According to the technology, a two-stage material film system is used for concentrating and separating the nanofiltration concentrated solution of the garbage leachate to extract macromolecular organic humic acids which are difficultly biochemical degraded, and the reduction of the concentrated solution is realized; meanwhile, the recycling rate of water for nanofiltration treatment is improved; according to the technology, wastewater is reused, so that the cost is saved, and the pollution to the environment is relieved.
Description
Technical field
The invention belongs to environmental technology field; specifically just relate to a kind of technique and special purpose device that the nanofiltration concentrated solution of percolate is processed; this technique extracted humic acid realize concentrated solution minimizing and process from the nanofiltration concentrated solution of percolate; realized the recycling of percolate; reduce the amount of concentrated solution, protected environment.
Background technology
Along with increasing of China's city quantity increase and population, municipal wastes is also with sharp increase, and the situation of garbage-surrounded city is very severe.At present, refuse treatment mainly be take landfill and burning as main, wherein landfill remains main mode, and accounting, between 45%-50%, is burned accounting 12% left and right, another still have 30% domestic refuse to fail to process, compare with landfill, burning method can effectively reduce rubbish capacity more than 75%, saves soil, be difficult for to produce the pollutions such as sewage permeation, and produce calorific value and can be used for heat supply, generating etc. and recycle.Therefore, the processing mode of waste incineration will be widelyd popularize.
But refuse treatment is no matter be to take landfill, or the mode of burning, the processing of percolate is all technical barrier wherein.Percolate belongs to high concentration hard-degraded organic waste water, have that complicated component, Pollutant levels are high, biological nutrition proportional imbalance, colourity be high, the feature that stink is large, biodegradability is poor, therefore, the processing of percolate is faced with the insoluble technical barrier of some always.At present, percolate mainly adopts the main process of biochemical system+MBR+ nanofiltration+reverse-osmosis treated, makes waste water can reach emission standard.The larger molecular organics matter humic acids that contains a large amount of bio-refractories in the concentrated solution of percolate after nanofiltration is processed, it accounts for the more than 70% of total organic matter, and environment and biochemical treatment system are made a big impact.At present, the processing mode of the nanofiltration concentrated solution of percolate is faced with following problem:
First, concentrated solution is directly in the existing technique of bringing back to life systematic influence system processing power, the nanofiltration concentrated solution of percolate directly returns to biochemical treatment system conventionally, humic acid is difficult to biochemical degradation in system, can build up, its concentration in system is more and more higher, finally affects the processing power of whole treatment system.
Secondly, at garbage incinerating power plant, a large amount of nanofiltration concentrated solutions conventionally returns spray and burns, but in returning spray burning process, not only heat-energy losses is large, and can cause very large corrosion to burning facility, shortens the life-span of burning facility, increase the body of heater cost of overhaul, this mode can cause huge financial loss to incineration plant.
The 3rd, flyash curing is dissolved limited in one's ability, and at garbage incinerating power plant, partial concentration liquid is generally used for flyash curing, but dissolving of flyash curing is limited in one's ability, for garbage incinerating power plant, can produce a large amount of concentrated solutions every day, and this kind of mode is difficult to its whole timely and effective dissolving, and stability is poor in the process of solidifying incineration of refuse flyash, easily produce flying dust swelling, as fast in speed of expansion, sample cracking even destroys etc.
The 4th, high and the wasting of resources of chemical oxidation treatment cost, some enterprise adopts the method for chemical oxidation to process when processing this partial concentration liquid, as Ozonation, catalytic oxidation etc., the speed of this kind of method processing humic acid is fast, efficiency is high, product (carbonic acid gas and water) does not produce pollution to environment, but this mode needs to add a large amount of oxygenants in treating processes, cost is higher, and humic acid is a kind of macromolecule organic, in agriculture production, can be used as organic fertilizer and composting raw material, directly removed, it is a kind of huge wasting of resources.Therefore, chemical oxidation is inapplicable in actual procedure.
Chinese Patent Application No. 201210289032.9 discloses a kind of percolate advanced treatment process, and the water outlet first percolate being obtained through MBR system is carried out one-level nanofiltration processing and obtained one-level nanofiltration product water and concentrated solution; Then by processing through one-level nanofiltration the product water obtaining, carry out reverse-osmosis treated, concentrated solution carries out the one-level that one-level membrane separation obtains and sees through liquid and one-level concentrated solution; Then one-level step being obtained sees through liquid and carries out secondary nanofiltration processing, and one-level concentrated solution carries out secondary membrane separation and obtains secondary through liquid and secondary concentrated solution; Finally the secondary obtaining in the 3rd step is seen through to liquid and proceed one-level membrane separation, secondary concentrated solution as fertilizer sources is used.This technology is just processed for garbage filter night, still can exist nanofiltration concentrated solution to exist and cannot obtain fully effective processing.
