Description
Technical field
The present invention relates to technical field of soil remediation, specifically a kind of nickel contamination soil-repairing agent.
Background technology
Soil is the valuable source of natural environmental elements for the survival of mankind and agricultural production, and it is in natural environment
Center, carries in environment about 90% pollutant from each side.At present, the annual average emission hydrargyrum in the whole world is about
1.5 ten thousand tons, 15,000,000 tons of manganese, 3,400,000 tons of copper, 5,000,000 tons of lead, 1,000,000 tons of nickel, the agricultural land soil for causing countries in the world is present
Different degrees of heavy metal pollution.
Nickel is the constituent of urase in plant body, has close association with nitrogen metabolism.Seed can be promoted to sprout, plant life
Long development, volume increase, and it is relevant with the mithridatism of plant, strengthen disease resistance of plant.Micro nickel has facilitation to plant, excessive
Inhibitory action will be produced to the growth of plant.Plant is very sensitive to nickel, when the concentration of nickel in nutritional solution is more than 1mg/L, some
Plant just occurs poisoning symptom, shows as root growth and is obstructed, plant is short and small, leaf rolling, yellow, there is speckle in severe patient
Shape necrosis, its structural performance is tissue disruption, cell induration, chlorophyll decomposition.
Nickel is element necessary to human body.It participates in the metabolism of nucleic acid and protein, and adult takes in daily from diet
The nickel of 0.3-0.5mg, main source vegetable and frumentum.Typically be not in scarce nickel phenomenon because people is very low to nickel demand.Phase
If anti-intake is excessive, canceration or other diseases can be caused.If human body Prolonged exposure is in nickel contamination (metallurgical, plating, electric welding
Deng) in environment, skin allergy can be caused, pulmonary fibrosiss, kidney and disorder of circulatory system and respiratory cancer and induced tumor are disliked
Change etc..
At present, the main artificial source of nickel includes agriculturally applying sludge and nickeliferous phosphate fertilizer in soil, industrially smelt,
The activity such as mining causes the sedimentation of nickeliferous micronic dust, contains in metal plating, oil hydrogenation, dyestuff, ceramics, the garbage of glass production
Nickel and its oxide.For the mankind, food is the main source of nickel, therefore, excessive nickel how is avoided from agricultural land soil
And irrigation water has received the extensive concern of environmental science worker into food chain.
At present, it is available for administering the main rationalization repairing method of method and biological restoration of heavy metal-polluted soil nickel contamination.Physics and chemistry
Repairing method has soil moved in improve the original (soil removal and replacement) method, the sedimentation method, elution method, electrochemical process, magnetization method.These either physically or chemically respectively have its excellent
Point, but it is usually present that treatment effeciency is not high, easily cause secondary pollution problems.
