Abstract
The present invention discloses a treatment process for absorbing and regenerating high COD sewage by using a nanometer material, wherein the treatment process adopts an adsorption unit, a magnetic separation unit and a photocatalytic regeneration unit. During a sewage treatment, iron-containing nanometer micro-spheres being subjected to re-pelletizing are directly poured into the adsorption unit, and complete stirring is performed, such that the nanometer micro-spheres and sewage in an adsorber are subjected to mixing contact so as to completely adsorb organic matters, ammonia nitrogen compounds and other COD in the sewage; the magnetic separation unit adopts an external magnetic field to precipitate the nanometer micro-spheres achieving the saturated adsorption state on the bottom of a separator without loss along with the treated water flow, wherein the COD-treated clear water flows out from the separation unit so as to be discharged; and the photocatalytic regeneration unit adopts a high power ultraviolet ray lamp to carry out photocatalytic regeneration on the COD-rich nanometer micro-spheres collected by the magnetic separator, and after irradiation with ultraviolet ray, the COD adsorbed by the nanometer micro-spheres is efficiently decomposed into water and carbon dioxide gas so as to complete a harmless treatment process of COD degradation. According to the present invention, the efficient treatment can be performed on the difficultly-treated high COD sewage, the discharge can meet the standard, the treatment cost of the process is low, and significant economic and social benefits are provided.
Description
Technical field
The present invention relates to technical field of sewage, relate in particular to the removal of pollutent and the technique of processing of municipal effluent, sanitary sewage and the industrial organic waste water (as pharmacy waste water, dyeing waste water, smelting wastewater etc.) that are rich in COD organic pollutant.
Background technology
Organic pollutant is the principal pollutant in all kinds of waste water including various trade effluents and sanitary sewage, and these organism can resolve into various biological treatments carbonic acid gas and water under both economical condition.Normally used biological treatment comprise use aerobic bacteria activated sludge process, use the anaerobic treatment method of methane fermentation bacterium, also useful yeast carries out the yeast method of aerobic treatment recently.The various Anaerobic cultural methods such as wherein, activated sludge process etc. utilize the method for aerobic bacteria to be mainly used to process low-concentration organic waste water, UASB (to upper reaches Sludge Bed) are mainly used to process the higher waste water of organic concentration.Yeast method is just to start in recent years a kind of biological treatment of being applied, and it is mainly used to process some common biological treatments and is difficult to competent waste water.At present using yeast bacterium method is disposed of sewage often for processing food industrial wastewater, and a small amount of document relates to pharmacy waste water, and the patent CN94110771.X of Qingdao Marine University relates to and uses yeast method to process antibiotic pharmacy waste water and utilization of waste material.
High-enriched organics sewage is that usually said high-COD waste water belongs to a very unmanageable class sewage in some cases, this class Biodegradability of Wastewater is poor, the material of relative molecular mass from several thousand to several ten thousand, as smelting wastewater under the aromatic substance in coking chemical waste water, oil-contaminated water of oil field, pharmaceutical industry waste water, high salt concentration etc., conventional treatment process is processed very difficult, the residual a large amount of difficult degradation harmful organic substances of water outlet, it is high, uneconomical that existing treatment process exists energy consumption, floor space is large, easily pollutes the shortcomings such as surrounding environment.Meanwhile, the cost of the high processing of some treatment process makes enterprise be difficult to bear, and seeking efficient, economic high COD treatment process is a bottleneck difficult problem of restriction water treatment field.
Chinese patent CN02137442.2 has announced a kind of use Zeolite-bio combined adsorption regenerative sewage treating process, the method is used the organism formation in zeolite adsorption sewage to have compared with the zeolite sludge of high microorganism activity, and then use biological treatment, recirculation to use zeolite to carry out sewage disposal;
Chinese patent 201110071616.4 has been announced a kind of equipment of renewable photocatalytic advanced oxidation water treatment, the method is used nano photo-catalytic material oxygenolysis organism under UV-light, uses microporous membrane to stop a kind of device that photocatalyst powder body material runs off simultaneously;
Chinese patent CN200620173147.1 has announced a kind of device that can on-line regeneration active carbon adsorption material, and the method can be disposed of sewage and high temperature regeneration absorbent charcoal material simultaneously, greatly reduces the use cost of gac.
COD amount during above patented technology is all intended to dispose of sewage by adsorption technology on the one hand, have simultaneously and can regenerate to reduce materials'use cost, but all ubiquity sewage load is limited, treatment time is long, the shortcoming that handling object is pointed, as absorbent charcoal material, to the adsorption treatment poor ability of the polarity organic pollutant in sewage, yeast method is just for specific pharmacy sewage processing, and processing cost is still higher.
Summary of the invention
For above-described deficiency, goal of the invention of the present invention is to provide a kind for the treatment of process that uses nano material absorption regeneration high COD sewage, this technique combines performance and the efficient oxidation Photocatalytic Regeneration technique of the efficient adsorption organic pollutant of Nano microsphere, used magnetic separation technique simultaneously, can be simply, efficiently the saturated Nano microsphere of absorption is separated from waste water, enrichment out, thereby solved the separation difficult problem of nano material in water treatment field.
Goal of the invention of the present invention is achieved by the following technical solution:
Use a treatment process for nano material absorption regeneration high COD sewage, this treatment process is made up of absorbing unit, magnetic separating unit, Photocatalytic Regeneration unit.In the time of sewage disposal, to directly be added in absorbing unit through the ferri nano microballoon after granulation again, by abundant stirring, make Nano microsphere mix and contact with the sewage in adsorber, the COD such as the organism in sewage, ammonia nitriding compound are adsorbed fully; Magnetic separating unit uses externally-applied magnetic field, the saturated Nano microsphere of absorption is deposited in to separator bottom, and can run off with current after treatment, flows out discharge through COD clear water after treatment from separating unit; Photocatalytic Regeneration unit will use superpower UV-lamp to carry out Photocatalytic Regeneration to the Nano microsphere that is rich in COD of collecting in magnetic separator, after uviolizing, the COD of Nano microsphere absorption is resolved into water and carbon dioxide efficiently, thereby has completed the innocent treatment procedure of COD degraded.
The Nano microsphere that described special surface is modified not only has the adsorptive power of broad-spectrum high efficacy to organic pollutant, no matter be organic polarity power, all can from water, be adsorbed by it, and modify by surface magnetism, adsorb under saturated Nano microsphere outside magnetic field attraction, easily realize enrichment, be convenient to Photocatalytic Regeneration.
Adopt the present invention, can efficiently process for difficult high COD sewage, qualified discharge, and this art breading cost is low, has obvious economic benefit and social benefit.
