摘 要: 利用数理统计方法对无催化-微波消解光度法测定炼油污水COD的可行性进行了分析。采用差数t检验法对无催化-微波消解光度法测定的炼油污水COD与传统回流法所测的COD进行检验,结果无显著差异;采用线性回归法检验,结果亦显著相关,表明无催化-微波消解光度法适用于炼油污水各处理装置出水COD的快速测定及预报。 The feasibility of COD determination in refinery sewage was analyzed by spectrometric method of catalysis-free microwave digestion with mathematical statistic method.The error t-test results showed that COD determined by spectrometric method of catalysis-free microwave digestion are identified with classical determination method,and test results of the linear regression method showed that they are identical.The spectrometric method of catalysis-free miˉcrowave digestion can be applied to determining and forecasting COD in refinery wastewater.
