摘　　要：针对氧碱蒸煮造纸黑液pH近中性、COD浓度较低、产生量较少的特点,采用酸析木素法对其进行处理。考察了絮凝剂种类、投量以及pH、反应温度和时间等对处理效果的影响,并得到了最佳工艺条件。According to the characteristics of oxygen-alkali cooking black liquor from papermaking, such as near neutral, low COD concentration, and less production, the acid extracting lignin process was used for treatment of the liquor. The influence of the factors including the kind and dosage of flocculant, pH, and reaction temperature and time on the treatment efficiency was investigated, and the optimal operational conditions were obtained.
