垃圾焚烧飞灰熔融过程中重金属迁移分布规律的研究

垃圾焚烧飞灰处理中重金属污染一直是倍受关注的问题。采用高温熔融法处理飞,该工艺具有二恶英去除率高、高效减容、有效固化重金属、熔渣可资源化利用等优点。目前学术界针对重金属在熔融过程中的迁移分布规律,研究了温度、碱度、添加剂、气氛、熔融时间等因素对重金属分布的影响。但关于影响程度的量化及影响机制的阐述,仍需要进一步探讨。

Study on the Migration of Heavy Metals in the Melting Process of Fly Ash in Waste Incineration

Much attention were paied to the environmental pollution brought by heavy metals during the process of fly ash treatment of waste incineration.And fly ash melting treatment was proposed to solve this problem.The fly ash melting treatment had advantages in its high removal rate of dioxins,great volume reduction of residue,and effective solidification of heavy metals.At present,studies are focus on the migration rule of heavy metals in the melting process of fly ash.And the influence of temperature,alkalinity...
