Biological reactor treatment for effluents with nitrogen concentrations uses feed phase cycles based on set formula

摘要

#CMT# #/CMT# The treatment procedure uses the oxidation of ammonia into nitrites followed by denitritation into gaseous nitrogen in a sequential biological reactor with nitrifying bacteria in conditions that promote the action of nitriting bacteria and inhibit the action of nitrating bacteria. The procedure is carried out in cycles divided into sub-cycles of feed and aeration phases. The minimal number of feed phases in a cycle is determined by a formula based on the daily nitrogen charge divided by the concentration of ammonia in the effluent leaving the reactor, the minimal liquid volume the number of complete sequential biological reactor cycles in a day, and the concentration of inhibiting ammonia. #CMT#USE : #/CMT# Treatment of effluents containing concentrations of nitrogen. #CMT#ADVANTAGE : #/CMT# The procedure eliminates the nitrogen concentrations by means of nitritation/denitritation cycles. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flow chart of the effluent treatment procedure.
