Be provided with flase floor 6 on cover board 2 above the decanting zone A, carry particulate matter, suspended matter, floating material, nitrogen, The initial rainwater of the pollutants such as phosphorus, oil and grease enters decanting zone A through flase floor 6.Drainage bucket 7 is arranged under the flase floor 6 Side.The drainage bucket 7 is reticular structure, for intercepting the pollutions such as larger rubbish, leaf from the initial rainwater that flase floor 6 flows into Object.

In the decanting zone A, the baffle 8 extended downwardly is also set up on the cover board 2 between drainage bucket 7 and overflow wall 3.It is described The lowermost end of baffle 8 is less than the top of overflow wall 3.With the rising of water level, when water level rises to the top of overflow wall 3 in the A of decanting zone When the position in portion, rainwater then can enter filtering area B from overflow above overflow wall 3.The bottom of baffle 8 is less than the wall of overflow wall 3 Top, floating material, oil and grease are intercepted by baffle in decanting zone A, and rainwater ensures floating material, oil and grease from 8 flowing underneath of baffle Filtering area B will not be entered.

The bottom of the filtering area B is covered with gravel layer 9 and Biomedia layer 10 successively from top to bottom.There is kind on Biomedia Plant 11.

Dismountable tree pond cover board 12 is provided on cover board 2 above the filtering area B, tree pond cover board 12 is according to kind The size of plant 11 is configured in Biomedia layer 10.

Between decanting zone A and filtering area B, it is equipped with " L " the type perforated drain pipe 13 through overflow wall 3, the perforation row Water pipe 13 passes through overflow wall 3 and stretches into Biomedia layer 10, it is ensured that most of rain after drop rainfall in the A of decanting zone Water can finally be discharged into filtering area B, and be discharged after being handled.Manifold portion of the perforated drain pipe 13 in Biomedia is in net Shape is distributed, and ensures that Biomedia fully filters rainwater.

Level is equipped with collecting pipe 14 in the gravel layer 9, and the entrance of the collecting pipe 14 is connected with one section of overflow pipe 15, institute It states overflow pipe 15 to be vertically arranged in filtering area, passes through the Biomedia layer 10, and entrance is higher than the Biomedia layer 10.The overflow pipe 15 can be used as flushing channel, when collecting pipe 14 is blocked, can with external source to collecting pipe 14 into Row rinses.The outlet of the collecting pipe 14 is across the partition wall 4 and is passed through in the C of catchment.It is equipped at intervals on the collecting pipe 14 Trepanning 16.The rainwater for entering gravel layer 9 after the processing of Biomedia layer 10 is entered by trepanning 16 in collecting pipe 14, is then discharged To catchment C.

The lower end of the catchment C well body side walls, which flushes, is provided with outlet pipe 17 at well body bottom surface.

Further, on the drainage bucket 7 overflow port 18 is also set up at flase floor 6.When the pollution that drainage bucket 7 intercepts Object is excessive, and when drainage rate is relatively slow and water level reaches overflow port 18, the rainwater in drainage bucket 7 can directly be flowed out through overflow port 18, Into decanting zone A.

Further, 10 top of the Biomedia layer is equipped with riprap 20 close to the side of overflow wall 3.The erosion control Stone riprap 20 can be used for reducing the flow velocity that the rainwater come is flowed through from overflow wall 3, and rainwater is avoided to carry out erosion to Biomedia layer 10.

Further, Biomedia is selected from litter compost, float stone, peat soil, perlite, zeolite, haydite, biological activated carbon Or it is one or more in sand.

Further, it is provided with well lid 21 on the cover board 2 above the catchment C, can be observed by the well lid 21 The inner case of well body, it is convenient that well body inside is safeguarded and handled.

Well body 1 and cover board 2 in the present embodiment can be prefabricated, and complete equipment can install and tested in factory, reduce Field erected time, installation effectiveness are high.

Embodiment 2

It is a kind of to be using the method that the enhanced Rain Garden of integration handles rainwater in embodiment 1：

When rainfall, the initial rainwater warp of the pollutants such as particulate matter, suspended matter, floating material, nitrogen, phosphorus, oil and grease is carried Flase floor 6 enters well body, and drainage bucket 7 can intercept the pollutants such as rubbish bigger in initial rainwater, leaf.In gravity Under, some big particulate matters can then be deposited in the decanting zone A of well body.

With the rising of water level in the A of decanting zone, a small amount of rainwater is entered by perforated drain pipe 13 in Biomedia layer 10, warp Gravel layer 9 is passed through after the processing of Biomedia layer 10, is emitted into catchment C through collecting pipe 14, the rainwater in the C of catchment is through outlet pipe 17 discharges.

As water level continues to rise in the A of decanting zone, when water level rises to the position at 3 top of overflow wall, rainwater then can Enter filtering area B from overflow above overflow wall 3.The bottom of baffle 8 is less than the wall top of overflow wall 3, and floating material, oil and grease are then It can be intercepted by baffle 8 in decanting zone A, rainwater ensures that floating material, oil and grease will not enter filtering area from 8 flowing underneath of baffle B.Into in the rain penetration to Biomedia of filtering area B, after the processing of Biomedia, pass through the trepanning 16 on collecting pipe 14 Into in the collecting pipe 14 being laid in gravel, it is then discharged to catchment C, is finally drained by outlet pipe 17.

With the increase of rainfall, when rainfall is more than the maximum processing capability of Biomedia layer 10, in filtering area B Water level will continue to rise.When water level rises to the top of partition wall 4, rainwater directly overflows to catchment C and drains.As filtering area B When interior rainwater reaches the top of overflow pipe 15, rainwater direct overflow in part enters collecting pipe 14 and is discharged into catchment C.

When rainfall terminates, most of rainwater of decanting zone A will continue to enter Biomedia layer 10 by perforated drain pipe 13 In drain after processing, ensure that the pollutant that drainage bucket 7 is collected will not impregnate in water, while being deposited in the particulate matter in shaft bottom not Perforated drain pipe 13 can be blocked.

11 kinds of plant is in Biomedia layer 10, the substances such as nitrogen, phosphorus in can drinking up the rain.Root system of plant can be with counterweight The pollutants such as metal are intercepted and are adsorbed, while the microorganism around root system of plant can also drop organic pollution Solution.

When the enhanced Rain Garden processing capacity of integration declines, can also be maintained.Opening flase floor 6, Pond cover board 12 and well lid 21 are set, the inner case of well body can be observed, well body inside is safeguarded and handled.

Embodiment 3

A kind of structure of road rain water processing system in the present embodiment as shown in Fig. 2, its cross-section diagram as shown in figure 3, described System includes the Storm-water sewer D on town road R, and the rainwater branch pipe E being connected with Storm-water sewer D, the end of rainwater branch pipe E is set Integrated enhanced Rain Garden 23 described in embodiment 1 is arranged in the rainy mouth of a river 22, the inlet for stom water 22.

Further, the enhanced Rain Garden 23 of the integration is designed to not according to the rainfall situation of each inlet for stom water 22 Same size and specification.

More than, the embodiment of the utility model is illustrated.But the utility model is not limited to above-mentioned implementation Mode.Within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done, should be included in Within the scope of protection of the utility model.
