Specific embodiment
The utility model provides a kind of underground water pollution place pump-and-treat system and biological synthesis repair system, such as Fig. 1 and
Shown in Fig. 2, including pumped well 1, monitoring well 2 and water injection well 6, the pumped well 1 has more than 1, when setting multiple, phase
Mutually it is arranged at intervals in underground water pollution band 8, described each pumped well 1 connects sewage disposal and sets by the first waterline 3
Standby 4, the water injection well 6 also has more than 1, and underground water of the underground water pollution with 8 peripheries is arranged at intervals at when setting multiple
In inter space 9, and the sewage disposal device 4 connects nutrition and adds case 5 by the second waterline, and the nutrition adds case 5
Multiple water injection wells 6 are connected by the 3rd waterline and then underground is injected.The correspondence of underground water inter space 9 is dirty in underground water
The upstream interval setting multiple water injection wells 6 of dye band 8, downstream sets more than 1 monitoring well 2, when multiple monitoring well is set, can be with
Spaced setting, each monitoring well 2 also connects the first waterline.
The utility model is investigated by contaminated site, according to the flow direction 10 of underground water, groundwater contour 7 and ground
Lower water pollution reasonably lays pumped well 1, water injection well 6 and monitoring well 2 with 8 position.The laying of multiple pumped wells 1 is set with being spaced
It is optimal to be placed on axis of the underground water pollution with 8, and the influence factor for laying number has underground water pollution with 8 length, shadow
Radius, sewage treatment capacity are rung, is selected according to model according to specific hydrogeologic condition and efficiency highest cloth is extracted out to pollutant
Office's mode；Water injection well 6 is laid in underground water pollution with 8 upstream, and the influence factor for laying number has underground water pollution with 8 width
Degree, the radius of influence, injected water volume, to accelerate the flow velocity of underground water and to the souring of pollutant be final purpose；Monitoring well 2
Underground water pollution is laid in 8 downstream, laying the influence factor of number has underground water pollution with 8 width, the radius of influence, prison
The effect of well logging 2 is mainly long term monitoring quality of groundwater, if discovery is exceeded changing immediately as being drawn water into pumped well, prevents ground
8 migrated downstreams of lower water pollution band.Contaminated underground water in underground water pollution band 8 is extracted out first with pumped well 1, recycle the
Sewage is sent into sewage disposal device 4 by one waterline 3（Sewage disposal device 4 is existing equipment, according to the difference of pollutant,
Choose different equipment）, the water after treatment is up to standard passes through the second waterline again and the 3rd waterline enters the recharge of water injection well 6
Underground.By extraction, sewage disposal, re-injection for a period of time（The place of different hydrogeologic conditions, extract out, treatment, re-injection when
Between it is different, just be can determine that according to field condition）Afterwards, after the concentration of polluted underground water is reduced to finite concentration, through sewage disposal
Equipment 4 process it is up to standard after water case 5 is added by nutrition again, added in water defeated by the 3rd again after a certain amount of nutriment
Water pipeline enter the recharge underground of water injection well 6, now can suitably reduce the pump-out of pumped well 1, rely primarily on it is biological prosthetic over the ground
Lower water is repaired.
During groundwater remediation, ground water quality monitoring is carried out using monitoring well 2, once overproof water quality, monitoring well 2 is then
After exceeded water is extracted out as pumped well, the first waterline is imported, if not exceeded, carry out water quality long term monitoring.
The utility model lays some water injection wells 6 by 8 upstreams of underground water pollution band, in underground water pollution band 8 along ground
Lower current direction sets multiple pumped wells 2 in underground water pollution band 8, lays multiple with 8 downstream in underground water pollution and draws water and inspection
The monitoring well 2 of survey.The sewage disposal device 4 on ground, sewage are delivered to after underground water pollution is extracted out with 8 contaminated underground waters
Water injection well 2 of the underground water pollution with 8 upstreams and then re-injection underground are recycled to after treatment is up to standard.Underground water pollution band 8 to be extracted out
Underground water concentration step-down after, case 5 is added to processing what is injected air, nutriment in water up to standard and tamed by nutrition
Microorganism, finally enters the 3rd waterline re-injection underground, while reducing the pump-out of pumped well 1, relies primarily on biological prosthetic
Carry out groundwater remediation.Underground water pollution drawing water with 8 downstreams and monitoring with monitoring well 2 first carry out the prison of quality of groundwater
Survey, pump-and-treat system is carried out after discovery is exceeded and reinjects underground, stopped pumping during detection water quality reaching standard and re-start monitoring.
Above-mentioned detailed description is directed to illustrating for one of the utility model possible embodiments, and the embodiment is not
It is used to limit the scope of the claims of the present utility model, all equivalence enforcements or change without departing from carried out by the utility model all should be included
In the range of technical solutions of the utility model.
