摘要
改性粉煤灰与原始粉煤灰相比,其物理化学性质发生显著改变,不仅具有吸附能力强、对废水处理效果好和可去除污染物范围广等优点,而且灰水分离能力强、处理污泥数量少,废水处理经济性大大提高。毋容置疑,改性粉煤灰是粉煤灰在工业水处理中应用的必然趋势。作者对改性粉煤灰技术在工业水处理中的应用做了概述,着重阐述了改性粉煤灰的一些工程实际应用及其现状,并提出改性粉煤灰在处理工业废水中一些亟待解决的问题、研究方向和应用前景。
Compared to raw fly ash,physical and chemical characteristics of modified fly ash have changed dramatically after the modification process. Therefore, adsorption capacity and removal property have been better outstandingly, and what is more, much less resulting sludge which can be separated and tackled more easily from treated clean water, has been produced. Modified fly ash is bound to be utilized more extensively to purify wastewater on a larger scale without any doubt. A general description of present utilization fields of modified fly ash in industrial wastewater treatment has been made based on lectures published in China and abroad, and the present application state of modified fly ash is introduced. At the same time, some urgent and imperative problems, research directions and some discussions about its future application are put forward too, in the field of industrial wastewater treatment.
