摘要：

Zeolite from coal fly ash is hydrothermal synthesis by microwave-assisted, and it is used to process wastewater. Through the XRD analysis, we discovered that many kinds of zeolites were synthesized in the experiment. The influence factor of zeolite sythesis is chemical composition, activator, temperature, time,etc. This kind of zeolite is used in processing wastewater, removed some positive ions from wastewater, like NH4+,Cu2+,Fe2+,Mn2+,and so on. Meanwhile some PO43+ and CODCr were removed. The main principle of zeolite processing wastewater is cation exchanging. There are physical-chemistry adsorption and the chemical precipitation in this process.
