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

The construction of fuzzy controller of denitrification in SBR process and the choice of carbon addition method

在大量试验的基础上构建了SBR法反硝化过程的模糊控制器 ,并进行了 3种碳源投加方式的实时控制试验 .结果表明 ,按较小的速率连续投加碳源是最佳投加方式 ,它不仅可以满足反硝化速率上的要求 ,还可以尽量地减少再曝气时间 .

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.
