在实验室试验装置上，采用不同的水溶性聚合物，对影响细粒煤固液分离过程的多种变量进行了试验研究。结果表明：采用阴、阳离子聚合物配合使用的添加方式，不仅能显著提高细粒煤的固液分离效果，而且还大大降低了水溶性聚合物的用量
In the laboratory test device, different water-soluble polymers were used to study the various variables affecting the solid-liquid separation process of fine coal. The results show that the addition of anionic and cationic polymers not only can significantly improve the solid-liquid separation effect of fine coal, but also greatly reduce the amount of water-soluble polymer
