纳米铁强化复合新技术对含氯有机污染物的脱氯降解

摘要

Aiming at various restricting factors of nano zero-valent iron (NZVI) for the lower efficiency of treating chlorinated organic pollutants,nano iron enhanced composite new technologies to the dechlorination degradation of chlorinated organic contaminant were introduced,including composite of nano iron and chemical technology,biological technology and composite of nano iron and advanced oxidation technology and so on.The composite technology has high efficiency for the dechlorination of chlorinated organic pollutants.The paper points out that the development direction in the future are:further engineering application of the existing mature technology,the development of efficient and low cost NZVI composite technology,the development and application of NZVI/biological composite technology,etc.%针对纳米铁存在的各种制约因素从而使其处理含氯有机污染物效率降低的问题,介绍了纳米铁强化复合新技术,包括纳米铁与化学技术的复合、纳米铁与生物技术的复合及纳米铁与高级氧化技术的复合技术对含氯有机污染物脱氯降解的进展.分析认为复合技术对含氯有机污染物具有较高的脱氯效率,指出对现有成熟技术进一步工程应用、开发高效低成本的NZVI复合新技术、加强NZVI/生物复合技术的开发与应用等是该技术今后的发展方向.
