System is answered, organic wastewater with difficult degradation thereby can be processed, improve treatment effeciency.
Background technology
In recent years, gradually stepping up with environmental requirement, the up to standard of organic wastewater with difficult degradation thereby is treated as vast environmental protection enterprise
Industry and researchers urgently need the difficult problem for solving.Advanced oxidation processes can will pollute the direct mineralising of goods and materials or be carried by oxidation
The biodegradability of high sewage, with use range it is wide, oxidability is strong, reaction rate is fast the features such as, become currently processed difficult drop
The important means of solution organic wastewater.
It is that main active material carrys out pollution degradation material that advanced oxidation processes are mainly with hydroxyl radical free radical (HO).Hydroxyl
Free-radical oxidation reduction potential higher (2.80V), is strong oxidizer, but, and to dirt due to hydroxyl radical free radical oxidizing condition strictly
Dye material degraded non-selectivity, using when by the background substance (carbonate, bicarbonate, natural organic matter etc.) in water body
Affect big, cause oxidation effectiveness often preferable not to the utmost.
Persulfate oxidation technology is developed in recent years with potentiometric titrations (SO4 ‾) it is main active substances
The advanced oxidation technology of degradation of contaminant.Persulfate belongs to hydrogen peroxide (H2O2) derivative, can produce sulfate radical from
By base, potentiometric titrations have stronger redox ability, and can degrade in theory most of organic matters.But unactivated
（Catalysis）In the case of, its oxidative degradation organic matter it is limited in one's ability.
Persulfate activation mainly has three kinds of activation methods such as heat, transition metal ions, light.Wherein, thermal activation high energy consumption, mistake
Crossing metal ion activation can bring new pollution, and photoactivation efficiency is high, low cost, and ultraviolet light itself has certain oxidation
Ability, oxidation-degradable some organic pollutants.
Utility model content
In order to solve the above problems, the utility model gets up excessively stream hydrochlorate and UV light combined, there is provided a kind of photocatalysis
Oxidized waste water reaction system, first pumps into organic wastewater and oxidant in reaction system, in the presence of stirring, quickly simultaneously
Uniform mixing, then enters reaction zone from bottom, and under the collective effect of ultraviolet light and oxidant, the difficult degradation in waste water divides greatly
Sub- organic matter is oxidized and resolves into small-molecule substance, and water outlet COD reaches design requirement.
Technical scheme
In order to realize above-mentioned technical purpose, the utility model designs a kind of photochemical catalytic oxidation waste water reaction system, its feature
It is：It includes raw water box, intake pump, dosing tank, dosing pump, reactor, product water tank, power supply.
Raw water box is connected with reactor, and intake pump is housed on connecting line, meanwhile, dosing tank is connected with reactor, connection
Dosing pump is housed, reactor water outlet output end is connected with water tank is produced on pipeline.
Further, the reactor is mainly made up of mixed zone with reaction zone.
Further, mixer and partition wall baffle plate are provided with the mixed zone, and the bottom of partition wall baffle plate is provided with aperture.
Further, at least a set of ultraviolet source being vertically arranged is provided with the reaction zone；Often cover light source include uviol lamp,
Quartz ampoule and power supply；Uviol lamp is placed in inside quartz ampoule, the quartzy seal of tube.
Beneficial effect
The utility model provides a kind of photochemical catalytic oxidation waste water reaction system, using the strong oxidizing property of persulfate oxidation agent
With the collective effect of ultraviolet light, the organic matter (COD) in organic wastewater, colourity are carried out into oxidation Decomposition into small molecule, to ring-type
And long-chain macromolecule organic matter carries out open loop chain rupture, complicated functional group is cracked, water outlet COD can be made to reach design requirement.
Description of the drawings
Accompanying drawing 1 is technique of the present utility model and special purpose device annexation schematic diagram.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is elaborated.
Embodiment
