摘　　要：零价铁以其低毒、廉价、易操作而且对环境不会产生二次污染等优点,而在水污染治理中受到重视。作者介绍了零价铁处理污水的机理并综述了其处理包括重金属废水、偶氮染料废水、氯代有机物废水、硝基芳香族化合物废水、硝酸盐废水等在内各种废水的最新研究进展。指出了零价铁废水处理技术的研究方向,包括对纳米级零价铁的研究、对零价铁去除污染物的机理研究及零价铁与其他技术联用的研究。Zero-valent iron （ZVI） has been paid more and more attention to its application to the wastewater treatment due to its low toxicity, low cost, easy operation and no second pollution producing. The mechanism of wastewater treatment with ZVI is introduced. And the newest research progress in treating various kinds of wastewaters with ZVI is reviewed. These wastewaters include heavy metal wastewater, azo dye wastewater, chloro-organic compound wastewater, nitro-aromatic compounds and nitrate wastewaters, etc. Very good results have been obtained by using ZVI for treating these wastewaters. At the end, further research directions of ZVI are forecast. These research directions include the research on nano scale ZVI, the mechanism of pollutant removal with ZVI and the combined usage of ZVI with other techniques.
