Description
Technical field
The utility model relates to contaminated groundwater remediation technology, particularly relates to the air supporting well system that a kind of original position removes LNAPL in underground water.
Background technology
Along with the fast development of Chinese society economy, groundwater pollution problem becomes increasingly conspicuous, and in underground water, pollutant kind increases gradually.For light non-hydrophilic phase liquid (LNAPL), as oil, kerosene, paraxylene etc., there is hangover and rebound phenomena in traditional underground water pump-and-treat system method, when in water body, LNAPL concentration is lower, its treatment effeciency sharply declines, and processing cost increases; Conventional groundwater pollution biological renovation method, although comparatively economical, repair time is long, and the requirement of microorganism to environment is higher.
Utility model content
The purpose of this utility model is to overcome weak point of the prior art, provides the air supporting well system that a kind of original position removes LNAPL in underground water.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of original position removes the air supporting well system of LNAPL in underground water, comprise into water pit shaft, upper strata air supporting well and the LNAPL gathering system that is made up of extraction pump and LNAPL retracting device, LNAPL gathering system is connected with upper strata air supporting well by the extraction tube of extraction pump being stretched into contaminant collecting groove, water inlet pit shaft is positioned at upper strata air supporting downhole, and connect with it, air supporting well nearly liquid level place, upper strata is monolateral is provided with contaminant collecting groove.Contaminated underground water enters upper strata air supporting well by water inlet pit shaft, microporous aeration device in air supporting well produces microbubble, LNAPL is made to float up to liquid level, the extraction tube of extraction pump stretches into the contaminant collecting groove of the monolateral setting in nearly liquid level place, under the extracting effect of extraction pump, the LNAPL floating over liquid level upper strata collects to contaminant collecting groove, and delivers to LNAPL retracting device by extraction tube.
Wherein said water inlet pit shaft, it is inner that to fill what be made up of gravel, gravel, boulder and cobble be continuous grading filler from fine to coarse from top to bottom, for the suspended particulate in filtering underground, reduction turbidity.
Wherein said upper strata air supporting well, microporous aeration device is installed in bottom, for generation of microbubble.
Wherein said LNAPL gathering system comprises extraction pump and LNAPL retracting device, and described extraction pump is the adjustable water pump of frequency conversion, for pumping the LNAPL in described contaminant collecting groove to described retracting device.
The utility model achieves following technique effect compared with existing common technology:
The utility model provides a kind of original position to remove the air supporting well system of LNAPL in underground water, avoids the hangover of the underground water pump-and-treat system of pollution and rebound phenomena, saves energy consumption, reduce costs; Adopt microbubble By Bubble-floating Method, can effectively remove LNAPL in underground water, substantially increase treatment effeciency; Extraction pump adopts variable frequency control, and the LNAPL that can be applicable to flexibly under multiple groundwater velocity condition repairs; Set up LNAPL retracting device, provide advantage for LNAPL processes further with reuse; System architecture is simple, and based on peripheral doses, less demanding to surrounding enviroment, strong adaptability, has the value promoted the use of.
Accompanying drawing explanation
Fig. 1 is the air supporting well system that original position provided by the utility model removes LNAPL in underground water.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
As a kind of embodiment of the present utility model, consult Fig. 1, a kind of original position removes the air supporting well system of LNAPL in underground water, comprise into water pit shaft 1, upper strata air supporting well 4 and the LNAPL gathering system that is made up of extraction pump 7 and LNAPL retracting device 8, LNAPL gathering system is connected with upper strata air supporting well 4 by the extraction tube of extraction pump 7 being stretched into contaminant collecting groove 6.
What be made up of gravel, gravel, boulder and cobble etc. filled in further described water inlet pit shaft 1 inside is continuous grading filler (3) from fine to coarse from top to bottom.
Install microporous aeration device 5 bottom further described upper strata air supporting well 4, WIH should maintain 2 ~ 2.5m deeply.
Further described extraction pump 7 is the adjustable water pump of frequency conversion.
During work, contaminated underground water enters into water pit shaft 1 by screen casing 2, and filtering suspended impurity under the filtration of filler 3, then enters into upper strata air supporting well 4.The microporous aeration device 5 be positioned at bottom upper strata air supporting well 4 produces microbubble, and the LNAPL be blended in underground water is flotated to liquid level.Under the extracting power of extraction pump 7, the LNAPL floating over liquid level upper strata enters contaminant collecting groove 6, and is promoted in external recycling device 8 by extraction tube.This completes the whole process that original position removes LNAPL in underground water, simply effectively, treatment effeciency is high.
In sum; the utility model only removes the air supporting well system of LNAPL in a underground water embodiment to original position is illustrated; but the utility model is not limited thereto; it will be appreciated by those skilled in the art that and can change when not departing from the protection domain described in claims of the present utility model arbitrarily and revise.
