粉煤灰漂珠在废水处理中的应用

Application of Fly Ash Floating Beads in Wastewater Treatment

粉煤灰漂珠因其特殊的结构和性能,直接用于废水处理效果不理想。但用不同的方法改性后的漂珠,用于废水处理效果显著。本文综述了利用表面化学改性、溶胶-凝胶法等对粉煤灰漂珠进行的改性研究以及其产品用于处理各种工业及生活废水的效果,以期对环境工作者提供参考。

Because of its special structure and performance,fly ash floating beads are not ideal for wastewater treatment directly. However,the modified floating beads by different methods have a remarkable effect on wastewater treatment. In this paper,the modification of fly ash beads by surface chemical modification and sol-gel method is reviewed,and the effects of their products on various industrial and domestic wastewater treatment are reviewed in order to provide reference for environmental workers.
