Abstract
The invention discloses a multi-stage bubbling oxidizing tower-type sewage treatment reactor which comprises UV lamps, a dosing pump, partition boards, and a reaction zone between two layers of partition boards, wherein the UV lamps are made of quartz tubes, are translucent, and are mounted on staggered partition boards correspondingly; a hydrogen peroxide solution is added in the reaction zone; an aeration device is arranged at the bottom of the reactor; air and ozone are led into the reactor. Therefore, sewage to be treated through the synergistic effects of the UV lamps, hydrogen peroxide and ozone while entering the reactor from the bottom of the reactor, and a large proportion of organic matters are oxidized and decomposed. As the three decontamination methods are combined, the organic wastewater treatment effect is greatly improved, secondary pollution is avoided, the treatment efficiency is improved, and the cost is reduced. In the aspect of treating high-salt content high-concentration organic waste water with difficulty in degradation, such as printing and dyeing waste water, oil-bearing waste water, pesticide waste water and other high-salt content high-concentration chemical waste water, the efficiency is very high.
Description
Technical field
The invention belongs to environmental protection and field of energy-saving technology, particularly the tower sewage-treating reactor of a kind of multistage bubbling oxidation.
Background technology
It is one of main Environmental Problems of facing of current China that water pollutes.Discharged volume of industrial waste water is larger, and take again supersalinity and high concentrated organic wastewater as main.Supersalinity high concentrated organic wastewater environmental pollution degree is large, and is not easy to process, and is one of difficult problem in domestic and international environmental protection research field, so its purifying treatment more and more receives people's concern.The supersalinity high concentrated organic wastewater generally refers to the higher waste water of COD that the chemical industries such as printing and dyeing, agricultural chemicals are discharged, organic substance toxicity in these waste water is large, be difficult to biological degradation, intractability is large, complex treatment process, invest highly, and running cost is high, if directly discharge, can cause severe contamination to environment.The treatment process that water pollutes at present has Physical, chemical method and biological process etc., but these method processing costs are higher, the treatment scheme complexity, and can not remove salt and high-enriched organics simultaneously, treatment effect is not good.
Summary of the invention
The present invention is directed to the deficiency of above-mentioned technology, provide a kind of multistage bubbling oxidation tower sewage-treating reactor, comprise UV lamp, dividing plate and be positioned at the reaction zone between two-layer dividing plate, it is characterized in that: the UV lamp is arranged in the cylindrical area of dividing plate, every alternating floor dividing plate all is equipped with the UV lamp, dog-house is positioned in the middle of two-layer dividing plate, and described device bottom has sewage water inlet pipe, and the sewage rising pipe is arranged at the equipment top.
In addition, the tower sewage-treating reactor of a kind of multistage bubbling oxidation of the present invention, described UV lamp is the normal pressure mercury lamp, power is 6～40W.Described cylindrical area is formed by the quartzy material manufacture of printing opacity.Described dividing plate is Perforated clapboard, by the synthetic materials manufacture.Described dog-house adds the superoxol of mass concentration 30%.Described device bottom has aerating apparatus.
The invention has the beneficial effects as follows:
1. the present invention is under the bubble tower type reaction tank, has realized the synergy of superoxol, decontamination ozone decontaminating and UV decontamination, can improve the treatment effect of sewage.
2. sewage treatment process of the present invention combines with other sewage treatment process, can make sewage treatment process reach efficient low-consume.
3. treatment process effect stability of the present invention, the COD clearance is higher, and the influence factor be subject to is few.
In a word, the present invention can be large as far as possible increase sewage and contact area and the time of hydrogen peroxide and ozone, take full advantage of the synergy of superoxol and ozone solution and UV, thereby solve the existing existing problem of sewage water treatment method, improve the processing efficiency of organic waste water, improved wastewater treatment efficiency.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the tower sewage-treating reactor of a kind of multistage bubbling oxidation of the present invention is described further
The sectional view of the tower sewage-treating reactor of multistage bubbling oxidation that Fig. 1 is embodiment one
Embodiment
Below by accompanying drawing, example of the present invention is described in detail:
Decontamination principle of the present invention is as described below:
Hydrogen peroxide is the oxygenant that a kind of oxidisability is very strong, the most pollution substance of energy oxidation, but oxidation efficiency own is not high.The UV lamp also can some pollutents of catalytic decomposition, but speed of response is slow.There is synergistic effect in UV to Catalytic Decomposition of Hydrogen Peroxide, and hydrogen peroxide can produce HO under the UV katalysis, and it is a kind of strong oxidizing property material, and comparatively fast the oxygenolysis organism, strengthen oxidation efficiency, improves treatment effect.Because in supersalinity and high concentrated organic wastewater, pollution substance is not easy to be degraded, so these two kinds for the treatment of processs are combined, just can improve the processing efficiency of organic waste water.
In order to reach above-mentioned effect, the present invention adopts following structure:
The sectional view of the tower sewage-treating reactor of multistage bubbling oxidation that Fig. 1 is embodiment one
As shown in Figure 1, the tower sewage-treating reactor of multistage bubbling oxidation of embodiment one is comprised of UV lamp 1, dividing plate 2 and the reaction zone 10 that is positioned at 2, two-layer dividing plate, wherein, UV lamp 1 is arranged in the cylindrical area of dividing plate 2, every alternating floor dividing plate 2 all is equipped with UV lamp 1, UV lamp 1 is the normal pressure mercury lamp, and power is 40W.Cylindrical area is formed by the quartzy material manufacture of printing opacity, and ultraviolet ray can be penetrated in a large number.Dividing plate 2 is made by synthetic materials.Dog-house 8 is positioned in the middle of two-layer dividing plate 2, at every layer region, reaction zone 10 is set, and adds the superoxol of mass concentration 30% from dog-house 8, and superoxol produces a large amount of HO under UV catalysis, and the most organic substance of energy oxidation, improved speed of reaction.Reactor bottom is provided with aerating apparatus, by inlet pipe 5, passes into air and ozone, for organic oxidation provides part oxygen source and another kind of oxygenant, makes organic pollutant thoroughly be degraded to CO
2And H
2O.Reactor bottom has sewage water inlet pipe 4, and sewage rising pipe 6 is arranged at the equipment top.Sewage enters from reactor bottom, can be subject to the synergy of UV and hydrogen peroxide through every layer region the time simultaneously.Because hydrogen peroxide can produce HO strong oxidizing property material under the UV effect, so majority of organic pollutants matter is oxidized to micromolecular material as CO
2And H
2O.It is little that the method is processed the secondary waste water pollution, can utilize the synergy of UV lamp 1 and hydrogen peroxide to be processed sewage simultaneously, improved the treatment effect of organic waste water, improved processing efficiency.
