| titleOfInvention | A kind of preparation method of waste liquid of drilling decolorising agent |
| abstract | The present invention relates to a kind of preparation methods of waste liquid of drilling decolorising agent, belong to environmental technology field.The present invention passes through in alkaline solution of sodium hydroxide, fleece material is in isoelectric point or more, carboxyl in wool protein structure is adequately ionized, make to carry more anion groups on fleece material, and then is conducive to cationized gelatin albumen auxiliary agent and is adsorbed onto on fleece material, sodium hydroxide is conducive to the amino on active group and fleece material on cationic dicandiamide-formaldehyde polymer flocculants as catalyst simultaneously, hydroxyl etc. is chemically reacted containing active hydrogen group, and then better cation-modified effect is reached by fleece material, increase the length of linear molecule chain, increase the degree of unfolding of strand in water and reaches modified purpose, improve package flocculability, improve decolorization flocculation effect, when handling waste liquid of drilling, the negative electrical charge in waste liquid coloration molecule can be neutralized and make its unstability, it generates floccule and precipitates separation from water. |
