Abstract: The ability of fly ash to treat papermaking wastewater was investigated. The results show that fly ash modified by the modification reagent of HC1:H2SO4=1:3 is effective to adsorb environmental harmful elements and substance in papermaking wastewater. When concentration of ODD is 800-1500 mg/L and pH 9-12 in the wastewater, 25 g modifying fly ash with particle size of 74-83 μm mesh can remove the COD, BOD, suspended solids and chrominance by 81.5%, 80.7%, 99.1% and 94% respectively.
