介绍了ＭＮ－５阳离子絮凝剂的研制理论依据，为解决选煤厂因煤泥水中细泥表面电位高，高灰细泥难以积聚问题，对反复合成试验后研制出的有机复合阳离子絮凝剂进行相互增效和吸附量测定、不同ｐＨ值时电动电位ζ等特性研究，证明了该絮凝剂是一种煤泥絮凝沉降效果很好的高效药剂，在选煤厂煤泥水处理和环境保护中取得了明显的经济效益和环境效益．
In order to solve the problem of high surface potential of fine mud in coal slime water and difficult accumulation of high ash slime in coal preparation plant, the organic complex cation flocculant developed after repeated synthesis test was introduced. Mutual synergism and adsorption capacity determination, zeta potential and other characteristics of different pH value, proved that the flocculant is a slime flocculation and settling effect is very effective and efficient pharmaceutical, obtained in the coal preparation plant slime water treatment and environmental protection The obvious economic and environmental benefits.
