摘　　要：煤泥水净化处理一直是选煤厂生产管理过程中的技术难题。通过无机凝聚剂中阳离子对煤泥颗粒表面双电层的压缩,来实现微细煤泥颗粒凝聚沉降。分析结果表明,阳离子在煤泥颗粒表面吸附形式主要有静电、表面沉淀及羟基络合吸附等方式,讨论了钙、镁、铝等离子的吸附作用机理及其影响因素。Coal slime water treatment has been the key technical problems of production and management in the process of coal preparation plants. By inorganic coagulants in the compression of cationic surface electric double lay- er of slime particles realize fine slime particle coagulation sedimentation is a kind of important settlement of slime water clarification technology. Analysis shows that the adsorption form of cations on the surface of the slime particle have static, surface precipitation and hydroxyl complexation and so on. This paper analyzes the main adsorption form of Calcium, magnesium, aluminum cations in coal slime water and the adsorption mechanism of different metal cations.
