UV/H_2O_2降解水中2,4-二氯酚实验研究

Pilot-scale Study on Degradation of 2, 4-Dichlorophenol in Aqueous Solution by UV/H_2O_2

研究溶液浊度、pH值及不同光源等因素对 2 ,4 二氯酚降解的影响 ,确定了UV/H2 O2 光氧化降解 2 ,4 二氯酚反应器的水质适用范围 (浊度小于 6NTU)。在 30W的紫外光照射下 ,2 0mg/L 2 ,4 二氯酚 ,H2 O2 的投加剂量为 1 .2 8mg/L时 ,90min内 2 ,4 二氯酚去除率可达到 95 % .实验证明UV/H2 O2 光氧化技术是低浊度水深度处理的一种有效方法 .

The impact of turbidity, light source, pH value on degradation of 2, 4-dichlorophenol (2, 4-DCP) was analyzed to determine water quality limit with turbidity of aqueous solution less than 6NTU by UV/H_2O_2 photochemistry oxidation degradation. The removal rate of 20 mg/L 2, 4-DCP can be up to 95% in 90min by adding H_2O_2 dose 1.28 mg/L under UV power 30 W. UV/H_2O_2 photochemistry oxidation treatment was proved to be an effective approach to remove organic micro-pollutants in aqueous solution with low turbidity.
