Abstract
The invention relates to a high-treatment-capacity reactor for degrading electrodeless ultraviolet light catalytic wastewater, belonging to the technical field of wastewater treatment. The existing electrodeless ultraviolet light catalytic degradation technology for the organic pollutant-containing industrial wastewater has the problem of the useless dissipation of the energy since a mass of the microwave energy is absorbed by the wastewater body, and the problem of the less treatment capacity of the single-jar wastewater of the reactor. In order to solve the problems, an electrodeless ultraviolet lamp is arranged in a cage-shaped nonopaque microwave restraining device made from metal material, the microwave is guided into the microwave restraining device to be restrained, the useless loss of the microwave can be stopped, and in the structure, an ultraviolet-permeable quartz tube for gas-liquid isolation is arranged at a structure position between the microwave restraining device and wastewater body. On the basis of the structure, the great expansion of the design volume of the reactor can be realized due to the design volume for greatly expanding a microwave irradiation-free airspace in the reactor, so that the single-jar wastewater treatment quantity of the reactor can be greatly improved.
Description
Technical field
The present invention relates to a kind of electrodeless ultraviolet light catalysis waste water degraded and use the high throughput reactor drum, belong to the C02F technical field of waste water processing.
Background technology
Microwave and photo catalysis degradation treatment technology, effectively to the innoxious process for treating that contains the organic pollutant trade effluent, development in recent years is swift and violent as a kind of.
About the microwave and photo catalysis degradation technique,, can referring to publication number the one Chinese patent application case of CN102260003A as an example.
This publication number is the one Chinese patent application case of CN102260003A; Be with microwave as excitaton source, excite electrodeless uv lamp emitted in ultraviolet line, be mixed with the suspension liquid of photocatalyst titanium oxide in liquid internal irradiation; This electrodeless uv lamp is shrouded by silica tube to be protected; Have pneumatic pump continue to inject air to this silica tube inner chamber, the air that is overflowed by quartzy chamber is via pipeline and the micro porous aeration head UNICOM that is positioned at reactor bottom, and the lower zone of this inside reactor is the aeration zone; The upper area of this inside reactor is the microwave and photo catalysis reaction zone; This scheme is also with the built-in membrane separation assemblies of reactor drum, carries the water of analysing after the purification, and realizes that with this membrane separation assemblies holding back again of photocatalyst titanium dioxide fine particles use; This scheme is also set up dividing plate between electrodeless ultraviolet light source and membrane separation assemblies, be used to prevent the radiation injury of ultraviolet ray to the membrane separation assemblies of organic matter; Feed the air of inside reactor; Part is participated in the photocatalytic degradation reaction that relies on photocatalyst titanium oxide directly; Some air; Under the direct irradiation of UV-light, generate a certain amount of ozone, the ozone of this generation is also being brought into play the direct oxidative degradation that is directed against organic pollutant certainly.
This publication number is that the one Chinese patent application case of CN102260003A has undoubtedly played very important pushing effect for the progress of microwave and photo catalysis waste water degradation technique, and its research staff is admirable in this field institute unfolded work.
Based on the meaning of sincere admiration, and, the common striving direction, what will talk below us is problem.
We know that itself also can absorb the energy of microwave liquid water body, and itself temperature-rise effect of the liquid water body that causes being processed; And this temperature-rise effect of following wastewater treatment process and occurring but is not the situation that we expected, in other words; Microwave energy from magnetron is not used to excite electrodeless uv lamp fully, and has quite a few should only be used to excite the microwave energy of electrodeless uv lamp to be dissipated in described temperature-rise effect, and the temperature-rise effect that this kind is not fond of has caused unnecessary microwave energy to waste; In view of above-mentioned publication number is the apparatus structure scheme that the one Chinese patent application case of CN102260003A is showed, its rational approach can only be to reduce the purpose that single jar of processing capacity is reached the unnecessary dissipation of reduction microwave in other words through the volume that reduces the microwave and photo catalysis reactor drum; About this point, the clear expression in this its embodiment of CN102260003A application case about the whole suitable size of this apparatus structure, what its expressed preferred size was corresponding is exactly a device that profile is very little; So, thus, the distance of reactor wall and microwave radiation source is little; The wastewater flow rate that contacts with microwave is little, and waste water institute microwave energy absorbed is also little relatively, with it accordingly; Single jar wastewater treatment capacity is therefore also little, and more particularly, the pairing internal capacity of device suitable size expressed in the embodiment is 40 liters; Also be that single jar of wastewater treatment capacity is 40 liters, promptly 0.04 cube, in other words; It is once a complete set of, substantial length of operation has only solved 0.04 cubical trade effluent, so, just need carry out the repetition of being operated to the complete set of tail by head many times; Adding up of its treatment capacity just has plant-scale meaning; So to say, just individual analogy roughly, single jar of corresponding 0.04 cube of such wastewater treatment capacity of its preferred structure general size of this case; Need repetition 1000 times by a complete set, the substantial length of operation of head to tail; Its accumulation amount, just can reach 40 cubes such one have industrial level wastewater treatment capacity, so excessively loaded down with trivial details repetitive operation will cause the serious waste of human and material resources; It is thus clear that this kind may not be fully up to expectations by its actual waste water degradation treatment efficient of scheme that CN102260003A showed.Therefore; How not cause more microwave energy wastes or to reduce under the prerequisite of microwave energy waste; Increase single jar of wastewater treatment capacity; Reducing the unnecessary too many by the repetitive operation number of times of head to tail of this intermittent type wastewater treatment equipment, improve its waste water treatment efficiency, is a significant technical problem that merits attention.
