Abstract:

Some information of fly ash,such as its source,quantity,hazards,the main components and properties are introduced. The preparation of various polysilicate coagulants using fly ash as main raw material is reviewed. Preparation methods,category,situation of research and result of utilization are also introduced. The reaction mechanisms of preparing coagulants for wastewater treatment are analyzed. Problems existing in the preparation of polysilicate flocculants from fly ash are summarized. Suggestions on how to exploit and make use of fly ash more efficiently are brought forward.

Key words: fly ash, polysilicate, coagulant, wastewater treatment
