摘要
利用粉煤灰吸附性能较好、来源广泛及价格低廉等特点,对染料废水进行吸附试验研究。结果表明,粉煤灰的活化方式、粒度及用量对染料废水吸附性能有影响。160—200目30%硫酸活化粉煤灰吸附能力最强,且对染料废水的吸附过程符合Langmuir吸附等温曲线,最大吸附量为667mg/g。
Using the fly ash which had good adsorption performance, extensive source and lower price, this paper aimed at the dyestuff wastewater treatment. The results of experiments indicated that the flyash which was 160-200 mesh particle and activated by 30% H2SO4 had high absorbability. The adsorption process of the flyash （160- 200 mesh and activated by 30% H2SO4） fited in Langmuir adsorption isothermal line in static test.The maximum adsorption capacity was 667mg/g.
