废水中重金属离子去除技术的研究及进展

Research and progress in the technique of heavy metal ions removal from waste water

伴随着工业技术的飞速发展,各种各样的污染物被排放到环境中。其中,重金属因具有富集性而几乎不能发生降解,对环境和人体造成巨大的危害。通过描述国内外应用于废水中重金属离子脱除的相关方法及各类方法的研究现状,以各种脱除方法为框架给出了相应的、有代表性的理论结果。通过描述各类方法的优缺点,介绍了具有巨大发展前景的新型水处理吸附材料,对其在重金属离子脱除领域的相关进展进行总结。

With the rapid development of industrial technology,various pollutants are discharged into the environment.Among them,heavy metals can hardly be degraded due to their richness,which causes great harm to the environment and human body.The relevant domestic and international research methods for removing heavy metal ions from waste water are described,and the corresponding classical theoretical results based on various removal methods are proposed.By describing the advantages and disadvantages of various methods,a new type of water treatment adsorption material with great development prospects is introduced,and its related progress in heavy metal ion removal is summarized.
