Micro-organism eliminating method for contaminated underground water

The present invention relates to environment protecting technology. The micro-organism eliminating method for contaminated underground water includes the following steps: to prepare acclimated biological stuffing haydite layer, to pump underground water to surface, to adsorb through biological stuffing haydite tower, and to adsorb through active carbon tower. The said method can reduce petroleum organism content from 1-15 mg/L to 0.2 mg/L, reaching industrial water standard. The said method has the advantages similar to that of biological oxidation method and active carbon adsorption method and has smell covered area and short treatment period.
