Pulsed SBR Treatment of Municipal Sewage Denitrification and Experimental Research

Pulsed SBR process is a new type of SBR operation mode proposed against the traditional SBR process with poorer denitrification effect. This experiment is carried out at laboratory of sewage treatment, Beijing University of Technology, using real sewage for study, to study denitrification efficiency of pulsed SBR in nitration add raw water - denitrification this repeated and cycled process (with the same amount of water). The experimental results show that the effluent TN is less than 2 mg/L, removal efficiency is more than 96%.Keywords: pulsed SBR; domestic sewage; denitrification; experimental study
