Description of the invention: [Technical field to which the invention pertains] The present invention relates to a three-stage remediation method for contaminated groundwater, in particular to a flushing procedure, a oxidation procedure and a biological remediation of a contaminated groundwater in sequence A three-stage remediation process for contaminated groundwater that reduces the concentration of pollutants in one of the contaminated groundwater. [Prior Art] In recent years, due to the rapid development of industry, the problem of groundwater pollution has become increasingly serious, and it has gradually affected human life. Sites contaminated with dense non-aqueous phase liquids (hereinafter referred to as DNAPL), such as groundwater contaminated with gas solvents, have been found to highlight the seriousness of DNAPL contamination of groundwater. And the urgency of remediation. Therefore, countries are also actively studying the development of treatment technologies for contaminated groundwater sources. The conventional method of remediation of contaminated groundwater is to remediate a contaminated groundwater by a pump and treat method, which extracts _ contaminated groundwater from a pumping well and extracts it by other methods. Contaminated groundwater is purified. Then, the treated contaminated groundwater can be re-injected into a groundwater body through a re-injection well to reduce the pollution level of the contaminated groundwater. Another conventional method for remediating contaminated groundwater is to rectify the contaminated groundwater by an air sparging method. The main principle is to inject a gas or an oxygen into the groundwater body by using a pressure and generate a a bubble that is used to dissolve the contaminant in the contaminated groundwater, C:\Linda\PK Pat\PK975i doc 0δ/12/08/03:ΐ2 —5 — 200825029 and rises to an unsaturated soil layer with the bubble Area. In general, the method of volatility has one of the most volatile organic pollutants in the treatment of the county. In general, the following shortcomings of the above-mentioned system are affected by the pollution of the groundwater. For example: the extraction method Z method, there are 2 extractions, so that The maintenance cost of mechanical equipment and f = cause the cost of sewage treatment to be too high. Furthermore, it is not possible to move 2 effectively or to decompose the bottom located in the groundwater body ==_ time course. Based on the above reasons, a three-stage remediation method for polluting groundwater with a fork is described. In view of the above, the present invention improves the above-mentioned disadvantages of the surfactant-liquid-to-contaminated groundwater in a private order to initially remove the contaminated groundwater nine plus: the oxygen butterfly containing the surfactant component: : In the groundwater, the process is carried out by the oxidation of the pollutants; finally, the contaminated groundwater / Ding = material remediation procedure is used to degrade the pollutant. Therefore, the present invention can effectively improve the oxidation efficiency and the efficiency of remediation and reduce the cost of remediation and the time course of remediation. [Inventive content] The main purpose of the present invention is to provide a third-order method for contaminated groundwater, which is sequentially The treatment of a contaminated groundwater by a private sequence, an oxidation process and a "bioremediation process to reduce the pollution degree of the contaminated groundwater" makes the invention have the effects of improving oxidation efficiency, remediation efficiency and reducing the time course of remediation. C: \Linda\PK Pat\PK975i doc 06/12/08/03:12 P« —6 — 200825029 According to this I, the three-stage remediation method for dyeing groundwater contains: · Using the right-field $1 interface One of the active agents is a contaminated underground 2 row: a flushing procedure; an oxidation process is performed using an oxygen-containing and a groundwater containing the surfactant component; and a biological remediation procedure is performed on the contaminated subsurface to remove the Dyed matter in contaminated groundwater. . BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features, and advantages of the present invention will become more <RTIgt; The first step S1 of the three-stage remediation method of the contaminated groundwater in the present embodiment is to perform a flushing process on a contaminated groundwater using a liquid containing one of the surfactants. More specifically, the flushing process is to set at least the injection well (not shown) above the contaminated groundwater and set at least the extraction well downstream of the contaminated groundwater. Depositing a liquid containing the surfactant into the contaminated groundwater from the injection well, and increasing the solubility of one of the contaminated groundwater by the solubilization effect of the surfactant, and then pushing the liquid through the injected liquid The pollutant is discharged to the well = 're-extracted to the ground through the extraction well, thus reducing the concentration of pollutants in the contaminated groundwater. The liquid system may be selected as a ground water, a tap water or other uncontaminated liquid, and the liquid in this embodiment is preferably selected as the ground water. The contaminant is selected as a heavy non-aqueous phase solution [to TM DNAPL] contaminant 'such as - containing chlorine solution ^ C: \Linda\PK Pat\PK975i doc —7 — 56/12/08/03 :12 P« 200825029 Such as trichloroethylene (TCE) or tetrachloroethylene (perchl (10) ethylene, hereinafter referred to as pCE) and other pollutants. Referring to FIG. 1, since the surfactant is a polymer having a hydrophilic group and a hydrophobic group, the liquid containing the surfactant When the flushing process is performed on the contaminated groundwater contaminated with dnapl, the hydrophobic group of the surfactant may form an organic phase to increase the solubility of the organic pollutant, and then combine with the recorded body via the hydrophilic group. The organic > dyeable material was rinsed off via the liquid. The surfactant is selected from a nonionic surfactant or a biodegradable surfactant. Since the nonionic surfactant is less toxic, the biodegradable surfactant can be biodegraded. The invention can avoid secondary pollution to the environment. The surfactant is converted to -SIMPLE GR£en^, or Tri8〇 or a Triton ,·, but is not limited to the Tween 80 or Triton X-100 'and is preferably selected as The SG. Referring to FIG. 1 again, the present invention can select the (4) _ miscellaneous underground money line containing the interface agent before the liquidation process of the contaminated groundwater by the liquid containing the surfactant. The concentration of the contaminants of the contaminated wood ground water towel is initially reduced by the liquid containing no surfactant. The punching process injects a liquid not containing the surfactant into the contaminated groundwater from the injection well, and pushes the pollutant in the contaminated groundwater to the bottom of the extraction well through a liquid not containing the surfactant. The contaminant concentration of the contaminated ground water towel can be reduced by extracting the pollutants to the surface through the miscellaneous wells; C:\Linda\PK Pat\PK975^ doc
