摘要
通过炼油废水的紫外光谱吸收系数(SAK)与化学需氧量(CODcr)的相关性研究,提出了经处理后炼油废水的CODcr对SAK的回归方程和相关系数r。研究结果表明:可以由废水的SAK值估算CODcr值,将SAK做为炼油废水有机物污染程度的参照指标,以使掌握炼油废水有机物污染状况的工作简化。
This article studies the correlation of ultraviolet absorption coefficient (SAK) with chemical oxygen demand (COD)of refinery wastewater through experiments, points out that when λ=210nm, the regression equation of COD to SAK of treated wastewater is C=2. 59+0. 920 s, the correlation coefficient r=0. 9720. So it is possible to estimate COD by means of SAK easily.
