摘要
采用改性粉煤灰吸附处理含油废水,并研究了改性粉煤灰在不同条件下对含油废水的处理能力。结果表明:改性粉煤灰用量为100 g/L;吸附平衡时间90 min;废水pH10,去除率可达96%以上。改性粉煤灰对油的吸附符合Freundlich模型。
The simulation experiment on the treatment for wastewater containing oil with modified fly ash absorption is conducted by the orthogonal method.The treat capacity to wastewater containing oil is researched by the modified fly ash under different conditions.The result shows that the removal rate of oil can be over 96% with the dosage of modified fly ash 100 g/L;the contacting time 90 min and pH value 10.The absorption accords with Langmuir absorption isotherms.
