通过对不同掺量比例的电镀污泥和生活污泥砂浆试样的重金属浸出试验，研究了水泥固化作用对污泥中重金属浸出的影响。研究结果表明，重金属浸出浓度随着污泥掺量比例的提高而增大；不考虑物理稀释作用，同种类污泥的砂浆试样的重金属浸出浓度比较接近；随着养护龄期的延长，重金属浸出浓度呈降低趋势。

The effect of the cement solidification on the leaching of heavy metals in the sludge was studied by the leaching experiment of the heavy metals in the different proportions of electroplating sludge and sewage sludge mortar specimen.The results show that the leaching concentration of heavy metals increase with the proportion of sludge.Ig-noring with the effect of physical dilution,the leaching concentration of heavy metals of the same kind of sludge mortar specimen have no significant difference.The leaching concentration of heavy metals decrease with curing time.
