Abstract
The invention discloses a Fenton oxidation wastewater processing system. A fluidized bed Fenton oxidation processing device is arranged behind an anaerobic and aerobic biological processing device, and an electroreduction Fenton oxidation processing device is arranged in front of the anaerobic and aerobic biological processing device. By combining use of fluidized bed Fenton oxidation processing and use of electroreduction Fenton oxidation processing, both of electric field and an iron oxide crystallization catalyst can promote the decomposition of organic matters, so the organic matter processing efficiency is improved, industrial wastewater with the COD concentration of 50-50000mg/L can be processed, and the sludge output is reduced.
Description
Technical field
The present invention relates to technical field of waste water processing, relate in particular to a kind of Fenton oxidized waste water treatment system.
Background technology
The Fenton reaction was found ferrous ion Fe in 1894 by Fenton
2+Be hydrogen peroxide H
2O
2Catalyzer, produce a kind of high oxidative capacity radical of (being only second to fluorine) (hydroxyl free radical OH).The Fenton reaction has very strong oxidation capacity, and the numerous species organism is all had oxygenizement, is used to organic wastewater with difficult degradation thereby and handles.With Fenton reaction reagent (ferrous salt and strong oxidizer such as hydrogen peroxide H
2O
2) add in the pending waste water, ferrous ion produces the hydroxyl free radical of strong oxidation with the oxygenant effect in water, the final oxidation of the organism of difficult degradation in the waste water, carbonization are become degradable small molecules, with reduction COD, reaches degradation effect like carbonic acid gas and water.
Fluid bed Fenton method oxide treatment is that iron mud is become the ferriferous oxide crystallization, has catalytic effect, and can reduce by 70% sludge quantity, and reaction formula is H
2O
2+ Fe
2+→ OH+H
2O+ FeOOH.But fluid bed Fenton method is suitable for handling the waste water of COD concentration range at 50-500mg/L, is difficult to realize treatment effect preferably for the waste water of high COD concentration.
Summary of the invention
The present invention provides a kind of Fenton oxidized waste water treatment system for the problem that solves above-mentioned prior art existence, can handle the trade effluent of COD concentration range at 50-50000mg/L.
The object of the invention is realized through following technical scheme:
A kind of Fenton oxidized waste water treatment system is being sick of, fluid bed Fenton oxidizing treater is being set after the happy expression biological treatment device, be sick of, the happy expression biological treatment device also is provided with electrolytic reduction Fenton oxidizing treater before.
Said electrolytic reduction Fenton oxidizing treater and be sick of, be provided with between the happy expression biological treatment device mix well, oil removing, coagulation pretreating device.
Saidly mix well, the chemical sludge treatment system be set in the oil removing, coagulation pretreating device.
Saidly be sick of, the biological sludge treatment system be set in the happy expression biological treatment device.
In the said fluid bed Fenton oxidizing treater mud electrolytic recovery treatment system is set.
Compared with prior art, the present invention has following beneficial effect:
Electrolytic reduction Fenton method oxide treatment is to add hydrogen peroxide H
2O
2Be oxygenant, ferrous ion Fe
2+Be catalyzer, reaction generates hydroxyl free radical (OH) and ferric ion Fe
3+, and ferric ion is reduced to ferrous ion at negative electrode, and therefore constantly the recycle ferrous ion is participated in reaction, and reduces the mud that 80% ferric iron is produced, and reaction formula is Fe
3+→ Fe
2++ e; H
2O
2+ Fe
2+→ OH+OH
-+ Fe
3+Carrying out oxide treatment with electrolytic reduction Fenton method has the following advantages:
1, the electric field organism that dissociates, promotes oxidn agent promote the treatment effect (approximately promote 30-90%) of Fenton method to COD to organic resolving power;
2, electrolytic reduction Fenton method is when treatment of high concentration COD, because of continuous recycle Fe
2+Participate in reaction, can reduce the iron usage quantity in a large number, promote the oxygenant utilising efficiency;
3, electrolytic reduction Fenton method is saved half electric power than electrolytic oxidation enton method;
4, the reaction back is Fe
3+Solution, the coagulating agent that can be used as the coagulating sedimentation unit uses;
5, floor space is little, and quite, floor space only needs its 10-20% to function with " biological treatment cooperates traditional F enton method ".
Fluid bed Fenton method oxide treatment and the combination of electrolytic reduction Fenton method oxide treatment are used; Electric field and ferriferous oxide crystalline catalysts all can promote organism to decompose; Raising is to the organism processing efficiency; Can handle the trade effluent of COD concentration range, and reduce sludge yield at 50-50000mg/L.
Description of drawings
Fig. 1 is the schematic flow sheet of one embodiment of the invention.
Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1; A kind of Fenton oxidized waste water treatment system; Comprise electrolytic reduction Fenton oxidizing treater 1 successively, mix well, oil removing, coagulation pretreating device 2, be sick of, happy expression biological treatment device 3 and fluid bed Fenton oxidizing treater 4; Wherein, mix well, chemical sludge treatment system 5 be set in the oil removing, coagulation pretreating device 2; Be sick of, biological sludge treatment system 6 be set in the happy expression biological treatment device 3; Mud electrolytic recovery treatment system 7 is set in the fluid bed Fenton oxidizing treater 4.
Trade effluent at first is transported to electrolytic reduction Fenton oxidizing treater treatment of high concentration COD, hydrogen peroxide H through transferpump
2O
2With ferrous ion Fe
2+Reaction generates hydroxyl free radical (OH) and ferric ion Fe
3+, and ferric ion is reduced to ferrous ion at negative electrode, therefore constantly the recycle ferrous ion is participated in reaction, reduces the iron usage quantity in a large number, and reduces the mud that 80% ferric iron is produced; Then waste water get into mix well, oil removing, coagulation pretreating device handle Fe
3+Solution can be used as coagulating agent and uses; The mud that produces gets into the chemical sludge treatment system and carries out concentration, and the waste water entering is sick of, the happy expression biological treatment device is handled, and the mud of generation gets into the biological sludge treatment system and handles; And continuing to flow into fluid bed Fenton oxidizing treater, handles waste water; The mud that produces in this step gets into mud electrolytic recovery treatment system and handles, and is last, and trade effluent can reach the wastewater discharge standard that country formulates after treatment.Fluid bed Fenton method oxide treatment and the combination of electrolytic reduction Fenton method oxide treatment are used, can be improved, can handle the trade effluent of COD concentration range, and reduce sludge yield greatly at 50-50000mg/L to the organism processing efficiency.
More than the disclosed several specific embodiments that are merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
