Description
Technical field
The invention belongs to urban environment planning, environmental protection and green building technique fields, in particular to a kind of to have rain
The Green Roof of water retention and phosphorus removal functional.
Background technique
With the continuous quickening of Urbanization in China, the quantity size in city is sharply increased, and the scale in city is also continuous
Expanding, city Permeable stratum area sharply increases, and so as to cause urban waterlogging, greenhouse effects aggravation, city water cycle is blocked,
A series of problems, such as level of ground water declines.Urban roof usually accounts for the 20%-40% of city area, accounts for city Permeable stratum area
40%-50% is the important component of city underlying surface, is important generation and the transfer of urban storm runoff.Therefore subtract
Few roof runoff and control roof runoff pollution are of great significance.Green Roof refers to lighter weight and prevents on roof
Kind has the roof of vegetation on water layer and root resistance layer, is the earth that spreads a layer of clay above roof water barrier, then partly or entirely plants
Upper plant.Green Roof can generate a variety of benefits, including buffer heavy rain, extend roof water-proof system service life, promoted and built
Aesthetics is built, noise is reduced using the roof space, the heat-insulated thermal protective performance of raising, mitigation urban heat land effect, help, is mentioned for animals and plants
For habitat, absorbing carbon dioxide, increase bio-diversity etc..There is certain carbon to converge for the soil of Green Roof and vegetation simultaneously
Ability is conducive to the reduction of carbon dioxide in atmosphere.Therefore Green Roof is (low by BMPs (rainwater best management mode) and LID
Influence exploitation) it is widely used.But safeguard that the plant on green roof needs to add fertilizer, there is also trophism objects in soil matrix
Matter and atmospheric sedimentation make pollutant be transferred to ground, under the eluviation of rainwater, will lead to rainfall runoff in Green Roof
Containing there are many nutrient pollutants, while these rainwater can be discharged in receiving water body so as to cause water body by drainage system against rain
Eutrophication.The researchs such as Wang Shumin find that the pH value of the storm runoff of Green Roof is 7.7, and the content of total phosphorus is 0.17-
0.28mg/L.Research shows that the diffusion coefficient due to phosphorus is lower, easily deposited in surface water body, therefore phosphorus is 80% water body in lake
The controlling elements of eutrophication.It is generally acknowledged that the total phosphorus in water concentration such as lake and reservoir is greater than 0.02mg/L, then it is considered as eutrophy
The water body of change, when total phosphorus concentration is more than 0.05mg/L, algae and certain water plants will undue growths.The water body richness of Dian Chi is sought
Feedingization the study found that 67% pollution comes from pollution of area source, while city surface source is the second largest dirt in addition to agricultural area source
Dye source.Therefore need one kind that can retain the mode of construction of the Green Roof of P elements in rainwater and water to control
The pollution of area source in city alleviates water eutrophication.
Summary of the invention
The purpose of the present invention is to provide a kind of Green Roofs with rainwater retention and phosphorus removal functional, to solve roofing rain
Water runoff pollution and rainwater bring water eutrophication problem.
To achieve the above object, the invention adopts the following technical scheme:
A kind of Green Roof with rainwater retention and phosphorus removal functional, including dephosphorization region and retention area；Retention area
The side in dephosphorization region is set, is provided with barrier wall between dephosphorization region and retention area；Dephosphorization region includes vegetation plantation
Layer, soil matrix layer, aluminium sludge substrate layer, isolation filter layer and drainage blanket；Vegetation plants layer, soil matrix layer, aluminium sludge base
Matter layer, isolation filter layer and drainage blanket are set gradually from top to bottom；Retention area includes filter tank, triangle overflow weir and the day that catchments
Ditch；The side in filter tank is barrier wall, and the other side in filter tank is triangle overflow weir, and the side in filter tank is arranged in the gutter that catchments.
Further, stopping area and waterproof layer are additionally provided with below dephosphorization region and retention area；Stopping area setting exists
The top of waterproof layer, the lower section of waterproof layer are roof.
Further, the lower part of barrier wall is paliform.
Further, cover having holes are provided with above retention area；Cover having holes are reinforced concrete cover board；Retention area
Catchment gutter bottom setting rain funnel.
Further, isolation filter layer uses polyester fiber non-woven fabric；Drainage blanket is high density polyethylene (HDPE)；Stopping area is poly-
Urethane thin slice；Waterproof layer is PEC polymer membranes.
Further, the bottom in filter tank is equipped with cobblestone, and quartz sand is equipped with above the cobblestone of bottom, quartz sand
Top is equipped with cobblestone, and the cobblestone above quartz sand is greater than the cobblestone of bottom.
Further, planting on vegetation plantation layer is sedum lineare.
Compared with prior art, the present invention has following technical effect:
For the present invention using the aluminium sludge of dehydration as the P elements in aluminium sludge substrate layer removal rainfall runoff, dehydration aluminium is dirty
Mud is the by-product in the water purification process of waterworks by aluminium salt etc. as flocculant removal water pollutant, while being also dehydration aluminium
Sludge provides a kind of processing mode of new resource utilization.
Go out lower part of the water Jing Guo barrier wall of P elements of the present invention is that fence is flowed into filter tank, then passes through triangle overflow weir
The gutter that catchments is flowed to, is discharged eventually by rainwater funnel, filter tank and the gutter that catchments can effectively control rainfall runoff.
The present invention designs simple filter apparatus, and there are many weight saving than traditional sandstone drainage blanket, and can be very good
Play the filtration to rainwater.
The present invention selects the extremely strong sedum lineare of vitality, reduces dose and maintenance.
The present invention selects lightweight host material and drain bar, mitigates structural load.
