摘要：

An　innovative　technology　for　nutrient　removal　from　soybean　wastewater　was　developed　by　using　alternating　oxic/anoxic　operation　and　the　real-time　process　control,　and　it　was　combined　with　shortcut　nitrification-denitrification.　The　shortcut　nitrification-denitrification　was　performed　in　three　kinds　of　operation　modes:　shortcut　nitrification-denitrification　by　traditional　sequencing　batch　reactor　(SBR)　operation,　shortcut　nitrification-denitrification　by　alternating　oxic/anoxic　operation　under　the　fixed-time　control　and　shortcut　nitrification-denitrification　by　alternating　oxic/anoxic　operation　under　the　on-line　fuzzy　control.　Results　show　that　the　shortcut　nitrification-denitrification　by　alternating　oxic/anoxic　operation　under　the　on-line　process　control　is　the　best.　It　can　not　only　improve　both　nitrification　and　denitrification　rates　and　decrease　the　total　reaction　time,　save　the　carbon　source　and　alkalinity,　but　also　shorten　the　reaction　time　and　save　the　operation　cost.
