Background
Groundwater, which is an important component of water resources, is one of the main water sources for urban and industrial and agricultural water, and also is the material basis for maintaining human survival and development. However, with the continuous development of the industrialization process of the modern society and the increasingly strengthened development and utilization activities of human beings on natural resources, a large amount of pollutants (such as heavy metals, persistent organic matters and the like) enter a soil system through different ways and then enter the underground water environment through migration, diffusion and infiltration, so that the problem of underground water pollution is increasingly serious, and the human health is threatened gradually. In recent years, the pollution degree of underground water in China gradually increases, the pollution range gradually spreads from cities to the periphery and from shallow layers to deep layers, the underground water pollution situation is more and more severe, and the pollution gradually becomes a prominent environmental problem influencing the national economic development and the health of people in China.
The types of organic pollutants in underground water are more, and the content of the organic pollutants changes along with the water solubility, the pollution degree and the migration distance of the organic matters. Typical organic pollutants in the groundwater in China at present comprise benzene series, polycyclic aromatic hydrocarbon, organic chlorine, organic phosphorus, polychlorinated biphenyl, polybrominated diphenyl ether, perfluorinated compounds, triazine pesticides, pyrethroid pesticides and hormone substances in daily cosmetics. Many organic pollutants have serious influence on human health, and have three causes, namely teratogenesis, mutagenesis and carcinogenesis. In addition, different organic compounds have different hazards to the organs and systems of the human body. Such as: trichloroethylene stimulates the skin and has damage to internal organs such as lung, liver, kidney and the like; benzene stimulates the skin and eyes and has damage to the nervous system, immune function and gastrointestinal tract.
Groundwater remediation is a challenging task. From the aspect of remediation mode, groundwater pollution remediation technologies can be divided into two main categories, namely ex-situ remediation and in-situ remediation. The in-situ remediation technology has less interference on the environment of soil and underground water, does not need to pump out the underground water, reduces the exposure of pollutants, has low cost and is concerned and applied more. The existing in-situ remediation technology has the problems that various medicaments are required to be added to increase the risk of secondary pollution and the process is complicated, the photocatalytic technology can decompose various organic compounds, the medicaments are not required to be added, the photocatalytic technology is a green, efficient and secondary pollution-free advanced oxidation technology, and can be applied to in-situ remediation of underground water in principle.
CN109970258A discloses a modular groundwater remediation circulating well device, which comprises a photocatalytic reaction module unit; and the vacuum extraction unit comprises an exhaust pipe and an active carbon adsorption mechanism. A circular circulating well is excavated downwards from the ground, underground water is pretreated through a lower-layer sieve tube and is used for removing suspended matters and large granular substances in the underground water and then enters the circulating well, a photocatalytic reaction net is used for reacting under the irradiation of a visible light source to remove organic pollutants in the underground water, the treated underground water is raised under the action of negative pressure generated by a vacuum extraction unit and flows out through an upper-layer sieve tube and flows back into the stratum. The aeration unit fully aerates the underground water and is used for increasing the oxygen content of the underground water so that the subsequent photocatalytic reaction can be smoothly carried out. An underground water extraction unit can be added, underground water is extracted by a submersible pump and then is sprayed and blown off by a spray head through a water pumping pipe, volatile and semi-volatile organic pollutants finally enter an activated carbon tank through a gas pumping pipe, and the pollutants are adsorbed and removed by activated carbon in the activated carbon tank and then are discharged. However, the method needs to constantly maintain the negative pressure in the circulating well, and the energy consumption is high; the influence radius of the circulating well in the groundwater environment is limited; the groundwater is sprayed on the photocatalytic reaction net after being extracted, so that the polluted groundwater can directly flow back to the stratum through the upper-layer sieve tube without being treated.
CN109384337A discloses a remediation device and a remediation method for petroleum hydrocarbon polluted groundwater. The apparatus comprises a reactor; the ultraviolet light source is arranged in the reactor; a medicine feeding pipe; a submersible pump is used for a well. Under the action of a submersible pump for a well, the mixed solution of the underground water polluted by petroleum hydrocarbon and the additive continuously enters the inner cavity of the reactor from the water inlet; under the irradiation of an ultraviolet light source, the oxidant provided by the dosing pipe is mixed and contacted with the mixed solution of the petroleum hydrocarbon polluted underground water and the additive in the inner cavity of the reactor. The method for repairing petroleum hydrocarbon polluted underground water can improve the repairing efficiency and reduce the using amount of the oxidant.
