Abstract
Abstract
The stability of the ANAMMOX (Anaerobic ammonium oxidation) process for the side-stream has been proven worldwide, but the stability for the mainstream has not yet been proven. Most studies in previous mainstream ANAMMOX research have only focused on nitritating ammonium nitrogen at a low concentration. This study did not nitritate low-concentration nitrogen during the mainstream ANAMMOX process, but changed the idea to bringing the nitrite source from the recycle water. Since the recycle water contains a high concentration of nitrogen, nitritation reaction is stably induced, and the nitrite nitrogen is used as a substrate source necessary for the mainstream ANAMMOX reaction. In this study, the results of about 1500 days of successful operation at the lab scale were summarized, and the necessary operating factors and data were successfully derived at the real scale.
