The invention relates to a method for reducing radioactive element strontium in underground water by carbonate mineralizing bacteria. The method comprises the following steps: firstly, screening and culturing carbonate mineralized bacteria strains to prepare a high-concentration bacteria solution; mixing the carbonate mineralizing bacteria liquid, the to-be-remediated water body and the nutrient substances in proportion, and culturing the bacteria to reduce radioactive elements in the underground water by utilizing microorganisms. The microbial mineralization bacteria are used to repair underground water; the carbonate mineralizing bacteria are high in endurance capacity and can adapt to severe environments. The method has the advantages of low carbon, environmental protection and environmental friendliness, causes no damage to the native place, can be used for large-area pollution treatment, and has a wide application prospect in the aspect of groundwater radioactive pollution remediation.
Description
Technical field [0001] The invention relates to a method for carbonate mineralization bacteria to improve the radioactive element strontium in groundwater, in particular to a method for an immobilized bacteria agent to repair radioactively contaminated groundwater. Background technique [0002] Environmental pollution is a problem caused by the development of human society, especially air pollution, water pollution and soil pollution, which will bring groundwater pollution problems, mainly caused by various harmful substances entering groundwater sources. Groundwater pollution has caused a great impact on human production and life, so it is necessary to scientifically evaluate the impact of groundwater pollution, so as to propose effective treatment measures to reduce the harm caused by groundwater pollution. The characteristics of groundwater pollution are mainly concentrated in the following aspects: It is difficult to determine, because the special location of groundwater dete...
