水质监测中BOD5与COD值相关性研究
STUDY ON THE CORRELATION BETWEEN THE DATA OF BOD5 AND COD IN WATER DETECTION
【摘要】 通过对大量水质监测数据进行分析整理,得出不同水质的BOD5 与COD值之间的线性回归方程,由线性回归方程预测出的BOD5 值进行验证,无论BOD5 与COD线性关系显著与否,若用预测的BOD5 值作为中间值,只需估算出一个稀释比就可以满足BOD的测定要求。
【Abstract】 The linear equations between the BOD 5 and COD values of several kinds of water were gained by processing a great deal of water quality data in foretime. BOD 5 values predicted by the equation were tested and verified. It is concluded that an estimated dilution ratio can meet the demand of the mensurement of BOD 5 with the predicted BOD 5 value as intermediate value whether or not the linear relation is notable.
