Research progress of efficient biological nitrification processes

Efficient biological denitrification process is a research hotspot in the field of wastewater treat-ment, and biological nitrification is an important unit of the said process, which can remove ammonia nitrogen from wastewater effectively. Many efficient nitrification processes such as: complete nitrification process, full dose shortcut nitrification process, half dose shortcut nitrification process, and so on, were successively exploited by scholars in China and aborad, which promoted the development of biological denitrification technology for wastewater treatment. The principles, performances and operation parameters of complete nitrification process, full dose shortcut nitrification process and half dose shortcut nitrification process were summarized, the charac-terstics and advantages of the above processes were compared, which provided references for the development and application of efficient biological nitrification process.
