Abstract
The invention discloses an oil refining wastewater composite treating agent and a preparation method thereof. The treating agent is composed of porous minerals, a foaming agent and a chitosan solution. The preparation method comprises the steps of: roasting the porous minerals; adding the foaming agent; spraying the chitosan solution; granulating by a granulating machine; and foaming by heating in an oven to produce the oil refining wastewater composite treating agent. For heavy metal ions, the chitosan is good in chelation; the foaming agent increases the specific surface area; and due to non-uniform mixing of the mineral materials and the foaming agent, different grain sizes of the granulated particles and different densities of the produced oil refining wastewater composite treating agents, partial treating agents can float on the water level and partial treating agents can be dispersed in the water to adsorb floating oil, emulsified oil, dispersed oil and the like in the wastewater. The long molecular chain of the chitosan can net and flocculate large pollutant particles; after the chitosan is compositely foamed with the mineral material with big specific surface area, contactpoints with the pollutants are added; and the adopted mineral material and chitosan are nontoxic and harmless, so that no secondary pollution is caused. The preparation method, disclosed by the invention, has the advantages of simple production technology and low production cost.
Description
Technical field:
The present invention relates to a kind of activator of use in waste water treatment, especially make the preparation method of the shitosan composite water disposal agent of carrier with porous mineral.
Background technology:
Refinery(waste) water is the factory effluent that produces during PETROLEUM PROCESSING is handled, and its complicated component mainly contains a large amount of greases, phenols, sulfide, ammonia nitrogen and various heavy.Existing processing method is poor effect often, for example:
Settling methods, this method utilization is oily, water density is poor, and separating oil aqueous mixtures under the gravity effect be a kind of modal processing method, but this method can't be handled dispersed oil, oil emulsion;
Filtration method, this method can be removed suspension, dissolved oil in the water by adopting filter course or microporous barrier, but filter needs often flushing, is unfavorable for extensive wastewater treatment;
Flocculence, this method generate flocculate absorption tiny oil droplets and reach the effect of removing greasy dirt by adding flocculant in waste water.Flocculant commonly used is divided into organic flocculant and inorganic flocculating agent two classes, and inorganic flocculating agent is mainly bodied ferric sulfate, aluminium polychloride etc., and this class flocculant use amount is big, is easy to generate a large amount of mud.Organic flocculant is mainly polyacrylamide, and this class flocculant can produce secondary pollution;
Absorption method, this method is adsorbed organic matter in the waste water by adopting inorganic porous material such as active carbon, diatomite, bentonite, zeolite or oil-absorbing resin class organic material, but the porous material adsorbance is less, and adsorptive selectivity is poor, the oil-absorbing resin cost is higher, all has certain deficiency.
Summary of the invention:
Purpose of the present invention just is at above-mentioned the deficiencies in the prior art, provides a kind of and will activate the porous mineral material and shitosan is compound and the refinery(waste) water composite treating agent of the preparation of foaming;
Another object of the present invention just provides a kind of preparation method that will activate the refinery(waste) water composite treating agent of the compound and preparation of foaming of porous mineral material and shitosan.
The refinery(waste) water composite treating agent, each material composition is by weight percentage:
Porous mineral 75-95%
Blowing agent 0.1-5%
Chitosan solution 4.9-20%
Chitosan solution is that the concentration of chitosan solution is 0.02-0.5g/ml with the acetate dissolution shitosan of concentration 1-6wt%.
Described porous mineral is one or both in finger bentonite, expanded perlite, the zeolites porous mineral.
In the preferred sodium acid carbonate of described blowing agent, the agent of Celogen Az powdery low-temp foaming one or both.
The preparation method of refinery(waste) water composite treating agent comprises following order and step:
A, porous mineral is milled to 200 orders;
B, will be milled to 200 purpose porous minerals roasting 1-10h in Muffle furnace, sintering temperature is 200-500 ℃;
C, add the blowing agent of 0.1-5wt% in the porous mineral after modification by weight percentage, in high-speed mixer, mix;
D, spray chitosan solution 0.05-0.2ml by the every gram of mixed weight;
E, carry out granulation with comminutor then, particle diameter is 0.5-5mm;
F, granulation gained particle is heated 50-150 ℃ in baking oven, be that the 30min-4h foaming makes finished product heat time heating time.
Beneficial effect: by modification by calcination porous mineral material, removed impurity such as the sulfide in the mineral material, fluoride and organic matter, dredged the duct, improved pore structure, improved the adsorption effect to pollutant in the waste water.The shitosan that adopts is a kind of organic polymer that contains the various active group, and the organic and inorganic particulate in the water body is had better suction-operated, and heavy metal ion is had good chelation, has certain germicidal efficacy simultaneously.In addition, shitosan is macromolecular material, chitosan solution has good viscosity, has played the effect of bonding, plasticising in granulation process.The foaming of introducing blowing agent has increased adsorption specific surface area, is conducive to improve adsorption effect.Because it is inhomogeneous to exist mineral material to mix with blowing agent, the particle unequal factor of being heated in granulation gained particle grain size difference and the foamable process, the finished product density difference that makes, cause a part of inorganic agent can float on the water surface, part inorganic agent is scattered in the water, and the floating oil in the refinery(waste) water, oil emulsion, dispersion wet goods are all had the absorption fixed effect.With porous mineral material and the compound use of macromolecule organic, the porous mineral material specific area after the activation is big, is conducive to adsorb in a large number the pollutants such as grease, sulfide and ammonia nitrogen in the refinery(waste) water; The long strand of the shitosan bulky grain pollutant of can net catching, flocculate with the mineral material of bigger serface after the compound and foaming, has increased the contact point position with pollutant, can form big floc sedimentation after having improved adsorption effect and absorption, is beneficial to post-processed.The inorganic mineral material and the shitosan that adopt are all nontoxic, can not produce secondary pollution.Production technology is simple, and low production cost is compound with activated porous mineral material and macromolecule organic shitosan, and improves adsorption specific surface area and density by the method for foaming, is used for Refinery Wastewater to have obtained effect preferably.
