Abstract
The efficient flocculant consists of hydroxide colloid 0.5-15 wt%, acrylamide 50-95 wt% and cationic monomer 0-45 wt%. The hydroxide colloid may be aluminum other, iron hydroxide, magnesium hydroxide or zinc other, and has colloid size of 10-200 nm. The cationic monomer includes DMDAAC or DMC. The organic-inorganic hetero efficient flocculant has in-situ polymerized acrylamide/cationic monomer copolymer linked to the surface of charged inorganic colloid particle, so that it has the synergistic effect of electrically neutralizing effect of inorganic flocculant and the bridging effect of organic polymer and greatly raised flocculating efficiency.
Description
Technical field
The present invention relates to the chemistry in water treatment medicament, relate in particular to a kind of organic and inorganic ionic hydridization efficient flocculant.
Background technology
Inorganic flocculating agent has stronger charge neutralization ability, effect is fast, toxicity is low, raw material sources are wide, characteristics such as use cost is low, organic polymer coargulator is compared with inorganic flocculating agent, it is few to have consumption, flocculation rate is fast, salt is coexisted, pH value and temperature effect are little, the generation sludge quantity is few, and advantages such as easy processing, generally, inorganic flocculating agent and organic polymer coargulator will add step by step just synergy preferably, promptly at first inorganic flocculating agent is brought into play the stability that charge neutrality destroys suspensoid particle in the waste water, then organic polymer is further built bridge and is produced big and real flco, with organic, make composite flocculant after the inorganic flocculating agent mechanically mixing, because the electrolyte effect of inorganic flocculating agent causes organic polymer chain contraction in the solution, particularly with the prolongation of storing, cause the viscosity degradation of composite flocculation agent, effect obviously reduces.
Summary of the invention
The purpose of this invention is to provide a kind of organic and inorganic ionic hydridization efficient flocculant.
The weight percent of hybrid inorganic-organic ionic efficient flocculant is:
Hydroxide colloid: 0.5-15%
Acrylamide: 50-95%
Cationic monomer: 0-45%
Described hydroxide colloid refers to one of aluminium hydroxide, ironic hydroxide, magnesium hydroxide, four kinds of raw materials of zinc hydroxide or more than one, colloidal particle size 10-200nm.Described cationic monomer comprises N, one of N-dimethyl diallyl ammonium chloride (DMDAAC) or two kinds of raw materials of (methyl) acrylyl oxy-ethyl-trimethyl salmiac (DMC).Above-mentioned cationic monomer and acrylamide (acrylamide or AM) are the commercially available prod.
The colloid oxyhydroxide that the present invention will have surface charge is used for polyreaction, effect by bonding, make and form star-like hybrid structure between inorganic particles and the organic polymer chain, in flocculation process, inorganic hydroxide with positive surface charge is by electronegative suspension micelle effect in electrostatic attraction and the waste water, and the absorption by the organic polymer chain, bridge formation etc. show and form the characteristics that flco is big, flocculation rate is fast, the drug effect supernormal performance, thus cause medicament utilization ratio height, dosage to reduce greatly; Suitably adjust the ratio of medicament component, can handle the waste water (as the sludge dewatering of urban comprehensive wastewater and paper waste etc.) of heterogeneity.The present invention is through further investigation and repetition test, finish screening colloid oxyhydroxide and made it modification, adjusting different monomers proportioning and polymerizing condition acquisition and had the task of the hydridization flocculation agent of different mineral colloid oxyhydroxide content and different cationic degrees and different molecular weight, the flocculating effect that makes flocculation agent after the hydridization than hydridization before the organic polymer coargulator of equal not hydridization improve 2～5 times, improve 40～60 times than the mineral colloid flocculation agent before the hydridization.
As known from the above, the present invention is a hybrid inorganic-organic ionic efficient flocculant, its feature has: (1) passes through in-situ polymerization, form the ionic linkage bonding between colloidal inorganic particle surface and the organic polymer chain end of the chain, the reduction of the flocculation validity of the macromolecular chain that macromolecular chain causes the absorption of colloidal inorganic particle when having avoided direct mixing; (2) flocculation rate is fast, flco is big and closely knit, can reach precipitation fully in 10 minutes; (3) dosage is little, and maximum consumption is that waste water per ton adds 0.05 kilogram of effective constituent, can save medicament expense with 30%; (4) because flocculating effect is good, precipitation is complete, the discharge index of handled waste water is stable, and is reliable.
