| 1 | Enhanced bioremediation of oil contaminated soil by graded modified Fenton oxidation显示文摘Graded modified Fenton's (MF) oxidation is a strategy in which H 2 O 2 is added intermittently to prevent a sharp temperature increase and undesired soil sterilization at soil circumneutral pH versus adding the same amount of H 2 O 2 continuously.The primary objective of the present study was to investigate whether a mild MF pre-oxidation such as a stepwise addition of H 2 O 2 can prevent sterilization and achieve a maximum degradation of tank oil in soil.Optimization experiments of graded MF oxidation were conducted using citric acid,oxalic acid and SOLV-X as iron chelators under different frequencies of H 2 O 2 addition.The results indicated that the activity order of iron chelates decreased as:citric acid (51%) > SOLV-X (44%) > oxalic acid (9%),and citric acid was found to be an optimized iron chelating agent of graded MF oxidation.Three-time addition of H 2 O 2 was found to be favorable and economical due to decreasing total petroleum hydrocarbon removal from three time addition (51%) to five time addition (59%).Biological experiments were conducted after graded MF oxidation of tank oil completed under optimum conditions mentioned above.After graded oxidation,substantially higher increase (31%) in microbial activity was observed with excessive H 2 O 2 (1470 mmol/L,the mol ratio of H 2 O 2:Fe 2+ was 210:1) than that of non-oxidized soil.Removal efficiency of tank oil was up to 93% after four weeks.Especially,the oil fraction (C 10 -C 40 ) became more biodagradable after graded MF oxidation than its absence.Therefore,graded MF oxidation is a mild pretreatment to achieve an effective bioremediation of oil contaminated soil. | Jinlan Xu Lei Xin Tinglin Huang Kun Chang | 2011 | Journal of Environmental Sciences2011，23，11： | 17 |
| 2 | Comparisons of the film peeling from the composite oxides of quartz sand filters using ozone, hydrogen peroxide and chlorine dioxide显示文摘To solve the problem of shortened backwashing intervals in groundwater plants, several disinfectants including ozone(O3), hydrogen peroxide(H2O2) and chlorine dioxide(Cl O2)were examined to peel off the film from the quartz sand surface in four pilot-scale columns.An optimized oxidant dosage and oxidation time were determined by batch tests.Subsequently, the optimized conditions were tested in the four pilot-scale columns. The results demonstrated that the backwashing intervals increased from 35.17 to 54.33(H2O2)and to 53.67 hr(ClO2) after the oxidation treatments, and the increase of backwashing interval after treatment by O3 was much less than for the other two treatments.Interestingly, the treatment efficiency of filters was not affected by O3 or H2O2 oxidation;but after oxidation by ClO2, the treatment efficiency was deteriorated, especially the ammonia removal(from 96.96% to 24.95%). The filter sands before and after the oxidation were characterized by scanning electron microscopy and X-ray photoelectron spectroscopy.Compared with the oxidation by O3 and H2O2, the structures on the surface of filter sands were seriously damaged after oxidation by ClO2. The chemical states of manganese on the surfaces of those treated sands were only changed by ClO2. The damage of the structures and the change of the chemical states of manganese might have a negative effect on the ammonia removal. In summary, H2O2 is a suitable agent for film peeling. | Yingming Guo Tinglin Huang Gang Wen Xin Cao | 2015 | Journal of Environmental Sciences2015，27，8： | 6 |
