| 摘 要： | 采用臭氧-活性炭技术对炼化企业RO浓水进行实验研究。通过研究该废水在不同pH、臭氧投加量、臭氧接触时间、投加催化剂、活性碳吸附时间和活性碳投加量条件下RO浓水中COD的去除效果,确定臭氧-活性炭工艺处理炼化企业RO浓水的工艺参数。结果表明:在pH为8,臭氧投加量为75 mg/L,臭氧接触时间为5 min,催化剂KMnO4的投加量为35 mg,活性炭吸附时间为150 min,活性炭投加量为4 g/L时,臭氧-活性炭技术对RO浓水中COD处理效果达到最佳,总去除率为58%。

| Abstract: | The ozone activated carbon technology was used to treat the RO brine from a refining & chemical company.By studying the removal effect of COD of the wastewater under different pH,ozone dosage,ozone contact time,catalyst dosage and dosage of activated carbon,the process parameters of the ozone-activated carbon technology which is used to treat the RO wastewater produced from the refining & chemical company were known.The results showed that the removal rate of COD of the RO brine treated by the ozone-activated carbon technology was 58% when the pH was 8,the ozone dosage was 75 mg/L,ozone contact time was 5 min,potassium permanganate dosage was 35 mg,activated carbon contact time was 150 min,activated carbon dosage was 4 g/L. |
