摘要
Abstract
In this paper,three different types of stabilizers,calcium carbonate,hydroxyapatite,and sepiolite,were used to stabilize heavy metal Pb in sludge,and analyze its stabilization mechanism and effect.The results show that the leaching stability rate of heavy metal Pb in sludge under the stabilization of the three stabilizers is Sepiolite＞CaCO3＞HAP,and the proportion of residual state of Pb after the stabilization of the three stabi-lizers is CaCO3＞HAP＞Sepiolite.In summary,the stabilizing effect of the three stabilizers on heavy metal Pb in descending order is Sepiolite＞CaCO3＞HAP.关键词
