Description
Technical field
Guide of the utility model percolate from garbage filling field and landfill gas gathering system belong to the environmental protection installation field, particularly the refuse landfill treatment facility.
Background technology
Household refuse landfill sites mainly produces the pollution key element of two aspects, on the one hand is the poisonous and harmful sewage of the rubbish body high concentration of oozing out, and promptly percolate is that the main component that is produced by anaerobic fermentation is the flammable landfill gas of methane on the other hand.Therefore, percolate that household refuse landfill sites produced and landfill gas are the pollution key elements of necessary emphasis control.
At present, what finish percolate guide function in the household refuse landfill sites is the percolate guide system that is made of main french drain, a french drain, this system is arranged on the interior identical aspect of refuse landfill end liner layer, percolate is finally all collected in this guide aspect in the rubbish body, and drain into sewage regulating reservoir outside the venue by blind pipe, the ubiquitous problem of this system is: seepage flow is generally very big to the percolate concentration of bottom, the salt content height, easily at bottom precipitation, and the eyelet of silting loaded filter and geotextile causes the forfeiture of normal draining and anti-filter function.Percolate is accumulated the water level rising that can cause in the landfill yard and is caused stronger leaching in the landfill yard bottom, thereby the pollutant levels of percolate are increased, and cause the hydrostatic pressing of rubbish body bottom lining to increase, cause percolate to leak into more in the underground soil layer and cause environment pollution.Because at the bottom of the percolate guide system that main french drain, french drain constitute is positioned at, the ponding that can't in time get rid of each position of rubbish body, particularly when heavy rain, rainy season, often leak, cause the soot periphery formed and pollute because of local ponding in the landfill yard pollutes thing.
In addition, it is the landfill gas of methane that household garbage anaerobic fermentation in landfill yard produces main component, and this landfill gas has pros and cons duality.On the one hand, methane is a kind of flammable greenhouse gases, as reaching the periphery accumulation inside, causes the safety problems such as calamity or blast of lighting a fire easily, can produce greenhouse effect in the atmosphere again if be disposed to, harmful atmospheric environment; On the other hand, landfill gas is again a kind of energy of recyclable utilization, has higher calorific value.Household refuse landfill sites normally adopts the method for building the air guide gabion to come this gas of guide at present, with the control potential safety hazard, but the air guide gabion is generally separately independently gas well, do not form an apparatus system, gas guide effect is relatively poor, and the collection of unresolved landfill gas and recycling problem.
The utility model content
The purpose of this utility model provides a kind of percolate from garbage filling field guide and landfill gas gathering system, by the three-dimensional guide system of linking up is set in the rubbish body, realize the difference guide and the recycling of high pollution percolate and fermentation gas, not only favourable environment, but also the recycling of favourable resource.
The utility model purpose is achieved by the following technical solution:
Guide of this percolate from garbage filling field and landfill gas gathering system, comprise guide groove in the rubbish body, vertical guide well, the gentle pumping system of rubbish body surface gas collection pipe, characteristics are the rubble filling guide groove that the guide groove is made up of a leading emissions groove and a guide groove, vertically the guide well is made up of inner wireway and outside rubble lead layer, inner wireway is the perforation ventilating pipe, gas collection pipe is made up of a main discharge and a discharge, leading emissions groove is constructed the slope at the bottom of nearly soot, its low side port of export is connected with the sewage regulating reservoir, guide groove is constructed the different level layer slope more than leading emissions groove, construct on the vertical guide hole deviation slope of leading emissions groove to the low side correspondence by the slope high level, on a leading emissions groove and a guide groove, construct vertical guide well respectively at interval, its height is until the surface, soot, and prop up the corresponding low side of guide groove UNICOM with each aspect, leading emissions groove promptly props up guide groove UNICOM by vertical guide well and each aspect, the inner wireway upper end mouth of pipe of each vertical guide well and rubbish body surface gas collection pipe UNICOM, form three-dimensional percolate and the landfill gas guide gathering system of linking up, percolate compiles the leading emissions groove of inflow by a guide groove and the vertical guide well of different level aspect, drains into the sewage regulating reservoir through its outlet; Landfill gas then by the inner wireway of vertical guide well, through gas collection pipe, enters the gas recycle bin.
What the design's guide groove adopted is to fill the constructed irregular multiple aperture drainage device that forms by the rubble material of different-grain diameter, and its permeability is much larger than solid refuse, so have water guide and air guide function simultaneously in the rubbish body.
The design constructs at different level layer slope by constructing leading emissions groove in rubbish body bottom ramp
Guide groove, construct in the vertical guide of leading emissions groove to correspondence by high level well inclined, leading
An emissions groove and a guide groove are constructed the vertical guide well that has guide liquids and gases function concurrently respectively at interval, its height is until the surface, soot, and prop up the corresponding low side of guide groove UNICOM with each aspect, formed the liquid of three-dimensional communication, the guide system of gas thereby make leading emissions groove prop up guide groove UNICOM by vertical guide well and each aspect.Percolate in the rubbish body is through a guide groove of different aspects, vertical guide well, and guide imports leading emissions groove, and drains into the sewage regulating reservoir through its outlet, prevent that effectively percolate from building up in the bottom, in rainy season, its drain function advantage is particularly evident, is not easy to form ponding in the landfill yard; The wireway guide of fermentation gas in the rubbish body in vertical guide well is to a discharge on the face of land, soot, main discharge through its connection is sent to recycle bin again, both eliminated the potential safety hazard of landfill gas, effectively reduced greenhouse gases sky is discharged again, finished the high efficiente callback utilization of landfill gas, the guide system that the design links up by the solid that is provided with in the rubbish body, round Realization the difference guide and the recycling of high pollution percolate and fermentation gas, solved the difficult problem of household refuse landfill sites pollutant control, favorable environment, the recycling of favourable resource is a green environment engineering design of benefiting the nation and the people.
