摘要：
Arbuscular mycorrhizal fungi (AMF) are symbiotic partner of plants and are important for survival and growth of plants under stresses. Three AMF species were inoculated to Lolium Perenne L. and plant performances in uranium contaminated and uncontaminated soils. The results show that (1) AMF inoculation improved the uranium resistance of Lolium Perenne, and increased photosynthetic pigments and soluble protein content and decreased MDA content were found in AMF inoculation treatments. (2) Antioxidant system enzyme activity in vivo Lolium Perenne also increased. (3) Uranium accumulation characteristics varied in three AMF inoculation treatments, indicating that different mechanisms of AMF species may be involved in response to uranium stress.

摘要：
In order to realize the process mechanism that Shewanella oneidensis(S. oneidensis) reduced uranium(VI), and improve its reduction effect, the reduction mechanisms of uranium with S. oneidensis were studied by FTIR, SEM, EDS. The results show that after the S. oneidensis reduction of U(VI), the cell surface morphology is changed, the gaps and caverns on S. oneidensis surface decrease and more uncrystalmini grains through electron appear, which are binding each other. Much of new crystal structures were generated on the surface of cell. K+ and PO43+ were involved in the process of U(VI) reduction. FT IR spectra analysis indicated that the main groups of S. oneidensis were association of hydroxyl, phenolic hydroxyl, amidogent, halogenated hydrocarbon, carboxyl in the process of U (VI) reduction.
摘要：
Phenolic wastewater comes mainly from coking, gas, and petrochemical plants, and other industrial sectors, as well as petroleum cracking ethylene, synthetic phenol, poly Thalidomide fibers, organic pesticides, and the phenolic resin production process. Phenolic compounds are monitoring our priority persistent organic compounds, having already been included in the column of carcinogenic single ring aromatics. In this paper, catalytic supercritical water gasification was applied to treat the phenolic wastewater. The influence of alkali on the gasification of phenolic wastewater with NaOH as catalyst at 580 degrees C, 27MPa was investigated. The results showed that the NaOH addition increased H-2 fraction and gas yield. The reaction mechanism was analyzed.
摘要：
The different values of pH, EPS dosage, initial uranium concentration, dialysis temperature and other factors, were investigated of anaerobic sludge extracellular polymer (EPS) on U (VI) in wastewater by adsorption effect. The results show that, the best pH of EPS adsorption of uranium is 6, when the initial concentration of uranium is 20mg/L, EPS dosage is 56.1 g/L, the removal rate can reach 98.3%. The maximum adsorption capacity of U (VI) is 0.891mg/g EPS.

摘要：
Fe-immobilized bentonite, prepared with bentonite and FeCl3 was used for the adsorption of uranium(VI) in this study, solution pH, ion strength, contact time and temperature were investigated, structural characterization of Fe-immobilized bentonite was assayed by X-ray Diffraction and Fourier Transform Infrared Spectroscopy. Results indicated that the adsorption capacity were strongly affected by the solution pH and ion strength, the adsorption efficiency was 91.8% when pH value was 6 and ion strength was 0.01 mol•L-1, higher or lower pH did not favor the U(VI) adsorption. The adsorption mechanism was discussed by the views of reactive kinetics and thermodynamics along with Scanning Electron Microscope. The adsorption kinetics process was fitted well with the second-order kinetic equation, when the initial U(VI) concentration was less than 38.08mg/L, Langmuir equations could describe the adsorption isotherm of U(VI) well with the maximum adsorption capacity of 169.5mg/g at 303K

摘要：
With the example of the water supply engineering planning of small towns in southern china, the effects of town water consumption forecast, water resource selection, water site choice, pipe network planning on the present engineering planning of water supply were investigated. The analyses show that the water consumption forecast should adopt many kinds of methods to check each other, and finally determine a proper value. To ensure water yield of source water reliable and water quality to meet the requirements are the first principle of the water resource selection. The location of water plant should be determined according to the characteristics of the water source and the hydrological and hydrogeological conditions, in accordance with the relevant requirements specification. The basic requirements of the pipe network layout are as follows: the security of water quality; the reliability of the water volume and water pressure; the operation reliability and the least investment. As a part of the overall planning, the water supply engineering planning should proceed from reality to deal with the relationship of the recent construction and long-term development in order to push small towns economy to a rapid growth.
