Abstract
本文主要是探討B O D的動力學模式，因B O D值愈高表示有機性?染物的含量愈多，而標準B O D試驗以溫度20℃培養5天所消耗的氧量表示，因此B O D試驗需培養5天，時間太長為其缺點，故本實驗利用短期B O D t值推估標準BOD?之可行性做探討，以學校的餐廳廢水為例，其二階動力學方程式的速率常數K之平均值為0.0005 1∕日．B O D，再利用K值由B O D t值推估B O D?值，實際結果顯示，餐廳廢水的培養時間可縮短至一天，而平均誤差僅為3％，由此可知利用短期B O D t值推估B O D?有很高之可行性，在實驗上並可減少分析時間及節省設備空間。
This article is aiming at research for the Kinetic Model of R.O.C., in consideration of the fact that the higher the B.O.D. value, the more contents will be the organic pollution. Since standard B.O.D. test is to be shown by cultivating 5 days the consumption of oxygen quantity at the temperature of 20°C, B.O.C. test should cultivate 5 days, and too long time should be a deficiency. Therfore, the current test is to research the possibility of applying short period. B.O.D. t value to estimate the standard B.O.D. 5. Taking sewerage of the school mess hall as an example, the average value of Rate constant K of the second order reaction is 0.0005 1/day. R.O.D. and then by applying K value of B.O.D. t value to estimate R.O.D. 5 value, the actual result shows that the cultivating time of sewerage of the mess hall can be 1 day, and the average tolerance appears to be only 3%. Accordingly, there is pretty high possibility to estimate P.O.D. 5 by applying short period B.O.D. t value, and by doing this way, it may lessen the analysis time and save the equipment space as well in the test.
