摘　　要：为了对煤化工废水中的固定床气化含酚废水进行处理,研究提出对含酚废水的萃取脱酚流程进行模拟,并对液-液相平衡数据进行分析,最终得出最佳的萃取参数。实验表明,通过分析不同的温度等影响因素下萃取相参数,选取萃取等级为6,萃取相比例为1:3.5的萃取参数,得出总酚剩余的质量浓度为298 mg/L,萃取率为93.05%,单元酚的剩余质量浓度为75.1mg/L,萃取率为83.1%。可见研究基于萃取流程模拟对含酚废水脱酚萃取的有效性,为煤工厂含酚废水处理提供了技术支持。In order to treat phenol containing wastewater from fixed bed gasification in coal chemical wastewater,a study proposes using organic extractants for process simulation,analysis,and ultimately obtaining the optimal extraction parameters.Experiments have shown that by analyzing the extraction phase parameters under different temperature and other influencing factors,selecting extraction grade 6 and extraction phase ratio of 1:3.5,the remaining mass concentration of total phenols is 298 mg/L,with an extraction rate of 93.05%.The remaining mass concentration of unit phenols is 75.1 mg/L,with an extraction rate of 83.1%.It can be seen that the study on the effectiveness of phenol removal and extraction from phenol containing wastewater based on extraction process simulation provides technical support for the treatment of phenol containing wastewater in coal factories.
