| 摘 要： | 针对A/O生化处理后的焦化废水色度不达标问题,以双氰胺、甲醛为主要原料,合成了双氰胺-甲醛阳离子脱色絮凝剂,对焦化废水进行脱色试验。结果表明,当焦化废水色度为158、pH值为7、絮凝剂投加量为8mL/L时,脱色率可达61.21%。

| Abstract: | To solve the problem of failing to reach the chroma standard of the coking waste water after the biological treatment with A/O process,the dicyandiamide-formaldehyde cation decolorizing flocculant is synthesized with dicyandiamide and formaldehyde as main feedstock.The decolorizing test of coking waste water is carried out.The result shows that when the colority of coking waste water is 158,pH value is 7 and adding amount of flocculant is 8mL/L,the decolorizing rate can be up to 61.21%. |
