Abstract
The invention relates to a granular sustained release composite flocculant comprising a polyarylamide coated by a soluble coating material, the residual are aluminum salt and ferric salt. The components according to the weight percentage are as follows: aluminum salt 40%-60%, ferric salt 15%-30%, polyacrylamide 0.1%-10% and soluble coating material 1%-5%. The flocculant of the invention integrates the characteristic of both inorganic and organic flocculants, improves the dosing mode of the medicament, increases the action efficiency of each flocculant by using the process of multistep dissolution sustained release and improves the efficiency of the medicament.
Description
Technical field
The present invention relates to a kind of water treatment flocculant, relate in particular to slow release composite flocculant.
Background technology
The chemical agent coagulating sedimentation is the method for generally using in the water technology.This method has less investment, takes up an area of little, characteristics such as working cost is low, wide adaptability.In water treatment coagulating sedimentation technology, the put-on method of chemical agent is one of gordian technique.Along with the raising that water treatment is required, the normal method that adopts multiple flocculation agent combination to add satisfies requirements in water quality on the medicament dosing method.At present, the subject matter that the adding method that several flocculation agent combinations are thrown mainly exists is that the usefulness performance of flocculation agent is incomplete, and dosage is big, causes the medicament waste, and running cost increases, and produces secondary pollution, the effluent index instability.
Summary of the invention
The purpose of this invention is to provide a kind of slow release composite flocculant.
The technical solution used in the present invention is:
Slow release composite flocculant is particulate state, it is characterized in that containing the polyacrylamide that is coated by the solubility coating in the described flocculation agent particle, and all the other are aluminium salt and molysite.
Described slow release composite flocculant, its component per-cent by weight are: aluminium salt 40-60%, molysite 15-30%, polyacrylamide 1-10%, solubility coating 1-5%.
Described solubility coating is one of starch, gelatine or soluble cellulose or two or more mixtures.
Described aluminium salt is the mixture of Tai-Ace S 150, polyaluminium sulfate, aluminum chloride, polymerize aluminum chloride one of them or two or more arbitrary proportions.
Described molysite is one of in bodied ferric sulfate, ferric sulfate, the ferrous sulfate or the mixture of two or more arbitrary proportions.
Described polyacrylamide is the mixture of cationic-type polyacrylamide, anion-polyacrylamide, zwitter-ion polyacrylamide or non-ionic polyacrylamide one of them or its two or more arbitrary proportions.
Described flocculation agent coating of particles is sphere or almost spherical particle, and particle diameter is 0.1-3mm.
The present invention can adopt injection compound, and chemical cross-linking agent mixes and stirs, and methods such as chemical reagent coating coat poly-propionic acid amide flocculation agent with the solubility coating, has reduced to coat and has gathered the dissolution rate of propionic acid amide in water.When the poly-propionic acid amide that is coated dissolves, at first dissolve coating, poly-then propionic acid amide dissolving itself, thus delayed its dissolution time in sewage, and mineral-type flocculation agent (as aluminium salt of the present invention or molysite) contacts dissolving rapidly with water.Therefore, the inorganic and organic constituent in the slow release composite flocculant is pressed regular hour sequence generation effect, thereby has given full play to the task performance of two class flocculation agents.
Principle of the present invention is: positively charged metallic cation at first dissolves, carry out compression double electric layer, in and the effect of colloid surface electric charge, make colloid take off steady reunion rapidly and form small alumen ustum, polymeric flocculant begins dissolving subsequently, produce and build bridge, net and mend, roll up and sweep effect, alumen ustum is increased rapidly, increase sedimentation speed.
The present invention combines the characteristics of inorganic and organic floculant, has improved the medicament dosing method, and the process of multistep dissolving slowly-releasing has increased the functioning efficiency of various flocculation agents, has improved the usefulness of medicament.Have following distinguishing feature:
1, time series discharges.Once adding the drawback that technology mainly exists for confection solution is: the performance of medicament usefulness is not enough, and dosage greatly, easily causes waste, generation secondary pollution.For the technology that medicament adds in batches, then exist the dispensing time restive, exist medicament can not give full play to drawbacks such as usefulness equally.The present invention handles by each flocculation agent being carried out slowly-releasing, the substep dissolving, make each compound in adding back dissolved process, produce the dissolution time sequence, so promptly provide each medicament relatively independent action time, guaranteed each medicament continuity of action time again, made each medicament can give full play to its performance.
2, action compensating.The slowly-releasing compound had both been brought into play the rapid compression double electric layer of inorganic flocculating agent, form the big characteristics of flco intensity, brought into play again that organic polymer coargulator bridge formation, net are mended, that volume is swept ability is strong, the characteristics that flco is big, it is low to have overcome organic floculant flco intensity simultaneously, the shortcoming that consumption is big.
3, usefulness increases.Owing to adopted multistep slowly-releasing compound, each flocculation agent has been given full play to the usefulness complementarity, medicament sequence effect in time increases the compound overall efficiency, improved the medicament service efficiency, reduced consumption, simplify administration apparatus, reduced running cost, also reduced secondary pollution simultaneously.
