自七十年代末期以来,国外力求寻找各种类型工业废水的BOD与COD等之间的线性关系,企图从概率统计方程中快速求得BOD_5值的最佳数学期望,因此,促进了预测预报BOD_5的发展。对于印染厂废水中的COD、TOD、TOC与BOD5的相关关系已有报道。 本文通过实例,论证了印染工业废水BOD_5与COD_(cr)、OD(耗氧量)有密切的相关性,并建立了BOD_5二元迴归统计方程。
Since the late 1970s, foreign countries have sought to find the linear relationship between BOD and COD of various types of industrial wastewater, and attempted to quickly obtain the best mathematical expectation of BOD_5 from the probabilistic statistical equations. Therefore, BOD_5 has been promoted for forecasting. development of. The correlations between COD, TOD, TOC and BOD5 in wastewater from printing and dyeing plants have been reported. This article demonstrates by example that the BOD_5 of printing and dyeing industry is closely related to COD_(cr) and OD (oxygen consumption), and establishes the binary regression statistical equation of BOD_5.
