活性艳蓝印染废水处理技术研究

分别采用紫外线照射(UV)、臭氧(O3)氧化、UV/O3联合法处理活性艳蓝KN-R模拟印染废水,对不同方法的处理效果及影响因素进行研究。结果表明:单纯UV法处理模拟印染废水脱色及COD去除效果甚微;O3氧化处理模拟印染废水,脱色效果明显,COD的去除效果不明显;UV/O3联合法脱色效果明显优于单纯的UV法或O3氧化法,当废水初始浓度为400 mg/L,pH值为12,臭氧空气流量为80 L/h,处理60 min时脱色率高达99.4%,COD去除率为32.0%。

Treatment of Dyeing Wastewater Containing Active Brilliant Blue KN-R

Researched into effects and affection of different treatments,i.e.stimulated dyeing wastewater containing reactive brilliant blue KN-R treated by UV,O3-oxide and process of combined UV/O3 respectively.The effects of operation parameters such as initial dye concentration,catalyst loading,hydrogen peroxide dosage as well as initial pH value were studied.Experiment results showed that the effect of single UV method was not obvious,O3 method had a high effect on decoloration,however,was not that efficient on COD removal rate,the decoloration effect of UV/O3 combined method was obviously better than single UV method or O3 oxidation process,the decoloration rate was 99.4 % and the COD removal rate up to 32.0 % in conditions that the pH of wastewater was 12,the air ozonation flow rate was controlled at 80 L/h and the reaction time was 60 min.
