The construction of fuzzy controller of denitrification in SBR process and the choice of carbon addition method
SBR法反硝化过程模糊控制器的设计和碳源投加方式的选择

On the basis of the fundamental experiments, the fuzzy controller of denitrification in SBR was constructed, and the on-line fuzzy control experiments comparing three methods of carbon addition were carried out. The results showed a continuous carbon addition at a low rate was the best method, as it can not only give higher denitrification rate but also reduce the re-aeration time as much as possible. It appeared promising that pH and ORP were used as fuzzy control parameters to control the denitrification time and the carbon addition.
