摘　　要：根据水质特点和现有的实验条件,以氯离子、硫酸根的去除为主要目标,测定出循环冷却排污水指标,采用活性炭、大孔离子交换树脂、掺氮纳米二氧化钛等技术进行处理。结果表明,在活性炭的最佳条件下处理,氯离子的去除效率为47.40%,再用离子交换树脂处理,硫酸根的去除效率可达63.40%;氮掺杂二氧化钛比纯的二氧化钛处理效果好,调节水样pH值为4,当掺氮纳米TiO2投加量为2.00 g/L,在11W的台灯照射下慢搅拌30 min,氯离子的去除效率可达37.56%,从实验中还了解到紫外光对氯离子的去除效果比其他光源好。According to the characteristics of water quality and existing experimental conditions, this experiment determine the index of circulating cooling water with the technologies of activated carbon, macroporous ion exchange resin, Nitrogen-doped nanometer TiO2 and so on, aiming to removing the chloride ion and sulfate. It is conclude that the removal efficiency of chloride ions is 47.40% at the optimal conditions of the activated carbon and the removal efficiency of sulfate can reach 63.40% using the technology of reoccupy ion exchange resin; It can get better effect with Nitrogen-doped nanometer TiO2 than pure TiO2. Adjusting the pH value of water sample for 4, stirring slowly for 30 minutes under the irradiation of the lamp in the 11W when the dosing quantity of Nitrogen-doped nanometer TiO2 is 2. 00g/L, the removal efficiency of chloride ions can reach 37. 56%. It also can be known that the removal effect of chloride ion is better using UV light than others from this experiment.
