Abstract
The invention discloses a kind of method repairing waters heavy metal pollution of soil, belong to field of Environment Protection, its method is to plant Phyllostachys congesta in waters, and the present invention uses the mode at waters plantation Phyllostachys congesta, and heavy metal carries out absorbing enrichment, the clearance rate of heavy metal can reach more than 70%, there is significant Metal uptake concentration effect, low cost, operate, easy to spread, there is significant environmental protection and social benefit.
Description
Technical field
The present invention relates to waters repair and field of Environment Protection, particularly to a kind of side repairing waters heavy metal pollution of soil
Method.
Background technology
Heavy metal pollution, generally refers to mercury in soils (Hg), cadmium (Cd), lead (Pb), nickel (Ni), zinc (Zn) etc. and exceeds standard.Study carefully
Its reason, mainly includes the discharge etc. of continuous exploitation, the waste water and dregs discharge of nonferrous metallurgy industry, the three industrial wastes etc. in mine
Deng.
Heavy metal is widely distributed in air, water body, soil, organism, and bed mud be often heavy metal storage vault and
Final Destination.When environmental change, generation is converted and discharges and pollutes by the Heavy Metals in bed mud.Heavy metal can not
It is biodegradable, but there is bioaccumulation, enter human body by soil, plant, crops, health is caused greatly danger
Danger.
And heavy metal water pollution, it is one of the most serious pollution, mainly due to industrial wastewater discharge, mining smelting
Refining exposes ore deposit and enters waters by rainwater, subsoil water etc., after water pollution, directly by the mode shadow such as drinking water, irrigation water
Ring health and environment.
In order to improve waters heavy metal pollution, existing method generally comprises two classes, and a class is to use modifying agent, the heaviest
Metal deactivator, but this method can only play provisional inhibitory action, and overlong time also can cause accumulation；Another
It is the most effective, i.e. utilizes water plant to carry out absorbing heavy metal, from water plant, then extract heavy metal, this
Method is the most thorough and effective method.The existing water plant for waters heavy metal soil remediation includes multiple very water
Plant, floatingleaved plant, submerged plant, fluitante and hygrophyte, existing report can be used for Metal uptake enrichment
Water plant, can carry out certain or a few heavy metal species to a certain extent absorbing enrichment, but effect needs into one
Step improves.
Summary of the invention
The goal of the invention of the present invention is: provide a kind of method repairing waters heavy metal pollution of soil, above-mentioned to solve
Problem.
The technical solution used in the present invention is such that a kind of method repairing waters heavy metal pollution of soil, its method
For planting Phyllostachys congesta in described waters.
Phyllostachys congesta (Phyllostachys heteroclada Oliver) is the emergent aquactic plant of grass family Phyllostachys, existing report
Its pharmaceutically acceptable, ornamental of road, also has been reported that and may be used for Water warfare, for removing TN, TP and the BOD in water, but has no it
Report for Metal uptake.
The application is using Phyllostachys congesta as the new plant repairing waters heavy metal pollution, and it is for hydrargyrum (Hg), cadmium (Cd), lead
(Pb), nickel (Ni), zinc (Zn) etc. all have preferable adsorption and enrichment effect, the clearance rate for heavy metal can reach more than 70%.
It addition, as preferred scheme: at water body mixed planting Phyllostachys congesta and Water hyacinth simultaneously.
Water hyacinth (Eichhornia crassipes (Mart.) Solms) is the grass of swimming that Pontederiaceae Water hyacinth belongs to
This plant, existing report can be as feedstuff, medicinal and ornamental plant, and whether also have been reported that it can detect in water has arsenic to deposit
, say, that arsenic can be absorbed, it is also possible to purify in water the heavy metals such as hydrargyrum, cadmium, lead, but, it is for these heavy metals
Absorbability is not good enough；Present inventor, can be carried it is demonstrated experimentally that mixed planting Phyllostachys congesta and Water hyacinth significantly by substantial amounts of
The high absorption accumulation ability to waters heavy metal, the clearance rate of Heavy Metals can reach more than 95%.
It is furthermore preferred that spread plant ash in waters, its ability absorbing heavy metal can be improved further.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: the present invention uses in waters kind
Planting the mode of Phyllostachys congesta, heavy metal carries out absorbing enrichment, and the clearance rate of heavy metal can reach more than 70%, has significantly
Metal uptake concentration effect, low cost, operate, it is easy to promote, there is significant environmental protection and social benefit.
Detailed description of the invention
The present invention is described in detail below.
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment, to the present invention
It is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to
Limit the present invention.
Embodiment 1
Choosing the waters within 10 kilometers of mining area, Leshan sichuan, the content recording wherein Heavy Metals is respectively as follows: cadmium (Cd)
21.35mg/L, lead (Pb) 10.16mg/L, hydrargyrum (Hg) 6.91mg/L, manganese (Mn) 7.37 mg/L, zinc 36.51 mg/L, this waters
Interior plantation Phyllostachys congesta, after 90d, measures content of beary metal in waters, wherein, cadmium (Cd) 5.34mg/L, lead (Pb) 2.63mg/L, hydrargyrum
(Hg) 1.36mg/L, manganese (Mn) 1.49 mg/L, zinc 9.15 mg/L, it reaches more than 70% for the clearance rate of heavy metal.
Embodiment 2
Choosing the waters within 10 kilometers of mining area, Leshan sichuan, the content recording wherein Heavy Metals is respectively as follows: cadmium (Cd)
21.35mg/L, lead (Pb) 10.16mg/L, hydrargyrum (Hg) 6.91mg/L, manganese (Mn) 7.37 mg/L, zinc 36.51 mg/L, this waters
Interior plantation Phyllostachys congesta and Water hyacinth, after 90d, measure content of beary metal in waters, wherein, cadmium (Cd) 0.65mg/L, lead (Pb)
0.31mg/L, hydrargyrum (Hg) 0.34mg/L, manganese (Mn) 0.37 mg/L, zinc 1.50 mg/L, it reaches for the clearance rate of heavy metal
More than 95%.
Comparative example
For embodiment 2, using the method only planting Water hyacinth, remaining is same as in Example 2, waters after finally mensuration processes
Content of beary metal: cadmium (Cd) 11.53mg/L, lead (Pb) 7.31mg/L, hydrargyrum (Hg) 5.07mg/L, manganese (Mn) 3.25 mg/L, zinc
20.15 mg/L, it can thus be seen that after Water hyacinth and Phyllostachys congesta mixed planting, are enriched with for the absorption of heavy metal and create expectation
Less than effect.
Embodiment 3
Choosing the waters within 10 kilometers of mining area, Leshan sichuan, the content recording wherein Heavy Metals is respectively as follows: cadmium (Cd)
21.35mg/L, lead (Pb) 10.16mg/L, hydrargyrum (Hg) 6.91mg/L, manganese (Mn) 7.37 mg/L, zinc 36.51 mg/L, this waters
Interior plantation Phyllostachys congesta and Water hyacinth, and after plantation 20d, it is sprinkled into plant ash, after plantation 90d, measure content of beary metal in waters, its
In, cadmium (Cd) 0.59mg/L, lead (Pb) 0.31mg/L, hydrargyrum (Hg) 0.21mg/L, manganese (Mn) 0.36 mg/L, zinc 1.13 mg/L,
After adding appropriate plant ash, its for heavy metal elimination effect more preferably.
