Abstract
A system for shunting rainwater and sewage in a reservoir area above the crest elevation of a valley type refuse landfill comprises a refuse landfill area, a reservoir area foundation, a reservoir area side slope, an anchoring platform arranged on the reservoir area side slope and an anchoring ditch formed in the anchoring platform. The reservoir area foundation is covered with an impermeable layer, a leachate guiding and discharging pipe is laid on the impermeable layer, a zoned dam is arranged on the impermeable layer in a downstream area and the leachate guiding and discharging pipe, the refuse landfill area is arranged in the downstream area of the zoned dam, a side slope drainage channel is arranged in the anchoring ditch of the anchoring platform on the reservoir area side slope located in the upstream area of the zoned dam, the leachate guiding and discharging pipe located under the zoned dam is a solid pipe, the leachate guiding and discharging pipe located at the upstream area of the refuse landfill area and the zoned dam is a floral pipe, and a valve is arranged at the position where the solid pipe at the position of the upstream slope toe of the zoned dam is connected with the floral pipe at the high position of the solid pipe. The problem that rainwater and sewage of the reservoir area in the partial region where the reservoir bottom elevation of the refuse landfill is higher than the crest elevation of a refuse dam cannot be shunted and accordingly all rainwater permeates into a refuse dump body to be converted into leachate is solved, and the system is simple in structure and reliable in effect.
Description
Technical field
The present invention relates to a kind of dirty separate system of rain of gully type refuse landfill, be particularly applicable to that cheuch is long and narrow, bottom of the reservior longitudinal gradient is comparatively large and the dirty separate system of the rain of the above reservoir area of gully type refuse landfill crest elevation of vertical partitioning can be adopted.
Background technology
The basic function of refuse landfill be the effect of laying impervious barrier structure by place surrounding by garbage loading embeading thing and surrounding formation completely isolated, form the independent and environment closed of refuse landfill, and then stop percolate to permeate the ground to pollute underground water around landfill yard.Moisture and the rainwater of the moisture that the source of percolate has rubbish decompose themselves to produce, rubbish infiltrates the sewage produced, and rainwater infiltration is the main cause that percolate produces in a large number, leachate generation causes greatly treating capacity large, also makes that the expense of percolate process is corresponding to be increased.If by refuse landfill rain dirty separate system the rainwater produced within the scope of landfill district effectively can be separated and not by refuse pollution, garbage loading embeading is directly discharged outside the venue by rainwater guide system, reach the object of rain dirt shunting, just percolate output be can greatly reduce, and then percolate treating capacity and disposal cost reduced.
The common practice of conventional garbage landfill yard is: landfill yard elevation every 5 ~ 10m interval has corresponding anchored platform to design.If every grade of anchored platform can be utilized and build slope drainage canal in conjunction with anchoring groove, and build subregion dam in the bottom of the reservior of the identical elevation of anchored platform, then the rainwater in anchored platform and the above region of subregion height of dam journey at the same level just can pass through the interception of subregion dam and slope drainage canal, cross waste dam dam crest by escape canal and directly discharge garbage loading embeading outside the venue, and be unlikely to flow in reservoir area, downstream landfill waste and change percolate into, cause the increase of leachate generation, therefore crest elevation above reservoir area in bottom of the reservior can arrange the object that the rain dirt shunting facilities such as corresponding subregion dam reach the rain dirty separate system rain dirt shunting of each subregion according to the quantity of anchored platform.The present invention proposes based on above mentality of designing just.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of technically reliable, easy construction, realizes the dirty separate system of rain of the above reservoir area of gully type refuse landfill crest elevation of rain sewage separation.The dirty separate system of this rain is applicable to gully type refuse landfill, is specially adapted to that cheuch is long and narrow, bottom of the reservior longitudinal gradient is comparatively large and adopts the gully type refuse landfill of vertical partitioning.
It is as follows that the present invention solves the problems of the technologies described above taked technical scheme: the dirty separate system of the rain of the above reservoir area of a kind of gully type refuse landfill crest elevation, comprises the anchoring groove that garbage loading embeading district, basis, reservoir area, side reservoir slope, the anchored platform of side reservoir slope setting and anchored platform are arranged; It is characterized in that: reservoir area is covered with impervious barrier above basis, percolate discharge guiding pipe is laid with above impervious barrier, subregion dam is provided with above the impervious barrier of downstream area and percolate discharge guiding pipe, downstream, subregion dam arranges garbage loading embeading district, on the side reservoir slope of upstream, subregion dam anchored platform anchoring groove in be provided with slope drainage canal, the percolate discharge guiding pipe be positioned at below subregion dam is real pipe, the percolate discharge guiding pipe of garbage loading embeading district and upstream, subregion dam is floral tube, and the floral tube joint that the real Guan Yuqi at toe place, upstream, subregion dam is upper arranges valve.
Existing gully type landfill yard elevation every 5 ~ 10m interval has corresponding anchored platform to design, and tamps after the anchoring groove anchoring of anchored platform impervious barrier with sandy soil rubble etc.The present invention makes full use of slope anchorage platform, slope drainage canal is provided with in anchored platform anchoring groove, subregion dam is provided with in the bottom of the reservior of elevation identical with anchored platform, subregion dam is arranged with real pipe percolate discharge guiding pipe, and the joint of the real pipe percolate discharge guiding pipe floral tube percolate discharge guiding pipe upper with it of upstream, subregion dam toe arranges gate valve.During the landfill waste of reservoir area, downstream, subregion dam, by the closedown of gate valve, subregion dam and slope drainage canal to the interception of upstream rainwater, slope drainage canal to the guide of interception rainwater, the rainwater of subregion dam and slope anchorage platform upstream directly can be discharged garbage loading embeading outside the venue by slope drainage canal.Therefore, the above reservoir area of gully type refuse landfill crest elevation can arrange the rain dirt shunting facilities such as corresponding subregion dam according to the quantity of anchored platform, reaches the object utilizing the dirty separate system of the rain of each subregion to realize rain dirt shunting.
Technical scheme provided by the invention, be applicable to that cheuch is long and narrow, bottom of the reservior longitudinal gradient is comparatively large and adopts the gully type refuse landfill of vertical partitioning, refuse landfill bottom of the reservior elevation arranges the dirty separate system of rain higher than the reservoir area rainwater of waste dam crest elevation subregion by the present invention and upstream rainwater is directly discharged refuse landfill.
The invention solves refuse landfill bottom of the reservior elevation all to infiltrate junk-heap body higher than the rainwater that the reservoir area rainwater of waste dam crest elevation subregion, sewage cannot be shunted and cause and change percolate into, leachate generation is increased, and then cause the problem that percolate treating capacity is large, operating cost is high, have that structural shape is simple, easy construction, advantage reliable for effect.
