The effect of trace NO2 on anaerobic ammonium oxidation, methanogenesis and denitrification in separate system was investigated by batch experiment. Trace NO2 apparently enhanced the anaerobic ammonium oxidation, the function for NO2 apparently to enhance ammonium oxidation was suggested using the Haldane based model. The parameters were estimated, where the half saturate coefficient of NO2 was 2570...
According to small environmental capacity and fragile ecosystem of lake, take for the research object of lakes in Chongqing Section of three gorges reservoir area. Using the method of physical simulation, studied the effects of cold water discharge of lake water source heat pump systems on water quality. The results showed that cold water discharge lead to the water temperature decrease in local area...
Nitrogen-containing carbons have been made from different polymer precursors at 600 o C. Their composition and structure have been studied by chemical analysis, X-ray powder diffraction and X-ray photoelectron spectroscopy. These results show that this kind of carbon is disordered, and nitrogen exists as two kinds of forms in the polymeric carbons: graphene nitrogen (N 1s binding...
