水滑石类材料在废水处理方面的应用进展

Application of Hydrotalcite-like Compounds in Water Treatment

简要介绍了水滑石的结构、性质和水滑石类化合物的制备方法,并介绍了水滑石类化合物在印染废水、含磷酸根富营养废水、含卤素元素离子废水、含重金属离子废水及难降解有机物废水处理领域的应用情况。其中,含重金属离子废水处理方面的研究较深入系统,不仅有助于提高含重金属离子废水的资源化处理和回收水平,而且能够降低废水处理成本,在冶金、制革等行业具有较广阔的应用前景。最后,对水滑石类材料的应用现状及发展趋势进行了展望。

The structure,properties and preparation methods of hydrotalcite-like compounds were introduced firstly.Then,introduced the application of hydrotalcite compounds in the field of wastewater treatment,such as printing and dyeing wastewater,phosphates containing eutrophic wastewater,halogen containing wastewater and wastewater containing heavy metal ions and refractory organic wastewater.Of hydrotalcite compounds in the treatment of wastewater containing heavy metal ion research deeply,help to promote the improvement of resource disposal and recycling of metallurgical waste water and waste water treatment cost is reduced,has a broad application prospect.Finally,the application situation and prospects of hydrotalcite class materials is prospected.
