Abstract
The invention discloses a kind of modified humic acid flocculant and preparation method thereof, modified humic acid flocculant is to be formed by aluminum sulfate, aluminium chloride, ferric sulfate or iron chloride solid and humic acid by surface complexation coordination.The kind of the present invention is modified humic acid flocculant, can combine the advantage of inorganic flocculating agent and organic flocculant, preparation method is simple, with it is cheap and environmentally friendly the characteristics of.
Description
Technical field
The present invention relates to specifically related to a kind of modified humic acid flocculant and preparation method thereof, belongs to sewage treatment area.
Background technology
Flocculant is a kind of medicament being most widely used in current waste water control, during flocculation process is sewage treatment process
Indispensable key link.Flocculant can be largely classified into inorganic flocculating agent and organic flocculant.Individually use inorganic flocculation
During agent, flocculating effect is good, but throwing amount is big, costly and undesirable to organic matter removal effect；Macromolecule organic flocculating agent is to having
Machine thing removal ability is strong, but monovalent higher and macromolecule organic flocculating agent is in itself or its hydrolysis, catabolite are poisonous, and synthesis is used
Acrylamide monomer is poisonous, can anaesthetize the nervous centralis of people, application field is by a definite limitation.
The content of the invention
The technical problem to be solved in the present invention, which is to provide, a kind of can combine inorganic flocculating agent and organic flocculant advantage
Modified humic acid flocculant and preparation method thereof.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of modified humic acid flocculant, the modified humic acid flocculant be by aluminum sulfate, aluminium chloride, ferric sulfate or
Iron chloride solid is formed with humic acid by surface complexation coordination.
A kind of preparation method of modified humic acid flocculant, comprises the following steps：
S01：By humic acid water dissolves, it is between 8~10 to adjust pH using strong base solution；
S02：The humic acid solution configured in S01 is added drop-wise to aluminum sulfate, aluminium chloride, ferric sulfate or iron chloride solid
On, while continuing stirring reaction with agitator；
S03：The mixture absolute ethanol washing that S02 is obtained, freeze-drying.
The aluminum sulfate, aluminium chloride, ferric sulfate or iron chloride solid, which include appointing, takes one or two kinds and the above mixed
The mode of conjunction.
The humic acid is extracted from coal.
The strong base solution includes NaOH or KOH.
The humic acid is 1 with the mass ratio of aluminum sulfate, aluminium chloride, ferric sulfate or iron chloride solid:1~1:10.
The temperature of the stirring reaction is 16~28 DEG C, 1.5~3 hours stirring reaction time.
Beneficial effects of the present invention：A kind of modified humic acid flocculant that the present invention is provided and preparation method thereof, passes through table
Face complex coordination effect will be combined one without flocculant (including aluminum sulfate, aluminium chloride, ferric sulfate or iron chloride) and humic acid
Rise and form organic-inorganic composite flocculant, preparation method is simple, react humic acid in the modification humic acid flocculant of synthesis and originate
Extensively, have the advantages that cheap, and humic acid belongs to macromolecule organic, and itself includes a variety of work such as carboxyl and phenylol
Property group, can possess good removal effect to the organic pollution and heavy metal ion in water body, overcome exclusive use
The inorganic flocculating agent defect low to organic matter removal effect, humic acid Stability Analysis of Structures in addition will not be as macromolecule organic flocculating agent
Decompose or degraded produces harmful substance, the characteristics of possessing environmental protection.
