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做为炼油废水有权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.

Abstract: 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. 920s,the correlation coefficient r=0. 9720. So it is possible to estimate COD by means of SAK
easily.
