Modification of Fly Ash and its Application State Research in Wastewater Treatment

Abstract:

Coal fly ashes are a coal combustion product at high temperature. With a certain porous structure and large specific surface area, they have certain adsorption capacities and can be used as the materials for watewater treatment.But limited by the adsorption properties, the raw coal fly ashes have a very low pollutant removal efficiency, and can not meet the practical requirements of wastewater treatment. Therefore, researches now focus on the coal coal fly ashes modification, including increasing the active components in them, enlarging the specific surface area to improve their performance, and to enhance their wastewater treatment effects.Aiming at providing some references of their integrated utilization in wastewater treatment, the modification methods and application status of the coal coal fly ashes are summarized.
