| 摘 要： | 采用悬浮培养测定法，讨论了ＢＤＯＣ测定中动力学特性，得出在２８ｄ测定中ＢＤＯＣ的降解动力学满足一级反应，动力学方程为ＢＤＯＣｔ＝ＢＤＯＣｕ（１＝１０＾－０．０７７ｔ），降解常数ｋ＝０．０７７ｄ＾－１，通过比较实测的ＢＤＯＣ３和据公式计算出的ＢＤＯＣ３，证明这种动力学关系基本正确。

| Abstract: | Kinetic characteristic of measurement for Biodegradable Dissolved Organic Carbon (BDOC) in the incubation period was studied by determined the DOC every two days in 28 days. The kinetic equation is showed as BDOCt=BDOCu(1-10-0077t),k=0077d-1 which is lower compared to the k=01d-1 in BOD determination. The result was confirmed by comparing the BDOC calculated through kinetic equation and determined in experiment respectively. Furthermore, BDOC3(incubation period is 3 days) is about 40% of BDOC28(incubation period is 28 days). Based on the study, it is suggested that BDOC3 should be tested to substituted for BDOC28,which will make the BDOC measurement more feasible and sensitive. |
