| 摘 要： | 以北方某污水处理厂(A/O工艺)剩余活性污泥为研究对象,考察了超声波与生石灰联合预处理对后续剩余污泥两相中温厌氧消化的影响,结果表明:两相反应器内污泥絮体被充分破坏,厌氧消化过程中在产酸相和产甲烷相内,NH3-N浓度均有提高,但是没有出现磷的显著释放。

| Abstract: | Based on municipal Waste Activated Sludge（ WAS）obtained from WWTP（ A/O process）in north,the effects of combined pretreat-ment of ultrasound together with CaO were investigated on subsequent two-phase mesophilic anaerobic digestion. The results show that the sludge flocs are completely broken down in two phases by Scanning Electron Microscopy（ SEM）analysis. NH3-N concentrations in two phases are en-hanced during anaerobic digestion. However,there is no significant phosphorus release in two phases. |
