Description
Technical field
The invention belongs to rainwater treatment technical field, and in particular to a kind of road is used for the rainwater biology for removing removing heavy metals
Delaying basin.
Background technology
With China's expanding economy and the continuous improvement of living standards of the people, automobile comes into average family, more next
More automobiles drive into highway.Due to the discharge of vehicle exhaust, the leakage of fuel and the abrasion of tire, highway pavement rainwater footpath
The concentration of heavy metal is very big in stream, enters to be seeped into soil and migrates, can serious polluted underground water.How rainfall runoff is preferably removed
In heavy metal, be the problem of we should pay close attention to now.
Biological delaying basin is preferable to the retention effect of heavy metal, and wherein absorption of the coating to heavy metal plays a major role.
But soil filler has certain saturation cycle, the saturation cycle of filler can be extended by gathering in the method for plant, but have
Research shows that delay of the soil filler to heavy metal is generally 88%~97%, and accumulation of the heavy metal in plant only has
0.5%~3.3%, absorption of the root system to heavy metal is apparently higher than rhizome position, if so unit area in biological delaying basin
Plant products are relatively low, then realize that the regeneration of filler saturation is just highly difficult.Once soil filler saturation, will be unable to the weight in rainwater
Metal continues Adsorption.
The content of the invention
To solve problems of the prior art, it is used to remove weight it is an object of the present invention to provide a kind of road
The rainwater biology delaying basin of metal, the present invention have the heavy metal in rainwater very high removal rate, and can continue to remove rain
Heavy metal in water.
The purpose of the present invention is achieved through the following technical solutions：
A kind of road is used for the rainwater biology delaying basin for removing removing heavy metals, including perforate curb, biological delaying basin, perforation
Drainpipe, overflow well, heavy metal Filter column, impervious barrier and rain pipe, biological delaying basin are arranged on the side of perforate curb, biology
Level height at the top of delaying basin is arranged on the connection of biological delaying basin and highway not higher than the perforate on perforate curb, impervious barrier
Place；Biological delaying basin includes layer of plants, filter layer, transition zone and drainage blanket successively from top to bottom；Perforated drain pipe is arranged on row
In water layer, overflow well is arranged on the side of biological delaying basin, lower end and the rain pipe unicom of overflow well, and heavy metal Filter column is set
In the bottom of overflow well；Level height residing for heavy metal Filter column is not higher than drainage blanket, and upper end is connected with perforated drain pipe, lower end
Equipped with drainpipe, the water outlet of drainpipe is located in overflow well, and the lumen loading of heavy metal Filter column, which has, replaceable to be used to inhale
The filter core of attached heavy metal.
Transition zone and drainage blanket are disposed as side height, and the low incline structure in side, overflow well is arranged on transition zone and row
The relatively low side of water layer, level height residing for heavy metal Filter column are not higher than the level height of drainage blanket minimum point.
Perforate curb and overflow well are separately positioned on the opposite both sides of biological delaying basin.
Heavy metal Filter column is the open tubular column with upper bottom, and being arranged in parallel with several inside it from top to bottom will a huge sum of money
Belong to the partition plate that Filter column inner cavity is divided into snakelike cavity.
It is hinged between the upper bottom of heavy metal Filter column and the cylinder of heavy metal Filter column lower part.
It by granular activated carbon and sodium titanate nanofiber according to mass ratio is 25 that filter core, which is,:1 mixing being uniformly mixed
Thing.
The filler of filter layer is fine sand；Transition zone filler is coarse sand；Drainage blanket filler is gravel.
Drainpipe is equipped with the check valve prevented in aqueous reflux to heavy metal Filter column.
Beneficial effects of the present invention are as follows：
The present invention's can get up to discharge into biological delaying basin by perforate curb by the rainwater-collecting on highway, and biology is detained
Pond is filtered the rainwater being collected into by layer of plants, filter layer and transition zone, and the rainwater after filtering enters drainage blanket, perforation
Drainpipe is arranged in drainage blanket, therefore the rainwater in drainage blanket can enter perforated drain pipe by the hole on perforated drain pipe
The rainwater collected is imported heavy metal Filter column by inside, perforated drain pipe, and heavy metal Filter column adsorption filtration is fallen in rainwater
Heavy metal, then the rainwater for removing heavy metal is drained into overflow well, overflow well is filtered by the rainwater being pooled to and through heavy metal
The water of column filtering drains into rain pipe, and the water in overflow well is discharged into municipal storm sewer system by rain pipe；Due to heavy metal mistake
Level height residing for filter column is not higher than drainage blanket, therefore in the filter process of rainwater, can fully rely on gravity carry out flowing and
Filtering, without using other power, has the characteristics that energy conservation and environmental protection；The lumen loading of heavy metal Filter column it is replaceable be used to inhale
The filter core of attached heavy metal, according to experimental test data, when filter core absorption reaches saturation, can regularly replace filter core so that this hair
It is bright to continue to remove the heavy metal in rainwater.
