摘要
针对臭氧处理工艺及其处理条件在降解酸性红GR和活性红X-3B印染废水时选择困难的问题,采用单独臭氧、臭氧耦合微电解、臭氧耦合双氧水、臭氧耦合紫外、臭氧耦合超声及金属催化臭氧氧化处理等6种技术对酸性红GR和活性红X-3B印染废水进行对比处理。结果表明:处理酸性红GR印染废水时,单独臭氧处理的去除效果最佳,处理30 min后色度去除率可达99.99%,处理90 min后COD去除率可达69.41%;处理活性红X-3B印染废水时,臭氧耦合紫外氧化处理的去除效果最好,处理30 min后色度去除率可达99.23%,处理90 min后COD去除率可达32.83%。臭氧高级氧化技术可有效降解酸性红GR和活性红X-3B印染废水,并且通过改变工艺的处理条件可明显提高酸性红GR和活性红X-3B印染废水色度和COD的去除率。
In view of the difficult selection of ozone treatment process and treatment conditions in the degradation of acid red GR and reactive red X-3B dye wastewater,six different treatment methods were used to treat the wastewater in the experiment,including ozone treatment alone,ozone-coupled micro-electrolysis,ozone-coupled hydrogen peroxide,ozone-coupled ultraviolet(UV),ozone-coupled ultrasonic,metal-catalytic ozone-oxidation treatment.The treatment conditions of the six processes were optimized and the treatment effects of the six processes were compared.The results show that when treating acid red GR dye wastewater,ozone treatment alone has the best removal effect.The chroma removal rate can reach 99.99%after 30min treatment,and the COD removal rate can reach 69.41%after 90 min treatment.When treating reactive red X-3B dye wastewater,ozone-coupled UV oxygen treatment has the best removal effect.The chroma removal rate can reach 99.23%after 30 min treatment,and the COD removal rate can reach 32.83%after 90 min treatment.Ozone advanced oxidation technology can effectively degrade acid red GR and reactive red X-3B dye wastewater,and the chroma removal rate and COD removal rate of the wastewater can be significantly improved by changing the treatment conditions of the process.
