Experimental Study on Photochemical Oxidation of Organic Micro-pollutants in Aqueous Solutions

通过室内实验研究了溶液浊度、反应器流速对 2 ,4 二氯酚 (2 ,4 DCP)光降解速率的影响 ,确定了光化学氧化降解 2 ,4 DCP反应器的最佳流速和水质适用范围 ,实验表明 ,紫外光解产生活性·OH自由基是有机物降解的直接原因 。

The experimental results in laboratory indicate that hydroxyl radical generated by UV irradiation was the basic reason for results in 2,4-DCP degradation in photochemistry oxidation treatment processes. Some influential factors on 2, 4-DCP degradation were investigated in the study, including turbidity of treated water and flow velocity in the reactor. The experiments have proved that photochemistry oxidation treatment is an effective approach to remove organic micro-pollutants in aqueous solution with a low-tur bidity and optimal flow velocity.
