摘　　要：通过三聚氰酸的次氯酸钠氧化,研究了溶液p H、次氯酸钠投加量、反应温度和反应时间对三聚氰酸溶液TOC去除率的影响,比较了次氯酸钠氧化、芬顿氧化和催化臭氧化的氧化效果。结果表明:次氯酸钠氧化的TOC去除率最高,达84%,总氮质量浓度最低,仅21 mg·L^(-1)。The effect of solution pH, dosage of sodium hypochlorite, reaction temperature and reaction time on the TOC removal rate of cyanuric acid solution was studied in the process of sodium hypochlorite oxidation of cyanuric acid. The oxidation effects of sodium hypochlorite oxidation, Fenton oxidation and catalytic ozonation were compared. The results showed that the TOC removal rate of the solution oxidized by sodium hypochlorite was the highest, reaching 84%, and the total nitrogen mass concentration was the lowest, only 21 mg·L^(-1).
