摘要
研究单独臭氧氧化和过氧化氢/臭氧联合作用对去除难降解染料废水CODcr、色度,提高可生化性的效果,并考察不同pH值、不同初始污染物浓度、H2O2投加量等对染料废水活性艳红X-3B处理效果的影响。实验结果表明:臭氧氧化对CODcr去除率达到50.00%,对色度的去除率接近100%,B/C由原水的0.0 507上升到0.2 768;废水在pH值为11时处理效果最好;而过氧化氢/臭氧联合作用的最佳摩尔比为0.6。
A study is made of effect of O3 only and combination of H2O2/O3 on removal of CODcr,chroma,and enhance biodegradability of refractory dyeing wastewater.The influential factors on reactive brilliant red X-3B,such as different pH values,different organics concentration,the dosage of H2O2 and so on,have been discussed.The results show that,the removal rate of CODcr reaches 50.00%,the removal rate of chroma is closed to 100%,and ratio of B/C rises 0.0 507 to 0.2 768.It is indicated the most appropriate pH values of the dyeing wastewater is 11,and the feat molar ratio of H2O2/O3 is 0.6.
