Description
Technical field
This utility model belongs to Pollutant Treatment technical field, particularly to a kind of thermal evaporation for processing membrance concentration liquid
Enrichment facility.
Background technology
Percolate refers to that rubbish is being stacked and during landfill due to biochemical degradations such as compacting, fermentations, exists simultaneously
The liquid of the organic or inorganic composition of a kind of high concentration produced under the seepage effect of precipitation and subsoil water, the most almost all of
Percolate both is from refuse landfill and incineration plant.
Percolate, due to complicated component, containing multiple poisonous and hazardous inorganic matter and Organic substance, also contains in percolate
There are non-chlorinated aromatic compound, chlorinated aromatic compounds of group such as being difficult to biodegradable naphthalene, phenanthrene, phosphoric acid vinegar, phenolic compound
With amino benzenes compounds etc..In percolate, CODcr, BOD5 concentration peak is up to thousands of to several ten thousand, and municipal sewage phase
Ratio, concentration is high, so percolate is to be directly discharged into municipal sewage treatment pipe without strict process, disposal
Road.It is said that in general, CODcr, BOD5, BOD5/CODcr increase with " age " of landfill yard and reduce, level of alkalinity then raises.
So percolate could be discharged after treatment.
The mode that landfill yard and incineration leachate use integrated treatment at present is the most, the most all uses early stage to locate in advance
Aerobic Process for Treatment, ultrafiltration the most again, nanofiltration and reverse osmosis after first anaerobism after reason.Macromole and float can be leached, thoroughly by ultrafiltration

Enter nanofiltration to process further；Almost all of humic acid and bivalence and above ion isolation are gone out by NF membrane, isolated dense
Contracting liquid accounts for entering the 20% of nanofiltration.Nanofiltration concentrated solution is higher due to salinity and organic concentration, it is not easy to deposits or fills,
Need to process further.Through the solution of NF membrane due to containing higher Na+、Cl-Deng monovalent ion, not up to discharge standard,
Need nonetheless remain for processing further, therefore also need to reverse osmosis process.Clear liquid after reverse-osmosis treated is permissible after reaching discharge standard
Discharging or for government utility pouring etc., reverse osmosis concentrated liquid accounts for entering about the 25% of the total amount of counter-infiltration system, main
Wanting composition is Na+、Cl-Solution Deng monovalent ion.
For reverse osmosis concentrated liquid, owing to contaminative is relatively low, in the way of can filling again after taking natural air drying, but lean on
Natural air drying is inefficient, floor space is bigger；Nacl can also be become by processes, but relatively costly；All right
By the way of heat treatment concentrates, promote evaporation, but select the improper heat exchange contact surface that easily causes of Technology for Heating Processing to crystallize, lead
Cause heating surface heat conduction inequality, heat transfer effect declines.
Process to nanofiltration concentrated solution, some technique is taked backflow to reenter percolation liquid treating system, is taked this kind of side
Although formula can reduce the total amount of humic acid, but be as cycle-index and increase, Ca2+、Mg2+、CO2-、SO4 2-Plasma concentration liter
Height, impacts the percolation liquid treating system before nanofiltration, so backflow can not finally solve nanofiltration concentrated solution；Spray into rubbish
Burn burner hearth and heating surface can be caused corrosion and scale damage；Recharge landfill yard to be the most also intended to be again introduced into percolate.Cause
These various processing methods researching and solving nanofiltration concentrated solution and technique are arisen at the historic moment.
Nanofiltration concentrated solution and reverse osmosis concentrated liquid are referred to as membrance concentration liquid.
The outer typical method disposing membrance concentration liquid of Present Domestic recharges, Membrane Materials, evaporation, advanced oxidation etc..But
Actual motion application have also discovered some problems.
Recharge method.Recharge and can improve the response rate, increase membrane surface flushing flow velocity；But the fraud As time goes on, recharged
End gradually displays, and domestic refuse landfill occurs in that the accumulation of pollutant the most in various degree, and percolate electrical conductivity raises, film
Producing water ratio declines, and electrical conductivity even occur increases the problem causing membrane filtration to lose efficacy.
Membrane Materials method i.e. submerged combustion evaporation technology, is a kind of nothing evaporation mode of fixing heat-transfer area, by fuel and air
Send into against liquid level or be immersed in the combustor under liquid level and burn completely, then high-temperature flue gas is injected directly into liquid it
In to add hot liquid.High-temperature flue gas enters and rises with a large amount of minute bubbles forms after liquid, due to flue gas and liquid mixing with stir
Dynamic very strong, thus significantly enhance diabatic process, tail gas is down to temperature much the same with liquid phase before discharge, heat transfer
Efficiency may be up to more than 95%.
Evaporation is at certain temperature and pressure, and the most volatile Component seperation in mixed solution is gone out
Method.Evaporation treatment process can be by the volume concentration of pending solution to the 2%～10% of not enough stock solution volume.
Advanced oxidation processes.For Mu Qian, the most several technology, high-level oxidation technology is to process percolate, film
The reasonable selection of concentrated solution, has the most a little: 1. efficient, and the speed of high-level oxidation technology degradation of organic substances is very fast, and this is
Other several technology cannot be compared.2. product harmless, the intermediate product in advanced oxidation processes oxidizing process all can continue same
Hydroxyl radical reaction, until being finally oxidized to carbon dioxide and water completely, thus has reached the thorough mesh removing TOC, COD
's.3. it is a kind of physical and chemical process due to it, it is easy to be controlled by, with satisfied process needs.
Above-mentioned several method has employing in membrance concentration liquid processes, but all dense without reference to utilizing waste heat evaporation process film
The device of contracting liquid, it is impossible to effectively utilize fume afterheat.
