| Abstract: | With the rapid development of China’s industry, the large-scale combustion of coal carbon leads to a large amount of by-product fly ash accumulation and low utilization rate. At the same time, a large amount of nitrogen-containing wastewater is discharged into lakes, causing serious eutrophication problems. The synthesis of zeolite molecular sieve using fly ash as raw material can improve the problems of large accumulation of fly ash and eutrophication of water body to some extent. In this paper, two hot issues of resource utilization of fly ash and environmental pollution control are studied, and the characteristics and utilization status of fly ash are reviewed, as well as the classification, synthesis methods and influencing factors of zeolite molecular sieve. The application of zeolite molecular sieve in wastewater treatment and the characterization method of ammonia nitrogen adsorption effect were analyzed. The existing problems in this study were put forward and the future development trend was analyzed, in order to provide theoretical basis for the follow-up research. |
