焚烧污泥重金属迁移的研究进展

Research Progress of Heavy Trace Metal Migration During the Incineration of Sludge

焚烧技术是处理污泥的一种常用方法之一,而污泥中的重金属可能对环境造成严重污染。从4个方面对污泥重金属迁移规律进行了国内外文献综述,即:污泥预处理对重金属的削减、污泥焚烧过程中重金属的迁移、焚烧气氛对重金属迁移的影响以及添加剂对焚烧过程中重金属迁移的影响和添加剂对焚烧后的飞灰处理中重金属迁移影响。

The incineration is the main technology to treat sludge, and the emission of heavy trace metal from the incineration of sludge may produce environmental pollution. The research progress of heavy trace metal migration during the incineration of sludge was carried out from four aspects as fellows： pretreatment of sludge, heavy trace metal migration during incineration, incineration condition on the heavy trace metal migration, the additive on the migration of heavy trace metal and the additive on the ash.
