METHOD OF ANALYZING LIQUID MIXTURE IN WASTE WATER TREATMENT

摘要

[PROBLEMS] To provide a technique of analyzing the oxygen consumption amounts and the oxygen consumption speeds in the microbial degradation process of waste water components. [MEANS FOR SOLVING PROBLEMS] First, the oxygen consumption speed k<SUB>X</SUB>=KLa<SUP>.</SUP>(DOhf-highDO<SUB>X</SUB>) in the final block (block<SUB>X</SUB>) containing a single BOD component alone is determined by using an approximation formula to the dissolved oxygen level change curve and the formulae ?t<SUB>X</SUB>=t<SUB>X</SUB>-t<SUB>X-1</SUB> and BOD<SUB>X</SUB>=k<SUB>X</SUB>
