Treated with nano-technology is also cleaner than tap water sewage
Using the system is stepping up its installation and commissioning, is expected to be completed in the last month. Into use, this daily treatment capacity of 3,000 tons of 60% of the sewage system can be reused to enable enterprises to 1,800 tons a day to save water,[link widoczny dla zalogowanych], reduce the cost of 1 million yuan per day. According to EPRI, Ningbo Branch of military resources is responsible for sewage treatment equipment technology research and development of Dr. Zhou Yusong project description, the system is different from the general waste water treatment technology's biggest innovation is the application of advanced membrane materials and appropriate technology. The role of membrane material is like ~ the sieve, but this \They are satisfied that the application is an advanced membrane and reverse osmosis membranes, are nano-scale membrane separation materials. Reverse osmosis membrane through which the smaller particles, to a certain pressure, the water is about 99.5% of sodium ions can not pass particles larger than the sodium ion can not by these \pure water. Treated water of low hardness, is already higher than we usually use tap water but also clean,[link widoczny dla zalogowanych], can be recycled. It is understood that the sewage treatment and utilization technology together the first of its kind in the country. From \nano-materials of platinum catalyst in the preparation of a major breakthrough. Chemistry and Chemical Engineering, Xiamen University, Solid Surface Physical Chemistry, State Key Laboratory of Professor Sun Shigang team led by Professor Wang Zhonglin with the Georgia Institute of Technology, who worked closely for over a year, was recently developed to control the nanocrystal surface structure and growth new electrochemical method, synthesis of twenty tetrahedral platinum nanocrystals. It is reported that twenty tetrahedral platinum nanocrystals crystallization of a relatively rare way, the surface structure of high-index facets. The crystal structure can improve the catalytic activity and stability, its catalytic activity is commercial platinum nano-catalyst 2 to 4 times, can improve the catalytic efficiency and extend service life. Experts believe that the birth of a new preparation method for the platinum catalyst nano-materials research provides a new way, and shows that its fuel cell, petrochemical, automobile exhaust and other important areas of application. Excerpt from \Nanotechnology Standards Working Group and other aspects of cooperation, seize opportunities nano-industrial development. \initiative in the market. \Under the agreement, USTC based high-tech advantages, mainly responsible for the high-tech, including nanotechnology,[link widoczny dla zalogowanych], including research and innovation; Provincial Institute of Standardization of standard resources,[link widoczny dla zalogowanych], do research projects and development standards. In addition, the two sides will jointly carry out training work for the provincial research institutes and enterprises involved in the development of international or national standards for personnel training. From the \ceramic nano-composite material of rubber. In 2005, in the tripod joint stock company and the Anhui University of implementation of the national scientific and technological issues - rubber nanocomposites rubber parts and automotive product development. Last year and a half,[link widoczny dla zalogowanych], the research group with excellent performance rubber prepared ceramic nanocomposites, first developed in the domestic and international car shock absorber oil seals, wear-resistant EPDM rubber hose, rubber shock absorbers with three car stop the main components of rubber products. Statutory inspection bodies by the National Institute of Shanghai Testing Center of rubber products, automobile shock absorber oil seal life up to 15 million times more life expectancy than similar domestic products 3 to 5 times higher, but also significantly better than similar foreign products. EPDM rubber hose wear life of more than 100 million, ranking the international advanced level. Automotive shock absorber rubber stopper substantial increase in dynamic endurance to reach the domestic advanced level. Currently, three products have been small series production.
