Description
Technical field
The invention belongs to landfill leachate treatment fields, are related to a kind of technique suitable for UASB processing landfill leachate.
Background technique
Major way of the municipal solid waste sanitary landfill as house refuse final disposal, percolate treatment facility are
One of main indicator of domestic garbage was harmlessly treated, percolate whether up to standard is the emphasis examined.Consumer waste infiltration liquid is total
Body has high organic high-concentration ammonia-nitrogen, high chroma, high conductivity, salt content height, carbon-nitrogen ratio imbalance, difficult for biological degradation, pollution danger
The features such as evil is big, processing difficulty are high.
Due to the growth with the garbage loading embeading time, percolate will appear aging phenomenon, COD, BOD concentration in percolate
Decline, ammonia-nitrogen content raising, carbon, nitrogen are reduced than imbalance, biodegradability, are caused traditional biochemical treatment system that can not operate, are made
It is greatly reduced with the methane phase efficiency of UASB anaerobic reactor processing percolate, a series of problems, such as ammonia nitrogen removal effect is poor produces
It is raw, while grid+conditioning tank+hydrolysis acidification pool+pond dosing chamber+UASB anaerobic reactor+MBR+A/O is used in existing technology
+ disc tube reverse osmosis (dt-ro) film (DTRO)+disinfection process flow carries out the processing of percolate, needs to carry out water temperature tune in dosing chamber
Section increases operating cost;And since UASB reactor effluent quality index is still higher, it cannot directly enter MBR system, film
Bioreactor (MBR system) water inlet preferably meets COD and is less than the limit values such as 50mg/l less than 500mg/l, ammonia nitrogen, directly passes through MBR
The service life for reducing MBR system is be easy to cause after system processing, which is difficult to later refuse landfill diafiltration in 5 years
NH_3-N treating in liquid is up to standard;Biochemistry pool water outlet simultaneously is directly entered disc tube reverse osmosis (dt-ro) membranous system, makes disc tube reverse osmosis (dt-ro) film
System operating load is higher, Yi Fasheng fouling membrane, increases operating cost.
Summary of the invention
The purpose of the present invention is to provide a kind of techniques suitable for UASB processing landfill leachate, in UASB anaerobic reaction
Heating system is set when in device, can be realized and heated automatically during anaerobic reaction, heated without dosing chamber, is saved
Save cost, while in UASB anaerobic reactor treated sewage by Two-Stage Biochemical reaction tank removal organic matter and denitrogenation,
Cancel MBR technique in anaerobic reactor subsequent treatment process, also leachate quality can be made to reach subsequent using Two-Stage Biochemical system
Processing requirement, and the film cost and operating cost of MBR membrane processing method are all higher, investment and operation can be reduced by cancelling MBR technique
Cost.Water outlet flows into qualified discharge after ultrafiltration system, nanofiltration system and reverse osmosis membrane treatment system classification are handled after biochemical treatment,
Because the molecular size range of ultrafiltration, nanofiltration and reverse osmosis treatment successively decreases step by step, subsequent processing load can reduce using classification processing,
Extend the operation time limit of each membranous system, reduces operating cost.
The purpose of the present invention can be achieved through the following technical solutions:

Second step, conditioning tank water outlet flow into hydrolysis acidification pool, and the hydrolysis acidification bacterium in hydrolysis acidification pool can be by long-chain high score
Sub- polymer hydrolysis acidification be the stronger small organic molecule alcohol of biodegradability or acid, can also be by partially not biochemical or biochemical
Weaker heterocycle type organic breaks ring and is degraded into biochemical organic molecule, improves dirty organic pollutants BOD5/CODCrValue,
Improve the biochemical of entire sewage;
Treated in second step percolate is entered sieve pond from hydrolysis acidification pool water outlet, examined in sieve pond by third step
PH value after surveying hydrolysis acidification, since refuse landfill diafiltration PH index in China's is generally in 6.51-8.25, after hydrolysis acidification
PH value can be down to 5.2, adjust pH value to 6.8-7.2 using sodium carbonate, and be allowed to meet methane phase in anaerobic reactor is suitable for
Condition;
Sieve pond water outlet pump in third step is promoted to UASB anaerobic reactor, the UASB anaerobic reactor by the 4th step
Bottom is equipped with heating system, and water distributor is placed in heating system, and the sewage after heating flows into pond body, passes through anaerobism ammonia oxygen in pond
Changing large amount of organic and generation in reaction directly removal sewage has the biogas for recycling and being worth, can after the collecting methane of generation
For the heating system of UASB anaerobic reactor bottom, operating cost is saved;
5th step, percolate enter two-stage A/O biochemical reaction tank after UASB anaerobic reactor Anaerobic Treatment, and percolate exists
Organic matter and denitrogenation are sufficiently removed in biochemistry pool, anaerobic reactor water outlet flows into level-one anoxic pond, after Aerobic biological process
Sewage, the ammonia nitrogen of wherein most is oxidized into nitrite (NO by nitration reaction2 -- N), nitrate (NO3 -- N),
Aerobic tank effluent recycling a part is to anoxic pond, in anaerobic condition, denitrifying bacterium using the nitrogen in nitrate as electron acceptor,
Nitrogen in nitrate is reduced into nitrogen (N by oxidation of organic compounds2), organic matter becomes carbon dioxide (CO2), to complete sewage
Remove organic matter and denitrification process;The sludge of the generation in biochemical reaction tank is discharged into sludge concentration tank simultaneously, de- by sludge
Water dispenser, which is handled, is down to 60% solid matter below to moisture content and is sent into refuse landfill landfill, supernatant be pumped into conditioning tank into
Row circular treatment;After garbage loading embeading field time was up to 5 years or more, ammonia-nitrogen content is increased, and content of organics reduces, and level-one is good
Oxygen pond effluent recycling a part makes to sieve pond into NO in the sewage of UASB anaerobic reactor2 --N/NH4 +- N close to 1.32,
The effective and thorough ammonia nitrogen for removing high ammonia-nitrogen wastewater can be had by sufficiently carrying out Anammox reaction;
6th step is lifted into ultrafiltration system by elevator pump by the percolate that the 5th step mesophytization is handled, in ultrafiltration
A kind of pressure activated film is utilized in system, colloid, particle and molecular weight phase in trap water under extraneous motive force (pressure) effect
To higher substance, and water and relatively small particles of solute penetrate UF membrane;It can be retained point by the screening of the micropore of film surface
The substance that son amount is 3x10000-1x10000, and it is greater than particle, the macromolecular of fenestra etc. since sieving actoion is trapped, thus
Most of colloidal silicon is removed, while can remove a large amount of organic matter etc.;
7th step, ultrafiltration system water outlet enter nanofiltration system, wherein nanofiltration (NF) between ultrafiltration and it is reverse osmosis between, section
Stay molecular weight in the range of 80-1000, aperture is several nanometers;
8th step, enters reverse osmosis membrane (RO) system after nanofiltration system, and the processing by RO system reaches discharge mark
Reuse or discharge after standard driven by pressure, will be in solution by means of the selective retention effect of semi-permeable membrane in counter-infiltration system
Solute is separated with solvent, and reverse osmosis film used is semi-permeable membrane, its micropore is smaller, diameter about 2nm, (or can only be had by water
Solvent), the substance of salt and other dissolutions cannot be passed through.It therefore can be by the inorganic ions, thin in raw water with reverse osmosis technology
