Preparation of a New Adsorption Material and its Application in Wastewater Treatment
A kind of new adsorption material for wastewater treatment was made of fly ash as the main composition, with addition of sodium silicate, cement and pore forming material as the accessory materials, etc. Three kinds of practical wastewater were treated by using the new material, they were printing and dyeing wastewater, papermaking wastewater and coking wastewater, respectively. The results showed that removal COD efficiencies of the three kinds of wastewater were 57.89%, 71.43%, 80%, respectively, removal color efficiencies were 90%, 92%, 92%, respectively. The new developed material was mainly used for advanced treatment of the effluent water after biochemical process. It will be a substitute for activated carbon materials and have preferable application prospect.
