Description
Technical field
The invention belongs to technical field of sewage in environment protection, be specifically related to a kind of device for the treatment of organic waste water.
Background technology
Traditional water treatment method efficiency is low, cost is high, there is secondary pollution problems, the solution that waste water control can not get always.Development and the application of nanotechnology probably thoroughly solve this difficult problem.Photochemistry and photocatalytic oxidation are the high-level oxidation technologies that research is more at present.So-called light-catalyzed reaction, the chemical reaction carried out under the effect of light exactly.Photochemical reaction needs the electromagnetic radiation of molecular absorption specific wavelength, is excited to produce molecular-excited state, then chemical reaction can occur and generate new material, or becomes the middle chemical product causing thermal response.Photochemically reactive activation energy derives from the energy of photon, and in the utilization of sun power, photoelectric conversion and photochemical transformation are very active research fields always.Research shows, have multiple semiconductor nano material to process multiple toxic compounds at present, can by the hydro carbons in water, halohydrocarbon, acid, tensio-active agent, dyestuff, itrogenous organic substance, organic phosphorous insecticide, wood preservative and fuel wet goods soon complete oxidation be CO
2, H
2the innoxious substances such as O.But up to the present nano-photocatalyst material technology is used widely not yet in wastewater treatment, mainly because nano particle separation difficulty, the not simple treatment facility be suitable for.
By nano particle in carrier surface load, the problem of particle separation can be solved.But time load has the carrier of nano particle to be soaked in water, the solution that exciting light must be transmitted through thicker (often more than several centimetres) just can be irradiated on catalyzer.And in fact, no matter be in ultraviolet region or visible region, organic solution (being especially with look organic wastewater) all can have photoabsorption in various degree, this will certainly cause exciting light light loss in various degree, the light intensity arriving catalyst surface is declined, thus the productive rate in light induced electron and hole is declined, finally make the degradation efficiency of pollutent reduce.
The ozone that ozonizer produces, is spread in pending water by air-water contact equipment, normally adopts microporous diffuser, bubble tower or injector, turbomixer etc.It is more difficult that the utilization ratio of ozone will reach more than 90%, if insufficient utilization, residual ozone also needs to continue process.
Summary of the invention
The object of the present invention is to provide a kind of photocatalysis apparatus for the treatment of organic waste water, can luminous energy be made full use of, greatly improve photocatalysis efficiency.
The technical solution used in the present invention is: the present invention has the square horizontal glass chamber that multilayer is arranged in parallel up and down, the side of neighbouring two horizontal glass chambers is connected by a square vertical glass chamber 7 and is communicated with the closed U-shaped square tube road of composition one, all U-shaped square tube road head and the tail are closed and are connected and are communicated with, have outlet in the left side of most last layer horizontal glass chamber, the right side of basecoat horizontal glass chamber has import; Gap location between every two-layer horizontal glass chamber arranges the LED flat lamp of a level, several aeration heads 3 are provided with in every layer of horizontal glass chamber, the area load of each aeration head has silver phosphate catalyst, and all aeration heads are interconnected by open tube, pass into ozone gas in open tube.
Several aeration heads in every layer of horizontal glass chamber are the array layout of level, and open tube passes one by one and is connected to each aeration head, and have an aperture in each junction, ozone gas is diffused out by each aeration head.
The advantage that the present invention compared with prior art has is: (1) optical efficiency improves greatly; (2) ozone oxidation and photocatalysis treatment are combined together, associated treatment successful; (3) device volume is little, compact construction; (4) effectively can utilize ozone, repeatedly turn back through U-shaped square tube road, increase gas-liquid transfer efficiency.
