二氧化氯—活性炭组合催化氧化刚果红废水

Catalytic Oxidation of Congo Red with Chlorine Dioxide and Activated Carbon

采用自制的液体二氧化氯催化氧化刚果红废水,并研究二氧化氯-活性炭组合对处理效果的影响.确定了pH值,温度及二氧化氯投放量等工艺条件.前期二氧化氯处理,刚果红的去除率为44.61%,后期用活性炭进一步吸附,使刚果红的去除率明显提高,达到80%以上.

Based on the study of possibility of Congo red treatment using the combination of chorine dioxide and activated carbon,the relevant optimal factors for removing rate,such as pH value,temperature and dosage of oxidant were determined.The removing rate of Congo red reach about 44.6% pretreated with chlorine dioxide,and reach about 80% followed treated with activated carbon for absorption.
