摘要 采用碱性氧化焙烧工艺回收含铬污泥中的铬,以浸出渣作为焙烧填料,最佳工艺条件为:含铬污泥加入量10 g,浸出渣加入量8 g,焙烧温度700℃,焙烧时间40 min,n(Cr_2O_3):n(NaNO_3):n(Na_2CO_3):n(NaOH)=1:2:3.5:10。在此条件下,碱性氧化焙烧工艺铬浸出率高达98%以上。 Chromium was recovered from chromium-containing sludge by alkaline oxidizing roasting process using leaching residues as baking filler. The optimum conditions are as follows: chromiumcontaining sludge dosage 10 g, leaching residue dosage 8 g, roasting temperature 700 ℃, roasting time 40min, n(Cr2O3) : n(NaNO3) : n(Na2CO3) : n(NaOH) = 1: 2 : 3.5 : 10. Under these conditions, the leaching rate of chromium is above 98 %.
