Popis: Long period start-up is one of the main restraining factors of the single-stage completely autotrophic nitrogen removal over nitrite (CANON) process.This study investigated the fast start-up of the CANON process initiated by a submerged biological aerated filter (SBAF) method.With conventional activated sludge from the secondary sedimentation tank of municipal waste water treatment plants as the seed sludge,the CANON process was successfully started up after the acclimation of sludge microorganisms for 48 days under the experimental conditions of (30±2)℃,organic carbon free and controlled dissolved oxygen (stage Ⅰ:0.3-0.5mg·L
