Abstract:

The short-cut nitrification process plays an important role in treatment of the wastewater with high ammonium-nitrogen concentrations or low ratios of carbon to nitrogen. The efficiencies of the short-cut nitrification process can be improved by some strengthening methods, which can be more widely applied. The strengthening methods of short-cut nitrification including selection of suitable reactor configurations, introduction of ultrasound/magnetic field and addition of chemical reagents are introduced. The effects and mechanisms of these methods are analyzed. Furthermore, the application prospects of the strengthening methods and their technical problems to be solved are pointed out.

Key words: short-cut nitrification, strengthening methods, biological nitrogen removal, process efficiency
