Soil samples in different depths we recollected from Tiebutie pool in Daqing, which was used to take up waste water from a petrochemical plant for about 30 years. The distribution and concentration of polycyclic aromatic hydrocarbons(PAHs) in organo-mineral aggregates were analyzed. Results show that the concentration of low molecular PAHs is the highest in all fractions, and the concentration of...
Through incubation of one kind of paddy soil with different concentration of phenanthrene, the paper discusses the change of contents and its effect on enzyme activity in the paddy soil. The result indicated that contents of phenanthrene added to soil decreased gradually with incubation day. After incubation for 56d, the content of phenanthrene with high concentration (1.6 and 3.2μg/g ) declined more,...
In this research, the cement/activated-carbon solidification/stabilization (S/S) technology was used to treat contaminated soil with 500 ppm phenol, choosing ordinary Portland cement (30% or 50% w/w of contaminated soil) and activated carbon (0%-10% w/w of contaminated soil) as binder and additive respectively. The leaching test, long-term leaching test, and pore size distribution analysis of the...
