Abstract As a novel biological nitrogen removal process, partial denitrification coupled with anammox (PD-A)

process can save the cost of aeration and external carbon source, generate NO steadily and efficiently and have high

removal efficiency of total nitrogen. Besides, PD-A process can reduce the emission of greenhouse gas N O.

Existing researches on PD-A mostly focus on the simulated wastewater with single water quality conditions while
the research on the real wastewater is still missing. The mechanism and characteristics of PD-A process were
analyzed, the optimization strategy of PD-A process operation was proposed through comparing the optimal growth
conditions of core functional bacteria, partial denitrification bacteria and anammox bacteria, in combination with the
existing researches. Then the application cases of PD-A process in the real wastewater were analyzed. The results

beneficial to the efficient and stable operation of the process. PD-A process could achieve higher nitrogen removal
efficiency in the treatment of real domestic sewage, aquaculture wastewater and high nitrate wastewater, indicating
that the treatment of real wastewater through PD-A process was feasible. Finally, the development trend of PD-A
process was forecasted, the real wastewater should be treated, and the synergy mechanism of the core flora in the
system and the mixed biological denitrification control method should be further studied to improve the stability of
the process and the efficiency of synergistic removal of carbon and nitrogen.
