From several apertures are longitudinally inserted with up to bottom, for adding water moisturizing.The utility model structure is simple, and design rationally, prevents from being percolated
Liquid is to subsurface wastewater infiltration system, polluted underground water source；Effectively realize that microorganism and nutriment are uniformly distributed, ventilation aeration is balanced, accelerates
Degradation speed.
A kind of microorganism heap degeneration system of petroleum hydrocarbon contaminated soil, including biological heap (4), biology heap (4) lower section
It is covered with antiseepage film (3), antiseepage film (3) both sides are equipped with gutter, and sink (9) are led in gutter；Biological heap (4) center is inserted with ventilation
It manages (2), is connect on the left of ventilation duct (2) with air blower (1), wrapped up around ventilation duct (2) by buffer layer (6)；Above biological heap (4)
Equipped with spray equipment (5), it is connected on the right side of spray equipment (5) with suction pump (8), suction pump is connect with tank (9)；Biological heap
It is (4) intermediate that there are several gaps (7)；
Preferably, the ventilation duct (2) for being inserted into biological heap goes out to set apart from bottom 20cm that there are two gas vents, and gas vent is with two layers
Gauze package, prevents from being blocked by foreign object, is filled and surrounds by buffer layer (6) around ventilation duct.Biological heap (4) is stayed from top layer to bottom
There is gap uniformly to keep the skin wet for soil, microbial inoculum and nutriment.Biological heap (4) two sides gutter is that two sides extend out more
The concave surface that is made into of antiseepage film, lead to sink (9) and collect percolate.
Compared with prior art, the utility model has the advantages that: the utility model structure is simple, design rationally, by logical
Air piping air blast, wind enter buffer layer, and wind, even into soil, makes each level soil uniformly obtain oxygen by buffer layer, with
It is grown for microorganism.Tank can fill water, mix bacterium agent, and nutriment is sprayed onto biological heap by spray equipment, passes through life
The gap that object heap center is stayed can make spray solution uniformly reach each depth of biological heap, and making it, quite object heap soil uniformly mixes.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Marked in the figure: 1- air blower, 2- ventilation duct, 3- antiseepage film, 4- biology heap, 5- spray equipment, 6- buffer layer, the hole 7-
Gap, 8- water pump, 9- sink, 10- tank.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clear, complete description.
A kind of microorganism heap degeneration system of petroleum hydrocarbon contaminated soil, including biological heap 4, biology 4 bottom of heap are laid with
There is antiseepage film 3, and biological 4 two sides of heap are equipped with gutter, gutter is connected to sink 9；The gutter generates in this way:
The antiseepage film 3 of biological 4 bottom of heap extends outwardly from biological heap two sides, and the antiseepage film extended forms the draining with concave structure
Ditch.
In the biology heap 4 separately be inserted with several ventilation ducts 2, the periphery of the ventilation duct 2 in biological heap package
Having the buffer layer 6(buffer layer can be sawdust rice husk))；These ventilation ducts 2 are connected and connect with air blower 1, on biological heap 4
Side is equipped with spray equipment 5, and spray equipment 5 is connected with suction pump 8, and the suction pump is connect with tank 10, and tank 10 is used
In dress water, mixing match microbial inoculum, nutriment and displacement of reservoir oil dispersing agent.The biology heap 4 is equipped with several in its longitudinal direction
Hole 7 separately, which uniformly keeps the skin wet for soil, microbial inoculum and nutriment.The ventilation duct 2 is apart from biology
Gas vent is offered at the position 20cm of heap bottom, the gas vent is wrapped up with gauze.
The working principle of the utility model is:
Petroleum hydrocarbon contaminated soil is dug out, the ventilation duct 2 during biological heap 4 is built by gauze package drilling is indulged
To insertion, effective sawdust filling is covered greatly as buffer layer 6, when biological heap with big casing, ventilation duct and outside outside ventilation duct 2
The big casing in outside is extracted out when 4 composting 1.5m high, buffer layer 6 is filled to 1.4m high, is buried with soil envelope to 1.5m, is then connected above
Ventilation duct 2 and blower 1 are continuously 4 oxygen of biological heap with blower 1.In biological 4 build process of heap, it is inserted into biological heap 4 several
Waddy builds completion to biological heap 4 and extracts the wooden root out, forms gap 7.The spray equipment 5 at biological 4 top of heap can be with spray water
Point, bacterium solution and nutriment, by the 4 several gaps in center of biology even into soil.The groove that biological 4 two sides of heap are formed is made
Percolate is drained into collect in sink 9 for gutter and places secondary pollution.
The method is usually used in the petroleum hydrocarbon contaminated agricultural land soil of middle low concentration, backfills soil after processing is up to standard.
