| 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%.

| 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. |

| Keywords: | zero valent iron polycyclic aromatic hydrocarbons (PAHs) orthogonal experiment effect factors |
