【Abstract】 Effluent of high-salt wastewater in industrial production causes serious environmental pollution, and the use of cation exchange membranes to treat high-salt wastewater is of great significance. In this paper, a new method for preparation of cation exchange membrane was proposed and applied to high-salt wastewater treatment. Firstly, the principle of cation-exchange membrane separation technology was analyzed, and then the preparation of cationexchange membrane was carried out. The water content, swelling degree, ion exchange capacity and mechanical properties of the prepared cation-exchange membrane were tested, and the applicability of the prepared membrane was proved. The application performance of cation-exchange membrane in the treatment of high salt wastewater was verified by experiments. The results show that the method has the advantages of operation simply, high removal efficiency, low secondary pollution and low energy consumption.更多还原
