| Abstract: | The comparison of shortcut nitrification-denitrification technology with the traditional technology was made. The mechanism and characteristics of the shortcut nitrification-denitrification technology were described. Several factors affecting NO2-N accumulation, including temperature, dissolved oxygen concentration, pH value, free ammonia concentration and sludge retention time, were analyzed. By comparison with the typical processes, the existing problems and several suggestions for this technology were presented. |
