Description
[technical field]
The utility model relates to a kind of rainwater delaying basin, is specifically related to the biological delaying basin of the other rainwater for dephosphorization of a kind of speedway, and it is mainly used in by speedway, if landform license also can be applied to by other roads, belongs to drainage technical field.
[background technology]
In rainfall, rainwater can form runoff along road surface, has sneaked into a large amount of earth's surfaces pollutant in runoff rainwater, as organic matter, heavy metal, nitrogen phosphorus etc.If runoff now directly imports drainage system, can strengthen the load of drainage system; Meanwhile, if runoff flows directly in river course, can cause the pollution of river.In the time that rainfall is larger, rainwater directly washes away river course, also can cause the erosion in river course.How removing the pollutant in runoff rainwater, cut down rainwater peak value and flow, reduce it to receiving the impact of water body and environment below, is the problem that pay close attention to.
In facility at home and abroad, biological delaying basin is state-of-the art a kind of facility, can store rainwater with biological delaying basin, cuts down rainwater flood peak, removes some pollutants in rainwater.But biological delaying basin but can not effectively be removed the phosphorus in rainwater, so the concentration of phosphorus is still higher in biological delaying basin water outlet, when speedway rainfall runoff is discharged to after water body, still can cause the eutrophication of water body, make water environment degradation.So far, the biological delaying basin of also not finding speedway can have good removal ability to the phosphorus of rainwater.
Therefore,, for solving the problems of the technologies described above, the necessary biological delaying basin of the other rainwater for dephosphorization of speedway that a kind of advanced person is provided, to overcome described defect of the prior art.

The biological delaying basin of the other rainwater for dephosphorization of speedway of the present utility model is further set to: on described dephosphorization box, be evenly equipped with the micropore that diameter is 3mm, the spacing between micropore is 10mm; In described dephosphorization box, be filled with dephosphorization material.
The biological delaying basin of the other rainwater for dephosphorization of speedway of the present utility model is further set to: described gutter and cross aquaporin and be positioned at the not homonymy of pervious concrete casing.
The biological delaying basin of the other rainwater for dephosphorization of speedway of the present utility model is further set to: be also provided with a dash stone in a side of described biological delaying basin.
The biological delaying basin of the other rainwater for dephosphorization of speedway of the present utility model is also set to: in described pervious concrete casing, be placed with 9 dephosphorization boxes.
Compared with prior art, the utlity model has following beneficial effect: the phosphorus that the biological delaying basin of the other rainwater for dephosphorization of speedway of the present utility model carries runoff has to a certain extent carried out strengthening and removed, phosphorus removal ability is reached more than 80%, prevent from receiving the eutrophication of water body; Meanwhile, biological delaying basin stores rainfall runoff, and infiltration purifies, and has reduced downstream rainwater flow, heavy rain peak flow, and pollutant levels, rainwater directly washes away river course etc., has reduced the erosion in river course.

[specific embodiment]
Refer to Figure of description 1 to shown in accompanying drawing 4, the utility model is the biological delaying basin of rainwater for dephosphorization by a kind of speedway, and it is mainly made up of several parts such as low curb 1, mistake aquaporin 2, biological delaying basin 3, pervious concrete casing 4, dephosphorization box 5 and gutters 6.
Wherein, described low curb 1 is connected with speedway 8, and it is for collecting the rainwater on speedway.
Described aquaporin 2 one end of crossing are connected with low curb 1, and the other end is connected with biological delaying basin 3, thereby the rainwater on speedway is entered in biological delaying basin 3.This is crossed aquaporin 2 and is U-shaped structure, and it is made up of the permeable boulder bed 21 on upper strata and the geotechnological layer of cloth 22 of lower floor.
Described biological delaying basin 3 is of a size of 3000mmx3400mm, and it comprises one deck filter material layer 31 and one deck water storage boulder bed 32 from top to bottom, and wherein, described water storage boulder bed 32 outer wrapping one deck geotechnique layer of cloths 33, to avoid bottom soil to sneak into water storage boulder bed 32.Also be provided with a dash stone 7 in a side of described biological delaying basin 3.
Described pervious concrete casing 4 is arranged in biological delaying basin 3, and biological delaying basin 3 is separated into left and right two parts.This pervious concrete casing 4 adopts pervious concrete to make, and has very high permeable effect.
Described dephosphorization box 5 is positioned in pervious concrete casing 4.In the present embodiment, in described pervious concrete casing 4, be placed with 9 dephosphorization boxes 5.On described dephosphorization box 5, being evenly equipped with diameter is the micropore 51 of 3mm, and the spacing between micropore 51 is 10mm; In described dephosphorization box 5, be filled with dephosphorization material (not shown).
Described gutter 6 is arranged on the bottom of biological delaying basin 3.This gutter 6 and excessively aquaporin 2 are positioned at the not homonymy of pervious concrete casing 4.
The design principle of the biological delaying basin of the other rainwater for dephosphorization of speedway of the present utility model is as follows: in the time of rainfall, speedway rainwater forms runoff, is flowed to low curb 1, enters biological delaying basin 3 through the U-shaped aquaporin 2 of crossing.In biological delaying basin 3, after the bed of material 31 is processed after filtration, rainwater is stored in water storage boulder bed 32.Rainwater storage is after certain altitude, and meeting horizontal permeation, passes pervious concrete casing 4 and dephosphorization box 5 from a side, after the dephosphorization material in dephosphorization box 5 is processed, flow out from pervious concrete casing 4 opposite sides, by this process, the removal that strengthened of the phosphorus in rainwater.The rainwater after phosphorus is removed in strengthening, stores at opposite side, when after the full biological delaying basin 3 of storage, can cross dash stone 7 overflow discharges and enter surface water body, also can discharge by gutter 6.Reduce while making water outlet phosphorus concentration can not meet water body requirement when falling phosphorus kit function, can manually take out replacing dephosphorization material wherein.
The above specific embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
