Advanced nitrogen removal from real municipal sewage by multiple coupling of nitritation, denitritation and endogenous denitritation with anammox in a single suspended sludge bioreactor

multiple coupling of nitritation, denitritation and endogenous denitritation with anammox (PNA-(E)PDA) was simultaneously achieved using a sequencing batch reactor by step-feed for the first time.本研究首次采用分段进水序批式反应器，同步实现了亚硝化、反硝化、内源反硝化与厌氧氨氧化（Anammox）的多重耦合过程（PNA-(E)PDA）。
