摘要:

采用零价铁还原修复技术, 对沉积物中16种多环芳烃(PAHs)进行修复, 并通过正交实验考察不同温度、 零价铁的粒径和添加质量对修复效果的影响. 实验结果表明: 当温度为25 ℃, 零价铁的粒径为0.15 mm, 零价铁的添加质量为2 g时, 修复效果最好, 16种PAHs的平均去除率为56.95%.

关键词: 零价铁, 多环芳烃, 正交实验, 影响因素

Abstract:

Zerovalent iron was used to degrade 16 polycyclic aromatic hydrocarbons (PAHs) in sediments. Effects of temperature, particle size of zerovalent iron, zerovalent iron dosage were studied by the orthogonal experiment. The laboratory experimental results show that the average removal efficiency could reach 56.95% at a temperature of 25 ℃, a particle size of zerovalent iron 0.15 mm, and a zerovalent iron dosage of 2 g.

Key words: zerovalent iron, polycyclic aromatic hydrocarbons (PAHs), orthogonal experiment, effect factors
