造纸污泥焚烧灰中重金属含量及其浸出特性

The Content and Leaching Characteristics of Heavy Metals in Sludge Incineration Ash

研究了不同振荡时间和pH条件下,造纸污泥焚烧灰中9种金属离子Fe、Pb、Cu、N i、Zn、Mn、Cr、Cd、Ca的浸出量及特征。结果表明:在不同pH或是不同振荡时间,Cr的浸出含量都最高。

This experiment mainly tests rate the duration of oscillation and the pH influence factor.Surveys separately burns in the incineration 9 metallic ion leaching quantity and the characteristic.Aims at each kind of leaching metallic ion the leaching characteristic to make the corresponding processing measure.By the experiment knew regardless of is in different pH perhaps the different duration of oscillation,the Cr leaching content all is highest.
