Description
Technical field
The utility model belongs to environmental construction and protection technique field, and in particular to a kind of black smelly using the reparation of mid-term rainwater
The edge slope structure of water body.
Background technique
It is more than self-purification capacity that expressway around city development, which causes water body to be received dirty, and a large amount of lakes, river become black and odorous water.Black smelly water
Body formation the main reason for first is that dissolved oxygen largely consumes and reoxygenation deficiency leads to vicious circle, pollutant is by insufficient drop
Solution.When Organic Pollutants In Water too high levels, under the action of aerobic microbiological, organic matter, which decomposes, largely to be consumed in water
Oxygen makes water body be converted to anoxic or anaerobic state.Under anoxic and anaerobic condition, the metal ions such as iron, manganese in water body with
Sulphion in water forms the compounds such as ferrous sulfide, manganese sulfide.Suspended particle absorbing control ferrous sulfide, manganese sulfide etc., cause water
Body blackening；Organic matter corruption is decomposed, and is generated the odorants such as ammonia, hydrogen sulfide, mercaptan, thioether, organic amine and organic acid, is caused
Water body fouls.The principal element that being not difficult to analyze as a result, influences black and odorous water has: organic pollutant concentration, nutrient concentrations,
Pollute the time (time through going through after pollution is formed), hydraulics, temperature condition etc..
In disclosed patented technology, it is concentrated mainly on aerator about the research of the smelly water body treating of urban black,
Relevant publication patent is more.Aerator increases Dissolved Oxygen in Water, improves pollution by the pump disturbance water surface or to underwater aeration
Object decomposition efficiency inhibits anaerobism bacterium algae, is the common method for administering black and odorous water.But water body is aerated using pump machine and is existed
The problems such as consuming big, low efficiency and easily making odor causing substance loss.
Utility model content
In view of the above technical problems, black and odorous water is repaired using mid-term rainwater the purpose of this utility model is to provide a kind of
Edge slope structure, the utility model rationally utilizes mid-term rainwater resource, improves water body dissolved oxygen amount, improves black and odorous water.
To achieve the above object, technical solution adopted in the utility model is:
A kind of edge slope structure for repairing black and odorous water using mid-term rainwater, it includes the side slope for facing side positioned at black and odorous water,
It is characterized by: the side slope top is mid-term rainwater separated region, and it is provided with rain early-stage split-flow device, the rainwater
Mid-term rainwater is discharged on side slope face by initial Split-flow device for collecting and separating rainwater；The side slope middle is oxygenation area
Domain, and it is equipped with multistage step；The lower part of the side slope is water remediation region, and is equipped with cobblestone, wherein one
Cobblestone is divided to be located in black and odorous water.
Preferably, the side slope and the gradient of oxygenation region step are 3%.
Preferably, the quantity of the step is no less than 5 grades, the width of every grade of step is no less than 10cm.
Preferably, the cobblestone specification is 2-3cm.
The utility model has the following beneficial effects: the utility model is by collecting separation mid-term rainwater-rainwater oxygenation-reparation
Black and odorous water process, realize rainwater recycling and black and odorous water administer, this method have Rainwater Resources utilize, improve it is molten
It solves oxygen, inhibit the effects of black and odorous water.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
In figure: 1, side slope；2, rain early-stage split-flow device；3, step；4, cobblestone；5, black and odorous water.
Specific embodiment
The utility model in order to better understand does the technical solution of the utility model below with reference to embodiment and attached drawing
Further instruction (as shown in Figure 1).
A kind of edge slope structure for repairing black and odorous water using mid-term rainwater, it includes the side slope for facing side positioned at black and odorous water 5
1,1 top of side slope is mid-term rainwater separated region, and is provided with rain early-stage split-flow device 2, and the Rainwater Initial is abandoned
Stream device 2 discharge on 1 face of side slope (initial stage rain in rain early-stage split-flow device 2 for collecting and separate rainwater, by mid-term rainwater
Water flows into drainage pipeline by lower part, and mid-term rainwater flows into oxygenation region by side duct)；It is oxygenation region in the middle part of the side slope 1,
And it is equipped with multistage step 3；The lower part of the side slope 1 is water remediation region, and is equipped with cobblestone 4, wherein one
Cobblestone 4 is divided to be located in black and odorous water 5.
Preferably, the side slope 1 and the gradient of oxygenation region step 3 are 3%.
Preferably, the quantity of the step 3 is no less than 5 grades (particular number is determined according to oxygenation zone length), every grade
The width of step 3 is no less than 10cm.
Preferably, 4 specification of cobblestone is that (small dimension specific surface is relatively large to adhere to more micro- lifes to 2-3cm
Object decomposes black sordes matter).
A kind of principle and use process of edge slope structure that repairing black and odorous water using mid-term rainwater: 1, mid-term rainwater separates
Region: rain early-stage split-flow device 2 is for collecting and separating rainwater, and initial rainwater is flowed by lower part in rain early-stage split-flow device 2
Enter drainage pipeline, mid-term rainwater flows into oxygenation region by side duct.2, oxygenation region: staircase structural model make rainwater when flowing through because
Height difference is fallen, and contacts in dropping process with air and absorbs oxygen, and when bumping against with next stage step, spray is with bigger ratio table
Area absorbs oxygen in air；Behind oxygenation area, dissolved oxygen is significantly increased rainwater, subsequently enters water remediation region.3, water
Body restoring area: being made of 4 slope surface of cobblestone with black and odorous water 5, dipped 4 slope surface of part cobblestone of black and odorous water 5, is formed waterborne
Part and underwater portion, have stronger adaptability to SEA LEVEL VARIATION；When rainwater flows through above water, turbulent flow can be formed, further
Increase dissolved oxygen；When rainwater enters underwater portion, contact black and odorous water is simultaneously mixed, firstly, diluting effect is played to black and odorous water,
Reduce pollution concentration；Then water body is formed and is impacted, improve water project situation；Meanwhile dissolved oxygen is discharged, inhibit anaerobism bacterium algae raw
It is long, promote the aerobic microbiological decomposing pollutant in cobblestone slope surface, achievees the purpose that rainwater utilization and black and odorous water reparation.
It is described above be only the utility model Application Example, certainly cannot with this come limit the utility model it
Interest field, therefore equivalence changes made according to the patent scope of the utility model, still belong to the protection scope of the utility model.
