摘　　要：为了有效处理化纤厂棉浆黑液,研究了超声-生物法联合处理工艺。通过单因素试验,研究超声时间、样品初始pH值、超声功率对棉浆黑液COD去除的影响,然后在适宜条件下对棉浆黑液进行超声预处理,处理后的黑液利用白腐真菌糙皮侧耳菌株B1降解。结果表明,超声预处理棉浆黑液的最佳条件为:棉浆黑液稀释10倍,频率20 kHz,功率225 W,反应时间120 min。超声-生物法联合处理棉浆黑液与单独采用生物法相比,废水中COD的去除率提高了16%,说明超声作为棉浆黑液的预处理方法可行。Ultrasound-biological process is proposed to effectively treat cotton pulp black liquor in chemical fiber factories.Effects of reacting time,initial pH,power on COD removal are investigated by single-factor experiments.Then ultrasound is studied as a pre-treatment process under the optimal conditions.And white rot fungi are used as a post-treatment.The results show that the optimal conditions are as follows： dilution times 10,frequency 20 kHz,power 225 W,120 min.Treatment efficiency of black liquor by biological is increased after ultrasound pretreatment.A 16% increase of COD removal is achieved.It is indicated that ultrasound pre-treatment is feasible for application in cotton pulp black liquor treatment.
