Description
Technical field
The present invention relates to a kind of roof greening material, a kind of greening roof water conservation water purification blanket and its system are specifically related to
Make method, belong to building material field.
Background technology
The structure of greening roof is generally structure sheaf, waterproof layer, sluicing layer, filter layer, plantation layer and vegetation thereon.
In existing technology, plantation layer is typically using the base material manually prepared, usually coarse particulate material such as haydite, river sand and organic
Matter, fertilizer, the mixture of table soil.Filter layer uses textile product, and effect is that plantation layer thin particulate matter is stopped in filtering, prevents soil
Earth is lost in.To improve roof greening drought resisting problem, patent " filter water retention carpet for roof greening " patent No. is occurred in that in recent years
ZL200920087198.6, although solve the problem of roof greening water and soil conservation, but it is dirty not solve Roof Runoff water still
The problem of dye.Due under urban environment particulate in air often contain heavy metal, organic pollution can also be descended slowly and lightly with rainwater to
On roof, together with plantation base material in fertilizer, organic matter and and grain fraction, can discharge pollutant in rainfall, cause roofing
Runoff heavy metal, nitrogen phosphorus, organic pollution are exceeded.Foreign study shows, the roof runoff quality at green roof initial stage is poor, past
It is past to need purified treatment.
To improve the water quality of Roof Runoff, it is necessary to which a kind of replace traditional greening room with the filter layer that water conservation water purification is acted on
The filter layer on top.
The content of the invention
It is net with water conservation that the technical problems to be solved by the invention are to provide a kind of greening roof with the effect of water conservation water purification
Water blanket.The blanket can prevent soil loss, and some moisture can be kept again, moreover it is possible to purify roof runoff quality.
The technical problem of the present invention is solved using following technical proposals：
A kind of greening roof water conservation water purification blanket, including upper strata non-woven fabrics, middle level non-woven fabrics and lower nonwoven cloth；It is described
The fiber surface absorption being provided between upper strata non-woven fabrics, middle level non-woven fabrics in the uniform fibrous layer of thickness, the fibrous layer is concavo-convex
Rod stone clay；It is red algae powder and the mixture of activated carbon granule between middle level non-woven fabrics and lower nonwoven cloth, activity in mixture
Charcoal particle volume ratio is 20-40%；
Upper strata non-woven fabrics, middle level non-woven fabrics together, are adopted using loop bonding sewer between middle level non-woven fabrics, lower nonwoven cloth
It is sewed together with needling process；Or upper strata non-woven fabrics, middle level non-woven fabrics and lower nonwoven cloth use loop bonding sewer one
Rise.
The activated carbon granule particle diameter is 1-3mm.
The Concave-convex clay rod specific surface area is more than 300m2/g。
The a diameter of 0.3-0.5mm of red algae powder particles, red algae powder is to grind obtained powder after red algae is dried.
The preparation method that the present invention also provides above-mentioned greening roof water conservation water purification blanket, comprises the following steps：
Step 1, lower nonwoven cloth is paved smooth；
Step 2, red algae powder is well mixed with activated carbon granule, paved on lower nonwoven cloth, cover middle level non-woven fabrics
Afterwards, entirety is formed by needling process with lower nonwoven cloth；
Step 3, one side mix fiber, while water smoke is sprayed to it, then by the fiber of wetting and dry attapulgite
Clay mix 30 seconds, and dry in the air dry to face together；
Step 4, the smooth middle level nonwoven surface after being handled through step 2 that paves of fiber step 3 obtained；And on covering
Layer non-woven fabrics；
Step 5, upper strata non-woven fabrics, middle level non-woven fabrics are sewed into integral, middle level non-woven fabrics, lower nonwoven cloth with loop bonding line
Between be sewed together using needling process；Or stitched upper strata non-woven fabrics, middle level non-woven fabrics and lower nonwoven cloth with loop bonding line
Entirety is made.
In use, the present invention is arranged between plantation layer and sluicing layer in roof greening engineering.When raining, rainwater is carried
The heavy metal and organic pollution of fine grained clay and dissolving are washed away from plantation layer, a part of particle thing is retained by non-woven fabrics；It is molten
The heavy metal ion of solution is mainly adsorbed by Concave-convex clay rod and red algae powder；Organic substance in water is mainly tightly held by activated carbon；Some
Moisture is by fibers adsorption, and attapulgite also absorbs some moisture；Realize the purpose of water conservation and purification Roof Runoff.
Therefore, the invention has the advantages that：1st, it is rational in infrastructure.By setting three layers of non-woven fabrics, roof can be filtered very well
The particulate matter that greening backing is lost in；By adhering to Concave-convex clay rod layer on fiber, increase adsorption area, be conducive to decontamination
Contaminate thing；Current are conducive to the extension granular activated carbon of lower floor and red algae soil after the filtering of upper, middle level non-woven fabrics and fiber
The useful effect life-span of powder；Pollutant is by two layers of filtering and the filtering of three kinds of sorbing materials, and removal effect is good, can be net well
Change the Roof Runoff at greening initial stage.Water-absorption fiber is arranged in upper strata, also beneficial to Green Roof Plants drought resisting.2nd, raw material it is sufficient,
It is easy to process, cheap, durable in use.Service life is more than 10 years.3rd, transport and easy to use, tubular can be curled into,
It is easy to carry, the scene of also allowing for paves.4th, adaptability is good, by selecting the fiber of different materials and size, realizes different guarantors
Water requirement and service life；According to the contamination characteristics of Roof Runoff, the attapulgite for preparing variety classes, consumption and ratio glues
Soil, activated carbon granule and red algae powder, realize the optimal removal effect to pollutant in Roof Runoff.
