Abstract：

This paper introduced the process of nanofiltration for treating mining water containing suspended matters.The influence of nanofiltration membrane operating condition to the filtration function of membrane and the effect of the combined process on coal mining water treatment were investigated.The experimental results showed that when operated at the cycle of T=30min and adapted to backaeration,the fouling of the membrane decreased effectively.The effluent quality of the system is stable and the tested items of the effluent met the national drinking criterion.The nanofiltration membrane is a high-efficiency and economical process in coal mining water treatment.

Key Words： nanofiltration membrane;membrane function;coal mining water.
