Abstract
The invention discloses a rain-sewage diversion method for garbage first-layer landfill. The method includes when first-layer landfill is performed on a landfill partition of a landfill, laying a layer of mulch on half or all of the landfill partition to ensure rain not to permeate into sewage in the landfill partition so as to retain the rain on the mulch to greatest extent; in other landfill partitions where landfill is not performed, discharging collected rain into a rain pipe duct through a changeover valve. By combing use of a cofferdam, rain-sewage diversion of first-layer landfill of the landfill can be realized effectively, and the rain on the mulch can be discharged timely, so that generation quantity of percolate in a landfill reservoir area is effectively reduced.
Description
Technical field
The present invention relates to the dirty dividing technology of the rain field of refuse landfill, specifically, the dirty shunt method of rain while relating to a kind of rubbish first floor landfill.
Background technology
At present, the dirty shunting process of the rain of traditional landfill yard adopts check dam that subregion is carried out in consumer waste filling and embedding reservoir area, by check dam, carries out the dirty shunting of rain.But landfill district area is still very large after subregion, in subregion, the dirty system of rain is integrated, and after raining, rainwater mixes as sewage, has greatly increased the treating capacity of percolate.
Summary of the invention
Technical problem to be solved by this invention is can not in landfill subregion, carry out the problem of the dirty shunting of rain and the dirty shunt method of rain when a kind of a kind of rubbish first floor landfill that can realize the dirty shunting of rain in landfill subregion is provided for the dirty shunt method of existing rain.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
The dirty shunt method of rain during a kind of rubbish first floor landfill, when landfill yard landfill subregion is carried out to first floor landfill, first by half full layer overlay mulch film in unit or whole unit of this landfill subregion, at landfill district rainwater, can not infiltrate in sewage guaranteeing, farthest rainwater is stayed on mulch film to the greatest extent, the landfill subregion that does not carry out landfill at all the other enters Storm Sewer System by switch valve by the rainwater of collection.
In a preferred embodiment of the invention, during laying plastic, film is cut out as required, overlap joint, and weld with machine, and on mulch film, place press mold material.
In a preferred embodiment of the invention, before operation every day, the mulch film having welded can be started to one jiao and carry out operation, after operation completes, film be covered again, be used as day coverlay and use.
In a preferred embodiment of the invention, in conjunction with cofferdam or hard shoulder, when working area reaches a certain amount of, one jiao of sanction of the mulch film of the not yet landfill having laid can be gone, overlay film when the part mulch film that sanction is gone can be used as the middle covering of landfill yard, by four edge laps of the mulch film after cutting out, on cofferdam or hard shoulder, the mulch film being overlapped on this cofferdam or hard shoulder with contiguous landfill subregion overlaps mutually in the mode of the overlap joint descending that goes up a slope.
In a preferred embodiment of the invention, described mulch film is that thickness is the HDPE film of 0.5～1.5mm.
The invention has the beneficial effects as follows, use the combination of covering with plastic film and cofferdam or hard shoulder, can effectively realize the rain dirt of landfill subregion and shunt and control the scope of operation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is that the mulch film of the dirty shunt method of rain of a kind of rubbish first floor of the present invention landfill is laid schematic diagram.
The specific embodiment
For technological means, character of innovation that the present invention is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
The dirty shunt method of rain during a kind of rubbish first floor landfill, referring to Fig. 1, when a landfill subregion 100 carries out first floor landfill, first half unit of this landfill subregion 100 or whole unit are completely spread to one deck mulch film 200, at the rainwater of this landfill subregion 100, can not penetrate in the sewage of whole landfill yard guaranteeing.The landfill subregion that other of whole landfill yard do not implemented landfill operation can enter Storm Sewer System by the rainwater of collection by switch valve.
It is the HDPE film of 0.5～1.5mm that laying plastic 200 of the present invention adopts thickness, i.e. high density polyethylene (HDPE) High Density Polyethylene, referred to as " HDPE ", have wear-resisting, waterproof, the advantage such as anti-oxidant, meets technique needs.
During laying, HDPE film is cut into 25 meters long, adjacent two HDPE films overlap 0.1～0.2m downstream by the gradient, adopt machine welding between HDPE film and HDPE film, and according to technological requirement, place press mold material on mulch film 200.
Whole operating area is divided according to the task amount of disposing rubbish, and as processed 1500t quantity of refuse, it is 600m that operating area this day every day overlay film area control lives in 24*25m
2in scope.Before operation every day, the mulch film by being welded together 200 can be started to one jiao and carry out operation, after operation completes, mulch film 200 be covered again, be used as day coverlay and use; Along with increasing of work layer, need separately add day coverlay, adopt the form of overlap joint that this day coverlay ridden on original mulch film 200, push down with press mold material.
When working area reaches a certain amount of, one jiao of sanction of the mulch film 200 of the not yet landfill having laid can be gone, overlay film when the part mulch film that sanction is gone can be used as the middle covering of landfill yard, realize secondary utilization, by four edge laps of the mulch film after cutting out 200, on cofferdam or hard shoulder, the mulch film being overlapped on this cofferdam or hard shoulder with contiguous landfill subregion overlaps mutually in the mode of the overlap joint descending that goes up a slope.
If rain, produce rainwater, due to the existence of film, according to the reservoir area gradient, arrange, will, at lowest bid eminence Accumulated Rainwater, the rainwater collecting must be extracted out by water pump, import Storm Sewer System or cut Great Gulch.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; invention is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
