Bioremediation technology of polluted water body around abandoned mining areas
Polluted water bodies in abandoned mining areas may seep into groundwater or rivers,leading to pollution of nearby water sources.Therefore,this paper used bioremediation technology to study the remediation methods of polluted water bodies around aban-doned mining areas.The surrounding environment and relevant climate information of the mining area were analyzed,the distribution characteristics of pollutants in the polluted water bodies around the mining area was determined,and sample test point was arranged ac-cording to the distribution results.The biofilm method to repair the polluted water body in the sample test point was used.During the re-pair process,the microorganisms need to be cultivated and domesticated to further increase the activity of microorganisms to degrade sewage.The acclimated sludge was transferred into IC anaerobic reactor to produce oxidized biofilm,which was put into the water area of test point to produce oxidized biofilm through sludge adsorption,so as to achieve bioremediation of polluted water bodies.The experi-mental results indicate that the use of biofilm methods for remediation of polluted water bodies can effectively remove pollutants such as total petroleum hydrocarbons and polycyclic aromatic hydrocarbons,and neutralize the acidity and alkalinity of the water bodies,so that the water bodies can meet the safety standards for discharge after completion of remediation.
