| Abstract: | Based on the physical and chemical properties of coal fly ash,the study comprehensively described the research and application of coal fly ash in soil amendment and pollution treatment at home and abroad.As soil amendment,coal fly ash can decrease the soil bulk density affectively and adjust the soil pH and increase the heat insulation capacity of soil,meanwhile it may also improve the nutrients of the soil and affect the soil microbial biomass greatly.In pollution control,coal fly ash mainly used in wastewater treatment,heavy metal passivation and waste gas purification.At last,the existing problems of research and application of coal fly ash in soil amendment and pollution treatment and their countermeasures were put forward. |
