	Abstract:In this paper, the adsorption of uranium by graphene oxide was investigated. The effect of pH, contact time, concentration of uranium and temperature on the adsorption capacity of uranium was determined. The graphene oxide (GO) was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), powder X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and infrared spectra (FTIR). FTIR spectra indicated that carboxyl and alkoxy groups existed on the surface of GO, which involved in uranium adsorption. The adsorption kinetics of U(VI) followed pseudo first-order kinetic model. The adsorption isotherm conformed to Tempkin model. The adsorption process is spontaneous and exothermic.

	Abstract:Continuous ozonation can inactivate indigenous microbes due to the disinfection capability of ozone, which may affect subsequent bioremediation of soils. This study investigated the efficiency of removing polycyclic aromatic hydrocarbons from soils using intermittent ozonation technique, where ozone was sparged through the soil column every alternate day, resulting in shorter ozonation time for each ozonation circulation than continuous ozonation. The results showed that 85% Phe, 94% Ant, 76% Flu, 87% Pyr, and 91% BaP were removed on 32 d in continuous ozonation treatment, while 90% Phe, 84% Ant, 78% Flu, 81% Pyr, and 96% BaP were removed on 32 d in intermittent ozonation treatment, indicating both intermittent and continuous ozonation can effectively remove polycyclic aromatic hydrocarbons from soils. Fluorescien diacetate hydrolysis results indicated that the total microbial activity of intermittent ozonation was significantly (p < 0.05) higher than that of continuous ozonation treatment at 8, 16, 24 and 32 d. The toxicity bioassay of soil extracts showed that the relative luminescence increased from 5 to 30% at 8 d, without significant (p > 0.05) increase at 32 d in continuous ozonation treatment, while it increased to 61% at 32 d in intermittent ozonation treatment, indicating intermittent ozonation was more effective than continuous ozonation for the detoxification of soils contaminated with polycyclic aromatic hydrocarbons. It suggested that the both treatments were equally effective at removing polycyclic aromatic hydrocarbons from soil, but intermittent ozonation was better than continuous ozonaiton for further detoxification and maintaining the total microbial activity of soil.

	Abstract:Rapid developments of the Pearl River Delta (PRD) region in recent decades have resulted in the increasingly serious environmental pollution in and around the region. The 6 priority phthalate esters (PAEs) were investigated in surface water and sediment from seven estuaries within the PRD for assessing the ecological risk to the aquatic environment. The concentration of Σ6PAEs in surface water ranged from 1.26 to 28.1 μg L-1, with a mean concentration of 16.5 μg L-1. It was from 1.56 to 31.2 μg g-1 dw in sediment, with a mean concentration of 9.72 μg g-1 dw. DMP, DBP and DEHP were found in all samples, and they were the predominant PAEs in the region. The distribution of PAEs showed that more serious pollution was found in Humen and the consumption of PAEs was increased in the most recent years in the PRD region. Risk quotient of detected PAEs to the relevant aquatic organisms of fish, daphnids and algae indicated the possible threat for the aquatic environment due to the presence of DBP and DEHP.

	Abstract:There is a high interest in speciation of tributyltinchloride(TBT) in environment samples, such as seawater, due to the influence in the transmission of the contamination in the trophic chain. The environmental impact of organotin compounds has given particulate importance to analytical studies. This paper reports that applying a molecular imprinting technolgy with liquid chromatography-tandem mass spectrometry (LC-MS/MS) to this field. The imprinted polymer has been synthesised by the non-covalent free redical approach using acrylamide(AM) as monomer in the presence of TBT as template molecule in acetonitrile solvent. The ability of the polymer synthesised to retain and distinguish TBT has been evaluated and optimized. The analytical characteristics included linearity（10-100000μgL-1）, a pre-concentration factor of 100, and detection limit of 0.01 μgl-1.

	Abstract:In this paper, ROM model, a kinetics model on organic substrate removal, was established on the basis of material balance in submerged membrane bioreactor (SMBR). According to the model, the organic substrate removal rate is determined by not only the organic substrate concentrations in influent and effluent, hydraulic retention time (HRT), but also the organic substrate concentration removed by membrane module and sludge retention time (SRT). Meanwhile, SRT and the maximum value of mixed liquor volatile suspended solids (MLVSS) without discharging sludge can be determined as well as the concentration of MLVSS can be predicted in reactor. Brewery wastewater was chosen and examined to verify the model and the results showed that the experimental data were coincident with the calculating data.

	Abstract:To assess the CT toxicity to plants in soil, the antioxidative performance and the level of lipid peroxidation in wheat seedlings under CT stress were investigated by simulated experiments. The results indicated that: 1) The trend of activity of POD and SOD went to conformity, which were activated by CT ranging from 0.32 to 1.60 mgokg-1 and were inhibited by CT above 1.60 mgokg-1. 2) Under CT stress, the antioxidative performance of wheat seedlings was firstly activated within a short-term period, and then inhibited. 3) The lipid peroxidation of wheat seedlings wasn't obvious at CT concentration lower than 0.32 mgokg-1. But when CT concentration ranging from 0.32 to 1.60 mgokg-1, the MDA content increased obviously and the plasmalemma lipid could not be protected from peroxiding by activated POD and SOD. 4) At medium and late stage, the POD and SOD activity had a decreasing trend with increasing CT concentration, while the MDA content had significant positive correlation (with 99% confidence interval) with CT concentration.

	Abstract:IThis paper reports experimental investigations on plasma-induced styrene emission abatement in air at room temperature (24±2 ℃) and pressure. Tests were performed with a 1000 m3/h plasma system under DC corona discharge. It is observed that styrene destruction in DC glow discharge is negligible in contrast to streamer corona. When relative humidity (RH) is in the range of 30 %-80 %, the energy consumption for styrene decomposition rises with RH value. The energy coefficient β value becomes larger with increasing either RH or the initial styrene concentration for RH in 30 %-80 % and the concentrations within 90-1000 ppm, respectively. With regards to those dependence sensitivity, the lower the concentration, the more sensitive to the RH value. Under optimal condition (100 ppm initial concentration, 35 %RH), the β value is 18.73 J/L.

	Abstract:Hydrothermal technology is a core environmental protection technique, which can be used in the waste water treatments and biomass conversion. In this paper, a novel idea is proposed to produce formic and acetic acids from wastewater containing phenolic compounds by alkali hydrothermal oxidations. The effects of major parameters on the yields of formic acid and acetic acid, including reaction temperature, reaction time, oxygen supply and types of alkali catalysts, were investigated. The results indicated that the optimum conditions for the production of formic and acetic acids were as follows: reaction temperature of 300 C, reaction time of 90 s, H2O2 supply of 60% and NaOH concentration of 1.5 mmoL. In the optimum condition the yields of formic acid and acetic acid reached 4.8% and 23.5%, respectively. In addition, the effect of different alkalis on the yields of formic and acetic acids was also investigated. The results showed that compared with the addition of NaOH, the addition of KOH showed a more pronounced effect on improving the yield of acetic acid. This research indicated that high value-added formic and acetic acids can be recovered as resources through hydrothermal oxidation of phenolic wastewater, and thus hydrothermal oxidation has a high potential for converting phenolic compounds in wastewater into value-added products.

	Abstract:Land resource is finite and precious in the development of society .Environment costs which contribute to human welfare, both directly and indirectly, are often neglected in the evaluation of land use. This paper ，from the view of the land use，presents a study of value assessment including both environmental costs and economic value. By multiplying a set of ecosystem services with a set of corresponding shadow prices which are based on published studies and a few original calculations, the current environment costs (EC) can be estimated. Also the economic value (EV) produced by land use is calculated in this paper. Then functions assessing the real value of land use can be obtained by considering the environment costs and economic value. Application of this study on a land use example is shown lately. At last, how to achieve the sustainable development with the finite land resource is discussed.

	Abstract:A study was carried on the effectiveness of green roofs to abate Storm water using computer simulation. In this study, the storm water performance was simulated for a modular block green roof using a packaged soil moisture simulation, HYDRUS-1D, with simulation results verified by study site data. Simulations were run using HYDRUS-1D for 24-h design storms to determine peak flow, retention and detention time for runoff. Storm data collected as part of a green roof study were used to validate HYDRUS-simulated runoff. The study site consisted of a 37 m2 (400 ft2) modular block green roof containing engineered soil and vegetation including several Sedum species. The study revealed that rainfall depth per storm strongly influences the performance of green roofs for storm water abatement, providing complete retention of small storms (<2.54 cm) and detention for larger storms, assuming the measured average moisture content (10%) as the antecedent condition.
