高的工况 .垃圾比例越高 ,毒性越大

| Abstract: | PAHs emission performance of a fluidized bed incinerator has been investigated.The results indicate that stack flue gas is the main emission way. Daily emission of this path is one or two order magnitudes higher than others and PAHs are mainly composed of low molecular materials.PAHs toxicity changes under different conditions.PAHs toxicity of co-combustion of MSW and coal is higher than that of coal combustion.Combustion with desulfurizer is higher than that of without desulfurizer,but smaller than that of high ratio of MSW.Toxicity increases with increasing ratio of MSW in mixed fuel. |
