Description
Technical field
The present invention relates to garbage loading embeading percolation liquid processing technology fields, especially composite type artificial wetland garbage loading embeading percolation
Liquid filtration system.
Background technology
With the quickening of Chinese Urbanization's and the raising of Living consumption, the yield of domestic waste is growing day by day.
2013, Chinese house refuse total output had reached 1.73 hundred million kilograms, since processing cost is low, was filled out using rubbish health
The rubbish for burying processing accounts for 80% or more of total Municipal Garbage Yield；Since the ingredient of rubbish is sufficiently complex, generated landfill leachate
It is the special waste of a kind of complicated component, high organic matter high ammonia nitrogen and high salinity, and 1 ton of percolate is approximately equivalent to 100 tons of city dirts
The concentration of pollutant contained by water；If percolate direct emission, the environment of surrounding, especially underground water can be generated irreversible
Harm.It handles, but transportational process may be revealed, can aggravate pair it is generally necessary to transport percolate to sewage treatment plant
The pollution of surrounding area and underground water source, and processing method that sewage treatment plant uses (such as anti-diafiltration techniques, ultrafiltration and smelly
Oxygen) higher technology and cost of labor are generally required, it is not particularly suited for applying in many developing countries.
The advantage in terms of economy and environment is had both, is clearly more to attract closer to natural artificial wet land treating system
The processing garbage loading embeading percolation liquid measure of power.But the pollutant concentration of garbage loading embeading percolation liquid is high, passes through artificial swamp mistake for a long time
Filter is easy to cause artificial swamp and blocks, and percolate treating capacity is caused to reduce, and pollutant dispels efficiency reduction；And garbage loading embeading
Percolate generally carries foul odour, and pollutant load is very high, and often contains bio-toxicity, when needs are near artificial swamp
When carrying out artificial water quality measurement or executing operation, once safeguard procedures are not in place, the health of operating personnel will be endangered；And it is existing
Somebody's work wet land treating system takes up a large area, and land utilization ratio is low；And incomplete percolate is once filtered by Manual moist
Ground bottom enters underground water, can also inevitably result in secondary pollution.
Invention content
In order to overcome the disadvantages mentioned above of the prior art, the object of the present invention is to provide a kind of composite type artificial wetland rubbish to fill out
Percolate filtration system is buried, with high pressure cleaning plant, avoids clogging, ensures that pollutant dispels efficiency, effectively changes
The Effects of Water Quality of kind garbage loading embeading percolation liquid；The long-range sampling monitoring that can also realize water quality after filtering, reduces workload, avoids oozing
Filtrate endangers operator's health；And the problems such as smell, insect and exposure that percolate is caused effectively is evaded；Engineering structure
Compact, floor space is small；Equipped with quarantine measures, secondary pollution is avoided.
