Aggregation of Diesel Contaminated Soil for Bioremediation

摘要: Diesel contaminated soil (DCS) contained a large amount of the hydrocarbons and salt which was dominated by soluble sodium chloride. Aggregation process made desired aggregate size distribution could speed up degradation rate since aggregated DCS had better physical characteristics than non-aggregated material. Artificial aggregation increased pores >30 μm approximately 5% reduced <1 5%, but did not change percentage between 1 30 μm. The saturated hydraulic conductivity 5×10−6 m · s−1, it to 1×10−5 s−1 after aggregation. compression index 0.0186; however, artificial aggregates with without lime were 0.031 0.028, respectively. be piled 0.2 deep aggregation; applied 0.28 when formed limiting O2 transport.
