| Abstract: | The process of nanofiltration applied in treating coal mining water with suspended matters was introduced.The effect of nanofiltration membrane operating condition on the premeability of membrane and the application of the combined process in coal mining water treatment were investigated.The results showed that when operated at the cycle of 30 min and washed with air in the opposite direction of feed flow for 3 min,chemistry washes cycle for 5 days,the fouling of the membrane decreased effectively.4 weeks steadily operating datas indicates that the permeate quality of the system is stable and the tested items of the permeate met the national drinking criterion.The nanofiltration membrane is a high-efficiently and economical process in coal mining water treatment. |
