Abstract
The utility model relates to a leachate drainage system for a hazardous waste safety landfill, wherein a leachate collecting pipe and a leachate drainage bushing are directly paved along a first layer of antiseepage film. The upper end of the leachate drainage bushing enters a pump house and the lower end of the leachate drainage bushing is arranged inside a leachate collecting tank. The bottom of the leachate drainage bushing is connected with the leachate collecting pipe in the leachate collecting tank. A leachate drainage pipe is arranged inside the leachate drainage bushing. The upper end of the leachate drainage pipe is connected with a diaphragm pump in the pump house. The lower end of the leachate drainage pipe equipped with a liquid level gauge reaches the bottom of the leachate collecting tank. The leachate in the leachate collecting tank is discharged out of the landfill via the leachate drainage pipe. A second layer of antiseepage film is paved under the first layer of antiseepage film. The leachate is discharged out of the landfill via a composite HDPE drainage screen arranged between the two layers of antiseepage films. According to the utility model, the leachate collecting tank is arranged at the bottom of a pit and the drainage bushing is directly paved on the antiseepage films along the pit slope. Therefore, the optimum antiseepage effect is ensured and the safety of the hazardous waste safety landfill is also improved.

Technical field
The utility model belongs to the waste reduction and disposal equipment field, relates to a kind of hazardous waste security landfill field percolate guide system, is particularly suited for hazardous waste security landfill field.
Background technology
The raising of Along with people's environmental consciousness; Domestic hygiene risk refuse security landfill field and the safety risk refuse security landfill field of disposing hazardous waste of having built a lot of disposal household garbages in nearly ten years; Basically large, medium and small city all has hygiene risk refuse security landfill field, and most provinces and regions have a hazardous waste security landfill field at least.Because the advancing of epoch, industrial expansion, the progress of science has been used a lot of new materials in the design process of these hazardous waste security landfill fields, HDPE antiseepage film for example, composite earthwork net, bentonite pad etc.But some shortcoming also aspect the innovation of technology mainly shows the guide aspect of percolate, should consider how to make safer, the more insurance aspect of seepage control system.No matter because be household garbage or industrial dangerous waste; The percolate composition that produces in its landfill process becomes increasingly complex, and toxicity is increasing, in case the leakage of percolate takes place in hazardous waste security landfill field; Get into underground water or surface water; Will seriously influence soil, biology, so existent environment of people, so the construction of hazardous waste security landfill field must be guaranteed the anti-seepage effect of percolate.
Usually percolate discharge guiding pipe is crossed antiseepage film in the design of the field of hazardous waste security landfill in the past; But because bottom, hazardous waste security landfill field load is very big; The possibility that foundation settlement is often arranged, this may cause percolate discharge guiding pipe to tear antiseepage film, stays hidden danger for the seepage of percolate.
Summary of the invention
The utility model problem to be solved is; Overcome the deficiency of prior art, a kind of hazardous waste security landfill field percolate guide system is provided, with leachate collection to a leachate collection pond, the end; The guide sleeve pipe is laid on the antiseepage film along the slope, hole; The guide of percolate does not penetrate antiseepage film, guarantees that seepage control system is in best antiseepage state, has improved the safety of hazardous waste security landfill field.This guide sleeve bottom links to each other at collecting pit with the leachate collection pipe; In the guide sleeve pipe percolate discharge guiding pipe is installed; Content gauge is equipped with in the discharge guiding pipe lower end, and the percolate in its hole end collecting pit is discharged outside the venue through the percolate discharge guiding pipe that links to each other with diaphragm pump, and the discharging of percolate realizes automation; The danger of rupture of membranes has been avoided in the guide of percolate like this, guarantees that seepage control system is in best antiseepage state.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of hazardous waste security landfill field percolate guide system that provides according to the utility model; Comprise leachate collection pipe, percolate guide sleeve pipe, percolate discharge guiding pipe and antiseepage film; Described leachate collection pipe is laid in the leachate collection cobble ditch, is equipped with the first floor antiseepage film under the leachate collection cobble ditch, and percolate guide sleeve pipe is directly laid along the first floor antiseepage film; Percolate guide sleeve pipe upper end gets into pump house; Percolate guide sleeve pipe lower end links to each other in the leachate collection pond with the leachate collection pipe, in the percolate guide sleeve pipe percolate discharge guiding pipe is installed, and the percolate discharge guiding pipe upper end links to each other with pump house septation pump; The percolate discharge guiding pipe lower end is arrived at the bottom of the leachate collection pond, and content gauge is equipped with in the percolate discharge guiding pipe lower end.
It is to take following technical scheme further to realize that the utility model solves its technical problem:
Be equipped with compound HDPE drainage network under the aforesaid first floor antiseepage film, compound HDPE is equipped with second layer antiseepage film below the drainage network, is equipped with earth blanket below the second layer antiseepage film;
Be equipped with the leachate collection boulder bed on the aforesaid first floor antiseepage film, between first floor antiseepage film and leachate collection boulder bed, be equipped with nonwoven.
The utility model compared with prior art has significant advantage and beneficial effect:
Because utility model adopts the end, hole, hazardous waste security landfill field that the leachate collection pond is set, dark 0.6 meter of pond has enough water storage capacity.Percolate guide sleeve pipe does not penetrate the first floor antiseepage film, but is laid on the antiseepage film of hole inner slope, guarantees that seepage control system is in best antiseepage state, has improved the safety of hazardous waste security landfill field.The percolate discharge guiding pipe lower end is equipped with content gauge, and automatic control is accomplished in the guide of percolate.The guide of percolate need not be conventional submersible pump, only with the diaphragm pump in the pump house, reduced maintenance cost.And diaphragm pump can be used for the running of a plurality of percolate discharge guiding pipes simultaneously.
The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1, leachate collection pipe 2, first floor antiseepage film 2 ', second layer antiseepage film 3, percolate guide sleeve pipe 4, leachate collection pond 5, percolate discharge guiding pipe 6, diaphragm pump 7, content gauge 8, percolate 9, pump house 10, soil 11, earth blanket 12, compound HDPE drainage network 13, leachate collection cobble ditch 14, nonwoven 15, leachate collection boulder bed 16, refuse landfill district
