摘要
本文分别研究了37℃BOD_1、20℃BOD_2以及COD与20℃BOD_5的相关性,得到了有关计算式;理论计算值与实测值吻合程度很好,并指出了三种判定方法的适用范围,为快速判定20℃BOD_5提供了理论依据.
The correlativities between BOD_2 at 20℃ and BOD_1 at 37℃,BOD_5 at 20℃ and COD in wastewater of food-stuff processing have been studied,from which evaluation formulaes are obtained.The theoretical results are shown to be in good agreement with the experimental ones.The scopes of application for three decision methodes arc also given through theoretical analysis.
