摘　　要：将已知浓度的污染物石油烃加入到取自大亚湾大鹏澳天然海水中，进行污染物自净能力实验室模拟试验，探讨了各种条件下微生物对有机物降解的影响，用有机物浓度、ATP、DO、BOD5、COD 描述了有机物的降解过程。根据实验结果，得出 BOD5 和 ATP 可用来指示降解过程中微生物量的变化；此外，在一定条件下，石油烃的生物降解一级反应方程可描述为 OIL＝17.442 e－0.1949d 。In this paper, petroleum hydrocarbons are added to the natural seawater sample from Dapeng'ao, Daya Bay. The simulative experiment on self-purification ability of pollutant is carried out in the laboratory, and the influence on the degradation of organic matters by microbe under several different conditions is discussed and described with the concentration of organic matters, ATP, DO, BOD and COD. According to the experimental results, BOD5 and ATP may be used to indicate the change of the number of microbe during the degradation process. Under certain conditions, the equation of first-order reaction of biological degradation of petroleum hydrocarbon can be defined by the express on: OIL=17.442e-0.194 9 d.
