Technical field
The present invention relates to dyeing and printing sewage processing technology fields, and in particular to a kind of decolorization flocculation agent and preparation method thereof.
Background technique
Flocculation is that a kind of application is the most universal, one of simple, the economic important method of wastewater treatment.By flocculant
Treated, and water energy enough reuses, and can effectively alleviate people's life, the insufficient difficulty of industrial water.
Flocculant can be divided into organic polymer coargulator, inorganic salts flocculant and microbial flocculant.It is domestic at present normal
Flocculant is organic polymer coargulator.There are mainly two types of forms for organic polymer coargulator, synthesize organic high score of class
Sub- flocculant and it is natural modified after organic polymer coargulator.
With economic continuous development, the continuous enhancing of environmental consciousness.Efficiently, nontoxic quality-high and inexpensive again easy biology drop
Solution, will not generate secondary pollution green flocculant just becoming current water process in terms of important directions.
