Description
Technical field
Patent of the present invention is to adopt the effect of nanometer porous titanium oxide film light catalyzed oxidation; For farm crop provide the method for the neutral activated water of a kind of fertilising of watering (adding 1 ‰ N, P, K), especially this method relates to the crisscross bamboo shoots shape bur technology of its Glass tubing inwall.
Background technology
At present, the commodity of domestic and international market sale activated water are more: water glass, hydrophone for kitchen use are arranged, also be useful on aquaculture, farm crop, tap water, after shave lotion etc., they mostly adopt most advanced world " photochemical catalysis 1. 2. " technology.Nano-titanium oxide is one of N type photosemiconductor material that has photo-catalysis function, and under the irradiation of light, the titania surface that is stimulated produces electronics and electric hole, follows the water oxidation that titania surface will be adhered in electric hole, and changes this water into hydroxyl free radical; And electronics makes it become ultra oxidative ionic the hydrogen reduction in the water.Hydroxyl free radical and ultra oxidative ionic decompose organic cpds on the titania surface and part inorganics, degrade with oxidations; Heavy metal ion is reduced into stable and precipitable MOX; Kill bacterium, virus, parasite and algae gemma in the water; Oxygen is emitted in deodorizing simultaneously, purifies demineralized water.
The nano-titanium oxide photocatalytic oxidation has the branch of power, and main influence has: one of which, and relevant with wavelength, intensity, the battle-sight range of excitation line, the wavelength of light is short, power is big, battle-sight range is near, and the effect of photochemical catalytic oxidation is just strong more, otherwise more.In nano-titanium oxide, mix, light can expand to visible light 320nm from UV-light 254nm commonly used, even to half-light (unglazed), but photocatalytic oxidation also by by force to a little less than, vibrate and devices such as deodorizing remedy so add in some activated water apparatus.Light in water in geometricprogression successively decrease, ultraviolet effective radius is 10cm, other light is littler.Its two, with nano-titanium oxide smear carrier related, carrier has stainless steel, glass, micropore ceramics or the like.Stainless steel is when 500 ℃ of crystallization titanium oxide, and the steel interior element is prone to diffuse into the speed that influences photochemical catalytic oxidation in the titanium oxide, and surface easy oxidation easy to change is prone to pollute, and photocatalytic oxidation dies down gradually; Glass is coated with the nano-titanium oxide film, controllable film thickness system, and indeformable at 500 ℃ of crystallization titanium oxide, strong adhesion has self-cleaning function, does not quite but be prone to broken, specific surface area; Micropore ceramics is without light, and a little less than the photocatalytic oxidation, it remedies with big specific surface area and other functional device of interpolation, but pollution is prone to stop up.Its three, relevant with photocatalysis oxidation reaction speed, need to hinder the simple composite in photic electronics and electric hole.Can in reaction system, add oxygenant trapped electrons such as ydrogen peroxide 50, persulphate, make it become ultra oxidative ionic, also can in nano-titanium oxide, add the iron ion of divalent, 3 valencys or the cupric ion of divalent, trapped electron on different being with.
" π water " device 3.; This device is Cylinder, and the work core of garden shape is that 8 plies are become one, wherein 6 layers " π water " micropore ceramics and 2 stratas knot particle; No light source; Above prior art problems is: otherwise the function refinement, or regularly change core, because their method all belongs to the physical mechanical method field." π water ", adds other function core and remedies a little less than this device photocatalytic oxidation though technology relates to the nano-catalytic method, and easy pollution is prone to again stop up, and can not unpick and wash to cause losing efficacy, or core body just changes after always aquifer yield reached 60 tons, caused working cost high.This device adopts the micropore ceramics core body of function refinement, only adapts to the high-quality water quality of Japan, is not suitable for the water quality of China especially, promotes difficulty.
