摘　　要：海泡石是一种纤维状含水的镁硅酸盐矿石 ,具有良好的吸附性能。纺织印染废水的组分异常复杂 ,是较难处理的废水之一。利用江西乐平产的海泡石对纺织印染废水进行了试验研究 ,实验结果表明 ,脱色率 >90 % ,CODCr去除率为70 %— 80 % ,其吸附容量为 30 7%。Sepiolite is a fibrous natural hydrated magnesium silicate with good absorptive property. The printing and dyeing wastewater with extreordinary complicated components is one of the wastewater difficult to be treated. Application of sepiolite to the treatment of printing and dyeing wastewater was presented in this paper. The results showed that sepiolite absorbent has a colou removal rate of more than 90% and a COD Cr removal rate of 70%-80%. The adsorptive capacity reached 30.7%.
