| Abstract: | Microbiological technique can be used to remove and transfer petroleum contaminant in soil. The microbe can degrade the petroleum-contaminated soil. The degradation products are CO2 and water, which cannot result in second pollution to environment. The main factors for affecting microbiologic degradation, including pH value, temperature, moisture, oxygen supply, nutrient, adding amount of surfactant and petroleum-contaminated degree, were analyzed in this paper. The adjusting methods for controlling the main affecting factors were discussed. |
