| 中文摘要: |
| 零价铁（ZVI）由于其高效性和经济性已经被应用于水处理中。针对ZVI的研究分为两个方面：一方面是研究ZVI改性，包括粒径、内部结构改变、ZVI与其余金属联用；另一方面则是探究ZVI去除水中不同污染物的机理，包括ZVI本身的还原性，FeOOH的吸附共沉淀性，ZVI促Fenton反应。本文首先介绍了近年来ZVI最新研究进展：a. 海绵铁，b. nZVI，c. ZVI双金属法（微电解法）d. ZVI-Fenton法，e.强氧化剂促ZVI法；接着探究了上述方法去除：（1）重金属，（2）砷，（3）硝酸盐，（4）染料，（5）苯酚的反应机理且发现ZVI对于上述几种污染物有着可观的去除效率；最后对未来ZVI处理废水领域的研究提出了建议 |
| 英文摘要: |
| ZVI (zero-valent iron) has been widely used in wastewater treatment due to its high efficiency and economy. The recent research on ZVI was divided into two major directions. One was to explore the modification of ZVI: including its particle size, internal structure change,and the combination of ZVI and other metals. On the other hand, the mechanism of ZVI removing different contaminants was studied：including the reducibility of ZVI , Adsorption precipitation of the FeOOH, etc. This paper firstly summarized the recent advances of ZVI: a. sponge iron, b. nZVI, c. doping of ZVI with other metals (micro-electrolysis method), d. combination of ZVI with Fenton-based oxidation. Then , the reaction mechanism of ZVI removing pollutants was introduced: (1) heavy metals, (2) arsenic, (3) nitrates, (4) dyes, (5) phenol and it was found that ZVI materials with wide availability have appreciable removal efficiency for several types of pollutants. Finally, the future perspectives regarding the application of ZVI treating wastewater was proposed. |
