新型废水絮凝剂的研究

On a New Focculant for Wastewater

以苯胺和甲醛为原料,在酸性条件下,采用简单工艺合成一种阳离子絮凝剂F。用此絮凝剂处理染料废水和造纸黑液效果显著,脱色率和COD去除率都在96%和76%以上。

Synthesizes a cationic flocculant using simple technology in the presence of acidic catalysts with aniline and formaldehyde as starting materials. The treatment result is very good when dyeing wastewaters and black liquid of paper are treated with this flocculant, the removal efficiency of colority and COD are beyond 96% and 76% .
