【摘要】 采用TOC、UV自动分析仪测定地表水、污水处理厂排水和不同行业的工业废水中的TOC和紫外吸光度,并用国家标准方法测定相应的COD值。将获得的数据运用数理统计的方法加以分析,结果表明污水处理厂排水的TOC与COD之间以及紫外吸光度与COD之间均存在显著的相关性,相关系数在0.895以上(显著性水平α=0.01,样本数为20);地表水和工业废水不同程度上也存在类似的结果。该研究对有机污染物的排放实施总量控制具有重要意义。更多还原

【Abstract】 Total organic carbon (TOC) and UV absorbance in surface water, sewage effluent and different kinds ofindustrial wastewater were determined by TOC automatic analyzer and UV automatic analyzer, and simultaneously COD wasmonitored by national standard method . After analyzing the data by mathematical statistics, the results showed that therewere significant correlations between TOC/UV absorbance and COD in sewage effluent, the correlation coefficients wereabove 0.895 (α= 0.01,20 samples). The similar results were obtained in surface water and industrial wastewater. The researchwas very important to the total amount control of organic pollutants.更多还原
