| 摘 要： | 采用O_3-H_2O_2-催化剂氧化体系对某石化企业含盐废水的二级生化出水进行处理,考察了不同反应体系下的反应时间、O_3流量、H_2O_2投加量对COD去除效果的影响。实验结果表明:O_3-H_2O_2-催化剂氧化体系对石化含盐废水的处理效果最好;在臭氧流量为40 m L/min、H_2O_2投加量为50 mg/L、催化剂投加量为300 g/L、反应时间为60 min的条件下,COD去除率为51.4%,出水COD为52.0 mg/L,达到GB31570—2015《石油炼制工业污染物排放标准》的要求。

| Abstract: | The bio-treatment effluent of salt-containing wastewater in a petrochemical plant was treated in a O3-H2O2- catalyst oxidation system. The effects of reaction time,O3 flow and H2O2 amount on COD removal were studied in different reaction systems. The experimental results showed that：The treatment effect of the O3-H2O2- catalyst oxidation system was the best;Under the conditions of O3 flow 40 mL/min,H2O2 amount 50 mg/L, catalyst amount 300 g/L and reaction time 60 min,the COD removal rate was 51.4%,the COD of the effluent was 52 mg/L,which met the national discharge standard of GB31570-2015. |
