Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in figure 1, a kind of shoal formula riverway water quality purification system, including center main stem area 5 and positioned at river course bank Ecological revetment 7;It is hydrophilic heavy that water distribution area 1, shoal are sequentially set between the ecological revetment 7 and center main stem area 5 successively Shallow lake area 2 and overflow drop weir 3;The water distribution area 1 is bordered on ecological revetment 7, the overflow drop weir 3 and center main stem area 5 Border on;The interior edge bank line direction of water distribution area 1 is disposed with perforated pipe, and being piled up above perforated pipe has cobblestone;The shoal The bottom of hydrophilic settling zone 2 is cobblestone with paving material is filled out;
Wherein, circulation immersible pump 4 and submerged plant 6 are provided with center main stem area 5;The circulation immersible pump 4 passes through The pipeline 8 of riverbank bottom laying is connected with the perforated pipe of water distribution area 1;Between the circulation immersible pump 4 and pipeline 8 by hard tube or Flexible pipe installation connection, benefit is not influence the landscape and flood passage in center main stem area 5;The flow of the circulation immersible pump 4 is according to shallow The hydrophilic surface loading 0.5m of settling zone 2 in beach3/(m2D) design;Described submerged plant can be black algae, waterweed, eel grass, Potamogeton malaianus etc..
In the present embodiment, ecological revetment 7 is after bed mud desilting is carried out to riverbed, and the revetment modification of vertical hard is turned into Inclined ecological revetment 7, be advantageous to the improvement of water quality and the recovery of environment;Cobblestone above the middle punch pipe of water distribution area 1 plays The effect of energy dissipating during water distribution, while increase the landscape in river course;The hydrophilic settling zone 2 in shoal can be according to actual river width along the river Road longitudinal centre line is arranged symmetrically, can also single-sided arrangement, the water outlet of the hydrophilic settling zone 2 in shoal, can using weir flow drop design To be effectively increased the dissolved oxygen in water, the height on overflow drop weir 3 ensures the depth of water certain in the hydrophilic settling zone 2 in shoal, After quality recovery in river course, the water level in center main stem area 5 can be lifted, the water level in settling zone 2 hydrophilic with shoal flushes, Build more preferable River Landscape.
Using when, the river in center main stem area 5 is promoted into water distribution area 1 with circulation immersible pump 4, and to flow into shoal again hydrophilic Settling zone 2, the hydrophilic settling zone 2 in shoal are precipitated using the principle of shallow layer precipitating to the undissolved bulky grain thing in river, The cobblestone of the hydrophilic bottom of settling zone 2 in shoal can grow moss under sufficient sunlight simultaneously, increase the retention to particulate matter and make With then the water of the hydrophilic settling zone 2 in shoal enters center main stem area through the overflow drop water outlet of weir 3 again, can increase river Dissolved oxygen, and realize river course running water circulation.For there is a river course of more external source pollution, during application, it should also combine source and cut dirt Engineering measure, the pollutant from source reduction river course.
The hydrophilic settling zone 2 in shoal described in the present embodiment can include the hydrophilic settling zone A sections 21 in shoal and shoal is hydrophilic heavy Shallow lake area B sections 22;The hydrophilic depth of water 200mm~300mm of settling zone A sections 21 in shoal, bottom fill out paving material be particle diameter 20mm~ 40mm cobblestone;Depth of water 500mm~600mm of the hydrophilic settling zone B sections 22 in shoal, it is particle diameter 50mm that paving material is filled out in bottom ~70mm cobblestone.The hydrophilic settling zone 2 in shoal uses different depth designs, be advantageous to same center main stem area 5 build it is rich Rich micropopulation, increase the diversity of river channel ecology system.
The width ratio of the hydrophilic settling zone B sections 22 of the hydrophilic settling zone A sections 21 in shoal described in the present embodiment and shoal can be with For 2:1.
The stainless steel floral tube that perforated pipe in water distribution area 1 described in the present embodiment is a diameter of 200mm.This perforated pipe Its hardness and diameter is set effectively to meet the water distribution demand of water distribution area 1.
The particle diameter for the cobblestone piled up above perforated pipe in water distribution area 1 described in the present embodiment is 100mm~200mm. Energy dissipating covering can be carried out in water distribution by setting the cobblestone of this footpath grain.
Immersible pump 4 is circulated described in the present embodiment several is evenly arranged with identical spacing along the longitudinal direction of center river course area 5, And it is connected respectively by pipeline with the perforated pipe in water distribution area 1;Further, the spacing of the adjacent circulation immersible pump 4 is 40m~50m.The benefit so designed is that the water that can effectively enter in center main stem area 5 is purified, and is avoided because river course The long purification for influenceing water quality of length.
Paving material is filled out in the bottom of the hydrophilic settling zone 2 in shoal described in the present embodiment also includes zeolite and nano-titanium photocatalysis Agent.When poor or when deteriorating suddenly in water quality, filled out in the bottom of the hydrophilic settling zone 2 in shoal in paving material and add zeolite and nanometer Titanium photochemical catalyst, dissolved contaminants in river are adsorbed using the porosity characteristic of zeolite, and under shallow-layer illumination effect, profit Photochemical reaction is carried out with nano-titanium photochemical catalyst, improves river rate of self-purification;When the hydrophilic accumulation of pollutants of settling zone 2 in shoal compared with When more, stop circulation immersible pump 4, the bottom filling of the hydrophilic settling zone in shoal 2 turn over and washes or changes.
Also being launched in the area of center main stem described in the present embodiment 5 has zoobenthos.The water quality in river course center main stem area 5 Eliminate it is black it is smelly after, can launch zoobenthos and with the submerged plant in center main stem area 5, the hydrophilic goose ovum of settling zone 2 in shoal Moss grown on stone etc. can build rich and varied river channel ecology system.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
Part is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.
