Ultrasonic and ozone pre-treatment technologies were employed in this study to improve the anaerobic digestion efficiency of pharmaceutical waste activated sludge. The sludge solubilisation achieved 30.01% (150,000kJ/kg TS) and 28.10% (0.1g O3/g TS) after ultrasonic treatment and ozone treatment. The anaerobic biodegradability after ultrasonic treatment was higher compared to ozonation due to the higher cumulative methane volume observed after 6days (249ml vs 190ml). The ozonated sludge released the highest concentration of Cu2+ into the liquid phase (6.640mgL-1) compared to 0.530mg/L for untreated sludge and 0.991mg/L for sonicated sludge. The acute toxicity test measured by luminescent bacteria showed that anaerobic digestion could degrade toxic compounds and result in a reduction in toxicity. The main mechanism of action led to some differences in the treated sludge exhibiting higher potential for methane production from pharmaceutical waste sludge with ultrasonic treatment. © 2015 Elsevier Ltd.

The interaction between carbamazepine (CBZ) and dissolved organic matter (DOM) from three zones (the nearshore, the river channel, and the coastal areas) in the Yangtze Estuary was investigated using fluorescence quenching titration combined with excitation emission matrix spectra and parallel factor analysis (PARAFAC). The complexation between CBZ and DOM was demonstrated by the increase in hydrogen bonding and the disappearance of the C=O stretch obtained from the Fourier transform infrared spectroscopy analysis. The results indicated that two protein-like substances (component 2 and component3) and two humic-like substances (component 1 and 4) were identified in the DOM from the Yangtze Estuary. The fluorescence quenching curves of each component with the addition of CBZ and the Ryan and Weber model calculation results both demonstrated that the different components exhibited different complexation activities with CBZ. The protein-like components had a stronger affinity with CBZ than did the humic-like substances. On the other hand, the autochthonous tyrosine-like C2 played an important role in the complexation with DOM from the river channel and coastal areas, while C3 influenced by anthropogenic activities showed an obvious effect in the nearshore area. DOMs from the river channel have the highest binding capacity for CBZ, which may ascribe to the relatively high phenol content group in the DOM. © 2016 Springer-Verlag Berlin Heidelberg

Trace metals in leachates are forced to be removed with the implement of the latest Chinese standards of landfill pollution control (GB-16889, 2008), and understanding the speciation distribution processes is important for the development of the leachate treatment process. In this work, evolution processes of trace metal speciation were investigated according to the size fractions, hydrophobic/hydrophilic fractions, and geochemical species with the disposal time. The main trace metals, that is, Pb, Ni, Cr Cu, and Zn, were around 0.04–0.52 mg Pb/L, 0.24–1.22 mg Ni/L, 0.12–0.86 mg Cr/L, 0–0.28 mg Cu/L, and 0.58–1.98 mg Zn/L in leachates with the disposal ages of 2–12 years. Pb was found to predominate in suspended solids, with the percentage of 46–100%, and the dominant fraction of Ni and Zn was in dissolved fractions, with the percentage of 28–83 and 34–67%, respectively, while Cr and Cu scattered between suspended solid and dissolved fractions. The predominated geochemical species of Pb, Ni, Zn, and Cu was Me dissolved organic matter and Me CO3, while Cr was dominated as hydroxide complexations. For the hydrophobic distribution in leachates, the main part of Pb, Ni, Cr, and Cu was presented as hydrophobic fractions, with the percentage of >50%, while Zn predominated in the hydrophilic fractions. The evolution processes of trace metals are dependent on both the metals’ nature and the landfill conditions greatly, and the corresponding treatment process should be changed with the landfill ages. © 2015 Balaban Desalination Publications.

Persistent organic pollutants (POPs) are the urgent risk for landfill, and should be considered before the landfill reclamation and resource. In this work, the distribution pattern of selected POPs in landfill and their ecological risks were investigated and assessed. The Σ20OCPs, Σ16PAHs and Σ19PCBs were around 157.4-329.2, 4103-19,190, and 79.1-340.3μgkg-1 in aged refuses, with the mean value of 206.6, 8645.4, and 155.1μgkg-1. While those in soil covers were only 6.3-75.4, 125.5-515.3 and 2.6-43.4μgkg-1, with the mean value of 33.7, 257.7, and 24.0μgkg-1, respectively. The maximum OPCs, PHAs and PCBs were in aged refuse with 13, 7, 10 disposal years. Whereas, the corresponding top content in soil covers were in 10, 13 and 16years, meaning that aged refuses were not the direct source for soil covers. Among 20 OCPs measured, α-HCH, δ-HCH, Dieldrin, and Endrin were presented in all aged refuses, with the mean concentration of 93.6, 52.1, 3.9 and 4.7μgkg-1, respectively. For PAHs, PHE, FLU and PYR were the main composition, and reached to 1535, 1224, 1187μgkg-1. The Σ7CarPAHs occupied around 33.3-49.9% of total Σ16PAHs tested, and could be used as the indictor for PAHs pollutant in landfill. PCB-5 content was around 40.7-263.3μgkg-1 in aged refuses, and occupied around 51.5-81.8% of Σ19PCBs measured. The HCHs and DDTs in aged refuses were below the national standard GB15618-1995, and the corresponding Σ19PCBs concentrations met the standard of GB 13015-91, suggesting that aged refuse are accepted for the further utilization process. © 2016 Elsevier Ltd.

Arsenic exists ubiquitously in the environment and has been proved to be of great harm to human health. In this study, a series of Fe-La composite (hydr)oxides were synthesized via a facile coprecipitation for effective As(V) removal from aqueous solution. A variety of techniques including BET surface area measurement, powder XRD, SEM, and XPS were employed to characterize the synthetic Fe-La composite (hydr)oxides. Fe-La composite (hydr)oxides grains were formed via aggregation of primary nanoparticles. With an increase in La content, the specific surface area of Fe-La composite (hydr)oxides decreased, but the pore diameter, the pore volume and the grain size of Fe-La composite (hydr)oxides increased gradually. Rapid As(V) adsorption on the synthesized composite oxides was achieved and the adsorption was well fitted by the pseudo-second-order equation. The adsorption isotherms could be well described by Langmuir equation and the maximal adsorption capacity of Fe-La composite (hydr)oxides can reach 368. mg/g. The As(V) removal was pH-dependent and decreased with an increase in pH value, especially in alkaline condition. Under acidic and neutral conditions, As(V) removal was mainly achieved by both precipitation and adsorption. By contrast, adsorption is the only mechanism for As(V) removal in alkaline condition. The results indicate that the Fe-La composite (hydr)oxides could be potentially attractive adsorbents for As(V) removal. © 2014 .

Short-chain and medium-chain chlorinated paraffins (SCCPs and MCCPs) were measured in sediments from ponds, rivers and tributaries, and an estuary, as well as a sediment core in the Pearl River Delta (PRD), South China, to comprehensively investigate the spatial and temporal distributions of CPs. The concentrations of SCCPs and MCCPs in sediment were varied from 320 to 6600 ng/g and from 880 to 38 000 ng/g, respectively. Elevated CP concentrations were found in pond sediments (means of 2800 and 21 000 ng/g for SCCPs and MCCPs) in the e-waste recycling area and in river sediments (means of 1200 and 3900 ng/g for SCCPs and MCCPs) in the highly industrialized areas. The significant positive correlations between SCCP concentration and MCCPs/SCCPs in the highly industrialized areas reflected the emission of local industry activities, while the significant negative correlations in the low industrial activity areas could be linked to long-range transportation of CPs. An increased abundance of short chain and low chlorinated congeners was observed in the low industrial activity areas compared to the industrialized areas. The preferred transportation of short chain and low chlorinated congener CPs and the dechlorination of higher chlorinated congeners CPs were the most likely reasons. The vertical profile of CPs in the sediment core indicated a rapid increase in the usage of CPs and a shift to more MCCPs in recent years. The decreased chlorine content of CPs with increasing sediment depth indicated the possibility of dechlorination of higher chlorinated congeners (Cl 9 and Cl 10) after deposition in sediments with greater dechlorination potential for short chain CPs than long chain CPs. © 2011 American Chemical Society.

Arbuscular mycorrhizal fungi (AMF) can alter the dynamics of soluble nitrogen in paddy field soils by promoting nitrogen assimilation by rice. However, it is unknown whether this affects N2O emissions from rice paddies. This study was designed to assess the effects of AMF on N2O emissions by analyzing the relationships between AMF and the parameters affecting N2O emissions. Path analysis was used to quantitatively partition the direct and indirect effects of different parameters on N2O emissions. Results showed that N2O emissions were controlled by environmental pathways (transpiration, evaporation, and precipitation affecting soil water content) and biotic pathways (soluble nitrogen assimilation by the rice, which varies according to rice biomass). Under different water conditions, the contributions of the two pathways to N2O emissions varied strongly. During the flooding stage, the environmental pathways were dominant, but inoculation with AMF promoted the contribution of the biotic pathway to the reduction of N2O emissions. During the draining stage, the environmental pathways were dominant in the non-inoculated treatment, but inoculation made the biotic pathways dominant by increasing the biomass of rice. During the growing stage, N2O emissions from inoculated soil (17.9-492.9 μg N2O-N m-2 h-1) were significantly lower than those in non-inoculated soil (22.1-553.1 μg N2O-N m-2 h-1; p<0.05). Consequently, inoculating with AMF has the potential for mitigating N2O emissions from rice paddies. © 2015 Springer International Publishing.
