Description
Technical field
The invention belongs to landfill leachate treatment research field, be to process percolate in existing bioelectrochemical system
On Research foundation, determine that a kind of double-current method microorganism desalination pond is innoxious, the method for recycling treatment percolate.
Background technology
Percolate be rubbish produce during harmless treatment endanger by-product in a large number, be broadly divided into rubbish
Landfill percolate and garbage burning factory percolate.The percolate that domestic refuse landfill produces accounts for the 52% of garbage loading embeading amount
～82%, the percolate that garbage burning factory produces accounts for the 5～28% of waste incineration amount, and the annual percolate produced can be high
Reach 1 billion cubic meter.
The pollutants from landfill leachate discharge capacity that China produces every year is respectively as follows: COD 320,000 tons, ammonia nitrogen 3.2
Ten thousand tons, accounting for the 1.1% and 1.8% of whole nation total emission volumn, heavy metal concentration, up to 3～300 times of discharge standard, is let slip at heap
Also can form such as methane, hydrogen sulfide, ammonia, mercaptan etc. in journey makes people produce the foul gas of the symptoms such as nauseating, hematuria, dizziness.Separately
Outward, percolate enters water body can also accelerate the eutrophication process of water body, makes algae breed rapidly, and heavy damage water body is raw
State system, reduces oxygen in water, causes the death of animal in water, ecological environment and health are caused serious threat.Cause
This, processing percolate safely and efficiently becomes the environmental problem being badly in need of solving.
Bioelectrochemical system is a kind of innoxious, resource biological wastewater treatment technology, and it utilizes biocatalyzer (main
If producing the effect of electricity antibacterial) on anodic-cathodic, there is redox reaction, can be used for when being connected by external circuit producing electricity
Can, or high value added product can be produced at anode and cathode two ends applying supplementary energy.In percolate, the BOD of high-load is micro-for producing electricity
The substrate that biological offer is good, the positive and negative ion of high concentration can be effectively improved the electrical conductivity in bioelectrochemical system, in reducing
Resistance so that bioelectrochemical system processes percolate the biggest feasibility.Bioelectrochemical system system is at garbage filter
Liquid process aspect also has three below advantage: 1, both had the function of biological treatment, it may have the reinforcement of electrochemistry processes
Potentiality, can realize the potent process of hardly degraded organic substance.2, under the effect of internal electric field, zwitterion has displacement
Characteristic so that it is there are the potentiality of resource reclaim.3, pH can be made to raise by the reduction of hydrogen or oxygen near cathode chamber/negative electrode, have
It is beneficial to the removing of pollutant, such as the deposition removal of heavy metal ion.
Summary of the invention
It is an object of the invention to the double-current method microorganism desalination pond electro-chemical systems by building four Room, it is provided that a kind of rubbish
Percolate double-current method microorganism desalination pond processing method.
Technical problem is that of present invention mainly solves realizes the synchronization process of percolate, desalination and resource, reaches
While the stabilized treatment percolate of double-current method microorganism desalination pond, efficiently utilize the energy extracted from percolate.
In order to realize the purpose of the present invention, the technical solution used in the present invention is:
A kind of percolate double-current method microorganism desalination pond processing method, comprises the following steps:
