摘要
对经微电解预处理后的酸性大红染料配制废水进行二氧化氯催化氧化实验,结果表明:当废水COD=3400mg/L左右,pH=4,氧化反应时间为45分钟,ClO2投加量为750mg/L,在催化剂作用下,COD平均去除率达到88%左右,而单一的ClO2氧化,其COD平均去除率仅为28%左右。
A study of chlorine dioxide catalysis and oxidation experiments on the wastewater of Acid Brilliant Scarlet dye being pre-treated by micro-electrolysis showed that at the optimized conditions, i.e. chemical oxygen demand(COD) 3400mg/L, pH 4, reaction time 45min., amt. of chlorine dioxide 750mg/L, the average COD efficiency was only 28% against 88% if the catalyst being added.
