Description
Technical field:
The present invention relates to a kind of chemical pollution site remediation methods, belong to environmental engineering technical field.
Background technique:
Pollution on the environment is mainly the pollution of organic matter and inorganic wastes, these substances can be long by osmosis
Phase infiltrates soil, causes adsorption by soil noxious material.The poisonous substance in chemical plant is extremely complex, different types of chemical plant feature pollution
Object is different, the waste of some discharge sulfur-bearings containing ammonia, also has containing benzene, aldehyde, ether material, chemical characteristic is different, the extent of injury
It is different.Some plot are seriously polluted, used in the case where no progress soil remediation by exploitation, give body health of people
Bring grave danger.
Currently used restorative procedure has a transposition repairing and in-situ immobilization, main mode have soil replacement and backfilling, dilution of pouring water,
In drying and processing backfill and lime and waiting, the reparation difficulty of these methods is big, the period is long, at high cost, one hectare of contaminated land,
Rehabilitation expense several hundred million members or more than ten00000000 yuan easily, of such a size capital investment, enterprise is difficult to bear.
Summary of the invention:
The purpose of the present invention is providing a kind of chemical pollution site remediation method in view of the above problems, repairing effect is good,
It is at low cost.
Above-mentioned purpose is realized by following technical scheme:
A kind of chemical pollution site remediation method, this method comprises the following steps:
(1) to chemical pollution place carry out it is smooth after be isolated；
(2) microorganism remediation is used, repairing efficiency is 6-12 months；
(3) it ploughs to the soil after microorganism remediation, it is smooth；
(4) vegetation repair is used, repairing efficiency is 12-24 months；
(5) vegetation is removed, the content of pollutant in soil after repairing is detected, step (2) are repeated if exceeded and arrive step (4),
Until contaminated ground detection is up to standard.
The chemical pollution site remediation method, it is as described in step (1) smooth laggard to the progress of chemical pollution place
The specific method of row isolation is: carrying out block divider wall to contaminated place first, the height of divider wall is not less than contaminated place
Contaminated place highest point；It builds divider wall and carries out prepartion of land later.
The chemical pollution site remediation method, microorganism remediation described in step (2) specifically make first
Microorganism renovation agent, the microorganism renovation agent include moving 5-12 parts of glue bacterium, 3-6 parts of cyanobacteria, sulfate also in parts by weight
5-13 parts of opportunistic pathogen, 2-6 parts of citric acid bacterium, 5-9 parts of pseudomonas syringae, 3-8 parts of Escherichia coli, bacillus subtilis 10-15
Part, 7-14 parts of staphylococcus, 1-3 parts of black-koji mould, 6-9 parts of bafillus natto, 5-10 parts of Thiobacillus, make microorganism and repair
After multiple agent, by the microorganism renovation agent made and broad-spectrum culture according to the ratio of mass ratio 1:1, uniformly launch to be repaired
Soil on, then sprinkle water.
The chemical pollution site remediation method, the broad-spectrum culture use brewer's wort.
The chemical pollution site remediation method, the amount of the watering are 2-3.5 kg of water/square metre soils, are spilt
The gap periods of water are 7-15 days.
The chemical pollution site remediation method, step is ploughed described in (3), including is ploughed at least twice, is ploughed
Depth is not less than 50cm.
The chemical pollution site remediation method, the vegetation repair refer to plantation willow, sunflower, India's grass,
The spacing in the rows of the willow is 150-180cm, plants sunflower in the interval of plantation willow, and the spacing in the rows of sunflower is 50-65cm,
Then intensively plantation India is careless again.
The utility model has the advantages that
The method that the present invention uses microorganism remediation and vegetation repair to combine, first using microorganism remediation to a huge sum of money in soil
Category is fixed, moves or converts, and changes their environmental chemical behavio4s in the soil, can promote poisonous and harmful substances removing toxic substances
Or toxicity is reduced, and to achieve the purpose that biological prosthetic, belong to based technique for in-situ remediation, it is at low cost, secondary pollution is easily controllable,
After microorganism remediation, then using vegetation repair recovery soil environment, repairing effect is good, at low cost.
Specific embodiment:
A kind of chemical pollution site remediation method of the invention, this method comprises the following steps:
(1) to chemical pollution place carry out it is smooth after be isolated；
(2) microorganism remediation is used, repairing efficiency is 6-12 months；
(3) it ploughs to the soil after microorganism remediation, it is smooth；
(4) vegetation repair is used, repairing efficiency is 12-24 months；
(5) vegetation is removed, the content of pollutant in soil after repairing is detected, step (2) are repeated if exceeded and arrive step (4),
Until contaminated ground detection is up to standard.
The chemical pollution site remediation method, it is as described in step (1) smooth laggard to the progress of chemical pollution place
The specific method of row isolation is: carrying out block divider wall to contaminated place first, the height of divider wall is not less than contaminated place
Contaminated place highest point；It builds divider wall and carries out prepartion of land later.
The chemical pollution site remediation method, microorganism remediation described in step (2) specifically make first
Microorganism renovation agent, the microorganism renovation agent include moving 5-12 parts of glue bacterium, 3-6 parts of cyanobacteria, sulfate also in parts by weight
5-13 parts of opportunistic pathogen, 2-6 parts of citric acid bacterium, 5-9 parts of pseudomonas syringae, 3-8 parts of Escherichia coli, bacillus subtilis 10-15
Part, 7-14 parts of staphylococcus, 1-3 parts of black-koji mould, 6-9 parts of bafillus natto, 5-10 parts of Thiobacillus, make microorganism and repair
