| 摘 要： | 采用UV+H2O2和UV+H2O2+Fe2+二种高级化学氧化工艺处理硫酸盐苇浆CEH漂白废水,研究了氧化剂用量、Fe2+浓度、初始pH值、处理时间等因素与处理效果(以COD和色度为指标)的关系.研究表明,添加Fe2+可大大加速体系对有机污染物氧化降解,H2O2用量对COD和色度的去除影响显著,硫酸盐苇浆CEH漂白混合废水pH值呈较强的酸性,适合于采用UV+H2O2+Fe2+工艺氧化处理.

| Abstract: | Two kinds of advanced chemical oxidation processes were used for the treatment of CEH bleach effluent of reed kraft pulp in this study. The relationship between the influencing fac- tors (such as H2O2 dosage,Fe2 + concentration, pH value and treatment time) and COD and color removals were investigated. The experimental results indicated that the dosage of H2O2 had the most remarkable in fluence on COD and color removals among the several factors studied in this paper. Fe2+ can accelerate the decomposition of organic pollutants. The effluent from CEH bleach process of reed kraft pulp was very susceptible to the chemical oxidation treatment process of UV + H2O2 + Fe2 +. |
