Abstract
With a large amount of domestic sewage and industrial wastewater discharged into the water bodies, sulfur-containing organic matter in wastewater produced volatile organic sulfide, such as dimethyl trisulfide (DMTS) through microorganisms, caused the potential danger of drinking water safety and human health. At present, there is still a lack of technology on the removal of DMTS. In this study, the ultraviolet/peroxymonosulfate (UV/PMS) advanced oxidation processes was used to explore the degradation of DMTS. More than 90% of DMTS (30 µg/L) was removed under the conditions of the concentration ratio of DMTS to PMS was 3:40, the temperature (T) was 25 ± 2℃, and 10 min of irradiation by a 200 W mercury lamp (365 nm). The kinetics rate constant k of DMTS reacting with hydroxyl radical (HO·) was determined to be 0.2477 min-1. Mn2+, Cu2+ and NO3- promoted the degradation of DMTS, whereas humic acid and Cl- in high concentrations inhibited the degradation process. Gas chromatography-mass spectrometry was used to analyze the degradation products and the degradation intermediates were dimethyl disulfide and methanethiol. Density functional theory was used to predict the possible degradation mechanism according to the frontier orbital theory and the bond breaking mechanism of organic compounds. The results showed that the SS, CS and CH bonds in DMTS molecular structure were prone to fracture in the presence of free radicals, resulting in the formation of alkyl radicals and sulfur-containing radicals, which randomly combined to generate a variety of degradation products.

Abstract
Abstract
To overcome the lack of dissolved oxygen in high-density aquaculture water, a hydrogen peroxide-acrylic resin inclusion complex with sustained oxygen releasing effect was designed and prepared. The resin was synthesized by emulsion polymerization of acrylic acid, methyl methacrylate and butyl acrylate in a mass ratio of 2: 3: 5, and neutralized with sodium hydroxide solution by 50%. The resin solution was mixed in a mixture of urea and 30% hydrogen peroxide solution (CO(NH2)2: H2O2, 1: 1, mol: mol), and dried at 40 °C for 4 h to obtain the hydrogen peroxide-acrylic resin inclusion complex. The product with 4.0% resin by mass of hydrogen oxygen solution, could release oxygen for 92 h in pond water. After optimization by adding a small amount of NaCl, Na2SO4, and EDTA, it was mixed with calcium carbonate and magnesium stearate in a mass ratio of 5: 4: 0.9, and pressed into tablets (1.2 × 0.6 cm, 0.99 g). One tablet in 50 L simulated micro ecosystem aquaculture water with 20 of Carassius auratus fish could release oxygen for 116 h and brought fish with 83.3% of survival rate higher than 51.7 and 70.0% of blank and sodium percarbonate groups.

Abstract
Swampy/septic odor caused by various sulfides is one of the most frequently encountered odor problems in drinking water. However, even though it is much more offensive, few studies have specifically focused on swampy/septic odor compared to the extensively studied musty/earthy problems. In this work, four sulfide odorants, diamyl sulfide (DAS), dipropyl sulfide (DPS), dimethyl disulfide (DMDS) and diethyl disulfide (DEDS), were selected to evaluate the treatment performance of different oxidation processes in drinking water. The results demonstrated that DMDS, DEDS, DPS and DAS could be oxidized effectively by KMnO4, NaClO and ClO2. The oxidation processes could be well described by the second-order kinetic model, in which k values of selected sulfides followed the order DMDS≈DEDS ≪ DPS≈DAS. As for the three oxidants, the order of reactivity was KMnO4 ≪ ClO2 < NaClO, which was also verified in raw water. The results of oxidation treatability, reaction kinetics and mechanisms confirmed that the characteristics of the central sulfur atom rather than the side chain is the decisive factor in controlling the oxidation rate and transformation pathway of sulfides. The transformation products and pathways were significantly different for the three oxidants. Sulfones (DPSO, DASO) were always formed by cycloaddition reactions during KMnO4 oxidation, yet recombination reactions proceeded during ClO2 oxidation and formed more products, such as MADS, DADS and EADS. Density functional theory (DFT) calculations confirmed that the differences in transformation pathways were caused by the variations in the activity of the oxidants and sulfides. Finally, NaClO was certified as the most effective oxidant for controlling sulfide odorants in drinking water treatment.

Abstract
In this work, a simulation tool was developed for hydrogen sulphide (H₂S) removal in an alkaline solution in packed columns working at countercurrent. Modelling takes into account the mass-transfer enhancement due to the reversible reactions between H₂S and the alkaline species (CO(²⁻)(3), HCO⁻(3), and HO⁻) in the liquid film. Many parameters can be controlled by the user such as the gas and liquid inlet H₂S concentrations, the gas and liquid flow rates, the scrubbing liquid pH, the desired H₂S removal efficiency, the temperature, the alkalinity, etc. Since the influence of the hydrodynamic and mass-transfer performances in a packed column is well known, the numerical resolutions performed were dedicated to the study of the influence of the chemical conditions (through the pH and the alkalinity), the temperature and the liquid-to-gas mass flow rate ratio (L/G). A packed column of 3 m equipped with a given random packing material working at countercurrent and steady state has been modelled. The results show that the H₂S removal efficiency increases with the L/G, the pH, the alkalinity and more surprisingly with the temperature. Alkalinity has a very significant effect on the removal efficiency through the mass-transfer enhancement and buffering effect, which limits pH decreasing due to H₂S absorption. This numerical resolution provides a tool for designers and researchers involved in H₂S treatment to understand deeper the process and optimize their processes.

Abstract
To assess the potential of ferric hydroxide (FH) to reduce odour emission from dewatered sewage sludge with a moisture of approximately 86%, odour reduction was evaluated using an electronic nose and measurements of odorous compounds (hydrogen sulphide, ammonia and volatile fatty acids (VFAs)). The sulphur species including sulphate, acid-volatile sulphide (AVS), Cr(II)-reducible sulphide (CRS) and elemental sulphur (ES), were analysed by a modified cold diffusion sequential extraction method before and after anaerobic incubation. Within 32 days, 69.3, 83.8 and 88.6% of the odour (or 81.3, 93.7 and 97.5% of hydrogen sulphide) were eliminated, respectively, at the rates of 0.05, 0.10 and 0.25% (wt) of FH. The sulphur species analysis indicated that FeS, FeS2 and a small portion of S0 were formed by FH-sulphide reaction. This study also found that the relationship between odour and H2S concentrations could be well expressed by Steven's law. We believe that FH can be a cost-effective reagent for sludge odour control in sewage treatment processes.

Abstract
The oxidation of cellular thiol-containing compounds, such as glutathione and protein Cys residues, is considered to play an important role in many biological processes. Among possible oxidants, hydrogen peroxide (H(2)O(2)) is known to be produced in many cell types as a response to a variety of extracellular stimuli and could work as an intracellular messenger. This reaction has been reported to proceed through a S(N)2 mechanism, but despite its importance, the reaction is not completely understood at the atomic level. In this work, we elucidate the reaction mechanism of thiol oxidation by H(2)O(2) for a model methanethiolate system using state of the art hybrid quantum-classical (QM-MM) molecular dynamics simulations. Our results show that the solvent plays a key role in positioning the reactants, that there is a significant charge redistribution in the first stages of the reaction, and that there is a hydrogen transfer process between H(2)O(2) oxygen atoms that occurs after reaching the transition state. These observations challenge the S(N)2 mechanism hypothesis for this reaction. Specifically, our results indicate that the reaction is driven by a tendency of the slightly charged peroxidatic oxygen to become even more negative in the product via an electrophilic attack on the negative sulfur atom. This is inconsistent with the S(N)2 mechanism, which predicts a protonated sulfenic acid and hydroxyl anion as stable intermediates. These intermediates are not found. Instead, the reaction proceeds directly to unprotonated sulfenic acid and water.

Abstract
Gaseous dimethyl sulphide (DMS) was eliminated in a biotrickling filter with Thiobacillus thioparus grown in polyurethane foam cubes as carrier material. The temperature, pH and empty bed residence time of the gas were maintained at 30 degrees C, 7.0 and 40 s, respectively. In the first 45 days, DMS loads of around 2.0 gDMS m(-3) h(-1) were fed to the BTF to adapt T. thioparus to DMS consumption, attaining close to 100% removal efficiency (RE) on day 46, and the maximum elimination capacity (EC) was 4.0 gDMS m(-3) h(-1) with a RE of 77%. The overall performance was enhanced by adding a nitrogen-enriched (9x) medium but was negatively affected by high superficial liquid velocity (8.18 m h(-1)) and high pH (>7.5). Sulphate concentrations (up to 10 g L(-1)) showed no effect. The system supported shock loads up to 58 gDMS m(-3) h(-1) with increased elimination. With nitrogen-enriched medium and a pH of 7.0 it was possible to increase the EC of DMS up to a maximum of around 23 gDMS m(-3) h(-1) with 65% RE.

Abstract
Dimethyl disulphide (DMDS) removal was investigated in a compact scrubber (hydraulic residence time approximately 20ms), composed of a wire mesh packing structure where liquid and gas flow at co-current and high gas superficial velocity (>12m s(-1)). In order to regenerate the scrubbing liquid and to maintain a driving force in the scrubber, ozone and hydrogen peroxide were added to water since they allow the generation of nonselective and highly reactive species, hydroxyl radicals HO(). Three ways of reagent distribution were tested. The influence of several parameters (liquid flow rate(s), ozone flow rate, pH and reagent concentrations) was investigated. The best configuration was obtained when ozone is transferred in the scrubbing liquid before introduction at the top of the scrubber simultaneously with the hydrogen peroxide solution, allowing to generate hydroxyl radical in the scrubber. With this configuration, DMDS removal could be increased from 16% with water to 34% at the same gas and liquid flow rates in the scrubber showing the potentiality of advanced oxidation process.

Abstract
Sulfur-containing compounds are one kind of odorant found in sewage treatment works, composting plants, refuse storage and transfer, landfill sites, and associated with various industries. In the present research, the reaction kinetics of ferrate(VI) (Fe(VI)O4(-), Fe(VI)) with 2-mercaptobenzothiazole (MBT), thiosemicarbazide (NH2NHC(S)NH2, TSC), and thiourea dioxide (NH2C(SO2)NH2, TUDO) were studied under alkaline conditions. Stoichiometryof Fe(VI) oxidation with hydrogen sulfide (H2S), TSC, and methyl mercaptan (CH3SH) were determined at neutral and alkaline pH (7.0-11.0). Stoichiometric molar ratios ([Fe(VI):[S]) were determined to be 2.5, 2.0, and 4.6 for sulfide, TSC, and CH3SH, respectively, at pH 9.0. TUDO and methyl sulfonic acid (CH3SO3H) were identified to be the main intermediates of TSC and CH3SH reactions with Fe(VI), respectively, at pH 9.0, while sulfate was one of the final products. A reaction scheme is given to explain the intermediates and products formed in the CH3SH degradation by Fe(VI). Experiments were also conducted to evaluate the odor emission of digested sludge from sewage treatment works in terms of chemical concentration and also odor concentration affected by the Fe(VI) dose. The potential of using Fe(VI) to achieve odor control in sludge treatment is briefly discussed.

Abstract
To slow down the hydrogen peroxide decomposition in basic aqueous conditions, the addition of stabilizers and co-stabilizers in the scrubbing solution was investigated. Results found with sodium silicate (Na2SiO3) were quite promising but several problems still remained. Based on these observations, this study focused on the research of a better stabilizer. Several ways were investigated: the use of silicate solutions employed in pulp industries, the addition of co-stabilizers to sodium silicate, or the use of an another stabilizer (the poly-alpha-hydroxyacrylic acid). Experiments revealed that the poly-alpha-hydroxyacrylic acid is the best stabilizing compound.
