a b s t r a c tThe transformation of organic matter during anaerobic digestion of mixtures of energetic crops, cow slurry, agro-industrial waste and organic fraction of municipal solid waste (OFMSW) was studied by analysing different samples at diverse points during the anaerobic digestion process in a full-scale plant. Both chemical (fiber analysis) and spectroscopic approaches ( 13 C CPMAS NMR) indicated the anaerobic digestion process proceeded by degradation of more labile fraction (e.g. carbohydrate-like molecules) and concentration of more recalcitrant molecules (lignin and non-hydrolysable lipids). These modifications determined a higher degree of biological stability of digestate with respect to the starting mixture, as suggested, also, by the good correlations found between the cumulative oxygen uptake (OD 20 ), and the sum of (cellulose + hemicellulose + cell soluble) contents of biomasses detected by fiber analysis (r = 0.99; P < 0.05), and both O-alkyl-C (r = 0.98; P < 0.05) and alkyl-C (r = À0.99; P < 0.05) measured by 13 C CPMAS NMR.

“…laboratories and replicates number, was decided on the basis of the availability of laboratories to perform the requested analyses, and taking into consideration the complexity of the sampling procedure, samples storage and samples transport. In any case, some previous authors report good results in precision determination involving only three laboratories (Scaglia et al, 2007;Bocchi et al, 2008).…”

“…Precision measurements were determined for RDRI (Table 2) and the results were reported on a relative basis, i.e., the relative standard deviations of repeatability (RSD r ) and reproducibility (RSD R ) (Scaglia et al, 2007). The precision levels for all samples analyzed, ranged from 16.7% to 17.8% and from 17.5% to 23.9% for RSD r and RSD R , respectively (Table 2), (variability measured within and between different laboratories).…”

“…The SOUR can be used in a simple static test to assess the composition stability and toxicity of wastewater (Scaglia et al 2007;Yin et al 2007). Therefore, in this paper, coking wastewater was electrolyzed for 15, 30, and 45 min under the optimal conditions.…”

Effluent of biotreated coking wastewater comprises hundreds of organic and inorganic pollutants and has the characteristics of high toxicity and difficult biodegradation; thus, its chemical oxygen demand cannot meet drainage standards in China. A boron-doped diamond anode was selected for advanced treatment of biotreated coking wastewater, and considering the efficiency of the removal of total organic carbon and energy consumption, optimal conditions were obtained as current density of 75 mA cm(-2), electrolysis time of 1.5 h, and an electrode gap of 1.0 cm in an orthogonal test. Effluent characteristics were investigated at different electrolysis times. The ratio of the 5-day biochemical oxygen demand (BOD5) to the chemical oxygen demand increased from an initial value of 0.05 to 0.65 at 90 min. Fluorescence spectra were used to evaluate the evolution of refractory organics. Two fluorescence peaks for raw wastewater, corresponding to an aromatic protein-like substance II and humic acid-like substance, weakened at 30 and at 90 min, only the former was detected. The specific oxygen uptake rate was used to assess effluent toxicity, and an obvious inhibition effect was found at 15 min; then, it was significantly faded at 30 and 45 min. The BOD5/NO3 (-)-N ratio increased from an initial value of 0.48 to 1.25 at 45 min and then gradually dropped to 0.69 at 90 min. According to the above effluent characteristics, it is strongly suggested that electrochemical technology using boron-doped diamond anodes is combined with biological denitrification technology for the advanced treatment of biotreated coking wastewater.
