Description
Technical field
The method for filling old rubbish recovery vegetation in garbage landfill field is utilized the present invention relates to a kind of.
Background technique
With the sustained and rapid development of social economy, its limitation of the Sanitary Landfill Technology exposed day by day of domestic waste
Property: (1) refuse landfill takes up a large area, and site selection of landfill difficulty has become universal phenomenon；(2) a large amount of overburden soil sources are needed,
Large amount of land resources are not only consumed, but also largely reduce the effective storage of refuse landfill；(3) garbage loading embeading operation
Periphery ecoscape is seriously affected, the surface revegetation of landfill yard ending is slow.Currently, landfill yard revegetation slowly causes
The a large amount of land resource of refuse landfill is idle, causes the serious waste of land resource；(4) since large area landfill soil is naked
Dew is idle, and water retention in soil is poor, lacks bifurcated characteristic of removing contamination, and causes percolate from garbage filling field yield to increase, foul gas
It is directly discharged in atmosphere, it has also become surrounding area water environment and the important pollution sources of atmospheric environment.Therefore, the plant of refuse landfill
It is resumed and has become current critical issue urgently to be solved.
Summary of the invention
It is an object of the invention to overcome defect of the existing technology, a kind of utilize is provided and fills old rubbish recovery rubbish
The method of landfill yard vegetation.
To achieve the goals above, The technical solution adopted by the invention is as follows:
The method for being restored vegetation in garbage landfill field using the old rubbish of landfill of the invention, is included the following steps:
(1) the big part building waste filled in old rubbish is separated, laying is in the refuse landfill table to have closed
Face is added humic acid and soil in the remaining old rubbish of landfill, is uniformly mixed, is covered on building waste, aging
120-240h and every 12-30h turning is primary, obtains planting soil layer after aging；
(2) straw or like vegetable is planted in planting soil layer, plantation density is 12000-20000 plants/acre；
(3) first time harvesting is carried out after planting 30-60 days to the straw or like vegetable of step (2), is hereafter entered to straw or like vegetable
Continue to gather in after maturity period, this process maintains 5-10 months, and supplements humic acid in soil layer after each harvesting；
(4) straw or like vegetable terminate last time gather in after, soil layer is turned over, ditch, in ditch be added humic acid,
The mixture of filter mud of sugar refinery, plant ash and soil, then ridging, plants vegetation, and excavate drainage canal for rainwater at soil layer edge
It drains into except landfill yard.
Preferably, it is 3-6:6-20 that residue described in step (1), which fills old rubbish and the mass ratio of humic acid, soil:
8-15。
Preferably, step (1) described planting soil layer with a thickness of 40-70cm.
Preferably, straw or like vegetable described in step (2) be clover, beggar-ticks, black nightshade, argy wormwood, rye grass, in vetiver
Any one or mixture more than two.
Preferably, the magnitude of recruitment of step (3) described humic acid is 30-70kg/ mus.
Preferably, the mass ratio of humic acid, filter mud of sugar refinery described in step (4), plant ash and soil is 3-15:10-25:
2-5:10-25。
Preferably, vegetation described in step (4) be "Hur" mulberry, ramie, castor-oil plant, corn, willow, sunflower, rape, barley,
Any two kinds in oat, when plantation, different vegetation was planted every ridge.
Preferably, the humic acid is mineral resources humic acid.
The present invention is by adopting the above-described technical solution, have the advantages that
1, the present invention will be used as soil matrix after the old rubbish of the decomposed landfill of spontaneous fermentation is mixed with humic acid, soil
Be covered in refuse landfill surface, contain more heavy metal ion in old rubbish, in plantation can enriching heavy metal ion grass
Class plant, such as vetiver, rye grass, rapidly, resistance and fertility are strong, and biomass can be increased sharply, and can have for growth
Effect absorbs the heavy metal ion in Enriching soil matrix, rehabilitating soil.Secondly, containing mineral resources humic acid in soil matrix, contain
Compared with multi-functional group, such as carboxyl, alcoholic extract hydroxyl group, phenolic hydroxyl group, carbonyl and methoxyl group, there is stronger complexing, it can be with soil ring
Metal ion in border interacts, and promotes plant to be absorbed, further promotes the heavy metal in plants enriched soil
Ion, therefore reach the double action for promoting plant growth, effective rehabilitating soil.
2, secondly, the content of beary metal in soil can be greatly reduced after carrying out weeds plantation in 5-10 months and gathering in, then
Industrial crops, such as corn, sunflower are planted, and are interplanted, different industrial crops absorb different heavy metals to reparation
Ion such as the copper, cadmium and zinc of barley enduring high-concentration, and is accumulated in stem, corn be suitable for having lead, zinc, cadmium pollution soil,
By interplanting the heavy metal ion that can be absorbed again in soil.First plantation weeds plant economic crops again, can both shorten and fill out
The restoration of the ecosystem period of field is buried, and can produce economic benefit, overcomes existing time length, the investment for restoring vegetation in garbage landfill field
Greatly, the few problem of output.
3, after tested, before and after plantation vegetation, the heavy metal ion content in soil matrix has significant change, and plants economic make
After object 1 year, the cadmium ion in soil matrix reduces 89.06%, and lead ion reduces 82.04%, and mercury ion reduces 79.54%, arsenic
Ion reduces 68.32%, and chromium ion reduces 73.89%, and soil remediation effect is obvious, and vegetation coverage is 95% or more, this hair
It is bright to be created condition for extensive effectively change refuse landfill landscape and promotion revegetation.
4, the old rubbish that the city of the invention that can gradually move is stacked or filled over the years, improves urban ecological environment, concedes
Garbage mountain and the occupied soil of landfill yard reasonably utilize valuable land resource again, benefit the society and the people, kind
Significant economic benefit can be obtained by planting industrial crops, convenient for attracting the investor to participate in the place of original garbage mountain and the old rubbish of landfill yard
It sets, mitigates government burden strong operability；Land resource is saved, plant survival rate is high, can guarantee that refuse landfill sealing covers
The quality of lid greatly improves the environment of refuse landfill, has good economic, society and environmental benefit.
