Abstract
The utility model relates to an ozone-ultraviolet ray photocatalysis water treating equipment, which takes advantage of the ozone-ultraviolet ray photocatalysis technology to treat the sewage with difficult degradable organics. An intake of gas-liquid mixing pump is connected to outlets of an intake pipe and an ozone generator; an outlet of gas-liquid mixing pump is connected to an ozone contact reaction can, while an ultraviolet ray catalytic reactor is arranged between the gas-liquid mixing pump and the ozone contact reaction can; an intake of plunger pump is connected to the intake pipe, and an outlet of plunger pump is directly connected to the ozone contact reaction can. The ozone contact reaction can is pressed by the plunger pump to make ozone dissolve into water fully and fast and react with difficult degradable organic pollutants. In addition, ozone is added by the gas-liquid mixing pump at a plurality of times, which could improve the utilization ratio of ozone and could produce plenty of hydroxyl radicals. The hydroxyl radicals could swift and effective react with the organics which is difficultly degraded by the ozone, drastically break out all difficult degradable organics and make the oxidation reaction of the difficult degradable organics fast, exhaustive and energy-efficient.
Description
Affiliated technical field:
The utility model relates to a kind of sewage disposal device that utilizes ozone and ultraviolet light catalyzing technical finesse to contain hardly degraded organic substance.
Background technology:
Water environment protection is a problem of current mankind society extensive concern, and along with the fast development of Chinese national economy, the organic waste water of high density threatens to China's precious water resource.Toxic organic compound is very serious to the pollution of environment, have quantity discharged big, pollute characteristics such as wide and bio-refractory, caused people's extensive concern.Handle these toxic organic compounds although researched and developed a series of technology, say on the whole, these treatment process can't be thoroughly innoxious with these organism effectively, and are poor to biodegradability, handle difficulty.Since ozone in 1905 is applied to water treatment, obtained tangible result in actual applications.Influenced by this, the document of a large amount of relevant ozone chemistry character is delivered.Ozone reacts with unsaturated link(age) easily, as high groups of cloud density such as alkene, aromatics, sulfur-bearing are nitrogenous.But ozone oxidation reaction has certain selectivity, be suppressed for some organism such as saturated alkane, organic chloride (major part is some sterilants and priority pollutants) ozone oxidation reaction, ozone can not thoroughly be degraded to it carbonic acid gas, water and other organism at low dosage with in the short period of time.The ozone oxidation product is small molecules carboxylic acid, ketone, aldehyde material usually, and some intermediate product that resolves into may stop the further oxidation of ozone, so TOC and COD clearance are not high.Ozone is used for wastewater treatment also exists some problems, on the low side as ozone utilization rate, make ozonize expense height.As a kind of high-level oxidation technology of potentialization, photocatalysis technology has its favourable one side.But, because the recombination rate of light induced electron and photohole makes its efficient still lower.So general viewpoint thinks that photocatalysis technology will be applied in the improvement of little pollution organic waste water or drinking water source water.
Summary of the invention:
For overcome existing ozonation technology ozone utilization rate on the low side, can't oxidation or the halfway problem of oxidation to partial organic substances, also in order to overcome the lower problem of the existing oxidation efficiency of photocatalysis technology, the utility model provides a kind of ozone-ultraviolet light catalyzing water treating equipment, and this equipment can thoroughly be decomposed into carbonic acid gas and water etc. fast and efficiently with all hardly degraded organic substances.
The technical scheme that its technical problem that solves the utility model adopts is: the import of gas-liquid mixing pump connects the air outlet of water inlet pipe and ozonizer, the gas-liquid mixed pump outlet is connected to the ozone contact reaction jar, and the ultraviolet light catalyzing reactor is installed between gas-liquid mixing pump and the ozone contact reaction jar, the import of ram pump connects water inlet pipe, and the water outlet of ram pump directly links to each other with the ozone contact reaction jar.。The ozone that gas-liquid mixing pump produces ozonizer sucks the back to be mixed with water, delivers to then and carries out oxidizing reaction in the ozone contact reaction jar.Simultaneously, use ram pump to be pressurized to the pressure of 7 kilograms per centimeter about 2, and keep high pressure for some time, make ozone fully, be dissolved in the water apace, and ozone is reacted with Persistent organic pollutants fully apace to the ozone contact reaction jar.The water of handling through the ozone contact reaction jar is discharged in the ultraviolet light catalyzing reactor by the reducing valve decompression, in the ultraviolet light catalyzing reactor cavity, titanium dioxide filler is housed, titanium dioxide produces a large amount of hydroxyl radical free radicals under uviolizing, ozone also produces hydroxyl radical free radical through uviolizing, and hydroxyl radical free radical can be rapidly effectively and ozone pollutant reaction of difficult degradation all, all hardly degraded organic substances thoroughly are decomposed into carbonic acid gas and water etc.After the ultraviolet light catalyzing reaction, the ozone in the sewage is consumed, and constantly adds ozone by the gas-liquid mixing pump circulation once more, can make the hardly degraded organic substance in the sewage obtain the thoroughly decomposition of maximum ground with the ozone-depleting amount of minimum.
The beneficial effects of the utility model are: use ram pump to the pressurization of ozone contact reaction jar and keep certain pressure for some time, ozone fully dissolved, and fully, react with organic pollutant fast.In addition, gradation adds ozone, improves the utilization ratio of ozone.Simultaneously, the hydroxyl radical free radical and all organic pollutant reactions of difficult degradation of ozone that utilize the ultraviolet light catalyzing reaction to produce all thoroughly are decomposed into carbonic acid gas and water etc. with all hardly degraded organic substances.
