气浮法实现选煤厂煤泥水闭路循环的试验研究

笔者对气浮法和沉淀法处理煤泥水作循环用水的效果进行了比较。从试验所得的数据来看 ,用气浮法处理煤泥水作循环用水的方法是可行的 ,气浮法在回收煤泥方面要明显优于沉淀法 ,特别是当煤泥水浓度较高或较低时 ;但如果煤泥水要达标排放 ,则还需进一步处理 An effect comparison between air flotation and sediment method for slime water closed circle use was conducted. The result is shown that, the air flotation method is bettr obviously than sediment method in slime recovery especially when the concentration of slime water more higher or lower. However, the slime water can not accord with the discharge standard. If to do so, it should be further treatment
