1. But incineration of the electroplating sludge can get remarkable mass decreasing rates as more than 68% for original sludge and more than 30% for exsiccated sludge and high temperature can effectively reduce the lixiviation of heavy metals, but even the lowest lixiviation of Chromium is much higher than the national standard.
焚烧温度、时间和气氛对重金属的析出规律影响各不相同，Ni是唯一没有检测到析出率的重金属，Cr的析出率随着焚烧时间的增加而略有提高，Zn、Cu和Pb的析出率变化规律比较接近，析出率随着温度的增高而增大。
