研究了O_3/H_2O_2体系催化氧化处理抗生素废水的效果。对比了O_3/H_2O_2与O_3氧化体系对抗生素废水的处理效果,并考察和优化了反应时间、初始pH、H_2O_2投加量及O_3气体流量等因素的影响。结果表明:O_3/H_2O_2体系氧化抗生素废水的最佳运行参数为反应时间40 min、初始pH9.0、H_2O_2投加量60mg/L、O_3流量450mL/min。在最佳实验条件下,COD由102.0mg/L降低至32.5mg/L,去除率为68.1%,废水色度及浊度的去除率分别为98.8%、42.3%,综合处理效果优于O_3氧化技术。
The effect of O_3 / H_2O_2 system on catalytic oxidation of antibiotic wastewater was studied. The effect of O_3 / H_2O_2 and O_3 oxidation on the treatment of antibiotic wastewater was compared and the effects of reaction time, initial pH, H_2O_2 dosage and O_3 gas flow rate were investigated. The results showed that the optimum operating parameters of O3 / H2O2 wastewater were reaction time 40 min, initial pH 9.0, H 2 O 2 dosage 60 mg / L and O 3 flow rate 450 mL / min. Under the optimum experimental conditions, COD removal from 102.0mg / L to 32.5mg / L, removal efficiency of 68.1%, removal of chromogenic and turbidity of wastewater were 98.8% and 42.3%, respectively, and the comprehensive treatment effect was better than that of O_3 oxidation technology.
