“…In addition to membrane technologies, the applications of advanced oxidation processes (AOPs), such as catalytic ozonation (He et al, 2013), Fenton/photo-Fenton oxidation (Nousheen et al, 2014), and photocatalytic oxidation involving UV/H 2 O 2 (Shon et al, 2007;González et al, 2013) have been recognized as high potential technologies for wastewater reclamation and water reuse. However, AOPs are normally used to partially oxidize non-biodegradable OM with high molecular weight or recalcitrant OM to more biodegradable compounds due to the large consumption of energy and chemicals for complete oxidation and mineralization.…”

Alkali weight-reduction is a necessary process to remove the sea component (polyesters) by alkali for 'sea-island' microfiber manufacture, in which large amounts of wastewater with high content of Na 2 SO 4 , ethylene glycol (EG) and terephthalic acid (TPA) were produced, thus making the traditional activated sludge method being invalid for wastewater treatment. To address this issue, a combination method was employed to treat the wastewater, i.e. the wastewater was treated by Fenton oxidation then followed by bioaugmentation process, simultaneously, the degradation characteristics of combined method were investigated in detail. In the first stage, the wastewater was treated by optimised Fenton's reagent, some stable compounds were found to degrade into metastable molecules; In the second stage, a new halotolerant bacteria, which could efficiently degrade EG, was isolated from the soil and added into the activated sludge to further degrade the oxidized wastewater. The results indicated that wastewater was treated by this combination method, the chemical oxygen demand (COD) and total organic carbon (TOC) decreased from 9070 and 4656.9 mgO 2 /L to 150 and 13.05 mgO 2 /L, showing an obvious positive effect. Moreover, the two-dimensional fractal dimension (D 2f) of activated sludge was also found to be enhanced, again demonstrating the positive effect among bacteria, activated sludge and chemical reaction.

“…Among the physicochemical treatments for biodegradability enhancement, advanced oxidation processes (AOPs) have been regarded as an efficient approach to recalcitrant organic matter decomposition [9,10]. Fenton oxidation as one of the AOPs has been extensively studied and used in mature landfill leachate treatment [11][12][13].…”

In order to verify the feasibility of Fe/C microelectrolysis-Fenton oxidation for mature landfill leachate treatment in industrial application, this study conducted the treatment processes at full-scale by physicochemical and spectral characterization. The full-scale studies showed that 48.17% of the dissolved organic carbon (DOC) and 42.27% of the dissolved organic nitrogen (DON) were removed by the microelectrolysis-Fenton oxidation process, respectively. Spectra analysis further suggested that the mature leachate was mainly composed of tryptophan-like and fulvic-like compounds. The combination of microelectrolysis and Fenton oxidation efficiently decomposed the aromatic C=C into carboxyl-C and decreased the molecular size of DOC, resulting in a dramatic reduce (97.1%-98.3%) of the fluorescence intensity. The DON removal by microelectrolysis-Fenton oxidation likely associated with the NH2-decomposition of tryptophan-like and aromatic compounds into NO3-N. The tryptophan-like compounds may play a dominant role in Ba binding, while Pb and Cd were likely bound to both the tryptophan-like and fulvic-like compounds. Above 60% of the heavy metals were removed in the microelectrolysis-Fenton oxidation section. Results above confirmed the effectiveness of Fe/C microelectrolysis-Fenton oxidation for mature landfill leachate treatment in industrial application.
