Specific embodiment
Below in conjunction with specific embodiments, explanation is further described to the present invention.It should be understood that following embodiment is with this
Implemented premised on the method for disclosure of the invention, but protection scope of the present invention is not limited to following embodiments.
As shown in Figure 1, the load medicine plate 1 of a kind of processing contaminated soil and underground water, described to set load medicine plate, when setting, insert
Trigger buries rate as 6m/min；Perpendicularity deviation should be not more than ± 1.5%；It cuts more than upper soll layer exposed when carrying medicine plate
Length should be greater than 100mm.The load medicine plate 4.0~5.5mm of thickness, width 100mm, tensile strength are not less than 2.0kN/10cm,
Longitudinal flowing water measuring is not less than 50cm3/ s, bending performance are 180 ° of doubling and not broken do not remove.The load medicine plate outer layer is filtering
Film, material are polypropylene cottons, can be blocked in suspended matter, helminth etc outer.It is PVC material plastics branch inside the load medicine plate
Support, cross-sectional configuration is ' several ' font.' several ' font " one " lateral part is uniformly filled in every 10mm × 20mm size
Compound (HRC) is put in oxygen evolution compound (ORC) or hydrogen release.Filling ORC or HRC longitudinal gap is 10~20mm.Carrying medicine plate is
Guarantee this method economy, effective, feasible best compositing factor, and medicament 2 (ORC or HRC) is then to realize soil and groundwater
Middle pollutant is able to the key removed.
Place after the resettlement of certain gas station of example 1, underground water are total petroleum hydrocarbon pollution.Place gross area 2600m2, ground
Being lauched Polluted area area is about 402m2, about 680m measures in pollution side3.Major pollutants: total petroleum hydrocarbon (TPH), 1021 μ g/ of concentration
L。
Implementation steps: due to this area's soil category sand loam soil, load medicine plate of the present invention can be used, medicament selects ORC
Type.Through laboratory lab scale, 8 pieces of load medicine plates need to be laid, lay depth 3m.
Further: according to mark position is set, carrying out board-plugging device positioning.
Further: installation shoe, it is heavy set casing, booting sets to designed elevation, promotes casing.
Further: cutting and carry medicine plate, so that exposed parts are 100mm.
Further: checking that verticality 1%, goes to and sets next load medicine plate.
Further: TPH concentration in the primary measurement underground water of sampling in every 30 days, respectively 782 μ g/L, 631 μ g/L, 423 μ
G/L, terminating below reparation 600 μ g/L of target value.Fig. 3 is shown in concentration variation.
If first 30 days sampled results prediction, ORC carries medicine plate treatment effect and processing effect is not achieved within the estimated duration
Fruit can suitably add and carry medicine plate distribution.
Certain the retired place of cleaning agent manufactory of example 2, place are chlorohydrocarbon pollutions.Place gross area 7000m2, dirty
Measure about 1256m in dye side3.Major pollutants: trichloro ethylene, methylene chloride, tetrachloro-ethylene.The specific initial concentration number of 1#~4# point
According to being shown in Table 1.Concentration variation refers to Fig. 4, Fig. 5 and Fig. 6.
1 1# of table~4# point pollutant initial concentration (unit: μ g/L)
| Repair target value | 1# point | 2# point | 3# point | 4# point | |
| Trichloro ethylene | 200 | 4356 | 3987 | 4023 | 4121 |
| Methylene chloride | 200 | 2541 | 2774 | 2802 | 2793 |
| Tetrachloro-ethylene | 200 | 9342 | 8709 | 8900 | 8891 |
Implementation steps: the place infiltration coefficient is larger, and pollutant is chlorohydrocarbon, and HRC type can be selected and carry medicine plate, amount to cloth
If 10 blocks of plates.
Further: according to mark position is set, carrying out board-plugging device positioning.
Further: installation shoe, it is heavy set casing, booting sets to designed elevation, promotes casing.
Further: cutting and carry medicine plate, so that exposed parts are 120mm.
Further: checking that verticality 1.1%, goes to and sets next load medicine plate.
Further: every the concentration of the target contaminant of 4 point of monitoring in 30 days.Concentration after each point 3 months
Data are as shown in table 2 below, are below and repair target value 0.2mg/L.
Concentration (unit: μ g/L) after 2 1# of table~4# point pollutant 3 months
| Repair target value | 1# point | 2# point | 3# point | 4# point | |
| Trichloro ethylene | 200 | 67 | 73 | 77 | 52 |
| Methylene chloride | 200 | 109 | 112 | 152 | 133 |
