| Abstract: | In order to realize accumulation of nitrite during denitrogenating in shortcut nitrification and shortcut anti-nitrification for controling the type of nitrification reaction, some experiments were done. In these experiments, using SBR technique, pH value effect on shortcut nitrification to municipal sewage which had not contained seawater and had contained 30% seawater. The results of experiments indicat that shortcut nitrification can uncertainly be achieved in treating municipal sewage without seawater to raise only the value of pH to raise the eoncetration of free ammonia,shortcut nitrification can be achieved in treating municipal sewage containing 30% seawater, and seawater is a factor of effect on shortcut nitrification. |
