Roles of waste iron scraps (WIS)-addition in anammox system treating sulfide-containing wastewater: Alleviating sulfide inhibition, promoting novel anammox bacteria enrichment, and enhancing nitrogen removal capacity
This study comparatively investigated the stability performance and nitrogen removal effect of the Anammox system after adding waste iron scraps under conditions of low sulfide concentration. The aim is to provide a theoretical basis for the application of Anammox processes in sulfide-containing wastewater and further expand the practical use of Anammox processes.
