Abstract
The invention discloses a preparing method of organic polymer-diatom earth composite coagulant, which comprises the following steps: pre-proceeding diatom earth raw material firstly; compositing with organic macromolecular flocculant; getting the organic polymer-diatom earth composite coagulant.
Description
Technical field
The present invention relates to technical field of waste water processing, specifically relate to a kind of preparation method of organic polymer-diatomaceous soil composite coagulating agent.
Background technology
The waste water water yield of textile printing and dyeing or paper industry is big, the colourity height, and change of water quality is big, organic pollutant content height, the component complexity, and also in recent years, the use of PVA slurry and New-type adjuvant rolls up organic pollutant content in waste water of bio-refractory.Relatively difficulty and cost are very high with single medicament or art breading, need develop efficient, economic treatment of dyeing wastewater medicament on the basis that different medicaments are made up.Diatomite is that the remains of the diatoms that grows in ocean or the lake are at subaqueous deposit, through the physical environment effect and a kind of non-metallic minerals that forms gradually.It has unique diatom shell structure, strong adsorptivity, bigger serface, highly porous, and as a kind of resourceful porous natural product, it is cheap, is that raw material prepares water conditioner and has remarkable economic efficiency with the diatomite mineral therefore.At present, diatomite often is used for the processing of waste water such as tap water, swimming-pool water, process water, boiler recirculated water separately, and adopt organic high molecular polymer compound with activation diatomite, bring into play the synergistic effect of the two and do not appear in the newspapers with the method for preparing compound coagulant.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of organic polymer-diatomaceous soil composite coagulating agent.
In order to achieve the above object, the technical solution used in the present invention is as follows:
With the diatomite mineral is raw material, and the diatomite ore raw material is carried out pre-treatment, handles back diatomite and mixes in the aqueous solution with the organic high molecular polymer of 0.1～20wt% diatomite weight, stir make it homodisperse after, dry, pulverize and make finished product after levigate.
Described pre-treatment is meant the method for roasting or cleanup acid treatment.
It is characterized in that described calcination process is the roasting temperature 1～10h at 300～700 ℃.
Described cleanup acid treatment is meant hydrochloric acid, sulfuric acid or the salpeter solution processing 2～8h that adopts 5～20% concentration.
Described organic high molecular polymer can be the mixture of poly dimethyl allyl ammonia chloride, poly-Dyhard RU 100 formaldehyde, polyacrylamide one of them or its two or more any ratios.
Described polyacrylamide is the mixture of anionic polyacrylamide, cationic polyacrylamide, non-ionic polyacrylamide or zwitter-ion polyacrylamide one of them or its two or more any ratios.Coagulating agent of the present invention adds in the processed waste water in the usual way with the pulvis state when reality is used.
Preparation of the present invention comprises two processes: at first being the pre-treatment of diatomite material or being called the activatory process, secondly is activation back diatomite and organic polymer coargulator compound process.
Among the present invention, activation treatment can be removed the impurity such as organism in the raw mineral materials, improves its pore structure, and makes oxide compounds such as iron in the diatomite mineral, aluminium, calcium dissociate out, improve its surfactivity, thereby improve its adsorption and effect of flocculant thereof pollutent in the waste water.And activation back diatomite and organic polymer coargulator is compound, and one side brings into play that compression double electric layer, charge neutralization, bridge formation, the volume of polymeric flocculant are swept, net is caught effect, precipitates rapidly and removes the bigger pollutent colloid of those particles; On the other hand, utilize diatomaceous bigger serface, can adsorb and remove those difficult small particle size pollutents of removing (as dye molecule etc.); Simultaneously, the high advantage of performance diatomite surfactivity improves the active of organic polymer coargulator and contacts the position with the pollutent colloidal, plays and helps the effect of coagulating, thereby speed of response is accelerated, and the utilization ratio of flocculation agent improves, and dosage reduces greatly.
The beneficial effect that the present invention has is: the present invention is by after carrying out the lattice activation to the diatomite ore raw material, compound with organic polymer coargulator, the cooperate optimization effect of performance polymeric flocculant and modification infusorial earth mineral coagulant aid, thus prepare the organic polymer-diatomaceous soil composite coagulating agent that textile dyeing and finishing, paper industry sewage is had remarkable purification and decoloration effect.And because the aboundresources of diatomite ore raw material, cheap, therefore coagulating agent of the present invention is recited above to the advantages such as sewage disposal speed is fast, effective, dosage is little except having, and also has the lower advantage of production cost.Technology of the present invention is simple, and the diatomaceous earth products after compound is significantly improved to the treatment effect that contains organic wastewater, can be applicable to print and dye, the processing of trade effluent such as papermaking.
