Abstract: To make the industry sustainable development, the Evaluation Standard for Green Industrial Building will be published in China. And the green lighting, as an important aspect of green industrial buildings has been emphasized in this standard. This paper introduces the green industrial buildings and the green lighting. The method of industrial buildings green lighting design based on DIALux has been proposed. The example of industrial building lighting based on green design is presented and simulation result shows that a large proportion of power consumption can be saved with ordinary metal halide lamps and symmetrical luminaries.

Abstract: This paper proposes a novel architecture of the three-layer cloud. And a practical industrial management system based on virtualization and cloud computing is presented. Since the current industry involves the utilization of various control systems and desktop systems, cloud computing provides us dynamic flexible infrastructure and QoS guaranteed services. With the development of virtualization and cloud computing, how to make the system flexibility and security is very important to industry. The presented system can be used for measuring the consumption of material and energy, monitoring the real-time state of the working environments and optimizing the process parameters.

Abstract: New complex inorganic ion exchanger AlTi(PO4)2.3333 is synthesized. Chemical composition, structure and some related properties and complex mechanism of this ion exchanger are investigated by electron microscopic, X-ray diffraction and chemical methods. The ion exchange behavior of AlTi(PO4)2.3333 has been studied in detail. Results of column test indicated, that the exchange capacity obtained from tests for Li+ in 0.1mol /L HNO3 solution is 4.9mmol/g.

Abstract: The ion-exchanger Al3Ti(PO4)4.3333 of inverse spinel type was prepared by a solid state reaction crystallization method. The Li+ extraction/insertion with this material were investigated by X-ray, FT-IR spectroscopy, and Kd measurement, The chemical analysis showed that the Li+ extraction/insertion be progressed mainly by an ion-exchange mechanism. The acid treated samples had an ion exchange capacity of 8.2mmol/g for Li+. It had a memorial ion-sieve property for Li+.

Abstract: Spinel-type metal oxides, magnesium-manganese- titanium oxide (MgMn0.25Ti0.75O3), was prepared by a coprecipitation/thermal crystallization method. The extraction/insertion reaction with this material was investigation by X-ray, saturation capacity of exchange, and Kd measurement. The acid treatments of MgMn0.25Ti0.75O3 caused Mg2+ extractions of more than 81%, while the dissolutions of Mn4+ and Ti4+ were less than 15%. The experimental results have proved that the acid-treated sample has a capacity of exchange 7.1mmol•g-1 for Li+ in the solution.
