Description
Technical field
The utility model is related to technical field of sewage, more particularly to a kind of constructed wetland waste water treatment technology.
Background technology
Artificial swamp is low with investment operation and maintenance cost as a kind of sewage water treatment method, the characteristics of efficiency high, in dirt
Had a wide range of applications in water treatment procedure.Artificial swamp can be divided into surface flow artificial marshland, drowned flow artificial wet land.
Surface-flow investment operating cost is low, and construction, operation maintenance are simple, but floor space is larger, pollutant burden
Smaller with hydraulic loading rate, dirt-removing power is limited；The water surface is directly exposed in air, is easily multiplied mosquitos and flies, is produced foul smell and propagation
Germ, treatment effect is influenceed larger by difference variation.
Drowned flow artificial wet land takes full advantage of Wetland Space, has played the collaboration between system (plant, microorganism and matrix)
Effect, disposal ability is stronger；Sewage is basic below bed surface, and heat insulation effect and sanitary condition are good.But engineering-built is costly,
Landscape effect is also inferior many.
The removal of organic matter and ammonia nitrogen in Wetlands on Wastewater, is influenceed larger by available dissolved oxygen in sewage.Sewage
The too high removal that can cause nitrogen in body eutrophication, therefore sewage of middle nitrogen content is most important.
The content of the invention
Utility model is in order to overcome organic matter and the problem of ammonia nitrogen removal frank reduction, knot in existing Wastewater Treatment by Constructed Wetlands
The characteristics of closing surface-flow and horizontal subsurface flow wetland, increases in the middle of combined artificial wetland and was aerated section, increases wetland variation dirty
Dissolved oxygen content in water, improves purification efficiency.
To achieve these goals, the utility model is adopted the following technical scheme that：
A kind of combined artificial wetland for increasing Air Exposure, including surface flow artificial marshland, horizontal drowned flow artificial wet land, aeration
Cross section；Surface flow artificial marshland front end is provided with water inlet pipe, and water inlet pipe is connected with water distributor, and rear end sets downflow weir, and downflow weir is with aeration
Section is crossed to be connected；It was aerated in section by aerator, aeration aerating was carried out to treatment sewage, was aerated section and is followed by horizontal drowned flow people
Work wetland；Horizontal drowned flow artificial wet land rear end is provided with collector pipe, and collector pipe is connected with outlet pipe.
It was aerated section front end to be connected with downflow weir, rear end same level drowned flow artificial wet land water distribution area is connected, and is aerated in section
If aerator；Downflow weir is located at surface flow artificial marshland rear end, and surface flow artificial marshland was aerated into section together is connected；Horizontal drowned flow people
Work wetland front end sets water distribution area, and rear end sets gathering ground, and gathering ground bottom sets collector pipe.
Treatment sewage enters surface flow artificial marshland from water inlet pipe, and with the advance of current, the dissolved oxygen in treatment water is disappeared
Consumption, dissolved oxygen concentration reduction；Treatment water, into section was aerated, is aerated by aerator by downflow weir to treatment sewage
Oxygenation, improves the dissolved oxygen concentration in treatment sewage；Water is processed by after aeration aerating, by perforated pipe evenly into level
Drowned flow artificial wet land, with the advance of current, the dissolved oxygen in treatment water is gradually consumed, dissolved oxygen concentration reduction.After treatment
Water flowed out by the collector pipe of bottom of pond.
Therefore, the utility model has the concentration for increasing the dirty oxygen in water for the treatment of, and dissolved oxygen is formed in artificial swamp
Concentration gradient, improves wetland denitrification ability, improves the effect of purification efficiency.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model, and Fig. 2 is floor plan of the present utility model.
In figure：Water inlet pipe 1, water distributor 2, surface flow artificial marshland 3, downflow weir 4, it was aerated section 5, aerator 6, water inlet pipe
7th, water distributor 8, water distribution area 9, horizontal drowned flow artificial wet land 10, receipts pool 11, collector pipe 12, outlet pipe 13.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and detailed description：
A kind of combined artificial wetland of increase Air Exposure as shown in Figure 1, including water inlet pipe (1), water inlet pipe (1) are followed by
Water distributor (2), water inlet pipe (1) is connected with surface flow artificial marshland (3), and surface flow artificial marshland (3) front end sets water distributor (2), rear end
It is connected with downflow weir (4), downflow weir (4) is connected with section (5) front end was aerated, was aerated in section (5) and sets aerator (6), is exposed
Gas crosses section (5) rear end and sets water inlet pipe (7), and water inlet pipe (7) is connected with water distributor (8), and water distributor (8) is distributed in horizontal drowned flow artificial
In the water distribution area (9) of wetland (10) front end, horizontal drowned flow artificial wet land (10) rear end sets receipts pool (11), receives pool (11) bottom
Arrangement collector pipe (12), collector pipe (12) same to outlet pipe (13) are connected.
With reference to Fig. 1, principle of the present utility model is as follows：Treatment sewage enters surface-flow, with the advance of current, sewage
In suspension and BOD be removed, organic nitrogen ammonification, treatment sewage in dissolved oxygen concentration reduction.Treatment sewage enters aeration
Duan Hou, through the aeration aerating of aerator, increases the dissolved oxygen concentration in treatment sewage, and ammonification nitrogen carries out nitration reaction, together
When enhance treatment sewage in BOD removal, improve purification efficiency；Enter horizontal subsurface flow wetland by the sewage after aeration, with
The advance of current, the dissolved oxygen in sewage is consumed, dissolved oxygen concentration reduction occurs denitrification, and the nitrogen in water is able to
Removal.Therefore, the utility model uses combined artificial wetland, combines the spy of surface flow artificial marshland and horizontal drowned flow artificial wet land
Point, while add it was aerated section between the two, the dissolved oxygen in increased Wastewater Treatment by Constructed Wetlands in sewage disposal process,
Dissolved oxygen concentration gradient is produced in artificial swamp, the clearance of nitrogen and organic matter is improved.
