Abstract
The present invention relates to a kind of method by changing hydraulics raising artificial swamp clean effect, including step in detail below：A, artificial swamp modeling；B, water inlet；C, bottom aeration.By above-mentioned, the method by changing hydraulics raising artificial swamp clean effect of the present invention, effectively improve artificial swamp clean effect, the method is passed through using bottom aeration, control gas-water ratio to be 6:1, control hydraulic load, reach the strongest clean effect.
Description
Technical field
The invention belongs to technical field of water pollution control, led to by change hydraulic load, aeration condition particularly to a kind of
Cross and change the method that hydraulics improve artificial swamp clean effect.
Background technology
Artificial swamp is a kind of sewage treatment ecological engineering technology that 20 century 70s grow up, by substrate,
Plant, the synergism of microorganism are widely used in the purified treatment of agricultural, industry and sanitary sewage.Artificial swamp possesses to be built
The feature that if operation cost is low, clean effect is good, Landscape benefit projects, have a good application prospect.
Hydraulic load refers to the volume of the daily sewage purifying in unit area substrate.Hydraulic load is to micro- in artificial swamp
Biotic component, biochemical reaction process, the clearance of pollutant have considerable influence.
Most of research thinks, hydraulic load is lower, and the contact with substrate for the water body is more long, and biochemical reaction is more abundant at present,
Pollutant Treatment effect is also better；But also there is research to think, when hydraulic load is less, in artificial swamp, there is slough, unfavorable
In pollutant purification, pollutants removal rate, with the increase of hydraulic load, first rises and declines afterwards, there is hydraulic load critical point.?
There are some researches show under the conditions of constructed wetland plant growth is vigorous, or even occur that hydraulic load is bigger, Pollutant Treatment effect is got over
Excellent situation.
Content of the invention
The invention mainly solves the technical problem of providing a kind of change hydraulics that pass through to improve artificial swamp decontamination effect
The method of fruit, effectively improves artificial swamp clean effect, and the method is passed through using bottom aeration, controls gas-water ratio to be 6:1, control
Hydraulic load, reaches the strongest clean effect.
For solving above-mentioned technical problem, one aspect of the present invention is：Provide one kind by changing waterpower
The method that condition improves artificial swamp clean effect, including step in detail below：
A, artificial swamp modeling, are substrate using bright stone, slag, zeolite, the volume of 3 kinds of substrate is identical, and substrate is in vertical direction
In be divided into 3 layers, lay bright stone, slag, zeolite, every thickness degree 4cm from bottom to top layer successively, substrate particle diameter is in 2-30mm models
In enclosing, set up Constructed wetland system；
B, water inlet, by adjusting effusion meter, change inflow and the flooding time of Constructed wetland system in combination, thus realizing
The regulation of hydraulic load；Pollutant COD, NH3-N、PO4 3-The hydraulic load scope that-P removes is respectively 0.31-0.33,0.33-
0.36、0.36-0.42 m3/(m2•d)；
C, bottom aeration, aeration site is in the central region of bright rock layers, bottom aeration, and gas-water ratio is 6:1, control waterpower to bear
Lotus, reaches the strongest clean effect.
In a preferred embodiment of the present invention, described artificial swamp is two-stage tandem Constructed wetland system.
In a preferred embodiment of the present invention, the aeration mode of described bottom aeration selects point type continuous aeration.
The invention has the beneficial effects as follows：The a kind of of the present invention improves artificial swamp clean effect by changing hydraulics
Method, effectively improves artificial swamp clean effect, and the method is passed through using bottom aeration, controls gas-water ratio to be 6:1, control waterpower
Load, reaches the strongest clean effect.
Specific embodiment
The enforcement it is clear that described will be clearly and completely described to the technical scheme in the embodiment of the present invention below
Example is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of not making creative work, broadly falls into the model of present invention protection
Enclose.
The embodiment of the present invention includes：
A kind of method by changing hydraulics raising artificial swamp clean effect, including step in detail below：
A, artificial swamp modeling, are substrate using bright stone, slag, zeolite, the volume of 3 kinds of substrate is identical, and substrate is in vertical direction
In be divided into 3 layers, lay bright stone, slag, zeolite, every thickness degree 4cm from bottom to top layer successively, substrate particle diameter is in 2-30mm models
In enclosing, set up Constructed wetland system；
B, water inlet, by adjusting effusion meter, change inflow and the flooding time of Constructed wetland system in combination, thus realizing
The regulation of hydraulic load；Pollutant COD, NH3-N、PO4 3-The hydraulic load scope that-P removes is respectively 0.31-0.33,0.33-
0.36、0.36-0.42 m3/(m2•d)；
C, bottom aeration, aeration site is in the central region of bright rock layers, bottom aeration, and gas-water ratio is 6:1, control waterpower to bear
Lotus, reaches the strongest clean effect.
In above-mentioned, described artificial swamp is two-stage tandem Constructed wetland system；The aeration of described bottom aeration
Mode selects point type continuous aeration.
Embodiment：
It is substrate using bright stone, slag, zeolite that experiment is studied carefully middle, and the volume of 3 kinds of substrate is identical.Substrate is divided in vertical direction
3 layers, lay skilful stone, slag, zeolite, every thickness degree 4cm from bottom to top layer successively.
The bright stone selected in experiment is taken from the construction site of engineering college of Zhengzhou University Environmental Studies Institute, after measured, dry density
1.48g/cm3, porosity 45.4%.
The slag selected in experiment comes from engineering college of Zhengzhou University drinking water boiler room, after measured, dry density U2g/cnT3,
Porosity 49.3%.
Zeolite in experiment is purchased from Zhengzhou and is afraid of double sedan-chair gimmick markets, after measured, dry density 1J7g/cnT3, porosity 42.8%.
Filter out bright stone, the slag of particle diameter 1.5-2.5cm size of particle diameter 1.2-2cm size, particle diameter 0.7-1.5cm size
