Description
Technical field
The utility model relates to technical field of waste water processing, is specifically related to the device of a kind of microwave and electricity flocculation combination treatment dyeing waste water.
Background technology
In textile industry, dyeing and the processed finished products operation that is absolutely necessary are so production process can produce a large amount of waste water.Because dyestuff is just towards anti-photodissociation, anti-oxidant, antibiooxidation future development, thereby the dye wastewater treatment difficulty is strengthened.Waste water from dyestuff generally adopted the array mode of biology, physics, chemical process to process in the past, but because the industrial water drainage complicated component, intractability is still larger.Dyeing waste water mainly is comprised of desized wastewater, boiled-off waste water, bleaching effluent, mercerizing waste water, dyeing waste-water and printing waste water, has that Pollutant levels are high, kind is many, contain poisonous objectionable constituent and colourity high.In recent years because the progress of finishing process in printing and dye-ing technology makes the bio-refractory organism such as PVA slurry, artificial silk alkaline hydrolysis thing (mainly being O-phthalic acids material), New-type adjuvant enter in a large number dyeing waste water.
Domestic main treatment technology about dyeing waste water has oxidation style, absorption method, reverse osmosis method, electrolytic process, flocculent precipitation, biochemical process etc. at present, although these methods have obtained certain effect, but still existing problems.That internal electrolysis has is cheap, equipment simple, reduced investment, again can the treatment of wastes with processes of wastes against one another etc. advantage, but traditional Internal Electrolysis Process for Treating dyeing waste water weak effect.Be considered to preferably a kind for the treatment of process of effect with ozone decolorization, but cost is higher.In addition, macromolecule organic and part dyestuff are difficult to process by biological degradation.
Microwave refers to as 300M-300GHz, is the abbreviation of a limited frequency band in the radiowave.The microwave electromagnetic field energy makes polar molecule produce the high speed rotating collision and produces heat effect, reduce the activation energy of reaction and the chemical bond strength of molecule, the i.e. concussion of polar molecule in microwave field can make chemical bond rupture, utilizes these characteristics so that the technology of microwave has obtained application in waste water treatment process.Microwave direct radiation method is processed waste water and is referred to waste water is placed directly in the microwave field and shine.When microwave oven magnetic gives off the microwave of very high frequency, microwave energy field is with the speed of per second 24.5 hundred million times conversion positive-negative polarity constantly, great change has occured in molecular motion, the molecule high-speed motion, run foul of each other, rub, push, micro-wave energy is converted into heat energy, thereby temperature is risen, and reaches processing intent.
In recent years, the research and development of senior oxidation technology such as electricity flocculation etc. is for the organic waste water of difficult degradation provides new thinking.Electric flocculation technique is under the electric field action, utilize soluble anode or sacrificial anode and produce a large amount of positively charged ions waste water is flocculated, thereby the water purification technology with pollutant removal, it has electrochemical oxidation, flocculation and air supporting three's characteristics simultaneously concurrently, not only can with the other technologies flexible combination, the pharmaceutical chemicalss such as not needing to add oxygenant, flocculation agent of disposing of sewage, and it is high to have a processing efficiency, floor space is little, easy to operate, the advantage such as applied widely is the technology that present wastewater treatment has competitive power.
The utility model content
