In this study, the effects of the operational parameters on the performance and practical application of the acclimated DPAO sludge using nitrite as electron acceptor were investigated. The results showed that anaerobic-anoxic-aerobic process was highly effective for the enrichment of nitrite-based DPAOs. Besides, a step increase of nitrite concentration in the feed was beneficial to improve the nitrite tolerance of DNPAOs. Practical application suggested that DPAO process was feasible for the post-treatment of UASB-SFSBR effluent during the piggery tail wastewater treatment. When the influent concentration of NO3--N、NO2--N and PO43--P were 5,70 ,30mg/L, respectively, the effluent could reach down to nearly 0of NO3--N and NO2--N, and less than 1.0mg/L of PO43--P.
