摘要
研究单独臭氧氧化、O3/H2O2、O3/非均相催化臭氧化技术对去除难降解染料废水CODcr、色度、UV254和提高可生化性的效果。实验结果表明:印染废水最适宜的深度处理方法是O3/MnOx-GAC。当O3投加量为81mg/L时,O3/MnOx-GAC对CODcr、色度和UV254的去除率分别为36.23%、70%和60.67%,B/C由原来的0.1上升到0.26,可采用后续生化处理进一步去除有机物。
A study is made of effect of O3 only,combination of O3/H2O2,O3/heterogeneous catalytic ozonation on removal of CODcr,chroma,UV254,and enhance biodegradability of refractory dyeing wastewater.The results show that,the most feasible advanced treatment of dyeing wastewater is O3/MnOx-GAC technology.When the dosage of ozone was 81mg/L,the removal rate of CODcr,chroma,UV254 reach to 36.23%,70% and 60.67% respectively,the ratio of BOD5 and CODcr increased 0.1 to 0.26.It remove the organics further after the bio-chemical treatment.
