【摘要】 针对农药厂高、中、低浓度的三类废水,测定其COD与TOC,并对测定值进行一元线性回归分析。结果表明,有机物成分稳定的废水不管浓度高低其COD与TOC均具有显著的相关性,可以建立相应的回归模型,模型计算值与测定值相对偏差小于5%。更多还原

【Abstract】 The value of COD and TOC in pesticide organic wastewater was measured,including high,medium and low concentration. Unary linear regression analysis was carried out according to the above measured value. It proved that COD and TOC had the significant correlation if organic matter composition was stable, regardless of high or low concentration. The corresponding regression model can be established,the relative deviation between calculated values by the model and measured values was less than 5%.更多还原
