Method and Apparatus of Nitrogen Removal from the Recycle Water in the Sewage Treatment Plant

摘要

Digestion supernatant according the number of wake in the aqueous phase, concentrated supernatant, and separated by desorption filtrate nitrogen removal of sewage treatment plants wake that enables to remove nitrogen according to the amount and density characteristics method and relates to an apparatus, such a sewage treatment plant method for removing nitrogen in the wake can, and the device nitrite the C / N ratio is low desorption filtrate was than concentrated supernatant, or digestion supernatant and the mixture of desorbed filtrate and containing a high concentration of nitrogen than the concentrated supernatant, so the nitrogen concentration of the concentrated supernatant from the aerobic Chemistry by and denitrification by using its own carbon source of the concentrated supernatant to be added in an oxygen-free state, as well as the ammonium nitrogen of the concentrated supernatant is organic matter decomposition takes place by screen nitrite to failed to remove ammonium nitrogen in the aerobic external carbon source in anaerobic conditions with this stable denitrification treatment sikimeuroseo Eojim as well as being able to be effective to improve the processing efficiency.
