TL;DR: In this paper, the authors used three dimensional excitation-emission matrix (EEM) fluorescence spectroscopy to detect dissolved organic matter (DOM) in a typical operation cycle for the first time, demonstrating that DOM increased during the anoxic phase and facilitated the reduction of excess NO 3 -N by denitrification.

TL;DR: The microbial diversity analysis revealed that Proteobacteria was the most abundant phylum and among the 108 genera detected in this ED system, the genera responsible for denitritation were Thauera, Paracoccus, Ottowia and Comamonadaceae_unclassified, accounting for 46% of total bacteria.

TL;DR: The results show that COD from mature leachate did not bring obvious inhibition effects to anammox, and under concentrations of influent ammonia and COD, the removal efficiencies of TN and C OD reached 94% and 62% respectively.

TL;DR: An innovative step-feed partial nitrification, simultaneous Anammox and denitrification (SPNAD), equipped with real-time control parameters, achieved efficient nitrogen removal from raw mature landfill leachate.

TL;DR: A novel partial nitrification-Anammox biofilm reactor (PNABR) operated under high dissolved oxygen (DO) with pre-anoxic - aerobic - anoxic operational mode was developed for efficient denitrogenation from mature landfill leachate.
