Description
Technical field
The utility model relates to a kind of refuse disposal system, is specifically related to a kind of garbage percolation liquid treating system.
Background technology
Along with the quickening of Re-search on Urbanization process, urban population constantly increases, scale constantly expands, and the rubbish thereupon produced becomes multiple to increase.The Yi Chao U.S. of China, occupies first place in the world with annual 1200000000 tons.The urban solid garbage of China's majority adopts the method for landfill or burning to process.In garbage loading embeading stacking process, be called percolate owing to producing a kind of waste water with high-enriched organics or inorganics under the various extraneous factor effects such as extruding.Its change of water quality scope is very big, and organic pollutant category is many, concentration is high, and has multiple carcinogens, short cancer thing, epicarcinogen, prominent carcinogens and metal ion.When percolate penetrates in underground water, surface water, namely pollute surface water quality, underground water loses use value, causes direct impact to HUMAN HEALTH and industrial or agricultural water source.Due to percolate complicated component, there is higher toxicity and there is again high cod values, high ammonia-nitrogen content simultaneously, make landfill leachate treatment difficulty very big.
All there is the problem of Concentrated liquid recharge in current domestic refuse leachate treatment technology, whole refuse landfill can regard a large bio-reactor as, although leachate recirculation can temporarily make organism in concentrated solution at landfill yard internal breakup, but the salinity in percolate particularly heavy metal ion can not decompose, along with the prolongation of landfill yard landfill time, salinity in percolate will be more and more higher, and the more and more difficult steady running of percolation liquid treating system is even paralysed.Main leachate treatment technology mainly contains UASB+A/O/A/O+MBR+RO technique, DTRO technique, MVC+DI technique at present, and its technical characterstic is as follows:
UASB+A/O/A/O+MBR+RO technique, there is complex process, technique chain is long, system management difficulty is large.This technique is recharged due to its concentrated solution 25% ~ 35%, percolate salinity in field can be caused constantly to accumulate, finally cause the imbalance of its front end biochemical system bacterium dead, the blocking of rear end membranous system salt is serious, therefore there is the problems such as continuous run stability difference in it, and at northern area, during winter operation, its biochemical part and membrane portions are subject to weather effect larger.Later stage run accessory and film replacement charge higher.These problems just percolate process these years also exist the problem place of " reach product not up to standard, up to standard do not reach product " always.
DTRO technique, carry out mandatory filtration by the diaphragm of high pressure completely, running cost is high, and water outlet yields poorly, and concentrated solution is up to 45% ~ 55%, and the problems such as winter operation difficulty is large, the later stage runs accessory and membrane module rapid wear and price is high.
Domestic also have some companies to adopt evaporation technology treating refuse percolate, what it adopted is " MVC+DI " technique, percolate is under the condition of evaporation, easy degraded part COD in percolate goes out with the band of gas with the form of VFA (VOC), its ammonia nitrogen contained also can with gas overflowing simultaneously, this technique rely on ion exchange resin by containing band distilled water in COD and ammonia nitrogen exchange adsorption, although can allow standard water discharge like this, but resins exchange is limited in one's ability, treatment capacity is extremely low, can not go back unmodified resin in time after supersaturation will be breakdown, cause system and can not steady and continuous produce.And saturated after when needing regenerating resin cost high, greatest problem is in resin reduction process, produces a large amount of waste liquid containing ammonia nitrogen and COD, causes secondary pollution again.Moreover percolate before entering evaporator evaporation process without pre-treatment, cause heat transfer tube fouling serious, have a strong impact on system water production rate, the long-term stability of influential system is run.
