Description
Technical field
The present invention relates to a kind of soil and underground water pollution control technology, and in particular to a kind of underground water home position strengthening biology
Restorative procedure.
Background technique
In-situ Bioremediation Technology of Contaminated Groundwater is the biodegradation by microorganism to Organic Chemicals In Groundwater,
Pollutant is transformed into the recovery technique of innocuous substance.Microorganism by resolution organic pollutant, provide nutrient needed for itself and
Organic pollutant is decomposed into carbon dioxide and water by energy.The reparation of underground water biology in situ can be divided into two kinds: the first is logical
The growth and breeding of indigenous microorganism in stimulation oversaturation water-bearing layer carrys out degradable organic pollutant, and it is to pass through that stimulation indigenous microorganism, which is grown,
To water-bearing layer electron injection donor (being suitable for anaerobic organism bacterium) or electron acceptor (being suitable for aerobe bacterium) and nutrients
Matter is realized.The electron donor usually injected includes lactate, the vegetable oil of emulsification or molasses etc., and electron acceptor includes sky
Gas, oxygen or oxygen release compound etc..Second is to inject external artificial culture to water-bearing layer to tame specific microorganism,
Also electron injection donor or electron acceptor, nutriment simultaneously, promote the growth and breeding of microorganism.Second method is known as underground
Water home position strengthening bioremediation technology.
Golden morning sunlight etc. " In-situ Bioremediation Technology of Contaminated Groundwater " (" urban environment and urban ecology ", 2 months 2002,
The phase of volume 15 1) dynamic circulation well In-situ Bioremediation Technology of Contaminated Groundwater is discussed in a text.The technology is laid in underground water upstream and is taken out
Well is mentioned, will come on the groundwater extraction of pollution after adding nutriment and oxygen by ground installation, be recycled under underground water
The reinjection well laid is swum, groundwater dynamic circulation is formed.After aerobic microbiological in underground water will obtain nutriment and oxygen
Growth and breeding is with degradable organic pollutant.This technical disadvantages is the underground water range for being difficult to determine that dynamic circulation well can be repaired,
Additionally needing will be handled on groundwater extraction, and energy consumption is higher, and the ground installation investment of required construction is larger.
Suthan S. Suthersan etc. is in " Remediation Engineering-Design Concepts
Second Edition " it discusses in a book to underground water and injects compressed air technique, promote original aerobic micro- life in underground water
Object growth and breeding is with degradable organic pollutant.This technical disadvantages is original aerobic microbiological limited amount, underground water in underground water
Repairing efficiency is longer, at least needs for 2 ~ 3 years.In addition, this book does not discuss how underground water injector well is laid out in the plane.
Summary of the invention
In order to solve the problems in the existing technology, the present invention provides a kind of biological prosthetic side of underground water home position strengthening
Method, the biological renovation method repair well by laying, and are successively aerated after injecting aerobe microbial inoculum in repairing well, complete underground
The reparation of water.It is repaired in well reparation radius, is realized quickly in repair by being aerated quickly to diffuse to aerobic biological bacteria
The purpose being lauched.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of underground water home position strengthening biological renovation method, which comprises the steps of:
1) it lays and repairs well；
2) the pressurization injection aerobe microbial inoculum in repairing well；
3) it successively recycles in turn and reparation well is aerated, until quality of groundwater is up to standard.
Further, the laying is repaired well and is included the following steps:
It 1a) determines and repairs radius R；
Four reparation wells 1b) are laid in place in quasi- repair, so that the regular quadrangle that side length is 2R is formed between four reparation wells,
Again in one reparation well of center setting on positive four side；
1c) arrange that other repair well successively according to the method for step 1b), so that the intersection covering of all circles is quasi- to repair place, institute
It states circle to refer to centered on repairing well, radius is the circle for repairing radius R.
Further, further include step 1d) lay monitoring well.
The determining method for repairing radius R are as follows: build one in paraprotehetic underground water place and repair well, in the reparation
2m successively lays multiple monitoring wells at equal intervals around well, toward reparation well continuous injection compressed air or after oxygen 30 ~ 90 minutes, ground
It is lauched dissolved oxygen and can rise to 2 ~ 10mg/L or more and be determined as repairing radius R with a distance from the farthest monitoring well of well from repairing.
The monitoring well of laying includes: to lay monitoring well in the points of tangency of any two circle.
The aerobe microbial inoculum need to be screened in advance, be tamed, and have good biological degradation effect to the pollutant of quasi- improvement.
Successively recycle be aerated to reparation well in turn in step 3) and refer to: arbitrarily choosing N number of reparation well is one group, is used
Air compressor or pressure gas tank are aerated in turn, and preceding a bite repairs well injecting compressed air or oxygen is aerated 30 ~ 90 points
Clock, interval 15 ~ 30 minutes, after the completion of interval, lower a bite repairs well and starts to be aerated, and N number of reparation well starts after completing a wheel
The circulation of next round.
Compared with the prior art, the advantages of the present invention are as follows:
1) the groundwater remediation well in the technical program had not only been used for aerobe microbial inoculum, but also for injecting compression air or oxygen.
Compressed air or oxygen, which quickly diffuse to aerobic bacteria agent by microbubble, repairs well reparation radius.Aerobe bacterium
Raised growth breeding degrades pollutant, has achieved the purpose that quick reparation underground water;
2) dynamic circulation well In-situ Bioremediation Technology of Contaminated Groundwater is difficult to determine the underground water that each pair of dynamic circulation well can be repaired
Range, the present invention can be apparent centered on clear groundwater remediation well, and radius is that the intersection of the circle of reparation radius covers
The underground water pollution region of required reparation.In addition dynamic circulation well In-situ Bioremediation Technology of Contaminated Groundwater needs to take out underground water
It is brought up and is handled, energy consumption is higher, and the ground installation investment of required construction is larger.This technology is without building at the surface water
Manage facility；
3) compared with simple underground water injects compressed air technique, it is good that this technology method has been injected using groundwater remediation well
Oxygen bacteria agent substantially reduces the groundwater remediation time.
Detailed description of the invention
