摘要：

Dissolved　Oxygen　(DO)　is　one　of　critical　factors　influencing　substrate　degradation　and　nitrification　rates　in　activated　sludge　process.　A　two-step　nitrification　model　describing　the　aeration　period　of　the　sequencing　batch　reactor　(SBR)　operation　is　developed.　Parameter　estimation　of　this　model　using　the　DO　data　determine　the　stoichiometry　and　kinetic　parameters　as　well　as　the　initial　value　of　main　nutrients,　including　readily　biodegradable　substrate,　ammonia,　nitrite　and　nitrate.　Only　if　the　parameter　estimation　is　implemented,　reaction　related　substrates　can　be　predicted　if　new　initial　values　are　given.　With　optimal　DO　data,　this　paper　pointed　out　that　without　initial　value　monitoring,　both　of　the　parameter　estimation　and　prediction　of　the　main　nutrients　profiles　can　be　done　through　a　simple　method　based　on　a　global　parameter　estimation　algorithm.　©　(2012)　Trans　Tech　Publications,　Switzerland.
