【Abstract】 In this artcle,through theory and practise the twosides,we seek after a simple reckon method of sample’s delution multiple in the determining of BOD5,Atfirse,we determine the value of CODcr,then multiply the quetiety 0.15 by the CODcr,namely we obtain a dilution multiple The result shows that this method has many merits,as the better dependability,the higher veracity,the stronger applicability etc it is the same with the analysis monitoring of BOD5 in the industrial waste water and it has the practicl meaning.更多还原
