Description
Technical field
The invention belongs to ecological engineering and ecological regulation and control technical field, be specifically related to one and comment
The apparatus and method of valency plant purification ability.
Background technology
Air quality deteriorates, and haze weather occurs having a strong impact in each big and medium-sized cities of China again and again
The life that people are daily.Haze is a kind of diastrous weather, to highway, railway, aviation, boat
Fortune, electric power system, crop growth etc. all produce material impact.Mist, haze can cause air matter
Amount declines, and influence ecological environment brings bigger harm to health.When mist, haze weather,
Often with antibacterial and virus in air, it is easily caused infectious disease diffusion and multiple disease occurs.
City Air Contamination thing is difficult to diffusion, has increased the weight of sulfur dioxide, carbon monoxide, nitrogen oxides
Deng the toxicity of material, it is detrimental to health.When meeting mist, haze weather winter, if meeting air pollution
Seriously being likely to be formed the poison mists such as flue dust (mist) or black smog, the life of serious threat people is with strong
Health.Owing to mankind's activity causes pollutant in air to increase, China industrial occupancy and downtown area
Deng some areas mist, the occurrence frequency of haze and intensity in increasing trend.
In the last few years, environmental administration actively advocated and uses the method for green ecological to control to carry out air
Reason, purifies air by plant.But, green plants is big to the practical capacity of air cleaning
Little neither one the most all the time quantifies.People can only pass through zones of different (with or without green vegetation)
Air index determines that vegetation strictly has purification to haze air.Here, it is proposed that
This set experimental provision and method can to fill this part blank, by accurately controlling the life of plant
Elongate member, is tested out plant to air-filtering ability size, and is quantified by experimental data.
Carrying out Research of Environmental Sciences when, it is often necessary to some accurate index sections to be provided
Learn foundation.Time as tested different forest farm to the detergent power of air, it would be desirable to obtain one
Data judge that each forest farm purifies ability of air size accurately.Before this we can because
Lack each item data and the judgement of a science can not be made.The disclosedest technology does not has
Have and make a set of equipment specifically to quantify plant adsorbing by accurately controlling plant growing
Technology.
Recently, in terms of test vegetation absorbability, present inventors have proposed this new device,
Accurately controlled vegetation growth state by experimental box, utilize the adsorption of plant to purify sky
Gas, utilize the detection number of degrees of instrument, quantify the adsorption of vegetation.This experimental provision,
Not only it is able to verify that vegetation adsorbs haze ability, moreover it is possible to accurately measure plant pair under varying environment
In air, particle, sulfur dioxide, the size of nitrogen oxide absorbent ability, and plant are full
And adsorptive value, small particle decrement in air, sulfur dioxide in air is adsorbed by vegetation
The relevant experimental data such as speed.
Summary of the invention
The weak point existed for this area, the purpose of the present invention is to propose to a kind of by controlling
The growth conditions assessment plant device to gray haze Air purification.
It is another object of the present invention to propose by controlling growth conditions assessment plant to gray haze sky
The method of gas purification.
For realizing the technical scheme of above-mentioned purpose of the present invention it is:
It is a kind of by controlling the growth conditions assessment plant device to gray haze Air purification,
Described device includes that the proof box of 4 meters × 4 meters × 4 meters, experiment tank wall use transparent material
It is made, and ensures that experimental box will not deform at certain temperature difference, draught head.Will be real
It is placed at tryoff in an environment that can control intensity of illumination, light irradiation time and temperature constant.
Light irradiation apparatus, Full-automatic temperature humidity controller are set in proof box；Air is set in proof box
Suspended particle density measuring instrument, air carbon dioxide concentration measurement instrument, temperature testing equipment and
Intensity of illumination follows the tracks of equipment.
Use instrument, the temperature within Control experiment case and humidity.0.3 it is disposed with in proof box
The soil of meter Hou Du, and isolate 0.5 meter of spacing cultivated plant, it is ensured that sufficient light supply and water
Supply makes vegetation normal growth.
Wherein, described illumination methods is daylight and LED combination.
Preferably, described proof box has four, is respectively arranged with A, B, C, D in proof box
Four kinds of vegetation: A group shrub adds arbor；B group shrub；C group arbor；D group matched group, no
Planting plants.
Wherein, the planting distance planted in described proof box is 0.5 meter.Set in described proof box
It is equipped with CO2It is passed through pipeline；The gradient of soil is 0.03%, and the type of soil is sandy soil.
A kind of by controlling the growth conditions assessment plant method to gray haze Air purification, adopt
The device proposed by the present invention, is passed through the air gathered in the serious district of air pollution in experimental box
Sample (is collected in PM2.5 more than 250 areas), and particulate matter index is pm2.5, pm1 or pm0.5
Air (having measured the particulate matter index in air), use single argument mode test,
Through 6 hours, observe the change of each index in air, thus reach to study can control strip
The vegetation treatment effect to particle small in air under part.
Wherein, CO in proof box2Content is 0.03%, and temperature is 20 ± 3 DEG C, and humidity is 35%,
Intensity of illumination is 30,000 luxs.
Wherein, by the change of particle numerical value small in experiment with measuring case, unit plane is determined
Long-pending vegetation purifies the ability of air.
The beneficial effects of the present invention is:
The experimental provision that the present invention proposes can provide for the research that air cleaning is relevant with method
Default data.During the device of present invention proposition is tested, by univariate reality
Proved recipe method is tested, and can measure different tree species under the conditions of illumination, temperature, humidity etc. respectively
Size to Air purification, and corresponding curve chart can be drawn, set up corresponding mould
Type, by the factors such as input seeds, temperature, illumination, the directly air to different greenery patchess, forest farm
Detergent power is predicted.
