摘　　要：高浓度氯离子废水处理是目前水处理领域的难点,为克服难点设计了一种电催化去除氯离子的Ru-Ti-AC催化材料,并制备成钌钛活性炭篮式复合电极,通过电化学方法对废水中氯离子进行降解。同时通过单因素实验法和连续实验法,确定了PH为2~8,电解时间为60 min,氯离子浓度为12,000 mg/L的条件下,本实验制备的钌钛活性炭复合电极(Ru-Ti-AC)对氯离子废水中氯离子去除率可达到80%,同时这种方法对实际脱硫废水中的氯离子废水也有很强的去除能力,工业化实际氯离子去除率可达75%。Treatment of high chloride wastewater is difficult. To overcome this difficulty, a kind of material is designed containing Ru, Ti and activated carbon to remove chloride, and Ru-Ti-AC composite basket electrode is manufactured, through electrochemical method to remove chlorine in wastewater. Cl? removal efficiency of catalytic basket electrode in different factors and an in-depth research of Cl? removal mechanism were studied. The experiments were carried out under the conditions of initial pH of 2, reaction time of 60 min, electric current density of 400 mA, Cl? concentration of 12,000 mg/L. The experimental result showed that removal of Cl? could reach 80% in the laboratory. The composite basket electrode also had a good treatment effect on actual high chloride wastewater, and the removal rate of Cl? could reach 75% in the industrialized treatment of desulfurization waste water.
