摘要: Abstract To investigate the effect of sludge ratio on hybrid CANON system, autotrophic nitrogen removal was inoculated with different granule/floc ratios to initiate and maintained during operation process. The start-up performances were compared, distribution characteristics functional bacteria investigated. results show that Equivalent system (granules:flocs = 1:1–1:1.5) successfully started-up day 19, rate (NRR) reached 0.299 kgN m−3·d−1 63. At same time, it less affected by load shock than High-granules High-flocs systems. Therefore, had strongest performance. activities conformed spatial heterogeneity, unlike abundance. With increased floc proportion, difference in activity abundance anaerobic ammonium-oxidizing (AAOB) between granules flocs increased, while there a decrease aerobic (AOB). However, Nitrosomonas higher when proportion 50%. This study provides new ideas insights for fast can conform varying needs engineering applications.
