Research Status and Progress on Treatment of High-salt Wastewater

Different sources, harm and formation mechanisms of high-salt wastewater were introduced. The advantages, disadvantages and application status of physical treatment method, chemical treatment method, biological treatment method and combined treatment process on high-salt wastewater were described. The problem on efficiency and cost still needs to be solved urgently in large-scale treatment of high-salt wastewater. The leading direction of high-salt wastewater treatment in the future is membrane treatment technology. The development of membrane treatment technology still needs to improve from anti-pollution ability and new materials. New technology can improve the following characteristics of the membrane high flux, anti-pollution,oxidation resistance and others by physical modification, biochemical modification and other measures. Actively develop new membrane materials based graphene to improve membrane treatment efficiency and reduce processing costs.
