摘要
研究了武钢焦化厂生化处理后的废水中ＣＯＤ值与紫外吸光度的关系，并建立了回归方程，结果表明．当废水中的ＣＯＤ值在０～１００ｐｐｍ时的相对误差均<6．４％。
The relationship between COD value in waste water after bio-chemical treatment of the coking plant of Wuhan lron & Steel Complex and absorbency is studied, and the regression equation is established. The resu1ts show that all the relative errors are <6. 4% when COD value in waste water is in the rang of 0～l00ppm.
