Accompanying drawing explanation
Fig. 1 is embodiments of the invention schematic diagram;
In figure, 1 is factory building, and 2 is substrate, and 3 is photocatalysis thin film layer, and 4 is transport pipe, and 5 is water distributor fog nozzle, and 6 is water pump.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
See Fig. 1, solar energy photocatalytic degradation of sewage system, comprise the substrate 2 be installed in factory building 1 inclined roof, and at least one deck is arranged on the photocatalysis thin film layer 3 of upper surface of base plate, and the transport pipe 4 of conveying sewage, transport pipe is provided with the water distributor fog nozzle 5 be sprayed onto by sewage on photocatalysis thin film layer, the water distributor fog nozzle sewage be sprayed onto on photocatalysis thin film layer forms one deck liquid film, and the thickness of liquid film is between 100 microns-500 microns.During concrete enforcement, substrate adopts glass board material to be laid on factory building or house roof, and such substrate shape can have a certain degree and better receive the irradiation of sunlight, and transport pipe is communicated with a water pump 6, carries out active like this carry by water pump to sewage;
Wherein, photocatalysis thin film layer is photocatalytic nanometer TiO
2layer, photocatalytic nanometer TiO
2particle diameter at 23nm-28nm.In concrete enforcement, photocatalytic nanometer TiO
2particle diameter can be 25nm.Use spraying method by photocatalytic nanometer TiO
2the solvent of particle is laid on substrate, and concrete selection high-efficient atomizing spray gun, utilizes air pressure pump that solvent is evenly sprayed on upper surface of base plate, make TiO at UV light irradiates 2 hours
2solidification; Wherein, multilayer can be sprayed, to increase the density of catalytic film layer, due to photocatalytic nanometer TiO
2containing a certain proportion of glue crosslinking agent in the solvent of particle, contribute to firmly adhering to.
The present invention utilizes natural diffuse-reflectance sunlight, also can keep certain reaction efficiency at the cloudy day, is specially adapted to the sewage disposal of dye molecule and other hardly degraded organic substances.Sewage through process of the present invention can adopt receiving tank to carry out collecting with his use, can also couple together, reach the landscape utilization of waste water, beautify plant area with the view such as artificial hillock, waterfall.The present invention can also use heavy metal to mix up type photocatalyst, can improve ultraviolet-responsive region, increases sunlight utilization ratio; Adopt large-scale vacuum sputter TiO on plated surface on the glass substrate
