【摘要】基于活性污泥2号模型(ASM2)对快速易生物降解组分(SS)进一步划分为可发酵的易生物降解有机物(SF)和发酵产物(SA),本研究提出了一套科学的表征方法。该方法涉及SS与XS(慢速可生物降解组分)的好氧呼吸测量同时表征、SA组分的离子色谱测定以及物料衡算。应用这套方法对重庆市某2个城市污水厂隔栅井出水水样平行进行了4组实验,各种组分测量值序列的CV值在2.09%～6.18%之间。更多还原

【Abstract】 A set of scientific characterization method was proposed in this paper based on that the rapid biodegradable component(SS) was further divided into fermentable rapid biodegradable component(SF) and ferment production component(SA) in ASM2.In this set of method the simultaneous characterization of SS and XS by hybrid respirometer,characterization of SA by ion chromatogram and the material balance method were involved.This method was applied to wastewater samples from the grille well of two different WWTPs in Chongqing and for each sample 4 parallel experiments was carried out,and the CV of the measured value sequences were between 2.09%~6.18%.更多还原
