Development on the Process for Nitrogen and Phosphorus Removal in Municipal Wastewater Treatment System

  • Published : 2003.06.01


The removal effect of total nitrogen in municipal wastewater by decreasing hydraulic retention time(HRT) from 6 hour to 4 hour on MNR process was not decreased.. The removal efficiencies of nutrient removal process combining A2/O process with media for T-N were 63.1% in the reactor operated 6 hour, and 73.5% in the reactor operated 5 hour and 77.0% in the reactor operated 4 hour.
