Description
Technical field
The present invention relates to landfill yard sewage treatment area, specially a kind of hazardous waste security landfill sewage disposal system
System.
Background technology
Hazardous waste refers to toxicity, inflammability, corrosivity, reactivity and (or) infectivity, can to ecological environment and
Human health constitutes the waste seriously endangered, and security landfill is that hazardous waste centrally disposes one of essential important means.
Percolate, because the waste species complexity of landfill is various, the organic contamination species in percolate are easily produced during landfill
Class is more, water-quality constituents is complicated, there is certain intractability.
Compared with sanitary landfills, there is larger difference in the physicochemical property of hazardous waste and house refuse, in addition, hazardous waste
Immobilization processing is carried out before security landfill, curing agent or stabilizer can react generation stabilization, insoluble with heavy metal
In the compound of water, a certain degree of precipitation for inhibiting the pollutants such as heavy metal and organic poison.Therefore, oozed compared to rubbish
Filtrate, the concentration of the hazardous waste security landfill pollutant such as percolate organic compound and ammonia nitrogen is relatively low, mainly contains certain
The heavy metal of amount and poisonous and hazardous organic pollution need processing.
The content of the invention
(1) technical problem to be solved
In the processing procedure of hazardous waste security landfill percolate, discharge mark is extremely difficult to using single method
It is accurate.
(2) technical scheme
To achieve the above object, the present invention provides following technical scheme：A kind of hazardous waste security landfill sewage disposal
System, including be sequentially connected landfill yard continuous filter, regulating reservoir, acid adjustment pond, micro cell, Fenton oxidation pond, heavy metal reduction
Pond, coagulating basin one, sedimentation basin one, intermediate pool, hydrolysis acidification pool, contact-oxidation pool, second pond, discharge pond, the regulation
Pond is also associated with rainwater collection pool, and the discharge pond is connected in accident regulating reservoir and advanced oxidation pond, discharge pond respectively
When sewage does not reach local sewage treatment plant's adapter standard, accident regulating reservoir is discharged into, sewage is handled again according to actual conditions, is arranged
The sewage in pond that discharges water reaches local sewage treatment plant's adapter standard, is discharged into local sewage treatment plant, or be discharged into advanced oxidation
Pond carries out advanced treating, and the advanced oxidation pond is sequentially connected coagulating basin two, sedimentation basin two, reuse pool, the reuse pool
Connect landfill yard continuous filter；The sedimentation basin one and sedimentation basin two connect sludge concentration tank.
Further, pH value tester is provided with the acid adjustment pond.
Further, water quality measuring instrument is provided with the discharge pond.
(3) compared with prior art, the beneficial effects of the invention are as follows：
1st, a kind of hazardous waste security landfill field sewage disposal system is provided, using " light electrolysis+Fenton oxidation+heavy metal
The dirt of a variety of method Combined Treatment hazardous waste security landfill diafiltrations such as reduction+coagulating sedimentation+hydrolysis acidification+catalytic oxidation "
Water, reaches the standard of sewage treatment plant's adapter.
2nd, the advanced oxidation pond is sequentially connected coagulating basin two, sedimentation basin two, reuse pool, and the reuse pool connection is filled out
A continuous filter is buried, it is contaminated around hazardous waste security landfill for spraying by the wastewater ocean disposal of advanced treating
Soil, landfill yard continuous filter is discharged into by pollution-carrying water, it is to avoid soil pollution, realizes the recycling of water.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Embodiment, referring to Fig. 1, the present invention provides a kind of technical scheme：At a kind of hazardous waste security landfill sewage
Reason system, including be sequentially connected landfill yard continuous filter, regulating reservoir, acid adjustment pond, micro cell, Fenton oxidation pond, heavy metal also
Former pond, coagulating basin one, sedimentation basin one, intermediate pool, hydrolysis acidification pool, contact-oxidation pool, second pond, discharge pond, acid adjustment pond
It is interior to be provided with pH value tester.Regulating reservoir is also associated with rainwater collection pool, and discharge pond connects accident regulating reservoir and senior oxygen respectively
Change pond, discharge and water quality measuring instrument is provided with pond, when the sewage in discharge pond does not reach local sewage treatment plant's adapter standard,
Accident regulating reservoir is discharged into, handling the sewage in sewage, discharge pond again according to actual conditions reaches that local sewage treatment plant connects
Pipe standards, are discharged into local sewage treatment plant, or are discharged into advanced oxidation pond progress advanced treating, and advanced oxidation pond is sequentially connected mixed
Solidifying pond two, sedimentation basin two, reuse pool, reuse pool connection landfill yard continuous filter；Sedimentation basin one and the connection sludge of sedimentation basin two
Concentration basin.
The present invention is more using " light electrolysis+Fenton oxidation+heavy metal reduction+coagulating sedimentation+hydrolysis acidification+catalytic oxidation " etc.
The sewage of method Combined Treatment hazardous waste security landfill diafiltration is planted, originally acid adding adjusts sewage PH to 3.0-3.5, waste water
By the micro cell containing charcoal and the filler of iron, iron is anode, and charcoal is negative electrode, occurs electrochemical corrosion, this electrochemical corrosion
Most strong under acid and aerobic condition, organic matter participates in the reduction reaction of negative electrode, functional group is changed, changes original machine
The property of thing, the change of this functional group is conducive to the hardly degraded organic substance in biochemical unit to degrade.It is anti-by Fenton oxidation
Should, hydroxyl radical free radical can by oxidation operation scission of link, electro transfer and group combine etc. approach organics removal, together
When part larger molecular organicses are converted into small organic molecule.Finally, the biochemical reactions such as coagulating sedimentation are passed through so that in sewage
Insoluble COD, SS and heavy metal etc. removed by mud discharging.By light electrolysis, Fenton oxidation, heavy metal reduction
Etc. materialized pretreatment, the COD clearances of sewage reach more than 40%, and heavy metal reaches discharge standard, and biodegradability is improved,
Into subsequent biochemical processing.Biochemical treatment further improves biodegradability first by hydrolysis acidification method, finally using aerobic life
Thing method, makes sewage qualified discharge.Advanced treating chooses advanced oxidation processes and coagulant sedimentation, remaining organic in sewage to reduce
Thing, reaches reuse standard.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Improve design and be subject to equivalent substitution or change, should all cover within the scope of the present invention.
