摘要：

Since　eutrophication　has　become　increasingly　severe　in　China,　nitrogen　and　phosphorous　have　been　the　concern　of　wastewater　treatment,　especially　nitrogen　removal.　The　stabilization　of　the　intelligent　control　system　and　nitrogen　removal　efficiency　were　investigated　in　a　pilot-scale　aerobic-anoxic　sequencing　batch　reactor　(SBR)　with　a　treatment　capacity　of　60　m3/d.　Characteristic　points　on　the　profiles　of　dissolved　oxygen　(DO),　pH,　and　oxidation　reduction　potential　(ORP)　could　exactly　reflect　the　process　of　nitrification　and　denitrification.　Using　the　intelligent　control　system　not　only　could　save　energy,　but　also　could　achieve　advanced　nitrogen　removal.　Applying　the　control　strategy　water　quality　of　the　effluent　could　stably　meet　the　national　first　discharge　standard　during　experiment　of　10　months.　Even　at　low　temperature　(t　=　13°C),　chemical　oxygen　demand　(COD)　and　total　nitrogen　(TN)　in　the　effluent　were　under　50　and　5　mg/L,　respectively.　©　Higher　Education　Press　2007.
