摘要
研究了预报造纸废水中化学需氧量(简称COD)的简便方法.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,具有较高的实际应用价值.
Seeking a simple method for determining the chemistry oxygen demand (COD) in the waste water from paper making. The determined result is based on adopting waste water samples from different points of the canals and conducting regression analysis. By finding out linear relation between COD\-\{Cr\} and SS (suspended substance) and setting up the regression equation, the simple method of for forecasting COD\-\{Cr\} is obtained. This method can control the forecast error within ±10% and be convenient to the supervision and macrocontrol for COD\-\{Cr\}. It possesses relatively high practical value.
