Abstract:

Several problems of coagulant in the treatment of wastewater from print ing and dyeing are discussed the mechanism,advantage and disadvantage of all sorts of coagulants,special characters of each coagulant and the interaction relationship of different coagulants,and the relationship of the dyeing molecular structure,dyeing state and coagulation effect.Then the complex principle of coagulants is concluded.

Key words: wastewater of printing and dyeing, coagulation, complex coagulant

摘要:

对各种混凝剂的混凝机理与优缺点进行了分析,讨论了特定的混凝剂在印染废水处理中的特性及不同混凝剂之间的相互作用关系,论述了染料分子结构与其存在状态及混凝效果之间的关系,在此基础上提出了复合混凝剂处理印染废水的复配原则。
