摘要
通过正交实验研究了改性粉煤灰吸附处理含油废水的效果。结果表明:改性粉煤灰用量为100g/L、吸附平衡时间100m in、废水pH=10、吸附温度为20℃的条件下,废水中油去除率在96%以上,达到国家含油废水一级排放标准。改性粉煤灰对油的吸附符合Freund lich模型。
An experimental study on treating wastewater containg oil with modified fly ash adsorption is conducted by the orthogonal test method. The results show that the removal rate of oil can reach over 96% under following optimal operating conditions： the dosage of modified fly ash 100g,/L,the contacting time 100min,pH value 10 and the adsorption temperature is 20℃. The content of oil in the treated wastewater reduced from 150 to 5.1 mg/L, which is up to the national firstdegree standards. The adsorption accords with Freundlich adsorption isotherms.
