Abstract
It is used to synchronously repair the polycyclic aromatic hydrocarbons contaminated and compound formulation of heavy-metal contaminated soil the present invention relates to a kind of.The compound formulation is placed in reactor, stirring is abundant, and obtains by a certain proportion of modified oxidized zinc catalyst, activated carbon, polyacrylamide, quick lime and sulfide.The compound formulation can be widely applied to polycyclic aromatic hydrocarbons contaminated and heavy metal pollution soil and groudwater remediation, and the field such as non-water harnessing of associated contamination.
Description
Technical field
The invention belongs to technical field of environmental science, and in particular to one kind be used for synchronization process it is polycyclic aromatic hydrocarbons contaminated and a huge sum of money
Compound formulation, the preparation method and use of category pollution environment.
Background technology
Soil is the base of land plant growth, is the material base of human survival, while is also source and the remittance of pollutant.
With the development of industrial or agricultural, increasing poisonous and harmful substance enters soil, have impact on the normal ecological functions of soil.Soil
In common pollutant have inorganic pollution and organic pollution, wherein inorganic pollution is mainly the heavy metals such as lead, cadmium, mercury,
Organic pollution is Polychlorinated biphenyls and polycyclic aromatic hydrocarbon etc., and they can be present in environment for a long time, and be enriched with food chain,
Human health is damaged.
If the harmful substance contents in soil are excessive, surmount the detergent power of soil, composition of the soil will be caused, tie
Structure, function are changed, and the activity of microorganism is suppressed, and harmful substance or its catabolite gradually accumulate in soil, are led to
Cross " soil-plant-people " or " soil-water-people " to be absorbed by the body indirectly, reach the degree being detrimental to health.Soil is dirty
Dye can make crops absorb and be enriched with certain pollutant, influence plant growth and agricultural product quality, cause the underproduction to agricultural production
Bring direct huge economic losses.Pollutant in soil is it can also happen that converting and migrating, subsequently into surface water, underground
Water and atmospheric environment, influence other surrounding mediums, drinking water source polluted, finally by be orally ingested, breathe suction and
The various ways such as skin contact seriously endanger health.
Realize and polycyclic aromatic hydrocarbon and the synchronous of heavy metal ion are effectively administered, be extremely urgent.Therefore, energy is researched and developed
It is enough in synchronization process is polycyclic aromatic hydrocarbons contaminated and the compound formulation of Heavy-metal Polluted Environment, for the great application value of ecological management.
The content of the invention
The present invention effectively administers to realize to polycyclic aromatic hydrocarbon and the synchronous of heavy metal ion, creatively proposes one kind
Can realize that synchronization process is polycyclic aromatic hydrocarbons contaminated and the preparation method of the compound formulation of Heavy-metal Polluted Environment, the compound formulation by
Modified oxidized zinc catalyst, activated carbon, polyacrylamide, quick lime and sulfide are combined.Activated carbon has suction-operated,
Polycyclic aromatic hydrocarbon and heavy metal ion that can be in Enriching soil, water body；Modified oxidized zinc catalyst can be realized pair under light illumination
The degraded of polycyclic aromatic hydrocarbon；Quick lime and sulfide compounding, it is ensured that system it is stable while, heavy metal ion can be realized
Effectively remove；Polyacrylamide has flocculation, can prevent secondary dirt by the heavy metal sulfide enrichment of generation together
Dye.
It is an object of the invention to provide one kind for the polycyclic aromatic hydrocarbon in processing soil, water to be used for synchronization process polycyclic aromatic hydrocarbon
Pollution and the compound formulation of Heavy-metal Polluted Environment, improve environmental improvement efficiency.
The preparation method of compound formulation of the present invention, comprises the following steps：
(1) modified oxidized zinc catalyst, activated carbon, polyacrylamide, quick lime and sulfide are weighed according to a certain percentage,
It is placed in reactor,
(2) stirring is abundant, obtains that synchronization process is polycyclic aromatic hydrocarbons contaminated and the compound formulation of Heavy-metal Polluted Environment.
Described modified oxidized zinc catalyst is Fe2O3 doping Zinc oxide catalytic, Co-doped ZnO catalyst or phosphorus doping
The one or more of Zinc oxide catalytic.
Described sulfide is the one or more of vulcanized sodium or ammonium sulfide.
Preferably, the parts by weight of described compound formulation each component are：Modified oxidized 55~65 parts of zinc catalyst, activity
4.5~11.55 parts of 15~25 parts of charcoal, 3~5 parts of polyacrylamide, 0.5 part of quick lime and sulfide.
Present invention also offers being used for of obtaining of the preparation method, synchronization process is polycyclic aromatic hydrocarbons contaminated and heavy metal pollution
The compound formulation of environment.
Present invention also offers described compound formulation synchronization process is polycyclic aromatic hydrocarbons contaminated and Heavy-metal Polluted Environment in
Purposes.
The described polycyclic aromatic hydrocarbons contaminated and environment of heavy metal pollution is included by polycyclic aromatic hydrocarbons contaminated and heavy metal pollution soil
Earth and/or water etc..
The invention has the advantages that：
1st, propose that collection be catalyzed, precipitated, being enriched in one first, can synchronization process it is polycyclic aromatic hydrocarbons contaminated with heavy metal pollution
The compound formulation of water body, soil.
2nd, the raw material sources used in the present invention are abundant and cheap, and preparation technology is simple, is not produced in production process useless
The industrial pollution such as water, waste residue.
3rd, the product prepared using the present invention has the advantages that simply efficient, cost is cheap compared with other technologies.
4th, using synchronization process proposed by the present invention is polycyclic aromatic hydrocarbons contaminated and the compound formulation of Heavy-metal Polluted Environment, directly
, being capable of the quickly and efficiently organic pollution such as degrading polycyclic aromatic hydrocarbons using sunshine as light source.
Embodiment
Below by specific embodiment, the present invention is further illustrated.
Activated carbon, polyacrylamide, quick lime, ammonium sulfide and vulcanized sodium are purchased from An Naiji chemical companies, phosphorus doping oxidation
Zinc catalyst, Fe2O3 doping Zinc oxide catalytic, Co-doped ZnO catalyst are prepared by the following method.
The preparation method of phosphorus doping Zinc oxide catalytic：Zinc nitrate hexahydrate (2.97g, 0.01mol), ANN aluminium nitrate nonahydrate
