反渗透处理尾矿废水的应用研究

On the Application of Reverse Osmosis Process in Treating Tailings Wastewater

尾矿废水是在矿产资源的开发利用过程中产生的。在我国将反渗透工艺应用于尾矿废水处理领域的工程实例并不多。介绍了反渗透系统工艺流程和主要试验设备,说明了反渗透膜对主要离子的去除效果以及膜的污染等方面问题,为今后将反渗透工艺应用于生产实践提供必要的依据。

Tailing waste water is produced in the exploitation and utilization of mineral resource. Reverse osmosis （RO） process is not much used in the tailing treatmeut in China. The paper introduces the RO process and its main experimental equipment, and makes a detailed description of the removal, effect of the main ions by RO membrane and issues such as membrane fouling, providing a necessary basis for the futare application of RO process in practical production.
