1New Applications of Nano Titanium Dioxide显示文摘New applications and research progress of nano titanium dioxide(TiO2) in coating,environmental protection,chemical industries,cosmetics industry,electronic industrial products,medicine,health and food processing fields were summarized in the paper.The results showed that nano TiO2 is the most dynamic one in the new nano material study today,which will have a very important impact on our social economic development in future.The research and utilization will give people's lives enormous changes.TANG Xiao-hong WU Chong-zhen LI Bao-jun LI Cheng-wei LIN Yu 2012Meteorological and Environmental Research2012,3,1:1
2Study on Pre-treatment of the Domestic Sewage by Water-dropping Aeration Zeolite Bed Technology显示文摘[Objective] The research aimed to study pre-treatment effect of the domestic sewage by water-dropping aeration zeolite bed technology. [Method] By water-dropping aeration manner, we conducted sewage reoxygenation. Zeolite was used to replace traditional contact oxidization filler. We inspected oxygenation effect of the water-dropping aeration manner and removal efficiency of the pollutant in sewage after biological contact oxidation. [Result] Under the experimental condition with water-dropping heights of 0.30, 0.45 and 0.60 m, average added values of the dissolved oxygen for raw water were respectively 2.4, 3.6 and 4.2 mg/L after water-dropping aeration. Under the situation with average HRT of 2 h, when COD, TN and TP of the influent were respectively 309.0-464.0, 33.3-95.0 and 4.0-7.5 mg/L, their corresponding average removal rates were 47.25%, 46.39% and 40.75%. [Conclusion] The research conducted useful attempt for high-efficiency and low-cost treatment of the domestic sewage in rural area.GAO Chang-fei 2012Meteorological and Environmental Research2012,3,10:0
