Study on Rapid Startup of Short Cut Nitrification and Denitrification
To find out affecting elements of short cut notification and denitrification, the fast startup and the stable operation of shortcut nitrification-denitrification has been investigated. It was found that the fast startup of shortcut nitrification-denitrification can be realized through the control of DO and pH as well as temperature. For the sludge in the primary shortcut nitrification, excess aeration has side effect on nitrite nitrogen accumulation. Therefore the suitable controlling method not only can realize the shortcut nitrification denitrification, but also can maintain stable operation.
