摘要
通过研究提出一种快速确定进水溶解性COD中易生物降解部分SS 的物理 化学方法。该方法以絮凝为主体 ,将可通过 0 4 5 μm滤膜的胶体物质进行絮凝沉淀 ,然后再辅以质量良好的滤膜过滤 ,二者结合可有效测定SS 值。研究结果表明 ,絮凝方法和呼吸计量法所得出的结果具有较好的相关性 ,SS(OUR)约等于 0 81SS(floc)。滤膜质量对测定结果影响很大 ,如果没有质量良好的滤膜 ,建议采用单一絮凝方法直接测定进水中的SS。
A physico-chemistry based fast measurement to determine the bio-degradable content of soluble COD in inlet raw wastewater has been advanced. Flocculent was adopted to determine Ss, by this way: the 0.45 μm penetrating colloids were flocculently settled and then fine membrane filtrated. The determined Ss by floc is correlated to that by respirometry, about 1 Ss (respiratory)=0.81 Ss (floc). The quality of the membrane causes tremendous influence to the determination. In case when no high quality membrane obtained, it is proposed to examine the Ss by single flocculent way.
