Research on On-Site Experiment of Bioremediation on Oil-Contaminated Soil by Mixed Microorganism Bacteria Agent
Mixed bacteria agent made of 5 petroleum degrading strains was added to the oil-contaminated soil of site.The content of each component in oil
the soil nitrogen
phosphorus content of residual oil and the change of dehydrogenase activity and soil microbial quantity were analyzed
in order to study remediation ability of mixed bacteria for oil-polluted soil and influence factors.The results show that: the mixed bacteria in the field tests has a good degradation effect for low
high oil-contaminated soil
and preferentially degrade alkanes
secondly aromatic hydrocarbons.The degradation rate of petroleum hydrocarbon in 60 d reaches more than 88%.In the process of degradation
bacteria degrade saturated hydrocarbons obviously;each type of bacteria for oil degradation plays a certain role.Adding nitrogen
phosphorus elements reached the right proportion has significant promoting effect on degradation of petroleum contaminated soil.
