Embodiment
The utility model is explained in detail below in conjunction with the accompanying drawings.
The two level wet land treating system in a kind of river course as shown in Figures 1 and 2, on riverbank 1 and riverbed 2, described
Riverbank 1 on one-level wetland 3 is set, two level wetland 4 is set on the riverbed 2 on the described side of one-level wetland 3, described two level is wet
Ground 4 is located at the side in riverbed 2, and described one-level wetland 3 includes two layers of filter layer, the filtrate grain in the filter layer described in each layer
Footpath is different, and particle diameter of filter medium becomes big from top to bottom, and discharge outlet is set close to the side in riverbed 2 in described one-level wetland 3；Described
Two level wetland 4 includes the backgauge unit being fixed in riverbed 2, and two level is formed between described backgauge unit, riverbed 2 and riverbank 1
The receiving space 5 of the filtrate of wetland 4, described receiving space 5 is interior to place filtrate.Above-mentioned one-level wetland 3 is used to filter rainwater, two level
Wetland 4 is used to filter river；As shown in Figure 1 based on said system, the thickness of one-level wetland 3 is 30cm, in one-level wetland 3
It is interior to add drainpipe 6, river is extracted out by water pump inside drainpipe 6 and is passed through in it.In the edge on riverbank 1, barricade 8 is set,
The filtrate being mainly used in holding one-level wetland 3 of barricade 8, the bottom of barricade 8 is discharge outlet, in order to keep filtrate in discharge outlet
Overfall 9 is arranged at upper installation screen pack, the top of barricade 8；The two filter layers of one-level wetland 3 are bottom filter layers and top filtration
Layer, bottom filter layers are coarse gravel, and top filtration layer is bird's-eye gravel；The backgauge unit of two level wetland 4 inserts for several timbers
, there is the gap for being available for river to enter in riverbed 2 and with the wooden wall 10 that the tendency in river course is formed between each timber in wooden wall 10,
Receiving space 5 in wooden wall 10 is filtrate, and filtrate uses coarse gravel, in addition, the particle size of filtrate has according to a certain section of river course
The amount of the suspension of body is determined.
The processing procedure of this system is that the current of river are divided into two-way, and river is drawn through by the first via, first, water pump
Drainpipe 6 is discharged into one-level wetland 3；Drainpipe is provided with two kinds of forms, and the first is horizontal subsurface flow wetland, drainpipe 6
Delivery port 7 is located at the inside of one-level wetland 3 close to the side of road 11, and current are flowed by filtrate to river course side, and pass through gear
The discharge outlet of the bottom of wall 8 is flowed into two level wetland 4；Second is vertical-flow wetland, and drainpipe 6 is located inside one-level wetland 3
The middle and upper part of filtrate, some delivery ports is opened up on drainpipe 6, delivery port is uniformly arranged, and water flows vertically downward from filtrate middle and upper part
To the bottom of one-level wetland 3, it is flowed into afterwards by discharge outlet in two level wetland 4；Above two form works as the filter of one-level wetland 3
Expect saturation, current are entered in two level wetland 4 from the overfall 9 at the top of barricade 8；The current entered in two level wetland 4 pass through
The filtering of filtrate, with river toward downstream flow away.Second tunnel, river enter directly into two level wetland 4 and filtered, afterwards with one
The water that level wetland 3 filters, which converges, downstream to be flowed away.
In order to beautify river course, serike, plant can play a part of protecting filtrate in filter material layer, will not be by
River washes away.
The water pump of one-level wetland 3 can judge whether to need to open according to the amount of suspension in river, when two level wetland 4
Can meet the needs of filtering, one-level wetland 3 can be stopped using；If suspension is in its amount of different time sections in river
Difference, segmentation unlatching is carried out as needed；It can also be calculated according to the displacement of one-level wetland 3 and ensure that one-level wetland 3 is held into water
Reforwarding row., can also be in drainpipe 6 in order to control the displacement of drainpipe 6 not only can be by the way of above-mentioned control water pump
Upper to increase valve to control flow, using control or Electronic control manually, control needs manually to carry out it manually its valve
It is turned on or off；Electronic control can realize automatic opening and closing, can also be real to realize that it is convenient that remote control provides
Controlled when real, when detector detection river in suspension it is exceeded, automatically turn on or control valve flow.
Furthermore a kind of power by current can be designed according to local river course river flow velocity, and that river is input into one-level is wet
Water pump in ground 3, the power of this water pump are entirely derived from river flow velocity, will save substantial amounts of resource, and being capable of continuous running.
To sum up, it can be very good to realize by the cooperation of one-level wetland 3 and two level wetland 4 and suspension in river course carried out
Filter, suspension can be reduced and ensure that river course is limpid, the river after filtering returns river course, with the remaining suspension in river course
Thing downstream wetland diffluence continues to purify.
It is emphasized that：It the above is only preferred embodiment of the present utility model, not the utility model appointed
What formal limitation, every any simple modification made according to the technical essence of the utility model to above example, etc.
With change and modification, in the range of still falling within technical solutions of the utility model.
