| 摘 要： | 目的研究改性木质素磺酸盐的合成条件和用改性木质素磺酸盐处理有机物废水的最佳絮凝条件。方法通过正交试验确定絮凝剂的合成条件木质素与单体的质量比、反应时间、催化剂(一种盐和过氧化物的混合物)浓度],通过试验确定改性木质素磺酸盐处理有机物废水的最佳条件(改性)木质素磺酸盐投加量、接触时间、温度]。结果当木质素:单体(质量比)为1:3,催化剂含量为2 mol/L,反应时间为5 h时,可得到絮凝效果较好的改性木质素磺酸盐。在室温下用40 mg/L改性木质素磺酸盐处理100 ml含有机物废水2 h,可使有机物废水的浑浊度、COD_(cr)和UV_(254)的去除率分别达97.4%,74.3%和61.4%以上。结论改性木质素磺酸盐可有效地处理含有机物的废水。
