  • 摘要: 皂素废水中高浓度的SO2-4对环境危害大,厌氧环境下同时投加Fe0和Fe2+生成硫酸盐绿锈增强SO2-4的去除,实验研究了各因素对去除SO2-4的影响。结果表明,降低初始pH能快速提升SO2-4的去除率,25～35 ℃范围内提高温度有利于SO2-4的去除,Fe2+浓度对去除效果影响显著,随着Fe2+浓度的增加,SO2-4去除率快速上升。初始pH为2、温度为25 ℃的条件下,10 g·L-1的Fe0和1 000 mg·L-1的Fe2+能去除93.1%初始浓度为1 000 mg·L-1的SO2-4。XRD和SEM表征结果显示,去除过程中铁粉表面有疏松多孔结构的Fe3O4生成,有利于SO2-4与Fe0接触反应,促进硫酸盐绿锈的生成,进一步增强SO2-4的去除。动力学分析显示,去除过程拟合伪二级动力学模型,吸附SO2-4的过程以单分子层吸附为主。
    Abstract: High concentrations of SO2-4 in saponin wastewater are very harmful to the environment. Under the anaerobic condition, simultaneous addition of Fe0 and Fe2+ enhanced the removal of SO2-4 by generating sulfate green rust. The effects of various factors on the removal of SO2-4 were studied. The results showed that reducing the initial pH quickly improved the removal of SO2-4. In the range of 25 to 35 ℃, higher temperatures favored the removal of SO2-4. Fe2+ concentration had a significant effect on the removal effect. With the increase of Fe2+ concentration, the removal rate of SO2-4 increased rapidly. When the initial pH was 2, the temperature was 25 ℃ and the initial concentration of SO2-4 was 1 000 mg·L-1, Fe0 of 10 g·L-1 and Fe2+ of 1 000 mg·L-1 removed SO2-4 of 93.1%. XRD and SEM results showed that Fe3O4 with loose porous structure was formed on the surface of iron powder during the removal process of SO2-4. It was propitious to the contact reaction of SO2-4 and Fe0, which promoted the formation of sulfate green rust. Thereby, the removal of SO2-4 was furtherly enhanced. The kinetic analysis showed that the removal of SO2-4 was fit to the pseudo second order kinetics model, and the adsorption of SO2-4 was dominated by monolayer adsorption.
