A method of environmental cleanup by means of microorganisms and method for the treatment of the bottom

摘要

A process for microbial remediation of soil polluted with a pollutant by introducing into the polluted soil a decomposing microorganism, a nutrient and/or an inducer necessary for the expression of a decomposing activity in the microorganism, wherein a coefficient of permeability of the polluted soil is controlled to be small and uniform so that the introduced substance may be uniformly distributed over a soil area to be remedied.;Also a process for treating soil which comprises a step of controlling the coefficient of permeability of the soil so that a peak at the substantially smallest coefficient of permeability may comprise the largest percentage in the distribution of coefficient of permeability.
