Abstract: This paper states a review on the rapid development of the corrugated cardboard at home and abroad, and gives an introduction of its environmental protection, economical practical advantages and remarkable achievements in the packing industry. Combining with international development trends, this paper points out that domestic design of the corrugated cardboard product is still in the early stage, and its application research should be strengthened. In the end, this paper combines with domestic and international outstanding design examples to analyze the application prospect of corrugated cardboard in the fields of social activity and public life.

Abstract: A novel Schiff complex DSHE-Zn prepared for alternating copolymerization of carbon dioxide and cyclohexene oxide (CHO). DSHE-Zn has been found to be a catalyst for coupling carbon dioxide and cyclohexene oxide to afford alternating copolymer, poly(cyclohexenylene carbonate) (PCHC). The structure of product was investigated by FT-IR and ¹H NMR

Abstract: SiO2/TiO2 composite mesoporous materials prepared by sol-gel method with bacterial cellulose（BC）as a surface esterification agent and porous template was as photocatalyst in the degradation of methyl orange（MO）in water under UV- irradiation. The results show that the best heat treatment condition is at 600°Cfor 3 h and the optimum content of SiO2 is 30% (30 denotes the weight percent of SiO2). The photoactivity of 30SiO2/TiO2 catalyst prepared with BC was much better than that of reference catalyst prepared with no BC. An addition of BC not only raises the adsorbability of the photocatalyst, but also effectively inhibits anatase-rutile transformation and effectively induce amorphous-anatase transformation of TiO2. The BET surface area of 30%SiO2/TiO2 composite mesoporous materials was the largest. The resulting mesoporous materials showed a high photocatalytic activity for the photodegradation of methyl orange in the UV-irradiation.

Abstract: In this work are presented research results of physical and chemical characteristics of carbon-containing catalysts on Tonkeris clay base. A magnetic property of these catalysts was studied. It was established that the structure of the catalysts are contains а nano-sized carbon particles in a different morphology. Gydrocracking processes were investigated on the bases synthesized catalysts.

Abstract: In this work, Ammonium Molybdophosphate (AMP) was synthesized and the adsorption of Cs onto it under different initial pH conditions was investigated. The results show the negative effect of the hydronium and hydroxyl irons on the uptake of Cs while the iron-exchange capacity can reach 144.8 mg/g. In addition, the structure differences between AMP samples before and after Cs adsorption were examined by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and Raman technique. The results show that the Keggin structure of AMP stayed unchanged while new bonds arose after the Cs adsorption.

Abstract: In our country, high fluoride containing groundwater is general. Now,there have been some study on fluoride containing groundwater, but MgSO4 is the first use. In this paper,therefore,study a new method for removing fluorine from groundwater with MgSO4 , CaO powder regulate pH, studies the influencing factors of fluorine removal rate, such as pH,temperature and so on, obtain the proper treatment condition:8% MgSO4 solution 10ml, CaO powder regulate pH11,stir 5min at 40°C. Using this method, the concentration of fluorine ion in the groundwater is lower than the national provided drinking water criterion of <1.0mg/L, fluorine removal rate reach 93%.

Abstract: Oily sewage is one of the wastes produced in the oil industry production process and its quantity has been increasing year by year, which influences the environment and human health severely. Electric flocculation method is one of the wide application electrochemical treatment technologies for the oily wastewater treatment at home and abroad, which has higher efficiency than other technologies at the aspect of the organic pollutants degradation. A simulative experiment device dealing with heavy oil sewage by the electric flocculation method has been designed in this paper. The mechanism of the electric flocculation method in removing organic matter of the heavy oil sewage by analyzing the change of the composition and content of the organic matter in water samples before and after the process of the electric flocculation has been studied. Research results show: the carbon/tin dioxide electrode is better than the carbon/ ruthenium dioxide electrode in removing organic matter; most alkanes matters in the oily wastewater have been removed in the dispersing oil form by the electric flocculation; as the current density increases, the types and quantity of the response organic matter can be improved while types of the new synthetic organics increase. At the same time, this paper provides a theory support in specific optimization of the electricity flocculation flotation in oily wastewater treatment technology and process.

Abstract: Supported Fe-doped TiO2 has been prepared by a sol-gel method through the use of porous diatomite. The synthesized Fe-doped TiO2/diatomite composites were characterized by SEM and EDX techniques. The composite presented in this study showed higher adsorption and photodegradation ability of Rhodamine B than TiO2/diatomite and diatomite. It was found that the decolorization efficiency were dependent on the operational parameters of pH, photocatalyst dosage and dye concentration, and about 85% of the initial 50 mg/L dye could be adsorbed and degraded in 240 min. Moreover, kinetic study indicated that the photocatalytic degradation process could be described by the Langmuir-Hinshelwood model.

Abstract: Tourism is sensitive to global climate change and greenhouse gas emissions generated by the energy consumption restrict the sustainable development of tourism industry. Methods trying to make the tourism development of sustainability measurable are too confused to be of practical value. To overcome this obstacle, this paper built a Tourism Carbon Footprint Model based on energy consumption structure. With this TCF model, we analyzed carbon footprint of Huangshan between 2006 and 2009. We find that: (1) total carbon footprint of Huangshan increases from 2674.92 hm2 to 3456.76 hm2 at the annual rate of 7%; (2) energy consumption carbon footprint differs significantly in structure. The five kinds of energy carbon footprint, in the descending order, are the electricity, coal, diesel, gasoline, liquefied petroleum gas; (3) analysis of energy consumption carbon footprint shows that Huangshan is sustainable between 2006 and 2009.

Abstract: Lanthanum doping TiO2 powders were prepared using sol-gel method, and characterized by XRD. The doping quantity, time of solar irradiation and the added quantity of catalyst were investigated for the influence on the photocatalytic degradation of bisphenol A. The results show the structure of La3+ doped TiO2 powders were anatase, particle size were 16 nm. For the initial concentration of bisphenol A solution were 50 mg/L , when the doping quantity of La were 1.0 wt %, the dosing quantity of TiO2 were3.6 g/L, PH value were acid, irradiation time were 2 h, the photocatalytic activity of TiO2 was the best.
