Abstract
The utility model provides a kind of compact simplified refuse landfill sealing exhaust level, landfill yard is from bottom to top successively including drainage blanket, vegetation soil layer, vegetable layer on house refuse layer, new material exhaust level, HDPE film, film, air guide gabion and exhaust pipe are additionally provided in the landfill yard, it is characterised in that：The new material exhaust level is made of domestic birds and animals excrement, plant fiber end, water, rubble, and the new material exhaust level is covered in the waste layer after carrying out heap body shaping.The utility model is that the organic matters such as domestic birds and animals excrement are used as exhaust layer material by using main component, meets waste utilization, energy-saving and emission-reduction, the demand for accelerating Landfill Stabilization Rate, has very strong realistic meaning, belong to restoration of the ecosystem field.
Description
Technical field
The utility model is related to a kind of restoration of the ecosystem field more particularly to a kind of compact simplified refuse landfill sealing exhausts
Layer.
Background technology
Due to being constrained by the level of economic development, the informal landfill in numerous cities, which is not taken, effectively to be prevented in China
Shield measure, house refuse is in degradation process, air, underground water and soil around exhaust gas, waste water and the residue contamination of generation
Earth.Meanwhile the development in periphery cities and towns makes these former suggestion refuse landfills far from cities and towns be close to around cities and towns, simple waste
Landfill yard becomes a serious pollution source, and directly generating a large amount of waste water,waste gas and industrial residue to nearby residents pollutes.For above-mentioned
Situation, each relevant ministries and commissions of the central government and country have put into effect some policies and countermeasure in succession, carry out control to storage rubbish,
Such issues that attempt to solve.And the engineering means of such issues that as main solution are standardization closing, standardize closing
Have in major project the shaping of heap body, landfill-gas collecting and processing, Closure cover, earth's surface water management, leachate collecting and disposal and
Conveyance system.It is Closure cover that compact simplified refuse landfill standardization, which closes and reduces the major project means of pollution, but these
There is also following deficiencies for facility：One, material cost is high, can not gather materials on the spot；Two, covering material can not reduce landfill gas production
Amount is only merely passively to be filled；Three, covering material can not accelerate landfill yard garbage degradation.Therefore it needs a kind of novel
Simple Landfill Closure exhaust level solves these problems.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of compact simplified refuse landfill sealing exhaust level, fill out
Field is buried from bottom to top successively including drainage blanket, vegetation soil layer, vegetation on house refuse layer, new material exhaust level, HDPE film, film
Layer, it is additionally provided with air guide gabion and exhaust pipe in the landfill yard, it is characterised in that：The new material exhaust level is by domestic birds and animals
Excrement, plant fiber end, water, rubble composition, the new material exhaust level are covered in the waste layer after carrying out heap body shaping.
In the above-mentioned technical solutions, a kind of compact simplified refuse landfill sealing exhaust level, it is characterised in that：Institute
It states in new material exhaust level, stone sizes are about d=30-40mm, and rubble is about 10-15% in the content of mixing material.
In the above-mentioned technical solutions, a kind of compact simplified refuse landfill sealing exhaust level, it is characterised in that：Institute
It states in new material exhaust level, mixing material thickness is 40cm, while top covers HDPE film.
In the above-mentioned technical solutions, a kind of compact simplified refuse landfill sealing exhaust level, it is characterised in that：Institute
It states in new material exhaust level, the domestic birds and animals excrement is pig manure, cow dung, chicken manure, and the plant fiber end is stalk end, saw
End.
The utility model has the beneficial effects that main component is used to substitute rubble conduct for organic matters such as domestic birds and animals excrement
It is vented layer material, there is good application range in the closing of small town Simple Landfill Site, there is waste utilization, energy saving
Emission reduction accelerates the advantages of Landfill Stabilization Rate, has very strong realistic meaning.

Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment 1：
Heap body shaping is carried out to the landfill yard 11, so that it is met draining and the requirement of heap body stability, and carry out place
Smooth, the preparation process of the new material exhaust level 2 includes：S1, it takes local pig manure to carry out physico-chemical analysis, obtains its physics and chemistry
Data；S2, pig manure, stalk end and water is taken to be sufficiently mixed, it is 15 that its carbon-nitrogen ratio is adjusted by way of adding stalk end：
1, it is 40% that moisture content is adjusted by way of adding water, is conserved 12 hours in ventilating and cooling place；S3, take it is a certain amount of a diameter of
The rubble of 40mm, mixes with above-mentioned material, and rubble ratio accounts for the 15% of total volume ratio；S4, by material pile obtained in S3 extremely
Fill heap body, be compacted and carry out surface smooth, rapidly cover HDPE film 3, then carry out drainage blanket 4 on film, vegetation soil layer 5,
The covering of vegetable layer 6, at this time Closure cover completion.
Embodiment 2：
Embodiment 2 is substantially the same manner as Example 1, difference lies in：S2, it takes pig manure, sawdust and water to be sufficiently mixed, leads to
Cross addition stalk mode come adjust its carbon-nitrogen ratio be 18：1, it is 43%, Yu Tong that moisture content is adjusted by way of adding water
Wind shady place conserves 12 hours；S3, the rubble for taking a certain amount of a diameter of 35mm, mix, rubble ratio accounts for totality with above-mentioned material
The 13% of product ratio.
Embodiment 3：
Embodiment 3 is substantially the same manner as Example 1, difference lies in：S2, cow dung, stalk end and water is taken to be sufficiently mixed,
It is 20 that its carbon-nitrogen ratio is adjusted by way of adding stalk：1, it is 45% that moisture content is adjusted by way of adding water, in
Ventilating and cooling place conserves 12 hours；S3, the rubble for taking a certain amount of a diameter of 30mm, mix, rubble ratio accounts for always with above-mentioned material
The 10% of volume ratio.
Compared with previous Closure cover material, the exhaust level of material formation realizes gathers materials on the spot the utility model, realizes
Waste utilization to poultry manure and plant fiber end, reduces the utilization of crushed stone material, greatly reduces construction investment.Pass through this
The microorganism and special degradation process that material generates, can effectively reduce the discharge 5- of poultry manure and junk-heap body greenhouse gases
15%.The abundant microorganism contained in excrement can be that the degradation of landfill yard lower part rubbish brings Beneficial Effect, shorten Landfill Stabilization
It fixes time.After implementation, the organic matter in first six months exhaust level can gradually degrade, and realize waste utilization；After six months, exhaust level
Interior material can become loose porous structure because of degradation, can be as the gas passage arranged outside landfill gas.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
