Guard system includes the dropper conduit 8 and compressed air hose 9 in being inserted in the white pipe 1 and the screen casing 3, and the dropper is led
Pipe 8 is spliced by multistage, and the top that the bottom of the dropper conduit 8 has angular cut 12, the angular cut 12 offers
For fixing the perforation 13 of the bottom of the compressed air hose 9, generally described perforation 13 is located at the top 5cm of the angular cut 12
Place, the upper end of the compressed air hose 9 is connected through the well head threeway 2 with air intake valve 16, the dropper conduit 8
Upper end is connected with vavuum pump, and between the top of the top of the dropper conduit 8 and the white pipe 1 movable sealing top is provided with
Lid 14, is provided with the fixed structure for fixing the movable sealing top cover 14 on the white pipe 1.
Extraction well under ground portion and conventional extraction well are basically identical, are known technology in industry, repeat no more.
The dropper conduit 8 is hollow circular conduit, and material can be UPVC, stainless steel etc., and external diameter is according in extraction well
Determining, 20mm typically at least little than extraction well internal diameter is easy to place compressed air hose 9 and possible liquid level or pressure in footpath
Probe and signal transducting wire.
It is preferred embodiment that dropper conduit 8 described in multistage is each other using the side of threaded connection in the present embodiment
Formula is spliced, as shown in Fig. 2 dropper conduit 8 is connected using screw thread 11, in addition can also be by the side such as loose joint, snap joint
Formula connects.
The dropper conduit 8 is 0.5-1m per segment length, is fluctuated less area in level of ground water 1010, is typically designed as
The segment of 0.5m；In the area that underground water fluctuation is larger, the segment of 1.0m is typically designed.
The position of the angular cut 12 of the bottom of dropper conduit 8 is needed according to the region of level of ground water 10 fluctuation situation and place
Characteristic condition comprehensively determines that the angle of the angular cut 12 is 45 ° -60 °.
Movable sealing top cover 14 is quality of rubber materials, and middle part perforate, aperture is slightly less than the external diameter of dropper conduit 8, dropper conduit 8 from
The mesopore of movable sealing top cover 14 is passed and is connected with the vavuum pump of rear end.Due to the retractility of rubber, it is possible to achieve adjustment dropper
The position in extraction well of conduit 8.After dropper conduit 8 is adjusted in place, by fixed structure, such as anchor ear 15, clamping movable sealing top
Lid 14 realizes sealing, invention describes a kind of coordinate the simple combination of anchor ear 15 realizing by rubber movable sealing top cover 14

The bottom of pipe 8, the tolerance for controlling whether to introduce air and introducing air by air intake valve 16.
By way of introducing air or compressed air to the bottom of dropper conduit 8, can be in underground water buried depth more than 10
The area operation list pump multiphase extraction system of rice.Cardinal principle is to reduce its density after air and polluted underground water mixing, can
Significantly improving for ability is extracted under to realize identical negative pressure ability.Additionally, the process of steam-water mixing is also a kind of process of stripping,
By the volatile materials stripping in polluted underground water out, the load of subsequent wastewater treatment can be reduced.The waste gas of stripping process
Qualified discharge after subsequently being processed by modes such as charcoal absorption, condensations.
During system operation, when vavuum pump negative pressure meets extracting hoisting power, it may not be necessary to tonifying Qi；When underground water buried depth
It is relatively deep, when vavuum pump negative pressure is unsatisfactory for extracting hoisting power, the tonifying Qi of air intake valve 16 can be opened, so as to realize extracting.When being
System operation a period of time, underground water produces certain drawdown, has enough soil gas to turn off air intake valve 16 when supplementing.
Now, negative pressure can be regenerated in extraction well, soil gas, underground water, free phase (if any) are by simultaneously with steam water interface
Form is extracted, so as to reach removal pollutant, the purpose of rehabilitating soil underground water.
In order to realize optimized implementation result of the invention, this application provides based on reparation purpose optimal control method,
It is specific as follows：
The placement location of dropper conduit 8 is according to place hydrogeologic condition and repairs purpose comprehensively determination.When needing back
Receive free phase when, then the angular cut 12 of dropper conduit 8 is placed on the middle part of free phase layer position, by reduce underground water drawdown with
The mode of extracting amount realizes the maximization of free phase organic efficiency.When needing to realize that the drawdown of level of ground water 10 maximizes purpose,
Then dropper conduit 8 is placed on extracting bottom.When there is no free phase, typically dropper conduit 8 is placed on into pollution most
Serious water table position, can improve remediation efficiency.
