The water-quenched slag of Baosteel No. 4 blast furnace was treated by the acid-heat joint modification and then used as simulating the adsorption disposal of nitrobenzene wastewater. The effects factor for adsorption and its isothermal adsorption were studied. The results indicated that under the conditions of diameter of 100 mesh, dosage of 8 g/L, room temperature for reaction time of 60 min to treat the wastewater of 10 mg/L nitrobenzene, and pH value of 7, the removal rate of nitrobenzene reached 81.8%. The isothermal adsorption of removing nitrobenzene by the modified water-quenched slag fits the Langmuir and Freundlich equation mode well. The saturated adsorption capacity is 33. 56 mg/g at room temperature, and the physical adsorption process of nitrobenzene is easily achieved.%取包钢4号高炉水淬渣进行酸热联合改性后用于模拟含硝基苯废水的吸附处理,研究了吸附的影响因素及等温吸附行为.结果表明:在室温、自然pH、模拟废水硝基苯质量浓度为10 mg/L、改性水淬渣粒度和用量分别为-100目和8g/L、吸附时间为60 min条件下,硝基苯的去除率可达81.8％；改性水淬渣对硝基苯的等温吸附行为较好地符合Langmuir和Freundlich模式,室温下饱和吸附容量为33.56 mg/g,吸附过程较易进行.
