造纸废水中的COD_(Cr)快速预测方法研究

Research on Rapid Forecast Method of COD_(Cr) in Waster Water from Paper Making

以造纸厂排水渠各监测点废水的测定结果为基础 ,进行回归分析。找出了化学需氧量 (简称CODCr)与悬浮物 (简称 SS)之间的线性关系 ,建立了回归方程 ,从而得出利用测定 SS的量来预报CODCr的简便方法。该方法预报误差在± 10 %以内 ,便于对造纸废水 CODCr的监测与宏观控制 。

The determination results of waster water from different escape channels were regressed.It was found that there was a linear relationship between chemistry oxygen demand (COD Cr ) and suspended substance (SS).The regression equation was found which indicated that COD Cr could be forecasted rapidly from the analyzing results of SS.The error of this method could be controlled within 10 %,and it was convenient to supervision and macracontrol of COD Cr .Thus, this methods is practical.
