Abstract:

With ilmenite slag as raw material，the inorganic high polymer flocculant has been prepared by orthogonal test. It shows that optimum synthesis conditions are as follows：the pH of pickle liquor is 2.2，reaction temperature45 ℃，and polymerization time 2 h. The treatment effectiveness of the prepared flocculant on printing and dyeing wastewater is discussed，and its structure and morphology characteristics are analyzed by FT -IR and SEM. The research shows that spherical polyferric flocculant with doped structure and amorphous structure has good effects on flocculating sedimentation.

Key words: ilmenite slag, flocculant, printing and dyeing wastewater

摘要：

以钛铁矿废渣为原料,采用正交实验设计,制备了无机高分子絮凝剂。实验表明最佳合成条件为:酸浸液pH为2.2,反应温度为45℃,聚合时间为2 h。探讨了所制絮凝剂对印染废水的处理效果,并借助FT-IR、SEM分析了产品的结构和形貌特征。表明球形、具有掺杂结构、无定型态的聚铁絮凝剂具有良好的絮凝沉积效果。
