Detailed description of the invention
Below in conjunction with embodiment, this utility model is described further, but this utility model is not limited to following example.
Embodiment 1
The structure that the most self-holding prosthetic device of contaminated soil based on plant bionic and vaporizer are used in combination is as shown in Figure 3；Co-ordinative construction major part includes prosthetic device main body 4, filler renovation agent 5, permeable membrane 6, accessory 7, vaporizer body 1 and vaporizer fibrous material 8.Prosthetic device main body is the hollow pipe fitting that PVC material is made；Permeable membrane is attached to bottom hollow pipe fitting；Filler is tightly packed in hollow pipe fitting, compacting；Evaporator material combines with main body, is fixed on main body pipe fitting, and vaporizer fibrous material gos deep in renovation agent filler.
Contaminated soil based on plant bionic control oneself in situ prosthetic device transpiration rate mensuration and with the comparison of plant transpiration rates.Determining the glass fibre vaporizer based on plant bionic of the present utility model transpiration rate in solution environmental sweetening of the soil environment respectively, and contrasted with the transpiration rate of Oryza sativa L., result is as shown in table 1.
Table 1 prosthetic device of the present utility model transpiration rate in water and rice soil environment and the contrast with Oryza sativa L.
As it can be seen from table 1 in the unit interval, prosthetic device transpiration rate in solution environmental sweetening of the soil environment is obviously higher than Oryza sativa L..Additionally, due to the character of prosthetic device itself can life-time service, therefore, by natural environment and the less-restrictive of condition；Cereal crops, such as Oryza sativa L., only have the trophophase in 2-3 season and (grow from different places within 1 year, Growing season is different), each growth cycle only has the time of about 3 months, and transpiration rate only is only possible to reach higher level under specific growth stage, suitable natural environmental condition.So the use in conjunction of plant bionic reparation and vaporizer accelerates the evaporation rate of soil moisture, it is easier to equally promote soluble heavy metal and the migration of organic pollution in soil, the beneficially plant bionic prosthetic device reparation to contaminated soil.
Embodiment 2
Utilize plant bionic restorative procedure that the soil of industrial pollution is repaired.Test soil takes from certain Treatment of Industrial Park of Plating contaminated soil, and according to country's standard of soil environment quality (GB 15,618 1995), Cr, Ni of contaminated soil relatively Natural Background Values exceeds standard 28.4 times, 3.1 times respectively.Industrial pollution soil is repaired by plant bionic recovery technique on the spot that utilize this utility model co-ordinative construction, and vaporizer fibrous material is glass fibre, as shown in table 2: after 1 month, in soil, Cr reduction rate is 27%, and Ni reduction rate is 24%；After 2 months, in soil, Cr reduction rate is 41%, and Ni reduction rate is 37%.
Table 2 polluted soil phyto bionics prosthesis effect
By the data in table 2 it can be seen that plant bionic recovery technique has good repairing effect for the soil of industrial pollution.Through repairing the heavy metal Cr in after stain soil and Ni has had and reduces significantly, by the later stage continue repair the standard of soil environment quality progressively making contaminated soil reach national regulation.
