Nanometer-sized TiO2 thin films were prepared by sol-gel processing. Photocatalytic degradation of tannery wastewater has been studied by using the TiO2 films as photocatalyst. In the static experiments, by using the low pressure UV as light source, the best condition is that the time of light-catalyzed is 4 hours, initial pH is 6.7 and the volume of H2O2 is 0.3% (v/v). Then, we carried on the dynamic...
On the basis of analysis of ash-water from Baoding power plant, chemical components of underground water and the condition of environmental hydrology the prediction on pollution from ash-water permeation was carried out by applying one- dimensional homogeneous mathematical model. The results show that ash-water will not take bad influence on the water quality of water source of Baoding city to ash-field...
