摘要
粉煤灰是一种固体废弃物 ,其比表面积较大 ,常被用作吸附材料而广泛应用于污水的处理 文中参考国内外有关资料 ,综合论述了粉煤灰在污水处理中的应用研究历史和现状 ,包括重金属离子 (Cu2 +、Hg(Ⅱ )、铬离子等 )的去除 ,阴离子 (F- 、PO43- 等 )的去除 ,各种有机污水的处理 ,指出研制高效复合粉煤灰混凝剂是提高粉煤灰利用附加值行之有效的途径之一 ,并分析了当前粉煤灰用于污水处理存在的主要问题 。
Fly ash—one of the solid wastes, is widely used as an absorbent in the sewage treatment because of its certain specific surface area. A discussion is given to the history and status quo of its application study according to relevant literatures from both home and abroad,such as the removal of heavy metal ions (Cu 2+ ,Hg(Ⅱ),Chromium ion et al),anions (F -、PO 4 3- et al) and the sewage treatment of various organic chemical pollutants.It has been pointed out that developing highly efficient and complex fly ash coagulant is one of the effective ways to raise the additional utilization values of fly ash . Not only the main problems on fly ash used in the sewage treatment have been analysed, but also the main development directions have been put forward.
