Paper Title:
Experimental Study on Bioremediation of Petroleum Contaminated Soil in Puyang Oilfield
  Abstract

According to the previous experience on remediation experiment in laboratory and field, the study on microgial ecological remediation of petroleum contaminated soil in Puyang oilfield was carried out under 3 different conditions. Here the results from remediation show that the technology of microbe cooperated with alfalfa, single microbe technology and single alfalfa technology all possess remedial effect on petroleum contaminated soil through 99-day period remediation, and the technology of microbe cooperated with alfalfa creates the best remedial mission with petroleum hydrocarbon degradation rate of 65.27%, while the rest single technologies exerts degradation rate of about 40% on petroleum hydrocarbon, Moreover, the experiment results indicate that few nutriment such as soluble salt, NO3-, Cl-,etc can infiltrate into the lower soil layer(50cm). However, the distinct increase of NH4+ in the second and third remediation area may attribute to abundance fertilizer transportation into depth soil layer due to the nitrogen fixation of alfalfa’s roots. In addition, we also find that the remediation effect can be impacted by the factors containing tempertation, water, oxygen, nutriment and mini-geo-enviroment.
