煤泥水处理技术研究现状及发展趋势

State-of-the-art and developing trend of coal slurry treatment technology

阐述了黏土矿物、悬浮液中颗粒粒度特性、矿物泥化、煤变质程度和水质特征五因素对煤泥水处理的影响,介绍了当前煤泥水处理技术的研究热点,包括煤泥沉降脱水一体化技术、煤泥水沉降强化技术、煤泥脱水强化技术以及国外煤泥水处理的新思路,同时指出了煤泥水处理过程中存在的几个主要问题,并展望了煤泥水处理技术的发展趋势。

Following an elaboration on the effect on coal slurry treatment produced by five influential factors-presence of clay minerals,size characteristics of solid particles in suspension,degradation of minerals in water,and degree of metamorphism of coal and slurry water characteristics,an introduction is made to the hot points in the research of coal slurry treatment technologies currently made. These include,among others,the settling-dewatering combined technology,intensified sedimentation technology;intensified dewatering technology,and the new ideas in this respect abroad. It points out several major difficulties encountered in the process of coal slurry treatment and the developing trend of this technology.
