化学氧化剂对多环芳烃污染土壤的修复效果研究
The Remedial Effect of Oxidants on Soils Contaminated by Polycyclic Aromatic Hydrocarbons
摘要
Abstract
In this paper, the remedial effects of modified Fenton and activated Sodium per-sulfate on the soils contaminated by PAHs from coking plant and oil refinery were studied with a a simulation test. The results showed that that for the coking plant soil, the best removal rate of PAHs was 90% by the modified Fenton and 97% by the activated sodium per-sulfate respectively, while in the oil refinery soil that was 86%and 91%respectively. Activated Sodium per-sulfate was better than modified Fenton, but the optimal dosage was different when reaching the best removal efficiency. Both of oxidants were friendly environmental, which would not cause secondary pollution. The oxidants could easily remove NAP, ACY, ACE, ANT and BaP, but FLA and B[b/k]F were relatively reluctant to the chemical oxidants. For the coking plant soil, the removal of light PAHs was higher than the heavy PAHs for about 5%~39%. But the oil refinery soil showed the opposite result-the removal of heavy PAHs was higher than the light PAHs for about 3%~13%. The content of total organic matter also fell off after the reaction. Activated Sodium per-sulfate showed a more drastic decline of content than the modified Fenton with the equal dosage.关键词
