由于特殊的结构与性能,纳米材料在各个领域被广泛使用.纳米材料的环境行为、生物和生态效应受到了极大关注.另外,一些工业生产实践中也产生纳米污染物.然而,关于如何控制和治理纳米污染物的研究较少.在前期的研究中,通过控制纳米颗粒快速长大以消除纳米污染物环境危害的思路被提出,并应用于处理氯酸盐行业的含Cr(Ⅵ)纳米废渣.在此基础上,本文进一步分析和对比了含Cr(Ⅵ)纳米废渣的高温和室温两种处理途径的相关物相变化特征和无害化机制,选择高温处理工艺路线进行了优化,并进一步对无害化处理后固体粉末的物相、形貌、粒度、热性能等性质进行了研究,将其试用于陶瓷釉料.该工作是纳米技术用于环保污染治理与资源化利用的一个范例,具有理论意义和实践价值.
Due to the special structure and properties of nanomaterials, nanomaterials are widely used in various fields, and environmental behavior, biological and ecological effects of nanomaterials have received great attention.In addition, some industrial production practices also produce nano-pollutants.However, on how to control And less research on the control of nano-pollutants.In the previous research, the idea of controlling the rapid growth of nano-particles to eliminate the environmental hazards of nano-pollutants was proposed and applied to the treatment of chlorate containing Cr (Ⅵ) On the basis of this, we further analyzed and compared the phase change characteristics and harmless mechanisms of Cr (Ⅵ) nanosized wastewaters at high temperature and room temperature, and optimized the process route of high temperature treatment Further study on the phase, morphology, particle size, thermal properties and other properties of the solid powder after innocuous treatment, try it on ceramic glaze. This work is a nano-technology for environmental pollution control and resource utilization Examples, with theoretical and practical value.
