Description
Technical field
This patent invention relates to continuous high-efficient sewage and waste water COD treatment unit, refers in particular to a kind of continuous high-efficient device for treating sewage and waste water COD by photocatalysis
Background technology
National big or small sewage work spreads all over the country more than 1500 families at present, is subjected to drop into investment deeply greatly, the puzzlement that maintenance and improvement time are long always; Sewage and waste water is mainly by salt, chlorine, bacterium, CODC takes existing COD, and existing national regulation is at 160-280, from state sewage emission standard gap is arranged, existing country again mandatory requirement all waste water controls must go another step the end of the year in 2009, like this with the existing method waste water COD of disposing of sewage, dropping into can be bigger, and all kinds of activators are doubted solid agent, organic liquor, in the improvement cycle, treatment cost artificially drops into all kinds of chemical toxicant toxicity and also just rises especially in the water after administering.So a kind of high efficiency, low cost of simple possible, the gordian technique of administering sewage and waste water COD just becomes human survival, resource, ecology, the basis of Economic development.Up to the present state-of-the-art big flow sewage and waste water COD treatment process technology is all apparent in addition to be main, and to all not having processing technological flow and technology efficiently under the liquid solubilised state of the COD of main environmental pollution.Waste water control technology now commonly used, biochemistry pool, blast pool is handled and the state-of-the-art ozone that adds, and adds the pure oxygen technology all because of the cost height, the cycle is long, puzzlement such as operation easier is big not before.
By in the waste water control: the biochemistry pool method, the aeration tank method, the ozone method, the pure oxygen method, the peptizer method, the precipitator method, absorbent charcoal method, cascade filtration, or the like the comparison of method.
Up to the present do not have as yet in pair sewage and waste water COD improvement and embody at flow concentration, time, the treatment process and the technical scheme of aspect advantage such as efficient, in fact the real governance process of sewage and waste water COD is exactly all kinds of active organic solutions in the water, and solvent and all kinds of active substance are dispeled process.
Summary of the invention
The problem that apparatus of the present invention solved overcomes existence deficiency in the above present waste water control technology exactly, has both reached big flow, big concentration, the high purification, high-level efficiency provides a kind of high-efficiency device for treating sewage and waste water COD by photocatalysis, it is short to reach the improvement time, and the photochemical catalysis contact surface strengthens to be accelerated.Photocatalytic surfaces activates unobstructed, realizes quick improvement of the three-dimensional segmentation of sewage and waste water COD.
This a kind of high-efficiency device for treating sewage and waste water COD by photocatalysis, it is characterized in that: comprise a casing, described casing front portion is provided with water-in, the rear portion is provided with water outlet, be provided with the some of some ultraviolet lamp tubes and same horizontal Tile setting in the described casing side by side and scribble the rotatable rotating cylinder of column that titanium dioxide optical catalyst net sheet setting certain intervals is made up of the center stack by multilayer.
Being arranged side by side some ultraviolet lamp tubes in the described casing, is that the low coverage irradiation activates the photocatalytic particle on rotatable rotating cylinder net sheet and the water stream channel, accelerates to strengthen the catalyzed reaction ability.
Be horizontally disposed with in the described casing and somely scribble the rotatable rotating cylinder of column that titanium dioxide optical catalyst net and sheet are formed by multilayer, be used to roll up the catalyst reaction area, the segmentation sewage and waste water repeatedly repeats contact and administers sewage and waste water, improves catalysis treatment ability and efficient.
Rotate when being horizontally disposed with some rotatable rotating cylinders in the described casing, guarantee that flow velocity and the purification treatment ability that oxidation is administered administered and repeated to segment again in the segmentation of sewage disposal.
The mirror reflective layer that described casing internal box top is provided with is for the collection tank internal reflection, the ultraviolet ray of scattering, and reuse, increase ultraviolet utilization ratio and improve the reaction Governance Ability.
Described casing internal box top can be to move and is provided with, and when adopting sunlight, save energy improve plant factor in a large number.
This patent contrive equipment is useful for the improvement of various sewage and waste water CODs and the advanced treatment of water technology, this device has adopted photochemical catalysis high-efficiency and continuous activation technique and internal reflection technique to combine, the sewage and waste water segmentation adds the three-dimensional contact of repetition Treatment Design, embodying a concentrated reflection of out decomposition and sterilization kills mattress and becomes one, realized the industrialization of the Effictive nuisancelless technology of photocatalysis technology, pollutent resolves into the non-secondary pollution of carbonic acid gas and water.This device simple in structure, maintenance cost is low, be suitable for sewage and waste water COD before, in, post-processed, with existing all kinds of sewage and waste water treatment facilities in conjunction with processing, all be convenient and easy, be designed to full-automatic operation, can operate without the special messenger, also can be designed to the two structures of utilizing of electric energy and sun power, that is the ideal good technique device of benefiting the universe especially.
Description of drawings
Fig. 1 is the structural representation of this patent invention.
Embodiment
Invention is further described to this patent below by accompanying drawing.
As shown in Figure 1, a kind of high efficiency photocatalysis is administered the sewage and waste water device, comprises a casing 1, and described casing 1 front portion is provided with water-in 2, and the rear portion is provided with water outlet 3; In casing 1, laterally be provided with some quartz burners 4 side by side, also be provided with water level assigned switch 11 on the case spare 1, guarantee to administer the wastewater level height; Quartz burner 4 is installed by last lower fixed frame 5; Be installed in the casing 1 by anchor 7 with quartz burner 4 horizontal some rotatable rotating cylinders 6, some rotatable rotating cylinders 6 are driven by wheelwork 8; Rotatable rotating cylinder 6 is arranged overlapping composition column by net sheet 10 at certain intervals by the center stack; Casing 1 top is fixed with mirror reflective layer 9, and casing 1 its inwall is coated with titanium dioxide optical catalyst; In fact, rotatable rotating cylinder 6 quartz burners 4 also can vertically be located in the casing 1, can achieve the goal equally.
