BASIC STUDY OF ON-LINE BOD MEASUREMENT BASED ON RESPIRATORY RATE

In this article the principle based on BOD on-line measurement of respiratory rate is given first,using activated sludge reactor as the carrier(supporter).Then the yield coefficient needed in on-line measurement is fixed by the method of respiratory rate and the approach to on-line correction of saturation constant is presented.Finally it is proved that on-line BOD measurement based on respiratory rate is feasible basically by measuring BOD in manual make-up water of glucose as substrate and comparing result with theoretical analysis value.
