摘　　要：在获取典型危险废物原始电镀污泥的TG、DTG、DTA曲线的基础上,详细地分析了电镀污泥的热特性.对不同终温下的焚烧减重率进行了试验,发现在焚烧温度低于700℃之前已经能很好的除去电镀污泥中的水分、有机质和挥发份.通过管式炉模拟实际焚烧炉工况,研究了不同试验条件对电镀污泥中的重金属浸出特性和迁移特性的影响,结果显示高温可以有效地抑制重金属的浸出特性,但对迁移特性的影响各不相同.The thermal behavior of electroplating sludge, one of typical hazardous wastes, is presented on the basis of its TG,DTG,DTA curves. The weight decreasing rate of original electroplating sludge is studied, and it is found that its moisture and volatile part can be removed before 700℃. The influence of temperature, incineration time and atmosphere on lixiviation and separation of the heavy metals from electroplating sludge were studied, by using tube furnace to simulate the practical incineration conditions. And it shows that the high temperature can effectively reduce lixiviation of heavy metals, but the influences on separation of different heavy metals are various separately.
