“…Integrating advanced oxidation with bioremediation is a means to increase the biodegradability and water solubility of recalcitrant organic compounds, such as humics in natural waters, PAHs and organics in landfill leachate (Brame et al, 2013;Goi et al, 2006;Jung and Choi, 2003;Jung et al, 2005;Keen et al, 2012;Li et al, 2012;Rittmann et al, 2002;Wu et al, 2004), thus allowing microorganisms to mineralise the residuals.…”

The molecular complexity and the low solubility of petroleum hydrocarbon residuals in weathered soil hinder bioremediation as a clean-up strategy. Pretreatment with advanced oxidation, such as with ozone gas (O 3 ), is a means to transform recalcitrant organics to more biodegradable forms. The efficacy of gas-phase ozone for enhancing the biodegradability of heavy residual petroleum hydrocarbons in weathered soil was tested. Ozonating soil containing ∼1% (w/w) residual petroleum hydrocarbons with a dose of 6 kg ozone/kg initial total petroleum hydrocarbons (TPHs) achieved nearly 50% TPH reduction, simultaneous with a >20-fold increase in soluble chemical oxygen demand, but with a ≤12% loss of total organic carbon. TPH molecules were converted to partly oxidised products, ten of which were identified as n-monocarboxylic acids, which were readily biodegraded, and ozonation resulted in a fourfold increase in 5-d biochemical oxygen demand (BOD 5 ). BOD 5 results after ozonation were the same with or without a microbial seed, which suggests that bioaugmentation is likely not necessary after ozonation. Deoxyribonucleic acid sequencing over the time course of the BOD 5 tests showed increased diversity and changes in predominant genera, both of which underscore that ozonation made the heavy hydrocarbons readily biodegradable for soil bacteria.

“…São vários os trabalhos que aplicam processos oxidativos na descontaminação de solos (MacKinnon & Thomson, 2002;Goi et al, 2006;Palmroth et al, 2006;Waldemer et al, 2007;Lee, 2008). Diversos são os motivos para que a remediação de solo por hidrocarbonetos de petróleo seja objeto de intensos estudos, e alguns deles podem ser citados.…”

“…Selecting an appropriate medium to absorb the microwave energy to integrate microwave treatment technology has been developed as an effective waste treatment method. This method has been applied for disinfecting soil (Mavrogianopoulos et al 2000), immobilizing heavy metals in contaminated soil including chromium (Tai and Jou 1999) and lead (Jou 2006) and remediating polychlorinated biphenyls contaminated sites (Goi et al 2006). The microwave radiation may also combine with the adsorption capacity of granular activated carbon or zero-valent iron for treating pentachlorophenol (Jou 2008;Jou and Wu 2008) and enhancing the efficiency of titanium dioxide photocatalyst ) to save energy consumption and treatment efficiency (Liu et al 2004).…”

Organic compounds such as chlorobenzene cannot be effectively decomposed with currently available biological and chemical treatment methods. Preliminary studies show that nano-scale zero-valent iron particles irradiated by microwave is effective in decomposing chemically refractive organic compounds such as chlorobenzene. In this study, microwave is applied to enhance chlorobenzene removal using micron-scale iron particles and nano-scale zero-valent iron particles suspended in the chlorobenzene solution as the dielectric media. The results show that better chlorobenzene removal can be achieved when the chlorobenzene solution is irradiated with 250 W microwave for 150 s than without microwave irradiation. The microwave radiation increases iron reaction rate and surface activity, thus enhancing the chlorobenzene removal. The microwave-induced iron particles cause the chlorobenzene activation energy to drop 34.0% for micronscale iron and 16.1% for nano-scale zero-valent iron. They can remove 13.6 times more chlorobenzene for micro iron, and 3.6 times more chlorobenzene for nano iron. We have demonstrated that the microwave-induced nano-scale iron particles are effective in treating toxic organic substances as demonstrated in this laboratory study.
