摘　　要：通过对某生活污水处理厂氧化沟中水质的监测数据进行统计、分析,探讨了主要污染指标在系统运行过程中的相关性。通过对其进行回归计算分析后,发现它们之间有着较为明显的线性相关性。其中出水指标回归计算及检验结果如下:BOD5、SS、TN、TP与CODCr之间的相关系数r分别为0.9612、0.9675、0.9541、0.8705,检验值F都大于F0.01。据此若测得一指标后,可以利用其相关性,换算出其它指标的量值,从而减少监测项目。The correlation of the monitoring datas of the water quality during the oxidation ditch process operation in a domestic sewage wastewater treatment plant were statisticated and analyzed, the relativity of the main pollution indexes during the system operation was discussed. Through the analysis of its regression calculation, it was found that linear correlation of those indexes was very obvious. The results of the regression calculation and the examination of the indexes of the effluent water showed that： the correlation coefficient r between BODCr, SS, TN, TP and CODCr were 0.961 2, 0.967 5, 0.954 1, 0.870 5 respectively, and the test value Fwas greater than F0.01. Therefore, when a normal index was gotten from the test, based on the correlation, the other indexes could be obtained through the conversion, the monitoring items would be reduced.
