摘要

Bioremediation of Soil contaminated by pipeline spills in the Daquin region of China is presented in this paper. The objective of the study was to determine the nutrient ratio required for the bioremediation of soil contaminated by Daqing crude oil. Several experiments were conducted using different proportions of C:N:P:K to choose the optimum ratio of nutrients to be applied for bioremediation, C is supplied from the crude oil in the contaminated soil. The moisture content, porosity, PH and temperature of the contaminated soil were adjusted for optimum conditions. The experimental bioremediation technology was conducted in a treatment unit that was 0.5 m in length, 0.7 m in width, and 1.5 m in height. The results showed that the degradation rate of Total Petroleum Hydrocarbons (TPH) increased with increased concentrations of crude oil in the soil. At the beginning of the bioremediation experiments, the degradation rate of THP is high, but it gradually slowed over the course of the experiment. The degradation rate of TPH averaged 98% over 8 months.
