摘　　要：分别用碱、酸、高温、超声波和助溶剂对粉煤灰进行改性,对每种改性粉煤灰吸附处理含铜废水进行研究。试验结果表明:其中碱、高温、助熔剂都可改性粉煤灰,碳酸钠助熔剂改性效果最好,其最佳反应时间是30min,最适宜反应温度是20℃,最适宜p H值是10。吸附过程符合Temkin和Langmuir吸附等温式。Fly ash was modified by Sodium hydroxide,Sulfuric acid,high temperature,ultrasonic and Sodium carbonate co- solvent. It＇s investigated adsorption characteristics and the optimal adsorption conditions of Copper- containing wastewater by modified fly ash. Results show that fly ash can be modified by the sodium hydroxide,high temperature and solvent. Sodium carbonate co- solvent is the best. The experimental results show that： the optimum reaction time is 30 minutes,the most appropriate reaction temperature is 20 ℃,the optimum p H value is 10. The adsorption process of Copper- containing wastewater on alkali- modified fly ash accords with Temkin and langmuir isotherm equations.
