摘要： 用HCl、H2SO4等试剂对粉煤灰进行改性,制得粉煤灰吸附混凝剂,研究了改性粉煤灰对造纸废水处理的一般规律·结果表明,以φ(HCl)∶φ(H2SO4)=1∶3的混合液为改性剂改性的粉煤灰对造纸废水具有良好的吸附混凝性能,在废水COD浓度为800～1500mg/L,改性粉煤灰用量为25g/100mL,粉煤灰的粒径范围为74～83μm,pH为9～12的实验条件下,COD、BOD、悬浮物、色度的去除率分别可达81 5%、80 7%、99 1%、94%·

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.
