Abstract
The invention discloses an acrylamide and ethylenediamine flocculating agent. The acrylamide and ethylenediamine flocculating agent is prepared from, by weight, 60-70% of acrylamide, 20-30% of ethylenediamine and 10-20% of sodium persulfate. Meanwhile, the invention further discloses a preparation method of the acrylamide and ethylenediamine flocculating agent. Compared with the traditional technology, a certain amount of polarity functional groups which can absorb solid particles suspended in water are contained in molecular chains, large floccules are formed between the particles in a bridging mode, and therefore particle sedimentation in suspension liquid is effectively accelerated, filtration is promoted, and the acrylamide and ethylenediamine flocculating agent and the preparation method are widely used in industrial wastewater treatment.
Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of acrylamide quadrol flocculation agent and preparation method thereof.
Background technology
Flocculation agent mainly contains inorganic flocculating agent, organic polymer coargulator and microbial flocculant, is mainly used to dispose of sewage.And organic polymer coargulator is mainly used for Refinery Wastewater.Acrylamide series flocculation agent is high with its molecular weight, and flocculation bridge formation ability is strong and demonstrate the superiority in water treatment.
Flocculation process is most widely used general, the most general technique in current lot of domestic and foreign water technology, it is link indispensable in wastewater treatment, the quality of flocculating effect often determines the operation conditions of follow-up flow process, final outflow water water quality and expense, selects which kind of flocculation agent for improving effluent quality, reduces water producing cost and have very important Technological Economy to be worth.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, provides a kind of acrylamide quadrol flocculation agent.
Another object of the present invention is to the preparation method that aforesaid propylene acid amides quadrol flocculation agent is provided.
Technical scheme: in order to reach foregoing invention object, the present invention has specifically come like this: a kind of acrylamide quadrol flocculation agent, comprise the component of following weight percent: the acrylamide of 60 ~ 70%, the quadrol of 20 ~ 30% and the Sodium Persulfate of 10 ~ 20%.
Wherein, preferably, be made up of the component of following weight percent: the acrylamide of 65%, the quadrol of 23% and the Sodium Persulfate of 12%.
Prepare a method for acrylamide quadrol flocculation agent, measure each material by formula, acrylamide and quadrol are carried out polyreaction at 55 ~ 75 DEG C, continue 2 ~ 4 hours, after polyreaction, temperature is reduced to room temperature, then add Sodium Persulfate uniform stirring 30 ~ 40 minutes.
Beneficial effect: the present invention is compared with conventional art, owing to containing the solids suspended in a certain amount of polarity merit functional group energy planar water in molecular chain, making builds bridge between particle forms large throw out, thus the particle precipitation effectively accelerated in suspension, promote to filter, be widely used in chemical industry effluent process.
