摘　　要：通过考察乙酸钠和葡萄糖两种单基质配水厌氧快速吸收COD去除情况、厌氧磷量变化、细胞内糖变化规律、混合液厌氧 pH值以及细胞外糖浓度与混合液COD的相互关系 ,证明对于糖类和非糖类基质 ,细胞都可以建立以内糖 (胞内单糖和糖元 )为厌氧吸收能量来源的机制。通过对比两种配水污泥驯化的难易程度、综合分析各方面数据 ,论证了当基质中含有糖类成分时 ,细胞可能优先利用单糖酵解产能 ,为厌氧快速吸收系统提供启动能量 ,从而缩短污泥驯化时间。由此提出当采用本文的厌氧快速吸收新工艺处理实际废水时 ,可依水质情况考虑投加适量能自发酵解产能的简单有机物 。Acetate and glucose were used as the main substrate in the experiment. On the basis of measuring and analyzing the anaerobic COD degradation and the variation of phosphate and intracellular carbohydrate content in anaerobic phase, it was verified that in both carbohydrate and non carbohydrate substrate conditions microbes could establish such a mechanism that intracellular carbohydrate could be utilized as the energy source of anaerobic absorption. Moreover, this paper suggested that bacterial cells might use the energy released by glucose glycolysis for start up of anaerobic absorption. As a conclusion, it was proposed that, according to the characteristics of the wastewater to be treated, adding some simple organic materials with the ability of self fermentation into the influent might help in speeding up the start up course of anaerobic absorption system.
