Description

Cooperating type advanced oxidation reaction unit

One, technical field:

The utility model relates to water treatment device, and especially chemistry (catalysis) oxidation style is the device of water treatment.

Two, background technology:

At present, oxygenant or photochemical catalytic oxidation are adopted in common sewage decontamination more, also have both shared, make sewage become new water source, and water resources is fully utilized.But there is requirement height to oxidation pre-treatment (adjusting) as flocculation, PH, the running cost height, there are deficiencies such as secondary pollution, for the reluctant high density of usual way, difficult degradation, poisonous and hazardous organic waste water, then need adopt the scrubbing technology that cost is high, equipment is complicated as agricultural chemicals waste water etc., treatment effect is not thorough.

Three, summary of the invention:

The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of cooperating type advanced oxidation reaction unit is provided, compact construction, and volume is little, improves treatment effect, thoroughly purifies and can not introduce secondary pollution.

The technical scheme that the utility model is adopted for achieving the above object is: cooperating type advanced oxidation reaction unit, relate to oxidation reactor, and add magnetic field on the reactor sewage inlet pipeline.Magnetic field can be frequency sweep magnetic field, permanent magnetic field or electromagnetic field.

Fixedly mount ultrasonic transducer on the reactor outside wall surface.Also can will be fixed on the reactor wall face after the ultrasonic transducer sealing.

Reactor wall transparent window, reactor are installed light source outward.Also can in the reactor printing opacity sleeve pipe be housed, light source is housed in the sleeve pipe.Described light source adopts ultraviolet source.

Principle of the present utility model is: water body flows through magnetic field, cutting magnetic line and obtain extra energy, thereby except that increasing the specific absorption of water to light, the surface tension of water is descended, penetrating power strengthens, and more than can be described as sensitizing effect, all helps the carrying out of oxidizing reaction.Through magnetic treatment, the hydrogen bond of associated water is bent, twist, the intensity of key reduces, and so just can discharge the former colloidal solid that is wrapped up by associated water bunch group, makes it to be directly exposed under the attack of oxygenant.Water has the memory effect of long period to magnetic treating result, and long reaches several days, like this, has just guaranteed to still have magnetic action in oxidizing reaction.

Light source, different sewage can be selected the multiple light source that comprises sunlight for use.Especially UV-light is the short light wave of wavelength, and photon energy is higher, is very easily absorbed by the organism of almost all kinds, when oxygenant exists, produces the reaction of intensive photochemical oxidation.UV-light can make organic matter degradation, with oxygenant synergy, produces hydroxyl radical free radical, oxidation capacity much larger than both former capable add and.Photoassisted oxidation has two problems: one is that the irradiation degree of depth is little in sewage.According to less than the place, just do not have light to help reaction, need to stir; Another is that optical transmission window is easy to fouling in sewage, needs cleaning.These two problems can be by magnetic field and ultrasonic finishing.After the water body process magnetic field treatment, optical property generation mutation, thus the receptivity of light is strengthened.

The ultrasonic function that intensive stirring action and cleaning solid surface are arranged.Ultransonic cavatition is on record, and the shock wave that cavitation causes has produced partial high temperature and high pressure environment, dirt that can those utmost point difficult degradations of oxidation.

Can discolor with ozone earlier for colorful wastewater, increase transmittance, simultaneously, separately or with other oxygenant (as hydrogen peroxide) jointly as primary oxidant.

The utility model has the advantages that: in chemical oxidation reaction, introduce wave field, resemble light wave, sound wave and magnetic field etc., make it with oxygenant by collaborative, reinforcement, sensibilized, greatly improve treatment effect, reach the purpose of thorough purification, at normal temperatures and pressures operation, compact construction, volume is little.The use of wave field does not increase the difficulty of operation, and investment slightly increases, but for the raising of treatment effect, is acceptable.Particularly in some occasion, as supersalinity, intermittently or seasonally produce dispersive sewage on that produce, that temperature is lower, the space, this device is most economical selection.When using ozone as oxygenant, do not need other chemical, only need power consumption power, very convenient, and can not introduce secondary pollution, social benefit and remarkable in economical benefits.

Fig. 2 is the built-in multicell structural representation of the utility model.

Five, embodiment:

Cooperating type advanced oxidation reaction unit as shown in Figure 1, be the external placed type single cell structure, oxidation reactor 10 walls are metal, add magnetic field 5 on reactor 10 sewage inlets 1 pipeline, because the sewage inlet flow velocity is bigger, the frequency sweep magnetic field effect that adopts sweep frequency power source and power winding to provide is better; Fixed installation ultrasonic transducer 9 provides ultrasonic wave to enter reactor on reactor 10 outside wall surface; On reactor 10 walls transparent window is arranged, reactor is installed ultraviolet source 8 outward, and the irradiation reactor provides light wave.During work, hydrogen peroxide enters from oxidant inlet 2, in mixing tank 4, mix with sewage through storage tank 3, enter reactor through frequency sweep magnetic field 5 again, the ozone that ozonizer 6 is confessed, enter reactor 10 with check valve and bubbling sparger 7, light wave enters reactor by window, ultrasonic wave respectively by ultrasonic transducer, and reacted liquid phase and ozone tail gas enter separator 11, and tail gas is handled through ozone breaker 12 again, from exhaust port 13 dischargings, treated water is through water outlet 14 extraction systems then.According to the reaction needs, also can with treated water all or part of through the pump circulator to sewage inlet, also can select multiple-chamber reactor as shown in Figure 2 for use.

Cooperating type advanced oxidation reaction unit is built-in multicell structure as shown in Figure 2, adds magnetic field 5 on reactor 10 sewage inlets 1 pipeline, and it is simply non-maintaining to adopt permanent magnetic field to install; Ultrasonic transducer 9 sealings also are fixed on reactor 10 inner-wall surfaces; The printing opacity sleeve pipe is housed in the reactor 10, ultraviolet source 8 is housed in the sleeve pipe.Sewage enters reactor after magnetic field treatment, ozone adds through sparger 7, and ultrasonic wave is imported by light source and sleeve pipe through the ultrasonic transducer light wave, and under the ultrasonic synergy that involves light wave, sewage is oxidized, degraded, mineralising.After the multicell series connection is handled, meet the requirements of processing horizontal, treated water goes to store through water outlet 14, and ozone tail gas truncates gas disposal after exhaust port 13 discharges.
