Abstract
The utility model aims at providing a go up upper cover system for landfill leachate equalizing basin. In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a go up upper cover system for landfill leachate equalizing basin which characterized in that: the upper floating cover system comprises an upper floating cover, the upper floating cover is of an integral structure formed by welding HDPE (high-density polyethylene) membranes, the upper floating cover is positioned above the regulating tank, and the periphery of the upper floating cover is connected and sealed with the edge of the regulating tank. According to the technical scheme, the method comprises the following steps: the system can effectively block odor diffusion in the regulating reservoir, is easy to operate, low in manufacturing cost, not easy to corrode and good in sealing effect.
Description
Technical field
The utility model relates to garbage disposal, specifically relates to a kind of come-up convering system that is used for the percolate regulating reservoir.
Background technology
Along with the continuous expansion of city size, the domestic waste generation is increasingly high.Seepage control measure handled and done to the national regulation consumer waste landfill percolate must centralized collection.Percolate from garbage filling field drains into regulating reservoir through collecting pipe, and the common design area of regulating reservoir is bigger, the opened type structure.So leachate equalization basin is the important pollution sources that landfill yard produces foul smell, the foul smell of its generation flows with air and influences surrounding environment.Along with the enhancing of the environmental protection meaning, must effectively control these foul smell, adopt regulating reservoir is added a cover.Because the regulating reservoir area is big, span is big, if adopt steel work to build lid, its cost is high, and sealing effectiveness is poor, and steel work is corroded under sewage and foul smell environment for a long time easily.
Summary of the invention
The purpose of the utility model provides a kind of good seal, the uncorruptible come-up convering system that is used for the percolate regulating reservoir.
To achieve these goals; The technical scheme that the utility model adopted is: a kind of come-up convering system that is used for the percolate regulating reservoir; It is characterized in that: described come-up convering system comprises floating head; Said upward floating head is the overall structure that is welded by the HDPE diaphragm, and the said floating head of going up is positioned at the regulating reservoir top, and its periphery is connected sealing with the regulating reservoir edge.
Can be known by technique scheme: this system can effectively intercept foul smell diffusion in the regulating reservoir, its easy operating, and cost is low, is not easy to be corroded good sealing effect.
Description of drawings
Fig. 1 be water level when low the utility model in the cross-sectional schematic of plummet direction;
Fig. 2 be water level when high the utility model in the cross-sectional schematic of plummet direction.
The specific embodiment
A kind of come-up convering system that is used for the percolate regulating reservoir; Like Fig. 1, shown in 2: described come-up convering system comprises floating head 10; Said upward floating head 10 is the overall structures that are welded by the HDPE diaphragm; The said floating head 10 of going up is positioned at regulating reservoir 20 tops, and its periphery is connected sealing with regulating reservoir 20 edges.Being equipped with impervious barrier 21 on the regulating reservoir 20, is percolate on the impervious barrier 21, floating head on this 10 is placed on the percolate liquid level of whole regulating reservoir 20; Last floating head 10 can the fluctuation along with SEA LEVEL VARIATION; This system can effectively intercept foul smell diffusion in the regulating reservoir, its easy operating, and cost is low; Be not easy to be corroded good sealing effect.
Described HDPE diaphragm is that thickness is two light face HDPE diaphragms of 2.0mm.
Described floating head 10 upper epidermiss of going up are provided with gravity pressure pipe 11, and following top layer is provided with ball float 12, and said ball float 12 is positioned at 11 liang of side positions of gravity pressure pipe.Gravity pressure pipe 11 is set in the middle of last floating head 10 upper epidermiss; Gravity pressure pipe 11 when water level rises on floating head 10 just be forced out U type groove; The high state of low periphery is convenient to collect rainwater and guide gas in the middle of forming, and gravity pressure pipe 11 passes through 2.0mmHDPE film band binding solid welding on last floating head 10 films.Along with the rising of water level, utilize the buoyancy of ball float 12 will go up floating head 10 picking-ups, go up like this and just form the gap between floating head 10, ball float 12 and the water surface, and as gas channel.
Described going up between floating head 10 and the regulating reservoir 20 is provided with discharge 13, and said discharge 13 is along regulating reservoir 20 inboard arranged around one circles.Thereby can the collecting methane of percolate regulating reservoir be got up; While can also be avoided the floating head edge to contact with liquid level and cause the blocked phenomenon of gas passage.
Described regulating reservoir 20 edges are provided with anchoring ditch 30, described go up floating head 10 through bolt in anchoring ditch 30 bottoms realizing the sealing of itself and regulating reservoir 20, be positioned at described anchoring ditch 30 on floating head 10 above also be cast with concrete 31.Be beneficial to the sealing that guarantee to go up floating head and regulating reservoir edge so more, prevent that sewage and being diffused in the external environment of foul smell go in the regulating reservoir.
Be provided with between described gravity pressure pipe 11 and the last floating head 10 and prevent the film pad of gravity pressure pipe to last floating head wearing and tearing, said gravity pressure pipe 11 both sides also are provided with cystosepiment 14.Cystosepiment 14 plays can increase gravity pressure pipe 11 both sides buoyancy function; Like this when water level is higher gravity pressure pipe 11 just can with on floating head 10 extrude U type grooves, rather than V-shaped groove, its guarantees the degree of depth of U type groove; Make it to form passage, be beneficial to and collect rainwater and guide gas.
Said ball float 12 is provided with some row along last floating head 10 endosexines, every column pitch 50cm, and described every row are made up of column unit, and described column unit is combined by 2 ball floats 12, and described ball float 12 connects through anticorrosion rope.So just can be along with the rising of water level, utilize the buoyancy of ball float 12 will go up floating head and evenly hold up, help forming the exhaust passage, thereby foul smell guide in the sewage is gone out.
Offer gas collection hole on the described discharge 13.Discharge 13 adopts the DN200HDPE pipeline tapping to form, and is 16mm through on horizontal pipe, opening diameter, and spacing is the 150mm gas collection hole, makes it evenly to be interspersed.The biogas that regulating reservoir produces is deflated the pipeline centralized collection and is communicated to follow-up gas treatment equipment such as mix flare burner etc. through discharge 13.
Through above-mentioned measure can realize the floating fixing and sealing of convering system; The gas that sewage produces in the regulating reservoir can't pass the floating head film and evaporate in the environment on every side; Air can not get under the floating head film yet, and rainwater can not flow in the regulating reservoir, has also reduced the treating capacity of sewage.And this system can collect biogas that regulating reservoir produces, prevent that rain is dirty mixes also, and possesses and prevent that people and animals etc. from falling into the safety prevention measure of leachate equalization basin.
