Description
Technical field:
Adopt the molten gas technology of high molten ozone amount and microbubble aeration process, be combined ozone, ultraviolet catalytic and photosensitizing chemical catalyzer and form a kind of deep oxidation water treatment method and device, not only utilize dissolved oxygen and ozone, the great amount of hydroxy group free radical mainly utilizing chemical reaction to excite participates in oxidation and forms so-called chain reaction, be that a kind of oxidation capacity is higher, oxidation rate is advanced oxidation processes faster.This invention is not only applicable to the sterilization of common drinking water, is more suitable for the highly toxic organic pollutant of high density of difficult for biological degradation in oxidative degradation water.Both can using as independently sewage water treatment method and device, also can use as reducing the pre-treatment method of concentration of wastewater and toxicity and existing biodegradable water treatment method and coordinative composition of equipments.Belong to water-treatment technology field.
Background technology:
Ozone is a kind of strong oxidizer, can be oxidized various organism.20 century 70s, people begin one's study and utilize ozone as the sterilizing agent of tap water, swimming-pool water, and obtain good effect.Ozone not only can be applied in drinking water treatment, also can be used in the process of waste water.The effect of ozone in water and waste water can be generalized into three classes: one is be used as sterilizing agent or sterilant; Two is the oxygenants being used as oxidation organic pollutant; Three is for other processing units (comprising coagulation, flocculation, precipitation, bio-oxidation, charcoal absorption etc.) provide dissolved oxygen and ascending gas bubbles.
High pressure dissolving dissolved ozone is the effective ways improving ozone solution amount.Chinese patent (publication number CN104043356A), (publication number CN201330188Y) are proposed the method utilizing microbubble to improve water body dissolved-air rate in dissolving; Chinese patent (publication number CN103736409A), (publication number CN202415245U) adopt the way controlled respectively to gas-liquid mixing pump delivering gas amount and discharge to obtain dissolved air water at dissolving, and dissolved air water is equipped with suitable reliever again will produce a large amount of uniform microbubble.But dissolving function singleness in these technical schemes, only provides and store high concentrations dissolved air water.
The advantages such as oxidation organic pollutants ability is strong although ozonation technology has, decomposition rate fast, non-secondary pollution, are used alone ozone, still there is O
3solubleness in water is low, and affect the problem of oxidation efficiency, ozone oxidation has selectivity, and different types of organic matter degradation ability and speed exist very big-difference.In ozone oxidation process, add UV-light and the catalyzer with photocatalytic effect is one of effective ways addressed this problem, belong to the category of degree of depth oxygen technology.Advanced oxidation processes, also known as high-level oxidation technology (Advanced Oxidation Process, AOP) refer to oxidation capacity exceed all common oxidants or oxidizing potential close to or reach Hydroxyl radical HO level, serial free chain reaction can be carried out with organic pollutant, thus destroy its structure, make it progressively be degraded to harmless low-molecular-weight organism, be finally degraded to CO

2with air as oxygenant, under thermal effect, produce Hydroxyl radical HO.Photocatalytic oxidation is in reaction soln, add a certain amount of catalyzer, makes it under the irradiation of UV-light (UV), produce Hydroxyl radical HO, is processed by the strong oxidation of HO to organic pollutant.
Ozone content, illumination frequency and intensity, catalyst component and quality etc. all can affect the ability of oxidizing reaction and the oxidation rate of sewage.Chinese patent (publication number CN202625991U) proposes a kind of ultraviolet light ozone catalyst reaction device, but catalyzed reaction environment is in non-pressure vessel, ozone saturation solubility is smaller, low ability and the speed that still govern ultraviolet catalytic oxidation reaction of the ozone saturation solubility of the ozone oxidation reaction (later claiming ozonize) under photochemical catalysis.
According to the phase of used catalyst, ozone catalytic is divided into homogeneous catalysis ozonize and multi-phase catalytic ozonation.The former is liquid catalyst mainly, and the latter's mainly solid catalyst.Because homogeneous catalyst can form homogeneous concentration in the solution, therefore there is the advantages such as activity is high, speed of response is fast.But post catalyst reaction and sewage blending, be difficult to again separate, cause catalyzer to cause financial loss because of loss, too increase the burden of the subsequent disposal of catalytic ozonation reaction, add the complicacy of catalytic ozonation technique, improve cost of water treatment.Compared with homogeneous catalyst, heterogeneous catalyst exists in solid form, is easily separated from water, and technical process is simple, has both avoided the loss of catalyzer, and has also reduced follow-up processing cost.In the research of nearly more than ten years, heterogeneous catalyst obtains more favor.
The aerating apparatus of routine techniques can only produce grade bubble, and bubble directly floats.Ozone or other gas residence time in water is very short, so molten ozone amount is lower in water.Because ozone can not fully dissolve in the middle of water body, some pollutent retaining on a small quantity in water body is difficult to remove clean, even if the method for the excessive ozone that exposes to the sun as usually adopted, produces effects also not obvious.It is also one of difficult problem processing chemical pollution that trace chemistry pollutent difficulty is removed.The method for subsequent processing such as biological degradation are often needed to be supplemented.
The present invention proposes a kind of method of more high efficiency deep oxidation organic pollutants on the basis setting up a new chemical reaction equipment system, producing great amount of hydroxy group free radical by increasing photo-catalysis function in the tank body of the molten ozone water environment of height, reaching the object increasing oxidation capacity, improve oxidative degradation rate.
Summary of the invention:
The present invention relates to a kind of water treatment method and device of deep oxidation, water treatment procedure is divided into three sections, and order completes in three kinds of devices, they are photochemical catalysis oxidation reaction apparatus and continuity reaction microbubble aerating apparatus under ozone and sewage mixing device, high pressure respectively.
Ozone and sewage mixing device are made up of source of oxygen and the reducing valve of attaching troops to a unit, oxygen flow meter, oxygen conveying pipe, ozonizer, gas-liquid mixing pump, Venturi liquid gas combining nozzle etc.
The working process of ozone and sewage mixing device is, gas-liquid mixed mouth inspiration simultaneously sewage and the ozone that have adjusted flow of Venturi tube structure, gas-liquid mixing pump quick runner smashes the molten ozone water of the high molten ozone amount of bubble formation, and pump outlet end exports high pressure solution (ozone) air water.
In ozone and sewage mixing device, the inlet pipe between ozonizer and Venturi liquid gas combining nozzle is provided with check valve, oppositely enters ozonizer with bilge water resisting.
In ozone and sewage mixing device, the adjustment of ozone flow is to meet saturated dissolved gas institute air demand under mixing pump output pressure for the upper limit, and exceed this saturated tolerance and gas-liquid mixing pump output pressure will be caused to decline, even fluid stops flowing.
Under high pressure, photochemical catalysis oxidation reaction apparatus is by high pressure dissolving and the water inlet interface that is contained in outside tank, the release valve of water outlet mouthpiece, tensimeter, rate of discharge variable valve, water sampling valve, dissolved air water transfer lime, tank top automatic blow off valve valve air relief, backflow tracheae, pot bottom, is contained in the compositions such as the ultraviolet lamp in tank, light-sensitive catalyst.
Under high pressure, the working process of photochemical catalysis oxidation reaction apparatus is: the dissolution of contaminated water under high pressure has the ozone higher than meltage saturated under normal pressure, under UV-light and UV sensitive catalyst environment, ozone oxidation reaction can produce the stronger hydroxyl radical free radical of a large amount of oxidation susceptibility, be equipped with other oxydised component, as ozone ion, dissolved oxygen molecule etc., obtain stronger oxidation capacity and oxidation rate faster.
Under high pressure in photochemical catalysis oxidation reaction apparatus, catalyzer should have large surface-area, and to facilitate the sewage of irradiating ultraviolet light and contact flow, catalyzer can exist with the form of coating form and filler, is not subject to the restriction of concrete existence form and shape.
Under high pressure in photochemical catalysis oxidation reaction apparatus, the automatic vent valve air gate that top is installed connects a backflow tracheae, backflow tracheae is confluxed by threeway and oxygen conveying pipe, and in reaction unit, a small amount of oxygen overflowed is used again, and device systems runs and realizes gas-tight.
Under high pressure in photochemical catalysis oxidation reaction apparatus, the generation of tank pressure and maintain by tensimeter, go out water regulating valve and air input variable valve (oxygen flow meter) completes jointly, tensimeter not only shows pressure, also be the foundation that air input regulates: display pressure when air input is zero is maximum, when air input excess, display pressure can sharply decline, and when pressure-stabilisation is in the level a little less than top pressure, air input is appropriate.
Continuity reaction microbubble aerating apparatus is made up of high-pressure sewage Outlet Pipe and micro bubble releasing device, and wherein transfer lime gos deep into the former container bottom of sewage, and transfer lime head installs one or one group of micro bubble releasing device.
The working process of continuity reaction microbubble aerating apparatus is: high pressure dissolved air water is by micro bubble releasing device to sewage water bottom release dissolved air water, and in high pressure dissolved air water, dissolved gases overflows and is crashed to pieces into the bubble of micro-or nano size under the effect of reliever turbulence structure.The long-time disperse of microbubble is in the middle of water body, and the oxygen in bubble, ozone continue to dissolve to water body, add in reaction unit and to produce and the hydroxyl radical free radical retained continues its oxidation reaction process in water body.
The micro bubble releasing device of continuity reaction microbubble aerating apparatus excites turbulent flow moving and vibration, and in order to smash the tuyere arrangement of bubble, the present invention adopts vibration two-slices series of holes structure release device, but is not limited to use this reliever.
The vibration two-slices series of holes structure release device that continuity reaction microbubble aerating apparatus adopts is made up of the same size thin slice orifice plate of reliever main body, installation sealing-ring, front and back arranged in co-axial alignment, the elastic seal ring providing sealing and interval to support for orifice plate and scatterer.High pressure dissolved air water is by producing fixing high-frequency vortex street after vertical orifice plate, vortex street two orifice plates between the high frequency oscillation of dissolved air water by producing during the first orifice plate, the partition adjustable space initiation of this concussion between two orifice plates is resonated and continues and strengthen this resonance, separate out in saturated dissolved gas earthquake under high pressure, smashed by concussion again and become microbubble, microbubble enters water body with current by scatterer, and undersaturation sewage water body will continue the oxidizing gas absorbing and dissolve in bubble.
Beneficial effect:
1) ozone is without waste.The ozone of gaseous phase is easy to reduction after generation becomes oxygen, and after ozone generation, direct and sewage mixing, at utmost can utilize ozone;
2) oxidation efficiency is improved.The rotation of gas-liquid mixing pump quick runner is pressurization is also mixing process.Gas-liquid mixed supercharging can make the pressure ratio of liquids and gases, and kinetic energy ratio and potential energy ratio etc. change.Now, ozone forms a large amount of microbubbles, and gas diameter is 0.2-0.3um, therefore O
3suddenly increase with the contact area of water, the total area is higher than general bubble by 10
3-10
4doubly, O
3dissolution rate significantly improve, so water outlet is in high pressure saturated dissolved gas state substantially.In high pressure dissolving, in water, molten ozone amount is sufficient, is conducive to oxidation reaction;
3) increase oxidation capacity, improve oxidation rate.Under the katalysis of ultraviolet lamp and photosensitizing chemical catalyzer, generate the hydroxyl radical free radical that a large amount of oxidation susceptibility is stronger, the hydroxyl radical free radical that the oxygen molecule dissolved in water, ozone ion and activity are stronger and Components of Organic Pollutants close contact in the liquid phase, not only increase oxidation capacity, and improve oxidation rate.
4) catalyst choice leeway is large.Catalyzer or the optionally catalyzer of broad spectrum suitably can be selected according to pollutant type.By appropriately combined, the eutrophy sewage of common Nitrogen-and Phosphorus-containing, chemical dye sewage etc. can not only be processed, the reluctant trade effluent that agricultural chemicals, hormone and electroplating wastewater, percolate etc. are generally acknowledged can also be processed.
5) ozone utilization rate is high, consumption is little.Due to gas-liquid two-phase simultaneously and suck gas-liquid mixing pump continuously, mixing pump does not allow to suck excess air, and gas exceedes saturated dissolved gas, and pump pressure will be caused to reduce even flow is zero; This characteristic using saturated quantity of dissolved gas as restricted condition of gas-liquid mixing pump has also achieved the feature that ozone utilization rate of the present invention is high, air consumption is little.
6) subsidiary stink is little.Due to inexcessive use ozone, the sewage smells also corresponding minimizing that ozone taste and band carry;
7) oxidizing reaction is lasting, sphere of action is large.The ozone of saturated dissolving under high pressure produces microbubble aeration under reliever effect in normal pressure waste water container, and microbubble is that milk state spreads in water body, and ozone continues to dissolve to undersaturation water body, and ozone oxidation reaction still proceeds in water body.
8) non-secondary pollution thing.Deep oxidation water treatment method only introduces a kind of material of oxygen.Only can react and generate oxidizing gas, oxide precipitation and water, can not secondary pollution be produced.
9) volumetric efficiency is high.Device systems is simple, and function is concentrated.So volume is little, function is strong.
10) use flexibly.Both can separately as the deep oxidation method and apparatus of process chemical organic compounds waste water, also as the pre-treating process of biological treatment of sewage, necessary reduction organic contamination substrate concentration can be provided for subsequent bio water technology and weaken anticipating of chemical toxicity.
