摘　　要：采用X射线衍射和筛分试验对某选煤厂高泥化煤泥水进行了性质分析,研究了煤泥水浓度、药剂用量和水质对煤泥水絮凝沉降的影响。结果表明:试验用煤泥水中含有大量的粘土类矿物,这些矿物极易泥化是形成高泥化煤泥水的原因;煤泥水浓度和絮凝剂用量为絮凝沉降的主要影响因素;絮凝剂用量有最佳值,在不同煤泥水浓度下寻找最佳药剂量;某选煤厂源水与自来水相比,利于沉降。The properties of extremely sliming coal slime water from one coal preparation plant were analyzed through X-ray diffraction and screening experiment, while the effect of the concentration of slime water, the dosage of agent, and the water quality on the settlement were also studied . The results show that a large number of clay minerals are in the sample which make slurry water into extremely sliming coal slime water; the concentration of slime water and the dosage of agent are the main factors in settlement ; the optimum dosage of agent should be found by experiments as the concentrations of coal slurry is different ; compared with running water , the water in the plant is advantageous to the settlement.
