膜分离技术在矿井废水回用中的应用

Application of film separating technique to mine wastewater reuse

针对大同某煤矿用水困难,矿井废水铁锰含量高,采用微孔曝气、锰砂过滤、超滤、反渗透相结合的处理工艺解决矿区工业生产和居民生活用水。从而推动了膜分离技术在中水回用方面的应用。

According to the problem of using water in mines, it is known that the contents of iron and manganese in coal mines are high. The treatment technologies, such as millipore aeration, manganese filtration, ultrafiltration and reverse osmosis are used in combination, to solve the water proplems in industrial production and domestic use. The application of film separating technique to the reuse of treated water in mine areas can therefore be promoted.
