Abstract
The utility model relates to a field-aided semiconductor photocatalysis waste water treatment device comprising a box body. The utility model is characterized in that a plurality of working units which are composed of ultraviolet lamps, quartz tubes and metal nets are arranged in a box; the ultraviolet lamps are fixed in the quartz tubes; titanium dioxide coating layers are arranged on the outer walls of the quartz tubes; the metal nets are fixed outside the quartz tubes; one end of each quartz tube is connected to the positive pole of a power supply; the metal nets are connected to the negative pole of the power supply; both end heads of each quartz tube penetrate through the box wall so as to be sealed together with the box wall. The structure of the utility model enables ultraviolet light to directly act on titanium dioxide basically without light loss. Photoproduction electrons are separated from photoproduction positive holes by an electric field so that the recombinationchance between the photoproduction electrons and the photoproduction positive holes is decreased, thereby, the reaction rate is greatly increased.
Description
Technical field
The utility model belongs to sewage treatment equipment.
Semi-conductor titanium dioxide is under wavelength shines less than 387 nano-ultraviolet lights, on conduction band and valence band, produce a large amount of light induced electrons and photohole, be adsorbed on dissolved oxygen on the titanium dioxide, water molecules etc. and act on mutually, produce the extremely strong free radicals of oxidisability such as hydroxyl free radical with the electron hole.These free radicals can decompose multiple organism, bacterium and virus.Therefore, at present titanium dioxide is usually used in handling various organic waste waters, and more advanced apparatus structure comprises a container, on the inwall of the container that the titanium dioxide paster is pasted, in the bottom of container ultraviolet lamp is installed.Major part was absorbed by waste water when the UV-light of this device was transmitted, and had reduced the productive rate of free radical, and treatment effect is bad.
Summary of the invention
The purpose of this utility model is to provide the higher field of a kind of processing efficiency to help the conductor photocatalysis waste water treater, as shown in drawings, the utility model comprises a casing, water-in and water outlet are arranged on the casing, processed waste water flows through in casing by water-in and posticum, it is characterized in that in chest, being provided with several by ultraviolet lamp, the working cell that silica tube and wire netting are formed, ultraviolet lamp is fixed in the silica tube, on the silica tube outer wall coating of titanium dioxide is arranged, wire netting is fixed on outside the silica tube, one end of silica tube connects the positive pole of power supply, wire netting connects the negative pole of power supply, constitutes an electric field between wire netting and the silica tube, and the two ends of silica tube is passed tank wall and also and between tank wall sealed, the terminal stud of ultraviolet lamp is exposed at outside the casing, is a sealing member in the casing.Structure of the present utility model directly acts on UV-light does not have light loss substantially on the titanium dioxide, electric field separates light induced electron and photohole reduce the two compounding machine meeting, make speed of reaction increase substantially, and experimental results show that comparable prior art improves more than ten times.
Description of drawings
Accompanying drawing is the utility model structural representation.Legend: 1, wire netting; 2, silica tube; 3, ultraviolet lamp; 4, instrument panel.
Embodiment
As shown in drawings, ultraviolet lamp is fixed in the silica tube by support, and the silica tube two ends are fixed on two end faces of casing, interfix between the wire netting.50 millimeters of silica tube diameters, long 600 millimeters, thick 50 nanometers of silica tube outer wall TiO 2 coating film.80 millimeters of wire netting diameters, long 550 millimeters.Long 1000 millimeters of casing, wide 500 millimeters, high 500 millimeters, coordinate 50 working cells in the casing.Instrument panel of casing external fixation is fixed with voltmeter, reometer and working cell pilot lamp on the instrument panel.
