Resource utilization method of 1-aminoanthraquinone production wastewater
The invention discloses a resource utilization method of 1-amino anthraquinone production wastewater, which comprises the following steps: 1, adding the production wastewater, a sulfonating agent, phenol, water and sodium hydroxide into a reaction kettle, dissolving, stirring and uniformly mixing; 2, dropwise adding acetone, carrying out a sulfonation reaction, and starting to dropwise add a formaldehyde solution after the sulfonation reaction is finished; 3, after dropwise adding is completed, performing heat preservation; and 4, after heat preservation is finished, obtaining the concrete water reducing agent or the coal water slurry dispersing agent; and carrying out graft copolymerization on the remaining part after the reaction with acetone, molecules participating in primary polymerization with formaldehyde and sodium lignin to obtain a product containing more and more types of active groups; wherein hydrophilic groups such as sulfo groups, hydroxyl groups and phenolic hydroxyl groups, hydrophobic groups such as anthraquinone, benzene rings and methyl groups and active groups in sodium lignosulphonate act simultaneously, so that the water reducing effect and the dispersing effect are enhanced, and the production cost of the water reducing agent or the dispersing agent is reduced.
本发明公开了一种1‑氨基蒽醌生产废水的资源化利用方法,所述方法包括如下步骤:步骤一,向反应釜中加入所述生产废水、磺化剂、苯酚、水、氢氧化钠,溶解搅拌混合均匀;步骤二,滴加丙酮,进行磺化反应,磺化反应结束后开始滴加甲醛溶液;步骤三,滴加完毕后进行保温;步骤四,保温结束即得混凝土减水剂或者水煤浆分散剂;与丙酮反应后的剩余部分及与甲醛参与初步聚合的分子与木钠一起接枝共聚,得到含有更多数量、更多种类活性基团;其中磺酸基、羟基、酚羟基等亲水基团及蒽醌、苯环、甲基等疏水基以及木钠中的活性基团同时作用,增强了减水效果和分散效果,降低了减水剂或者分散剂的生产成本。
