Removal of Chloride Ion in High Salt Wastewater by Ru-Ti-AC Composite Catalytic Materials
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%。
Abstract: 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.
