| 摘要:针对造纸过程中废水难以达标排放的问题，探索了臭氧氧化法的深度处理效果，并采用单因素实验对处理工艺进行了优化。结果表明，以纳米氧化铜作为臭氧氧化催化剂，且臭氧用量为3 g/h，催化剂用量为0.25‰，反应温度30℃，反应时间30 min时，废水CODCr去除率可达95%以上，出水水质满足GB 3544—2008《制浆造纸工业水污染物排放标准》。 |
| Abstract:In order to solve the problem that biochemical effluent from papermaking wastewater could hardly reach the requirement of discharge standard， single factor experiment was used to study the advanced treatment effect by ozone oxidation. The results showed that using nano copper oxide as the catalyst for papermaking wastewater ozonation， when the generation of ozone was 3 g/L， dosage of catalyst was 0.25‰， temperature was 30℃， reaction time was 30 min， the CODCr removal rate of papermaking wastewater was over 95%. Wastewater quality could meet the requirement of GB 3544—2008 Discharge Standard of Water Pollutants for Pulp and Paper Industry. |
