Description
Technical field
The present invention relates to underwater prevention technical fields, more particularly to a kind of polluted underground water repairing and treating method.
Background technique
Underground water refers to water of the preservation in below ground rock gap, refers to that groundwater level or less is saturated aqueous in the narrow sense
Water in layer.Underground water is the important component of water resource, is agricultural irrigation, industrial and mineral and city since water is stable, water quality is good
One of the important water source in city.Certain human factors will cause quality of groundwater deterioration, if industrial wastewater is to underground direct emission, by
The surface water of pollution invades in underground reservoir, human and animal excreta or contaminated water permeates the ground because pesticide is excessively used
Deng.Pollution the result is that making containing for harmful components such as phenol, chromium, mercury, arsenic, radioactive substance, bacterium, organic matter in underground water etc.
Amount increases, and the underground water of pollution is all harmful to human health and industrial and agricultural production.Existing groundwater remediation method is very much
By the way of traditional extraction processing, need to use very more equipment in treatment process, treatment cost is high, multiple in operation
It is miscellaneous.

The movement of disconnected pollutant, and to the underground water sample detection in underground water place to be repaired, determine the pollutant kind of underground water
And concentration；
(2) pollutant kind and concentration of the underground water obtained according to step (1) is chosen bioremediation agents raw material, is put into
It stirs and sterilizes into bioreactor, inoculate strain, fermentation obtains bioremediation agents；
(3) groundwater extraction is degraded into the bioreactor, the groundwater recharge after degradation into soil,
Microbial inoculum and oxygen are mixed in the underground water during recharge, circulation carries out.
In a preferred embodiment of the present invention, water retaining device described in step (1) is cement plate, plastic plate or geotechnique
Film.
In a preferred embodiment of the present invention, underground water sample detection described in step (1) be using liquid chromatograph,
The detection mode that mass spectrograph, pH meter, transmissometer, filter plotometer, conductivity meter combine.
In a preferred embodiment of the present invention, strain described in step (2) is rhizobium, brucella, lichens bud
One of spore bacillus, Flavobacterium, pseudomonas aeruginosa, corynebacteria, bacillus subtilis are a variety of.
In a preferred embodiment of the present invention, the time of degradation described in step (3) is 4-12 days.
In a preferred embodiment of the present invention, the temperature of degradation described in step (3) is 25 ° -30 °.
In a preferred embodiment of the present invention, bioreactor described in step (3) has delivery of supplemental oxygen during operation
Gas.
The beneficial effects of the present invention are: polluted underground water repairing and treating method of the invention, input cost are low, it is only necessary to less
Rehabilitation expense, can handle on the spot, using upper simple and convenient, ambient enviroment be interfered few, pollutant can be dropped in situ
Solution is removed, and the short time just realizes excellent repairing effect, will not generate secondary pollution.
Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
A kind of polluted underground water repairing and treating method, including step are provided are as follows:
(1) water source in underground water place to be repaired is blocked with water retaining device, by the underground water in underground water place
Completely isolated with the water source of surrounding, the water retaining device can be cement plate, plastic plate, one or more of in geomembrane
In conjunction with, make water source can not recharge groundwater so that the pollutant in water source be made not enter in underground water block pollutant
It is mobile；
(2) to the underground water sample detection in underground water place to be repaired, the underground water sample detection is using liquid phase
The detection mode that chromatograph, mass spectrograph, pH meter, transmissometer, filter plotometer, conductivity meter etc. combine, the liquid chromatogram
Instrument and the mass spectrograph can measure the substances such as the organic substance contained in underground water and heavy metal, and the pH meter can determine that underground water
PH value, the transmissometer can determine that the turbidity of underground water, and filter plotometer can determine that the coloration of underground water, and conductivity meter can be really
Determine the conductivity of underground water, other instruments can also be aided with and detected, determines the pollutant kind and concentration of underground water；
(3) pollutant kind and concentration of the underground water obtained according to step (2) chooses bioremediation agents raw material, biology
The selection of renovation agent mutually resists with the pollutant in underground water carrys out selection, is put into bioreactor and stirs and sterilize, then connects
Kind strain, the strain are rhizobium, brucella, bacillus licheniformis, Flavobacterium, pseudomonas aeruginosa, rod-like stem
One of bacterium, bacillus subtilis are a variety of, and according to the total pollutant of underground water come selection, fermentation obtains biology and repairs
