Description
Technical field
The present invention relates to a kind of bionical oxygenation light electrolysis artificial swamps, belong to water-treatment technology field.
Background technology
Artificial Wetland Techniques, in sewage treatment field using more and more common, but people are also becoming increasingly recognized that wherein
There is limitation：(1) with the increase of running time, clogging can be more apparent, the dirt-removing power of wetland gradually by
Limitation, is finally forced to stop using；(2) artificial swamp compared to other processing means for, it is difficult to formed and suitable go to decontaminate
Substance environment is contaminated, causes reaction rate slower, thus the removal efficiency of COD, N, P is not high；(3) shortage of the oxygen also largely upper limit
It has made wetland and has played its maximum efficiency；(4) deficiency of the carbon source in wetland for denitrogenation dephosphorizing causes its effect to be restricted；
(5) dephosphorization relies on microorganism to inhale phosphorus substantially, and no other strengthen means.
The problem of for wetland, takes a series of measures in engineering as strengthened reoxygenation means to improve wetland
Operation conditions, but various reason still limits wetland and maximumlly plays its effect.Such as：Dropping reoxygenation can
Water inlet dissolved oxygen is improved, but is influenced by saturated dissolved oxygen, reoxygenation ability is limited, and being exposed to outer water dropping device can band
Carry out freezed in winter, the problems such as summer grows mosquitos and flies.Artificial aeration needs to increase level-one wetland offer denitrification environment and place, increases
Add capital cost, while increasing energy consumption, operating cost is caused to increase, therefore in order to make wetland high-efficiency run, it is also necessary to do into one
Step improves.
Invention content
Goal of the invention：Technical problem to be solved by the invention is to provide a kind of bionical oxygenation light electrolysis artificial swamps, should
Artificial swamp can form the anoxic of cycle alternation, anaerobic and aerobic reaction environment, to enhance nitrification and denitrification effect
It carries out, and then effectively improves the nitric efficiency of entire artificial swamp；Meanwhile alternately anaerobic and aerobic environment also contributes to dephosphorization effect
The raising of rate；Secondly, the biodegradability of sewage can be improved, required carbon source is provided for subsequent biochemical reaction, is further increased
Contaminant removal efficiency, and then extend the cycle of operation of artificial swamp；Third need not additionally install exposure additional in aerobic reaction environment
Device of air makes aerobic environment remain high dissolved oxygen content by the synergistic function of filler and siphon；4th, this hair
Packing layer in bright wetland has efficient contaminant removal efficiency, and the environment pH formed is low, so as to accelerate the anti-of wetland
Answer rate.
In order to solve the above technical problems, the technology used in the present invention means are：
A kind of bionical oxygenation light electrolysis artificial swamp, by multigroup anoxic-anaerobic-aerobic artificial swamp, drop-over forms successively,
Multigroup anoxic-stepped the arrangement of anaerobic-aerobic artificial swamp；Every group of anoxic-anaerobic-aerobic artificial swamp is by anoxic Manual moist
Ground, anaerobic manpower wetland oxidation and artificial wetland of becoming reconciled are sequentially connected composition, the anoxic in every group of anoxic-anaerobic-aerobic artificial swamp
Artificial swamp, anaerobic manpower wetland are become reconciled oxidation and artificial wetland also stepped arrangement；Every group of anoxic-anaerobic-aerobic artificial swamp
In anoxic artificial swamp and anaerobic manpower wetland in be filled with certain depth packing layer, every group of anoxic-anaerobic-aerobic people
Siphon pipe is equipped in aerobic artificial swamp in work wetland, the water intake system that siphon pipe crosses aerobic artificial wetland treatment drains
In the anoxic artificial swamp of mouth or next group of anoxic-anaerobic-aerobic artificial swamp；Wherein, packing layer in anoxic artificial swamp
Loading account for the 10%~12% of wetland volume, in anaerobic manpower wetland the loading of packing layer account for wetland volume 16%~
18%.
Wherein, the anoxic artificial swamp and anaerobic manpower wetland are all made of effluent weir water outlet.
Wherein, described filler layer is mixed by the component of following parts by weight：10~12 parts of iron carbon fillers and 3~4 parts
Manganese dioxide particle.
Wherein, described filler layer is mixed by the component of following parts by weight：20~30 parts of iron carbon fillers, 5~7 part two
Manganese oxide, 2~3 parts of di-iron trioxides, 1~2 part attapulgite modified, 2~3 parts of kaolin, 1~2 part of swelled ground, 1~2 part of plant
Fibres and 1~2 part of activated sludge powder.It is filled in anoxic artificial swamp and anaerobic manpower wetland in wetland of the present invention
Packing layer by reaction the wetland can be made be in anoxic and anaerobic environment, while packing layer can also by reaction make correspond to it is wet
The pH on ground is lower, to accelerate the reaction rate of wetland.
Wherein, every group of anoxic-anaerobic-aerobic artificial swamp bottom surface is equipped with antiseep water barrier.
Compared with the prior art, technical solution of the present invention have the advantage that for：
First, multi-stage anaerobic-stepped arrangement of anaerobic-aerobic artificial swamp is passed through waterpower by artificial swamp of the present invention
Means reach the control run to wetland, and whole process is made to can make full use of water pump head, convert potential energy to by siphon
Kinetic energy, second, packing layer is placed in anoxic and anaerobic manpower wetland, can not only be reacted macromolecular by the Inner electrolysis of filler
Organic matter (i.e. Recalcitrant chemicals) is degraded to small organic molecule, while can also cooperate with one landing of microorganism in artificial swamp
Small molecule contaminants (helping the microorganism degradable pollutant of fast degradation together) are solved, are blocked to effectively reduce in wetland
The generation of phenomenon extends the cycle of operation of wetland；Third, the Inner electrolysis reaction of filler can consume the oxygen of anoxic and anaerobism section
Gas forms anoxic and anaerobic environment conducive to denitrification, improves the efficiency of system denitrogenation dephosphorizing；4th, it doses in layer
Manganese dioxide particle can make filler have more efficient contaminant removal efficiency, and can also make environment pH reductions, to
Accelerate reaction rate；More importantly manganese dioxide particle can also react with the organic ligand in system, mitigate organic match
Body produces H to microorganism2O2The inhibition of effect, and then further increase the utilization ratio and contaminant removal efficiency of filler in system；
5th, the reoxygenation effect that aerobic section siphonic effect is brought makes that aerator need not additionally be arranged in aerobic artificial swamp again, no
Only realize the purpose of low energy consumption, and the largely pollutants such as remaining organic matter and nitrogen phosphorus in consumption system.
