Description
Technical field
The present invention relates to obtain the UV water treatment equipment of a plurality of different quality grades.
Background technology
Ultraviolet ray is the hertzian wave of a kind of wavelength in the scope of 100～400nm.Handle in the water treatment up and down of a large amount of water at needs, use mercuryvapour lamp as ultraviolet source cheaply.Enclosing in seeing through the ultraviolet quartz glass tube of mercuryvapour lamp has mercury vapour, under the effect of the vapour pressure in the quartz glass tube that lamp is lit a lamp, generates the wavelength difference.The lamp of vapour pressure below 100Pa is called Cooper-Hewitt lamp, and generating wavelength is the monochromatic ultraviolet line of 254nm.Vapour pressure is called middle medium pressure mercury lamp at the lamp of 50～300kPa, and generating with 365nm is the light of predominant wavelength and the wavelength wide region from the ultraviolet ray below the 200nm to visible light.
In water treatment up and down, ultraviolet ray is mainly used in deactivation and the organic oxygenolysis of microorganism.The deactivation of so-called microorganism is meant the state of microorganism forfeiture fecundity, infection ability isoreactivity.The DNA of microorganism shows the peak value that absorbs near wavelength 260nm, if absorb near the ultraviolet ray this wavelength, then adjacent thymus pyrimidine (thymine) is Dimerized in the DNA chain, can not carry out duplicating of DNA, bacteria inactivation rate.
In organic oxygenolysis, though the situation of only decomposing to the organism irradiation ultraviolet radiation is also arranged, but the main light-catalyzed reaction that utilizes ultraviolet ray and photocatalyst, perhaps based on the promotes oxidn reaction of ultraviolet ray with ozone or superoxol, perhaps ultraviolet ray is decomposed with the light-catalyzed reaction of photocatalyst and ozone or superoxol etc. and the reaction after the combination of promotes oxidn reacting phase.
In light-catalyzed reaction, if illumination wavelength is at ultraviolet ray below the 400nm or the visible light more than the 400nm on the photocatalysts such as titanium oxide in being immersed in processed water, then water is decomposed and generates hydroxide radical free radical (hydroxy-radical).Free radical (radical) has strong oxidizing property, with oxidation operation, decomposition on every side.Absorbable long wavelength is by the kind decision of photocatalyst.
The ozone or the hydrogen peroxide that in the promotes oxidn reaction, use, owing to itself have oxidisability, so the oxidized decomposition of the organism in the processed water.In the promotes oxidn reaction, utilize ultraviolet ray to decompose ozone or the hydrogen peroxide that adds directly or indirectly.Under the situation of directly decomposing, the ultraviolet ray below processed water illumination wavelength 300nm.The ultraviolet light degradation ozone or the hydrogen peroxide of this frequency band generate the hydroxide radical free radical.Under the situation of decomposing indirectly, in processed water, sneak into photocatalyst.The not only ultraviolet ray of absorbing wavelength below 300nm of photocatalyst, also ultraviolet ray and the visible light of absorbing wavelength more than 300nm generates the hydroxide radical free radical.Hydroxide radical free radical ozone decomposition or hydrogen peroxide further generate the hydroxide radical free radical.Because the hydroxide radical free radical has than ozone, oxidisability that hydrogen peroxide is stronger,, organic oxidation and decomposition have been promoted so compare with the situation of independent use ozone or hydrogen peroxide.
Use under the situation of Cooper-Hewitt lamp in the deactivation of microorganism or organic oxygenolysis, the ultraviolet ray of generation is absorbed well by DNA, ozone or hydrogen peroxide.Therefore, the reaction of deactivation or promotes oxidn can be carried out expeditiously, the needed electric weight of water treatment can be reduced.On the other hand, in use under the situation of medium pressure mercury lamp, though the efficient of deactivation or promotes oxidn reaction is not high, because the ultraviolet work output that the per unit lamp body amasss is big, reduced the platform number of the needed lamp of water treatment, so have the advantage that device can miniaturization.
As such water treatment device, in [non-patent literature 1], [patent documentation 1], [patent documentation 2], disclose.
[non-patent literature 1] described water treatment device is the device that makes bacteria inactivation rate, is the structure of dipping UV-lamp in the groove of drum.[patent documentation 1] described water treatment device is the organic device of oxygenolysis, floods UV-lamp in the groove of drum, injects ozone bubbles in same groove.[patent documentation 2] described water treatment device, in internal configuration the processed liquid of collecting post's requirement in the treatment tank of UV-lamp, bottom side in treatment tank carries out aeration (aeration) and supply in turn with ozone and Air mixing gas, stir processed liquid and it is contacted with described mixed gas, impurity is carried out redox, sterilization.
The spout for the treatment of water all is one in any one device, the exposure intensity by changing ultraviolet source or handle flow etc., the control water quality treatment.That is, only can obtain a kind for the treatment of water of water quality from a device.

But, for example need sewage discharge water and reuse water to require the different processing of water quality like that sometimes in sewage disposal department.
For reuse water,, also have to require on this basis up to making organism such as odorous substance or chromatic(ity)component reduce just passable situation as long as the situation that bacteria inactivation rate is got final product is arranged.As long as under the situation that bacteria inactivation rate is got final product, the benchmark ratio sewage discharge water benchmark strictness of reuse water.For example, reuse water requires intestinal bacteria not detect/100mL, and sewage discharge water requires 3000/mL of coliform.
Therefore, if will be by the water after the benchmark processing of reuse water as sewage discharge, the water quality of discharging point of destination improves, and then handles surplus as sewage discharge water on the contrary, has the problem of the running cost increase of treatment plant.In order to use prior art more effectively to carry out water treatment, need a plurality of sewage discharge water different device of using with reuse water, exist the area change to be set greatly, the problem that cost also increases.
In addition, about requiring to reduce organic reuse water, the water quality difference of itself and sewage discharge water is bigger.This be because, in general for reducing organism, need be than making the more ultraviolet irradiation amount of volume of bacteria inactivation rate.In the reuse water of irradiation ultraviolet radiation till reducing organism, can fully reach the benchmark of bacteria inactivation rate.Like this, when the reuse water that will implement to reduce treatment of organic matters of organic during,, there is as the superfluous processing of sewage discharge water the problem of the running cost increase of treatment plant though the water quality of discharging point of destination becomes better as sewage discharge.In this case, carry out water treatment, also need a plurality of sewage discharge water different device of using with reuse water, exist the area change to be set greatly, the problem that cost also increases in order more effectively to use prior art.
