Design of Sequencing Batch Reactors for Biological Nitrogen Removal from High Strength Wastewaters

摘要

This paper covers an evaluation of more than twenty full-scale industrial waste-water treatment plants employing sequencing batch reactor (SBR) process mainly for carbon removal and a pilot-scale SBR designed for carbon and nitrogen removal from tannery effluent. The study highlights the major features of the SBR technology and proposes a rational dimensioning approach for carbon and nitrogen removal SBRs treating high strength industrial wastewaters based on scientific information on process stoichiometry and modeling, also emphasizing practical constraints in design and operation.
