Drainpipe 8 is made up of two DN90 collection branch pipes and DN110 water headers.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) present invention utilizes artificial continuous filter, passes through physical chemistry and biological agent, including biological oxidation, nitrification, anti-nitre
A series of effects such as change, filtering, precipitation, oxidation and reduction, effectively handle into river rainwater non-point pollution, purify into river rainwater water
Matter, it is finally reached the purpose of river water cleaning.
(2) present invention utilizes river levee construction, and without taking ground space, artificial continuous filter has processing load height, water outlet
The advantages that water quality is good, small investment, operating cost are low, construction operation maintenance facilitates, solution Urban Rain footpath that can be more satisfactory
Pollution of area source caused by stream.
(3) present invention can temporarily store rainwater, and can effectively be removed under shorter time pollution of area source residence time
Area source pollutants.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
Describe embodiments of the present invention in detail with reference to the accompanying drawings and examples.
As shown in figure 1, eco-embankment of the present invention includes the artificial permeation's system built along bank of river, a-quadrant generation in figure
Table river levee, B area are the road along river levee, and C regions are river course.Artificial permeation's system includes connecting by water inlet pipe 1 and catch-basin
The osmotic cell connect, collection water layer 7, supporting layer 6 and filter layer 5 are disposed with osmotic cell from bottom to top, collects and is provided with water layer 7
It is connected to the drainpipe 8 in river course.Valve inspection well 3 wherein among water inlet pipe 1 through catch-basin and osmotic cell, water inlet pipe 1
Inlet valve 2 be arranged in valve inspection well 3, manhole 9 is provided with the top of osmotic cell, manhole 9 is opened in close at the top of continuous filter
River course part, if the top bank slope earthing of manhole 9 is thicker, the effect of inspection shaft manhole 9 is set to be the later stage to continuous filter filler
Layer carries out desilting.
Length size in continuous filter of the present invention is 10m × 5m × 1.8m；To ensure that water distribution is uniform, set among filter tank
Partition wall wide 100mm, continuous filter is divided into two square filter tanks of construction identical, i.e., the length size in each square filter tank is
5m×5m×1.8±0.2m.Continuous filter top reserves 0.8-1.5m spaces, and temporarily storage rainwater is can be used for when rainfall is larger,
But it is unsuitable too high at the top of filter tank, determined according to river course bank slope and anterior storage processing unit elevation.
The caliber of rainwater water inlet pipe 1 is 100mm in the present invention, is connected with cloth mill weir 4, and two square filter tanks are using straight
The hanging water distribution of angle triangle weir plate, apart from packing layer about 5-20cm so that water can evenly distribute in continuous filter from top to bottom,
Weir plate is highly preferably 15-30cm, water distributor caliber 100mm in the present invention；Rainwater after processing is discharged into after collection water layer 7 is collected
In river course.
The filler of continuous filter of the invention artificial is divided into 3 layers, and the filler of filter layer 5 is particle diameter 0.2-2.0mm quartz sands, thickness
