摘要：
Photocatalytic technology is a valid solution for the remediation of wastewater containing uranium. In this study, the synthesis of Z-scheme g-C3N4/TiO2 catalysts was made by a thermal synthetic approach for photocatalytic U(VI) reduction. The characterization results revealed the successful synthesis of g-C3N4/TiO2 nanostructures. The g-C3N4 surface was uniformly coated with TiO2 nanoparticles. The depletion of U(VI) in water evaluated the photocatalytic activity of g-C3N4/TiO2 under UV light irradiation. The photocatalytic tests showed that g-C3N4/TiO2 exhibited more effective photocatalytic activity than the raw materials (1.64 and 56.97 times higher than TiO2(P25) and g-C3N4, respectively). Besides, a pseudo-first-order model was followed by the experimental kinetic data for the photocatalytic process. Moreover, g-C3N4/TiO2 still presented high photocatalytic activity after four reacting cycles. Based on these experiment results, the improved photocatalytic activity could be attributed to the Z-scheme mechanism, which decreased the recombination of photo-produced electrons and holes. The synthesis of these g-C3N4/TiO2 nanomaterials provides a facile and inexpensive method for treating wastewater containing U(VI).

摘要：
Both bioretention and sludge biochar have better effects to the removal of nitrogen and phosphorus removal in water.Combining them coulid improve the effect of bioretention on NH4+.After applying sludge biochar, the adsorption effect of filler on NH4+ was improved.When the sludge biochar was applied to the filler,on the top of the submerged area in the tank,the removal rate of NH4+ could reach 88.62%similar to 94.48%.

摘要：
This research inclines to study the ramification on arbuscular mycorrhizal fungi (AMF), including Glomusclaroideum (G. claroideum) and G. mosseae strains as well as the repair process of perennial ryegrass (Lolium perenne L.) in the uranium-containing soils. Three times at 120 degrees C for an hour was required to disinfect the soil mixture. Spraying the uranium (U3O8) into the soil mixture and mixing until the ingredients were thoroughly blended,serving the purpose of obtaining the uranium-containing soil mixture with 5 mg/kg U3O8. A week later, AMF was inoculated into every flowerpot and chamber facility. Seeds of perennial ryegrass were cultivated with thirty seeds in each flowerpot or each indoor equipment in a fortnight's time.Perennial ryegrass plants tended to be harvested after sowing and meeting the conditions of 60 days.Three substances are detected by three different detection means(Photosynthetic pigments, soluble proteins, and malondialdehyde correspond to ethanol extraction method, Coomassie brilliant blue method, and thiobarbituric acid method, respectively). Additionally,testing included activities of alkaline phosphatase and succinate dehydrogenase as well. Moreover, Hitachi H-7650 transmission electron microscope performed the function of observing cellular and subcellular distributions of uranium in plant epidermal cells.Photosynthetic pigment standards of perennial ryegrass are subject to AMF,which not only has a tendency to enhance the soluble protein levels in perennial ryegrass,but also gains the possibility of holding up the uranium-induced improvement of malondialdehyde levels in perennial ryegrass. G. mosseaes is properly more efficacious than G. claroideum in the attenuation of uranium damages in cell structures of perennial ryegrass. Our results demonstrate that AMF is capable of developing the capacity of perennial ryegrass on repairing the uranium-related soil contamination.
