摘　　要：利用基于pH值静态方式的消溶实验系统对碱性工业废渣如白泥、电石渣、碱渣、盐泥等进行消溶特性研究。结果表明:pH值对碱性工业废渣消溶影响较大,随着pH值减小,消溶率增大;粒径对消溶率的影响最大,粒径越小消溶率越大,最佳粒径范围为0～0.097 mm;在反应温度30、40、50℃下进行的实验表明,温度对碱性工业废渣消溶特性影响较小。消溶特性研究表明,4种碱性工业废渣最终消溶率由大到小依次为:电石渣>白泥>碱渣>盐泥。The dissolution characteristics of alkaline industrial wastes such as white sludge,carbide slag,alkali slag and salt slag from different sources were studied by pH-stat method in various parameters.The results show that the lower the pH value is,the higher the dissolution rate is;particle size is the direct function of dissolution rate,the smaller the size is,the higher the dissolution rate is,the optimal particle size is 0～0.097 mm;the reaction temperature has slightly influence on alkaline wastes dissolution.The experiments show that the final dissolution rate of the alkaline wastes in the descending order are carbide slag,white sludge,alkali slag,and salt slag.
