Description
Technical field
The utility model belongs to groundwater remediation industry, is specifically related to a kind of underground water heavy metal and organism showering device.
Background technology
Along with the development of human industry society, many industrial pollution discharges, in the surrounding medium such as water body, soil, enter groundwater environment by osmosis and groundwater recharge, thus cause groundwater pollution.According to pollutant type, groundwater pollution can be divided into Organic pollutants and inorganic heavy metal to pollute, and due to the difference of organism and heavy metal physico-chemical property, the recovery technique of Organic Contamination of Groundwater and heavy metal contamination also exists bigger difference.
Investigator has carried out more underground water recovery technique both at home and abroad at present, and multiple technologies are used for groundwater remediation engineering practice.Groundwater remediation technology can be divided into in-situ immobilization and showering according to reparation position, and the type according to restorative procedure can be divided into employed physico-chemical techniques and biotechnology etc.
Underground water dystopy chemical oxidation techniques is a kind of comparatively ripe groundwater remediation technology, and this technology for domestic groundwater remediation engineering, and achieves good effect.For except containing organism, underground water simultaneously also containing heavy metal contaminants, traditional restorative procedure mainly comprises: the technology such as permeable reactive wall, microorganism remediation, chemical oxidation and the reparation of electrochemical in-situ power, wherein permeable reactive wall, microorganism remediation, electrochemical in-situ power recovery technique are all that based technique for in-situ remediation etc. all exists the problems such as repairing efficiency length, Zhou Bengao.Organic Contamination of Groundwater thing recovery technique combines with heavy metal recovery technique by this technology, efficiently can remove pollutent.
Utility model content
Utility model object: the purpose of this utility model is to solve deficiency of the prior art, there is provided one can repair underground water heavy metal and organism simultaneously, there is good repairing effect, repairing and treating pollution type is comparatively wide, the underground water heavy metal that remediation efficiency is high and organism showering device.
Technical scheme: a kind of underground water heavy metal described in the utility model and organism showering device, comprise the preliminary sedimentation tank, oxidation pond, settling tank, secondary sedimentation basins and the PH equalizing tank that sequentially pass through pipeline and connect, the water pump that draws water, under meter and valve is also provided with between described preliminary sedimentation tank and oxidation pond, described PH equalizing tank end end is also provided with water filling water pump, described oxidation pond top is provided with dosing thief hole, described settling tank top is provided with dosing tower, be added with oxygenant in described oxidation pond, in described settling tank and secondary sedimentation basins, be all added with phosphatic rock.
As optimization, between described oxidation pond and settling tank, between settling tank and secondary sedimentation basins, PH equalizing tank end end is respectively equipped with valve.
As optimization, described oxygenant is persulphate or Fenton reagent.
As optimization, the underground water pH value scope after described PH equalizing tank regulates is 6 ~ 7.
As optimization, described underground water is through drinking-water pipe suction and discharged by water injection pipe, forms a circulating line loop.
Beneficial effect: the utility model, by adopting chemical oxidation and flocculation sediment associated treatment organism and heavy metal, can be saved duration and construction cost, have good benefit.Manageable pollutant type is comparatively wide, and repairing and treating effect is better.Therefore the underground water that the complicated concentration of pollutant type is higher is specially adapted to, as sudden groundwater pollution etc.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
