| Abstract: | In recent years, fly ash is often used as a raw material for synthetic zeolite due to its low price, high output and similar structure to zeolite. In terms of water treatment, the research on the treatment of nitrogen and phosphorus wastewater with fly ash-based zeolite is quite popular among scholars. The physical and chemical properties and utilization status of fly ash are introduced. Ion exchange, adsorption and catalysis are the main characteristics of fly ash-based zeolite, due to its unique internal structure. The mechanism of nitrogen and phosphorus removal by fly ash-based zeolite is introduced. The focus is on the progress of the treatment of low, medium and high concentrations of ammonia nitrogen wastewater, phosphorus wastewater and nitrogen-phosphorus coexisting wastewater with fly ash-based zeolite. Finally, the current problems in this field and future development trends are analyzed. |
