Description
Technical field
This utility model is related to a kind of sewage-treatment plant, especially a kind of dress processing percolate film-filter concentration liquid
Put.
Background technology
Currently domestic widely used " biochemistry+embrane method（NF、RO）" group technology percolate is processed, this work
Skill relative maturity, stable, water quality treatment is all right, but this group technology can bring in the film process stage a certain amount of
Concentrated solution, referred to as film-filter concentration liquid.Film-filter concentration liquid all has COD concentration height, biochemical is poor, electrical conductivity is high, total metal contents in soil
High common feature, therefore processing percolate film-filter concentration liquid is a difficult point and focus.
Processing percolate film-filter concentration liquid at present mainly has recharge method, Membrane Materials, returns the techniques such as spray.
Recharge method is a kind of common method that current film-filter concentration liquid is processed, and makes junk-heap body to partly dividing greatly by recharge
Sub- Organic substance is retained and is degraded.But because organic matter degradation is slow, and high salinity and high ammonia nitrogen can press down further
The activity of methanogen processed, can accumulate quickly in dissolubility salt and the circulation of dissolved organic matter here simultaneously, make the film of formation
The electrical conductivity of filter concentration liquid increases, and osmotic pressure increases, thus affecting purification efficiency and the water outlet response rate of film processing system, reduces
The life-span of film processing system.
When Membrane Materials are using evaporation process, moisture seethes with excitement from film-filter concentration liquid and goes out, and it is dense that pollutant remain in membrane filtration
In contracting liquid.Membrane Materials one side film high cost, distillating ventilating amount is little, and energy consumption is big；On the other hand can be by temperature polarization and dense when running
The impact of degree polarization, running status is unstable.Simultaneously because the chlorine ion concentration in film-filter concentration liquid is very high, the middle temperature of evaporation process
When degree is more than 70 DEG C, chloride ion can produce strong corrosiveness to metal material, in addition contains high concentration in film-filter concentration liquid
Ca2+And Mg2+, there are scale problems in evaporation process, cause the investment of equipment and maintenance cost very big, equipment event during operation
Barrier rate is more frequent.
Return spray and be suitable for the high situation of refuse thermal value, be not suitable for the relatively low rubbish of calorific value.Return spray incinerator also can simultaneously
Lit up by the acid of film-filter concentration liquid and the corruption of salt, the maintenance requirement to equipment is high, and operation troubles rate is high.
The method of process film-filter concentration liquid emerging at present is to be processed using iron-carbon micro-electrolysis device, and Fe-C micro electrolysis react
The extremely strong oxidation-reduction quality that system has, can the effectively chemical constitution of changing section hardly degraded organic substance and characteristic, be allowed to
There is chain rupture, open loop, make hardly degraded organic substance be transformed into intermediate product or small-molecule substance, and part small-molecule substance is gone
Remove；Then, the intermediate product of generation and small-molecule substance are degraded in the presence of oxidant further, and this technique can be effective
Ground removes the pollutant in film-filter concentration liquid, reduces its COD.And due to Fe-C micro electrolysis system produce free radical have extremely strong
Oxidation-reduction quality, the chromophoric group open loop of macromole Recalcitrant chemicals can be made, resolve into low molecular intermediate product, then
Plus the synergism of oxidant, the colourity of waste water is effectively removed.
The membrane filtration that the patent document for CN202558721U for the such as Authorization Notice No. discloses a kind of percolate concentrates
Liquid processing device, its so-called retort is iron-carbon micro-electrolysis device.But during using this complete equipment, method is that membrane filtration is concentrated
Liquid is directly entered micro-electrolysis device after adjusting pH and carries out micro-electrolysis reaction, through overtesting it was found that directly carrying out light electrolysis
Method, micro-electrolysis reaction device film-filter concentration liquid out, the clearance of its COD only 25% about, to the clearance of colourity only
For 36%, treatment effect is less desirable.Inventor finds through research, due to containing more float in film-filter concentration liquid, directly
Connect it is carried out light electrolysis can lead to micro-electrolysis reaction for a period of time after float in film-filter concentration liquid cover in light electrolysis
Material surface, hinders micro-electrolysis material and waste water, and then reduces the efficiency of micro-electrolysis reaction；On the other hand, due to concentrating
Liquid contains the pollutant such as large amount of organic, metal ion, can increase uncontrollable risk during micro-electrolysis reaction.
