| 初步探讨了营养源对异常酵母菌处理高含油废水系统的恢复能力。结果表明，废水中补充氮源可使酵母菌的油降解活性和沉降性能大大提高，有机物的化学需氧量、油去除率分别比不补充氮源时提高85％和88％；添加Ca2+ 对处理能力有一定提高作用，有机物的化学需氧量、油去除率分别提高了40％和47％；补充磷源和Fe3+ 对系统的恢复作用不明显。 |

| Abstract: |
| The recovery capabilities of nutrient source to the abnormal yeast-wastewater treatment system were discussed in small-scale experiments.The supplement of nitrogen source to wastewater can improve the oil degradation capabilities and sludge properties.The removal rate of COD and oil increased 85% and 88% respectively compared with that without any nutrient source supplement to wastewater.The supplement of Ca2+ played some roles in recovering the system and the removal rate of COD and oil increased 40% and 47% respectively.The recovery capabilities of supplement of phosphorus source or Fe3+ to system were not obvious. |
