Technical field
The present invention relates to the treating apparatus of a kind of rainwater-collecting and utilization, relate in particular to a kind of novel rainAquatic organism is detained filter.
Background technology
In recent years, the rainwater runoff pollution in the most of city of China is comparatively serious, and this has become river lake waterThe primary factor that matter worsens. The gathering ground that rain drop erosion is different, makes that pollutant in runoff increases, waterQualitative change is poor, and in runoff, contains a large amount of sediments, the heavy metal of high concentration. If runoff is without locatingManage or process not up to standard and permeate the ground, will cause heavy metal-polluted soil and toxic chemical substance content mistakeHeight, makes soil necrosis, also can cause underground water pollution. Traditional curb Water drainage system design be withThe eliminating as early as possible of rainwater is starting point, but undressed runoff rainwater directly enters downstream water body,Can cause severe contamination to water body, while rainwater forms fast rainwash and will cause fearful flood.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawingAnd embodiment, the present invention is further elaborated. Should be appreciated that described herein concreteEmbodiment only, in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, the biological filter that is detained of rainwater of the present invention comprises: comprise delaying basin body11 and the delaying basin 1 of delaying basin cover plate 12, described delaying basin cover plate 12 cover described delaying basin thisThe upper end of body 11; Be arranged on the delaying basin water inlet on described delaying basin cover plate 12; Described in being arranged onMultiple layer filter media 2 in delaying basin body 11. Described multiple layer filter media 2 comprises: be positioned at and go up mostThe cover layer 21 of layer, be positioned at intermediate layer can planting plants 8 biofiltration layer 22, be positioned underThe gravel drainage blanket 23 of layer. Horizontally embedded perforation collecting pipe 4 in described gravel drainage blanket 23, instituteState perforation collecting pipe 4 and be provided with water seepage hole 41, and its with pass the side of described delaying basin body 11The collecting pipe 5 of wall is connected.
First rainwater flows in delaying basin 1 from delaying basin water inlet, then pass through successively cover layer 21,Biofiltration layer 22 and gravel drainage blanket 23, finally flow into perforation collecting pipe 4 by water seepage hole 41In, so that by the rainwater-collecting of processing.
In a preferred embodiment of the present invention, described delaying basin water inlet comprises: be arranged on described stagnantStay pond cover plate 12 tops, for introducing described delaying basin from the rainwater of pavement gathering surface 6Delaying basin desilting mouth grate 31 in body 11; Be arranged on described delaying basin cover plate 12 sides,For the rainwater that carries silt and greasy dirt from road, parking lot or garden gathering surface 9 is introduced to instituteState the rainwater inflow entrance 32 in delaying basin body 11. The delaying basin water inlet arranging like this can be distinguishedRainwater from different gathering surfaces is introduced in delaying basin body 11 effectively, improved rainwater-collectingEfficiency.
In a preferred embodiment of the present invention, the biological filter that is detained of described rainwater also comprises verticallyBe embedded in the delaying basin overflow pipe 7 in described multiple layer filter media 2, described delaying basin overflow pipe 7Upper end is higher than described cover layer 21, and described delaying basin overflow pipe 7 is connected with described perforation collecting pipe 4.Described delaying basin overflow pipe 7 is for preventing that in the time that amount of rainfall is larger flowing into biological delay of described rainwater filtersRainwater in device is saturated and can not be filtered in time, thereby makes excessive rainfall from described delaying basinIn overflow pipe 7, drain in time, to ensure that the biological filter that is detained of described rainwater can normally move.
Described cover layer 21 is made up of bark, tree root or leaf, its be conducive to microbial growth,Organic degraded and plant absorption, fixed nitrogen and metal object also contribute to reduce runoff rain simultaneouslyThe erosion of water, effectively keeps the humidity of soil, avoids topsoil to harden and causes permeance property to reduce.
Described biofiltration layer 22 adopts the sandy soil that infiltration coefficient is large and proportioning is different, and it is mainComposition is: 60～85% sand, 5～10% organic principle, is no more than 5% clay. DescribedBiofiltration layer 22 thickness in the time adopting herbaceous plant is 250mm, thickness in the time adopting xylophytaFor 1000mm. Described biofiltration layer 22 provides enough moisture and nutrition to maintain for plant 8Its growth has larger penetrating power with the rainwater of dissolving simultaneously, is root system of plant absorption and micro-lifeThing degradable carbon hydrogen compound, metal ion, nutrients and other pollutants provide a good place.
The clean gravel that described gravel drainage blanket 23 is greater than described water seepage hole 41 by diameter forms, thisSample, gravel just can be along with rainwater flows in perforation collecting pipe 4 through water seepage hole 41. Described gravelStone diameter is no more than 50mm, and the thickness of described gravel drainage blanket 23 is 200～300mm. Described gravelStone drainage blanket 23, mainly for the protection of perforation collecting pipe 4, prevents that it from stopping up, and provides one temporarily simultaneouslyStorage area, reduce runoff volume, collected by the collecting pipe 4 of boring a hole through the rainwater of diafiltration, and warpCollecting pipe 5 enters other gathering system (not shown).
The above embodiment has only expressed embodiments of the present invention, and it describes comparatively concrete and detailedCarefully, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention. It is right to it should be pointed out thatIn those of ordinary skill in the art, without departing from the inventive concept of the premise, can also doGo out some distortion and improvement, these all belong to protection scope of the present invention. Therefore, patent of the present inventionProtection domain should be as the criterion with claims.
